Twilio has released its new DataTracks API, which allows developers to build shared AR experiences using Twilio Video. The example app, "DesignConsult," demonstrates how designers and clients can communicate about furniture placement in 3D space using audio, video, and data tracks. The app uses ARKit and Twilio's new DataTracks API to send messages between the designer and client, who can then use these messages to place objects in their virtual environment. The client can also see the designer's actions in real-time through a shared video feed, while the designer can communicate with the client using audio tracks. The app showcases the potential of Twilio's new DataTracks API for building powerful, interactive AR experiences.
