Imagine your home transforming into a canvas for your next great painting. You can choose any brush, any color, and paint on any wall. Thankfully, the graffiti on your ceiling is digital— all within the realm of extended reality (XR).
Seamless blending of digital and real-world elements.
But why are depth sensors necessary in VR headsets?
Their importance lies in the ability to enhance a wide range of immersive and augmented experiences:
Time of flight and structured light sensors.
Time of flight (ToF) and structured light are two prevalent types of sensors.
A ToF depth sensor includes an emitter to project light, typically infrared, and a receiver to capture light reflections. The sensor calculates distances by measuring the time it takes for the light to travel from the emitter to the reflection point and back (known as the time of flight). ToF excels in long-range performance but offers less detail accuracy than structured light sensors and thus, these sensors are commonly used for environment mapping, AR, and person and object detection.
A structured light sensor projects a light pattern, consisting of thousands of infrared dots, onto the environment. The sensor then detects and reads the dots to build a depth map since dots that are closer will appear larger and dots that are farther will appear smaller. Structured light sensors are widely adopted in generating detailed depth profiles at close range, which are suitable for facial expression recognition and room-scale scanning.

In the latest firmware update for VIVE XR Elite , the structured light depth sensor located at the front of the standalone headset is now enabled.
Some nascent advantages are enhanced accuracy and speed of 3D environment scanning and the generation of 3D meshes, which developers can utilize in the applications and experiences they are creating.

Incorporating depth sensors into VR headsets is pivotal in elevating the overall realism of computer-generated experiences. Accurate environment scanning and quick 3D mesh generation are just a few potential benefits, enabling the creation of lifelike digital representations and seamless integration of virtual objects into the real world.
As VR and AR technologies evolve, depth sensors will become increasingly indispensable, propelling advancements in immersive and augmented experiences and redefining the way the physical and digital interact.
