海外TECH	DEV Community	Build a custom video chat app with Daily and Vue.js	https://dev.to/trydaily/build-a-custom-video-chat-app-with-daily-and-vuejs-4952	Build a custom video chat app with Daily and Vue jsAt Daily we ve specifically built our video and audio APIs to be frontend framework agnostic This is to make sure developers can implement real time video calls ーa big feature in itself ーwith whichever JavaScript framework they prefer or no framework at all We ve spent a lot of time discussing React demos and sample code in our blog posts but React is not your only option for a framework Vue js for example is another great option that you can use with daily js Recently on the blog we looked at how to embed Daily Prebuilt in a Vue app Daily Prebuilt is our plug and play option for video calls which makes it the fastest and most convenient way to add video to your app In some cases however you may need more control over the video call designs or you might even be building something more custom like an audio only call app In cases like these using Daily s custom call object option gives you total control over the video and audio experience including the video call design and functionality In today s tutorial we ll look at building a custom video call app in Vue using Daily s call object Planning our app s featuresIn terms of functionality video call participants will be able to Join the call with video and audioControl their own video and microphones while in the call e g to mute themselves Share their screen on any browser that supports screen sharing We ll only let one person share at a time to keep things simple for nowSet their username for the call before joiningLeave the call whenever they wantBe notified when device permissions are blocked by the browser with instructions on how to permit device accessCommunicate via text chat in a custom chat box The details for this will be covered in a follow up post As is required for any app we also need to manage our feature scope In this case we won t worry about managing large calls in terms of performance optimization or the UI layout Those are big topics in themselves as demonstrated by this whole series on them Getting set up with DailyTo use this demo you will need a Daily room to join To get your own Daily room URL you ll need to create a Daily account Once you have an account and are logged into the Daily Dashboard you can create a new Daily room and copy its URL Note You can also create Daily rooms via the REST API Setting up your local dev environmentAs always we ve already built this app for you so ーif you like spoilers ーfeel free to clone and use the demo app via Github To run it locally enter the following commands in your terminal window yarnyarn startOpen the app at whichever port it s running which is likely http localhost More spoilers Looking at our component structureIt s often helpful to know the structure of what we re going to be building before diving in The App component is our entry point for our Vue app It will always render the AppHeader component and conditionally render either Call or Home depending on whether the user has joined a call Call is where daily js will be imported and where all the call s logic will be defined It is also the parent component for the rest of the components in the app Let s briefly define what each of these components does Loading This component contains an svg with a loading animation It shows when the user is joining a call i e in a loading state VideoTile This component is rendered for each participant in the call It will either render a lt video gt element or a NoVideoTile component depending on whether the participant has their video on An tag is rendered for each participant For local participants Controls is also a child component of the VideoTile That means everyone gets device controls for their own tile WaitingCard If you are alone in a call this component is rendered to let you know you are waiting for others to join ScreenshareTile When a screen share is started this component is added for the screen share track PermissionsErrorMsg If camera or microphone permissions are blocked locally this card is rendered instead of the call view so you know to update your browser permissions Chat This is where our chat messages will be sent and displayed Now let s see how these actually work Taking advantage of Vue s data objectOne thing you might notice looking at the code for this demo is that there s no state management library or dedicated backend instead we rely on Vue s data object to keep any information handy that needs to be referenced throughout the code base As you review each component in the rest of this tutorial be sure to look at each component s data method to see which values are being stored Okay get to the code alreadyNow that we know what we re building we can actually start coding it The App component Determining our in call stateThe main conditional we have in App is whether to show our home screen or the call UI The home screen is the default view when you visit the demo site It renders a form to join a specific Daily room The call UI is everything you see once you submit the form on the home screen to join a Daily room In App s template we represent this conditional by checking the value of appState a value on our data object lt template gt lt app header gt lt call v else if appState incall leaveCall leaveCall name name roomUrl roomUrl gt lt home v else joinCall joinCall gt lt template gt If appState equals incall we show our Call component otherwise we render our Home component Looking at the data object and methods in App the appState is initially set to idle on render When you join a call through the home screen s form appState gets set to incall Any time the call is left or refreshed appState gets reset to idle bringing the local user back to the home screen data return appState idle name Guest roomUrl null methods joinCall name url this name name this roomUrl url this appState incall leaveCall this appState idle joinCall gets called in Home and passes the two input values name and url as function parameters These are then set in App s data object and will get passed as props to Call to be used later by daily js That is really all that happens in App and Home so let s jump right to Call to understand how our video call functionality works Video call the radio star Letting participants join with video and audioWhen using Daily s call object like we are in this demo we need to manually add any elements we want present in our UI This is in contrast to Daily Prebuilt where it s all done for you That means we ll need to handle the following in our Call component Creating lt video gt and lt audio gt elements for any call participants who might have video or audio on In this demo that s everyone who joins If someone turns off their video we ll show a placeholder to avoid shifting the layout when video isn t available Creating a lt video gt element specifically for screen shares Adding a control panel for the local participant to toggle their camera and microphone share their screen or leave the call We ll also add some basic styling for group call layout management though we ll prioritize one on one calls to keep our CSS styles simpler to start The first step in the Call component is to initialize the call instance with daily js and to join the call so let s look at what happens when the Call component is mounted in the mounted lifecycle method data return callObject null participants null count messages error false loading false showPermissionsError false screen null mounted const option url this roomUrl Create instance of Daily call object const co daily createCallObject option Assign in data obj for future reference this callObject co Join the call with the name set in the Home vue form co join userName this name Add call and participant event handler Visit for more event info co on joining meeting this handleJoiningMeeting on joined meeting this updateParticpants on participant joined this updateParticpants on participant updated this updateParticpants on participant left this updateParticpants on error this handleError camera error device permissions issue on camera error this handleDeviceError app message handles receiving remote chat messages on app message this updateMessages Our three major tasks in the mounted method is to Initialize a new Daily call object using the Daily URL provided in the home screen formconst option url this roomUrl const co daily createCallObject option Join the Daily call using the username also provided in the home screen formco join userName this name Add our Daily event listeners to know when to update our call UI co on joining meeting this handleJoiningMeeting Daily events and their callbacksBefore moving on let s look at each of the callbacks attached to the Daily events mentioned above to understand how they impact our app s state The joining meeting eventjoining meeting gets called when the local participant is still joining the call This is like a loading state before being officially in the call co on joining meeting this handleJoiningMeeting handleJoiningMeeting this loading true In the handleJoiningMeeting callback we set loading in our data object to true so we know when to show our loading spinner in the UI The joined meeting participant joined participant updated participant left eventsIn this demo we keep an array of the current participants in our data object to iterate through in our UI That means we need to update our participant list whenever the participants have an event that will affect our list co on joined meeting this updateParticpants on participant joined this updateParticpants on participant updated this updateParticpants on participant left this updateParticpants All four of these events are handled by the same callback updateParticipants e Note In apps with large meetings you will likely need to set up separate methods for these events to avoid any unnecessary re renders updateParticpants e if this callObject return const p this callObject participants this count Object values p length this participants Object values p const screen this participants filter p gt p screenVideoTrack if screen length amp amp this screen this screen screen else if screen length amp amp this screen this screen null this loading false Here we get all the participants from the Daily call object with the participants method and convert it from an object to an array We also assign that array to our participants key in the data object for future reference If any participants have a screenVideoTrack it means they are screen sharing We then set the screen share in our data object to be accessed in our HTML Lastly we make sure we re not in a loading state which is technically only necessary the first time this method gets called The error eventThis is only called if the video call gets stuck in an unrecoverable state In an ideal world it would never get called but like all good programmers we cover every possibility co on error this handleError handleError e this error e errorMsg this loading false Here we set our error data object key to the error message provided by daily js and make sure we re not in a loading state The camera error eventFor daily js to access call participants devices like their camera and microphone it requires that call participants give it explicit browser permissions Without these permissions either at the start of a call or mid call the camera error event will get triggered co on camera error this handleDeviceError handleDeviceError this showPermissionsError true When a camera error i e device error happens we update the data object so that showPermissionError is true This will let us know when to tell our local participant to update their permission settings The app message eventco on app message this updateMessages app message gets called when a participant sends a message in the call via the sendAppMessage Daily instance method updateMessages e this messages push e data We ll discuss how chat works in more detail in a follow up post but for now it s important to know every chat message sent by a call participant is saved to the messages array in the data object That array can then be iterated over to display our full chat history in the chat box How our stored data impacts our rendered Call UIEach of these values we set in the data object are used to conditionally render different views in our call UI To start let s look our Call s template lt template gt lt main gt lt loading is true when the call is in the joining meeting meeting state gt lt template v if loading gt lt div class loading spinner gt lt loading gt lt div gt lt template gt lt template v else gt lt div class wrapper gt lt template v if error gt lt p class error text gt error lt p gt lt refreshing will leave the call and reset the app state gt lt button class error button click leaveAndCleanUp gt Refresh lt button gt lt template gt lt template v if showPermissionsError gt lt permissions error msg reset leaveAndCleanUp gt lt template gt lt template v else gt lt div class screen tile container tile container full height gt lt template v if screen gt lt screenshare tile participant screen gt lt template gt lt div class participants container v if participants gt lt template v for p in participants key p session id gt lt video tile participant p handleVideoClick handleVideoClick handleAudioClick handleAudioClick handleScreenshareClick handleScreenshareClick leaveCall leaveAndCleanUp disableScreenShare screen amp amp screen local gt lt template gt lt template v if count gt lt waiting card url roomUrl gt lt template gt lt div gt lt div gt lt template gt lt chat sendMessage sendMessage messages messages gt lt div gt lt template gt lt main gt lt template gt There are quite a few conditions here so let s break it down a bit When loading is true we show a loading spinner whereas when loading is false we show the call UI lt template v if loading gt lt div class loading spinner gt lt loading gt lt div gt lt template gt Next once we ve officially joined the call we conditionally show an error message and refresh button when error is truthy This is so the local participant can refresh the page if something goes wrong lt template v if error gt lt p class error text gt error lt p gt lt refreshing will leave the call and reset the app state gt lt button class error button click leaveAndCleanUp gt Refresh lt button gt lt template gt lt template v if error gt lt p class error text gt error lt p gt lt refreshing will leave the call and reset the app state gt lt button class error button click leaveAndCleanUp gt Refresh lt button gt lt template gt Next we want to show a message in our UI if the device permissions are blocked In some cases you may not want to prevent your users from seeing the video call just because their permissions are blocked but we do because we consider device permissions a requirement to use this app lt template v if showPermissionsError gt lt permissions error msg reset leaveAndCleanUp gt lt template gt Iterating over our participants arrayThe next block of elements in our template is where we render actual video tiles lt template v else gt lt div class screen tile container tile container full height gt lt template v if screen gt lt screenshare tile participant screen gt lt template gt lt div class participants container v if participants gt lt template v for p in participants key p session id gt lt video tile participant p handleVideoClick handleVideoClick handleAudioClick handleAudioClick handleScreenshareClick handleScreenshareClick leaveCall leaveAndCleanUp disableScreenShare screen amp amp screen local gt lt template gt lt template v if count gt lt waiting card url roomUrl gt lt template gt lt div gt lt div gt lt template gt The first section here renders a screen share tile anytime screen is truthy lt template v if screen gt lt screenshare tile participant screen gt lt template gt Next we render a VideoTile component for each participant in our participants array on the data object and pass any relevant information as a prop to be used in that component lt template v for p in participants key p session id gt lt video tile participant p handleVideoClick handleVideoClick handleAudioClick handleAudioClick handleScreenshareClick handleScreenshareClick leaveCall leaveAndCleanUp disableScreenShare screen amp amp screen local gt lt template gt Lastly we render an extra card if there s only one participant so they don t feel lonely while waiting lt template v if count gt lt waiting card url roomUrl gt lt template gt The very last component that gets rendered in our call UI is the Chat component which is included whenever you have officially joined the call It handles sending and displaying chat messages lt chat sendMessage sendMessage messages messages gt That was a lot to go through but we now officially have all our call UI included in our app Our next steps will be to take a closer look at VideoTile and ScreenshareTile to see how we turn the media tracks provided by daily js into actual video tiles in our app Call me a mason because we re about to lay some tilesOur VideoTile component is rendered for each participant and includes an lt audio gt element and a lt video gt element or NoVideoTile placeholder component For the local participant it also renders the Controls element When VideoTile mounts we do the following data return videoSource null audioSource null username Guest mounted this username this participant user name this handleVideo this participant this handleAudio this participant Set the username in our data object so we can display it in our tile UIHandle updating the video and audio elements with the tracks for this tile s participant methods handleVideo if this participant video return const videoTrack this participant tracks video persistentTrack const source new MediaStream videoTrack this videoSource source To get the participant s video playing in the component s lt video gt element we need to create a new MediaStreamby passing the participant s video persistentTrack and setting that as the lt video gt s srcObject For the participant s audio we do the same thing but with the participant s audio persistentTrack handleAudio if this participant local return if this participant tracks audio persistentTrack return const audioTrack this participant tracks audio persistentTrack const source new MediaStream audioTrack this audioSource source Once that is managed we can toggle our video and audio using the controls Adding a ScreenshareTileThe ScreenshareTile is almost identical to the regular VideoTile except it uses the screenVideoTrack instead of a persistentTrack handleVideo if this participant screen return const videoTrack this participant screenVideoTrack const source new MediaStream videoTrack this videoSource source We ve set up the ScreenshareTile to always show on top of the participants tiles but how you want to style it is completely up to you Wrapping upIf you re wondering about how Chat works we ll be sharing a follow up post soon that will do a deeper dive into how to quickly build the custom chat box included in this demo And remember this demo is just a jumping off point for all the custom UI you can build for video or audio only apps using Daily s call object mode It really can be as creative and custom as you d like If you want to expand on this app even more you could Add prejoin UI to test devices and see your local video before joiningAllow users to create rooms via the app UI using Daily s REST APIManage meeting permissions via room settings like making the call a broadcast call Time for a webinar anyone	2021-10-28 17:36:50

海外TECH	DEV Community	Análisis de sentimientos en una aplicación web con ML.NET	https://dev.to/esdanielgomez/analisis-de-sentimientos-en-una-aplicacion-web-con-mlnet-223n	Análisis de sentimientos en una aplicación web con ML NET¡Hola Un gusto saludarte En este articulo tutorial aprenderemos paso a paso a generar un modelo de Machine Learning personalizado desde ML NET para el análisis de sentimientos en texto y luego aprender a consumir ese modelo desde una aplicación web sobre ASP NET con el patrón MVVM Modelo Vista VistaModelo ¿Quées ML NET y cómo funciona ML NET es una plataforma de Machine Learning open source que nos permite transformar datos de entrada en un modelo ML para luego poder integrarlo en cualquier tipo de aplicación sobre el ecosistema de NET ya sean aplicaciones web móviles de escritorio o cualquier otro tipo de aplicación Estos son los tipos de modelos que podemos generar en ML NET Tipo de modeloObjetivoClasificación CategorizaciónDividir automáticamente los comentarios de los clientes en categorías positivas y negativas Regresión Predicción de valores continuosPredecir el precio de las casas en función del tamaño y la ubicación Detección de anomalías Detectar transacciones bancarias fraudulentas RecomendacionesSugerir productos que los compradores en línea quieran comprar en función de sus compras anteriores Series temporales datos secuencialesPronosticar el clima ventas Clasificación de imágenesCategorizar patologías en imágenes médicas En nuestro caso nos enfocaremos en la clasificación categorización de comentarios de texto Análisis de sentimientos en textoPara el análisis de sentimientos la intención es poder clasificar entradas de texto en dos grupos comentarios positivos y comentarios negativos Para lograr este objetivo realizaremos tres actividades en este articulo Cumplir con los requisitos necesarios y preparar nuestra solución en Visual Studio Crear nuestro modelo de Machine Learning con ML NET Consumir el modelo generado desde ASP NET Con esto mencionado ¡comencemos Parte Requisitos previos y preparación de la solución en Visual StudioPara poder generar nuestro modelo de Machine Learning utilizaremos el intérprete Model Builder de ML NET Para esto es necesario que contemos con la siguiente carga de trabajo en Visual Studio Desarrollo multiplataforma de NET Con esta carga de trabajo ahora podemos crear nuestra solución En este caso la intención es consumir el modelo ML que vayamos a generar desde una aplicación web para este propósito utilizaremos el framework DotVVM que nos permite trabajar con páginas HTML y clases C sobre ASP NET con el patrón MVVM Modelo Vista VistaModelo Parte Construcción del modelo de Machine Learning¡Llegóel momento de ver a ML NET en acción Como en cualquier otro proceso en el mundo del Machine Learning para generar un modelo los pasos para construir el modelo de análisis sentimientos son los siguientes Establecer el escenario ML Preparar el entorno para el entrenamiento de los datos Cargar el dataset Entrenar el modelo Evaluar el modelo Consumir el modelo Para empezar en el proyecto principal de nuestra solución agregaremos un componente de tipo Machine Learning Con esta opción el interprete de ML NET Model Builder se inicializaráy podremos comenzar a personalizar el modelo Escenario El primer paso es seleccionar el escenario con el que deseamos trabajar en este caso seráText classification Ambiente Ahora debemos seleccionar los recursos de cómputo para el entrenamiento de nuestro modelo Para la clasificación de texto en particular solo podemos utilizar la CPU de nuestra computadora Fuente de datos Esta es una de las partes más importantes ya que con los datos podremos personalizar nuestro modelo Para ello podemos seleccionar dos tipos de fuentes ya sea realizando una conexión y a la vez una consulta hacia una base de datos SQL Server o por medio de un archivo CSV En este caso utilizaremos un archivo CSV con dos columnas la primera con el texto en cuestión y la segunda columna con el tipo de comentario negativo positivo Este es un ejemplo de dataset wikipedia detox line data tsv Al cargarlo podremos tener una previsualización de los datos y seleccionar la columna que queremos predecir posteriormente Entrenamiento Con todo lo que ya hemos establecido hasta este momento ya podemos realizar el proceso de entrenamiento y generar finalmente el modelo deseado En esta sección lo único que podemos personalizar es el tiempo máximo en el que ML NET puede buscar el modelo ideal para la clasificación de texto Al finalizar el proceso de entrenamiento podemos visualizar cuantos modelos evaluóML NET y la exactitud del mejor modelo encontrado Evaluación Hasta este punto ya tenemos el modelo establecido de todas maneras desde el Model Builder de ML NET podemos evaluar el modelo con un ejemplo en particular Consumir Finalmente el intérprete nos brindaráopciones para consumir el modelo creado ya sea creando otros proyectos por consola o con una web api o indicándonos las llamadas que debemos hacer desde nuestra propia aplicación En este caso ya podemos consumir el modelo desde nuestra aplicación web con DotVVM sobre ASP NET con el nuevo paquete generado MLModel mbconfig Parte Consumir el modelo generado desde ASP NETPara consumir el modelo debemos hacer referencia a la clase MLModel la cual fue generada por ML NET en el grupo MLModel mbconfig En este sentido es necesario establecer una instancia de ModelInput con el comentario que queremos predecir para luego llamar al método Predict y obtener un objeto de tipo ModelOutput con la predicción correspondiente positivo negativo y su probabilidad ViewModel Para este propósito y para poder establecer una página web con DotVVM en un ViewModel en este caso el DefaultViewModel cs definiremos tres atributos o variables globales public string InputText get set public string Result get set null public decimal Score get set null Estas variables nos permitirán almacenar el texto ingresado por el usuario en InputText y representar los resultados de la predicción en los atributos Result y Score Luego podemos establecer un método en esta clase de tal manera que represente la acción de un botón para realizar la predicción public void Predict var sampleData new MLModel ModelInput Col InputText Load model and predict output var output MLModel Predict sampleData if int output Prediction Result Negative else Result Positive Score decimal Round decimal output Score int output Prediction En este código tenemos tres partes importantes Inicializar un MLModel ModelInput con el comentario ingresado por parte del usuario Llamar al MLModel Predict con el ModelInput como parámetro obteniendo asíel ModelOutput con los resultados Preparar el Result para visualizar el resultado posteriormente positivo o negativo y su exactitud en la predicción View Muy bien ahora podemos construir la vista al hacer referencia a los atributos y al método creado en el ViewModel Esta vista la codificaremos en el archivo Default dothtml de la siguiente manera lt table style border hidden gt lt tbody style border hidden gt lt tr style border hidden gt lt td style border hidden align center gt lt dot TextBox Text value InputText placeholder Write your text gt lt td gt lt td style border hidden align center gt lt dot Button Click command Predict Text Predict gt lt td gt lt td style border hidden align center gt lt b gt value Result lt b gt value Score lt td gt lt tr gt lt tbody gt lt table gt Aquílo más importante es el control TextBox para que el usuario ingrese su comentario y se almacene en el atributo InputText la llamada al método Predict con un Button y la visualización de los resultados al mostrar los valores de las variables Result y Score Ejemplos en ejecución Con esta View y su ViewModel nuestra página web se encuentra lista Aquípodemos ver dos ejemplos en tiempo de ejecución El código fuente del ejemplo mostrado se puede encontrar en el siguiente repositorio github com esdanielgomez MLNET SentimentAnalysis ¡Gracias Muchas gracias por leer espero que este demo pueda serte de utilidad Si tienes alguna pregunta o alguna idea que necesites discutir seráun gusto poder colaborarte y juntos intercambiar conocimientos entre sí ¡Nos vemos en Twitter O si gustas también puedes escribirme por

海外TECH	Engadget	Facebook says it doesn’t want to own the metaverse, just jumpstart it	https://www.engadget.com/facebook-connect-metaverse-zuckerberg-171507437.html?src=rss	Facebook says it doesn t want to own the metaverse just jumpstart itHere s what Facebook s metaverse isn t It s not an alternative world to help us escape from our dystopian reality a la Snow Crash It won t require VR or AR glasses at least not at first And most importantly it s not something Facebook wants to keep to itself Instead as Mark Zuckerberg described to media ahead of today s Facebook Connect conference the company is betting it ll be the next major computing platform after the rise of smartphones and the mobile web After spending the last decade becoming obsessed with our phones and tablets ーlearning to stare down and scroll practically as a reflex ーthe Facebook founder thinks we ll be spending more time looking up at the D objects floating around us in the digital realm Or maybe you ll be following a friend s avatar as they wander around your living room as a hologram It s basically a digital world layered right on top of the real world or an quot embodied internet quot as Zuckerberg describes Before he got into the weeds for his grand new vision though Zuckerberg also preempted criticism about looking into the future now as the Facebook Papers paint the company as a mismanaged behemoth that constantly prioritizes profit over safety While acknowledging the seriousness of the issues the company is facing noting that it ll continue to focus on solving them with quot industry leading quot investments Zuckerberg said nbsp Devindra Hardawar Engadget quot The reality is is that there s always going to be issues and for some people they may have the view that there s never really a great time to focus on the future From my perspective I think that we re here to create things and we believe that we can do this and that technology can make things better So we think it s important to to push forward quot Given the extent to which Facebook and Zuckerberg in particular have proven to be untrustworthy stewards of social technology it s almost laughable that the company wants us to buy into its future But like the rise of photo sharing and group chat apps Zuckerberg at least has a good sense of what s coming next And for all of his talk of turning Facebook into a metaverse company he s adamant that he doesn t want to build a metaverse that s entirely owned by Facebook He doesn t think other companies will either Like the mobile web he thinks every major technology company will contribute something towards the metaverse He s just hoping to make Facebook a pioneer quot Instead of looking at a screen or today how we look at the Internet I think in the future you re going to be in the experiences and I think that s just a qualitatively different experience quot Zuckerberg said It s not quite virtual reality as we think of it and it s not just augmented reality But ultimately he sees the metaverse as something that ll help to deliver more presence for digital social experiences ーthe sense of being there instead of just being trapped in a zoom window And he expects there to be continuity across devices so you ll be able to start chatting with friends on your phone and seamlessly join them as a hologram when you slip on AR glasses A simulated preview of Horizon Home FacebookBut of course the metaverse won t be built in a day At Facebook Connect today the company announced several ways it s moving towards making it more accessible For one Facebook will be transforming the Oculus Quest s Home interface into quot Horizon Home quot a more fully featured environment where you can invite friends and hang out virtually Eventually you ll also be able to build and customize your home space The Venues app is also becoming quot Horizon Venues quot where it ll continue to serve as Facebook s prime spot for live virtual events The company also says NBA games are coming back to Venues in early November The company is also making a major push for developers its new Presence Platform offers through APIs that ll allow devs to make more inventive VR apps The Insight SDK will let them take advantage of the Quest s cameras to bring the real world into VR the Interaction SDK opens up the door for more hand tracking interactions and the Voice SDK will ーyou guessed it ーlet you use your words in more ways The Insight SDK in particular could reshape what Quest VR experiences could look like It includes Spatial Anchors which will let virtual objects persist across sessions in a space So if you placed a VR pet bunny on your coffee table it should always be there every time you logged into an app Additionally there s a Scene Understanding feature which can help developers get a better sense of your physical space A character talking to you in VR could for example wander around your living room without bumping into furniture FacebookWhen it comes to augmented reality Facebook also has plenty of upgrades in store for its Spark AR platform For one it s planning to launch an iOS app called Polar that ll let people design their own AR effects and objects without any coding It s aimed at creators who could use it to build unique D signage or makeup effects that their followers can apply More experienced devs will also be able to create Geo anchored objects which are tied to specific locations in the real world as well as AR effects that track your hands and body They can also try out building group video chats for Messenger something that ll eventually be supported in other apps nbsp nbsp Like HoloLens and HTC Vive Facebook plans to make a bigger push into enterprises with Quest for Business It s a way for employees to log into Quest headsets with secure work accounts it s probably not great for your boss to see how often you re playing Beat Saber after all Since they re meant for office environments IT departments will also be able to manage work accounts specific devices and integrate their own security features The key is that it s all going to be accessible on consumer grade Quest headsets Facebook won t have to make entirely new hardware for work environments The company plans to take it slow with Quest for Business It s currently being tested with a few companies now and a wider beta is expected to come next year At this point Facebook isn t planning to officially roll it out to every company until Quest for Business will replace the previous Oculus for Business program which required a special Quest headset Facebook already showed off one way remote meetings could be handled better with Horizon Workrooms and that app is going to get better later this year with customizable workrooms And when it comes to productivity the company is also opening up the Oculus Store to D apps like Slack Dropbox Instagram and Facebook You ll be able to dive into those apps right from your Horizon Home screen It s convenient but it s also a cheeky way to keep you from taking off your headset just to answer a Slack message Not everyone would want to spend a whole workday wearing a VR headset but it s not hard to imagine how future AR glasses could let you dive into Slack and Office apps just about anywhere They ll just be D projections floating around you things that nobody else would be able to see That may seem like science fiction today but years ago so did the idea of having a touchscreen enabled supercomputer in your pocket with blazing fast wireless internet nbsp As Zuckerberg sees it the metaverse will ultimately lead to a more natural relationship with technology while of course giving us another way to buy digital goods quot It s not about you spending more time on screens quot he told press before making a hasty retreat quot It s about making the time we spend better and I think you know screens can t really convey the full sense of presence quot	2021-10-28 17:15:07
