The compositing is a combination of light from real world and light presented on display to make them visible together to a user's eyes. SA WG4 has conducted studies on support for XR services (TR 26.928) in general and AR services (TR 26.998) in particular. As documented in TR 26.928 and TR 26.998, the knowledge of the real world is essential for the localization of the AR device and for a seamless insertion of virtual content into the user's real environment. The set of AR functions which process sensor data to generate information about the world 3D space surrounding the AR user are often collectively referred to as spatial computing. Spatial computing includes functions such as tracking (to estimate the movement of the AR device at a high frequency), relocalization (to estimate the pose of the AR device), mapping (to reconstruct the surrounding space), and semantic perception (to process the captured information into semantical concepts). The resulting output of spatial computing is a set of spatial mapping information that is organized in a data structure called the XR Spatial Description for storing and exchanging the information. {. . .}","secretary_remarks":"Revision of SP-240677.

In 2022, over 90% of cell phones and game consoles include haptic technologies. Haptic is used for two purposes, user feedback and as one of the media (audio\/visual\/haptic) in immersive or communication experiences. Today's communication over cell phones is transmitting speech and\/or video between UEs, or between UEs and application servers and applications. However, the cellphones have vibrotactile actuators built in. The information transmitted for using those actuators is generally proprietary. This is an interoperability issue when exchanging information between devices from different manufacturers or when these devices receive media services that include haptic experiences. With the emergence of XR devices, the presence of haptics media in an immersive XR experience plays a significant role in improving the sense of presence and immersion.
