Extended Reality (XR) encapsulates Augmented Reality (AR), Virtual Reality (VR), mixed reality (MR), and everything in between. Previously in XR, users have only been able to look in the X/Y/Z axes yielding three degrees of freedom (3DoF). This was great for stationary 360-degree video experiences, but underwhelming when it came to total immersion. Unlocking movement on the X/Y/Z axes, in addition to looking in the X/Y/Z axes, gives developers a total of six degrees of freedom (6Dof) and a much more immersive user experience.
Now that users can operate in 6DoF they want to move around more, but the current tethered VR solutions can hinder that ability. The Qualcomm® Snapdragon™ 835 VR Development Kit is designed to support 6DoF in a standalone mobile solution. It does this by harnessing the power of the Qualcomm Adreno™ 540 GPU and the Qualcomm Hexagon™ DSP. The Adreno 540 GPU offers Open GL ES 3.2 and DirectX 12 support in a 10nm package, and the Hexagon DSP is dedicated to offloading the 6DoF calculations from the GPU while sampling at 800Hz. All of this power packed into a head mounted device (HMD) unlocks the potential for truly immersive experiences.
The Ins and Outs of Tracking
To create 6DoF the Snapdragon VR Dev Kit combines two monochromatic (1280 x 800) global shutter cameras and an inertial measurement unit with fast interface Snapdragon 835 integrated sensor core. It then uses the DSP Sensor Fusion that is built into the SDK to combine camera images along with high frequency positional data as well as high frequency inertial data from gyroscopes and accelerometers to provide the final tracking data.
