As with its PS5 in 2020, Sony is tearing down its PSVR 2 and its two controllers in front of the cameras. The perfect opportunity to discover some design secrets of the helmet.
How does the PlayStation VR 2 manage to precisely track its two controllers without external sensors? Well now we know. Sony has shared two teardown videos of its virtual reality headset and accompanying controllers on YouTube. In front of the cameras, two engineers from the group disassemble everything that can be disassembled, to reveal the internal design details of the PS5 peripheral and its two accessories.
We then discover that if the PSVR 2 can follow its Sense controllers without outside help, it is thanks to a series of 14 infrared LEDs hidden directly in the controllers, at the level of their “orbit”, and under a white cover that can be removed in a few screw turns. In detail, a flexible plastic headband brings together these IR diodes, staggered to allow precise detection by the helmet cameras.
When Sony (meticulously) tears the PSVR and its controllers to pieces
” These infrared lights are used by the VR headset’s tracking camera to detect the position and orientation of the controller “comments Takeshi Igarashi (engineer also behind the PS5 DualSense controllers) soberly when dismantling the controllers. ” These LEDs have been placed in optimal locations to ensure accurate detection no matter which direction the controller is pointing “, he adds, before specifying that the hull of the controllers is also made of a material having the property of “ transmit internally emitted infrared light “.

For the rest, and as pointed out The Verge, the disassembly video of the controllers allows us to have an overview of the touch sensors of the two controllers, but also to discover the hidden face of their hiding places. High-precision mechanics at the service of the video game experience.

The teardown video of the helmet itself also reveals its share of internal design details. Onin learns in particular how Sony manages to follow the gaze of the user. To do this, the firm also relies on infrared LEDs: one at each lens. An infrared camera housed inside the helmet then detects the light emitted by these LEDs so as to follow eye movements. Simple and unstoppable.
As a reminder, the PSVR 2 will arrive on the market on February 22 at a starting price (higher than that of the PS5) that we mentioned right here.
