Oculus Quest 2 (Meta Quest 2) has 6 GB of RAM combined with the ultra-fast Qualcomm Snapdragon XR2 platform. It consists of a projection helmet and two controllers. The helmet houses two screens for the eyes with the ability to adjust focus and the addition of an eyeglass attachment. A fast switchable LCD display with low backlight persistence, 1832 × 1920 pixels per eye resolution, will allow visual fidelity of approximately 21 PPD (pixels per degree) without blurring or doubling artefacts. Adjustable straps are used to secure the helmet to the head. Both the right- and left-touch controllers have multiple control buttons, a joystick, and an adjustable fixation strap that attaches to the wrist to prevent the controller from potentially falling out of the hand. With built-in Bluetooth and an app on a mobile phone or tablet, the therapist can monitor what the patient sees and how effectively they perform each task.
