Meta Quest 2 VR, the Most Interesting Computer I Own

Years ago, I mounted a Samsung Galaxy Note 2 into a Google Cardboard, producing a limited early example of a VR, later got a more polished plastic headset to hold a Galaxy Note 3 that Alicia gave me, that still works, and this was more polished as a VR kit, but still very early. 

Some friends and coworkers went the way of building gaming desktops to high end VR headset systems, but that did not appeal to me, I wanted the standalone wearable kind, but something dope.

I was on Amazon one night researching workouts on Wikipedia and stumbled upon VR Kickboxing via Beat Saber and Les Mills Body Combat, then looked up how to do it, Goggle AI summarized that a Meta Quest 2 VR system would match my need for exertainment.

 

Meta Quest 2 — Advanced All-In-One Virtual Reality Headset — 128 GB $298 paid

Via Microsoft Copilot, on the Computation architecture of Meta Quest 2

Meta Quest 2 powered by the Qualcomm Snapdragon XR2, a system on a chip (SOC) designed for VR and augmented reality devices. SOC derivative of the Snapdragon 865, optimized for low-latency sensor fusion, crucial for the headset's performance in virtual reality applications. 

Quest 2's architecture includes Visual Processing Unit (VPU) that handles processing of passthrough video, ensuring a motion-to-photon latency of below 20 milliseconds to prevent motion sickness. 

A depth Sensor projects a mesh of infrared light onto the room, allowing for creation of a 3D 'Environmental Mesh' essential for 'Occlusion', ability for a virtual character to hide behind a real-world object. 

Quest 2's architecture is designed to deliver a high-resolution display with a refresh rate of 120 Hz, providing an immersive and smooth VR experience. 

Qualcomm Snapdragon XR2 5G Platform is the world’s first XR platform to integrate 5G and AI for next‑generation virtual and augmented reality experiences Qualcomm.

7 concurrent cameras for precise motion tracking, gesture recognition, and 360° spherical video capture Qualcomm.

Mixed reality (MR) capability with 3D video pass‑through, allowing VR and AR to coexist in one device while maintaining situational awareness Qualcomm.

AI integration for personalized, predictive experiences with optimized power efficiency Qualcomm.

5G connectivity for ultra‑low latency, instant content loading, and global multiplayer interactions Qualcomm.

8K 360° video support for highly immersive, high‑fidelity visuals Qualcomm.

Rich 3D audio for spatial sound in all directions Qualcomm.

Tuning Quest 2 for VR Kickboxing

I got an upgraded head strap battery $80, the Quest 2 VR $300, silicon face interface $15, charged it up, put LR6 or AA batteries into each remote, spent an hour or so integrating my old disused Facebook account, to activate it, purchased Les Mills Body Combat app $40, then started doing VR kickboxing. 

I added creatine into added protein shakes to account for all the extra exertion, and despite keeping the same 32 in pant size, I was able to gain about 20 lbs of body weight as mostly muscle and bon. Today I have completed 214 VR kickboxing sessions, yet the right remote for Quest 2 vibrator motor cutting in an out, replacing the remote costs over $100, so I am almost ready to start over with a Quest 3 system and keep going.

If I attached a Bluetooth keyboard to Quest 2, I  could write blog posting on the Quest 2, and regularly watch big screen YouTube videos on it while laying down in bed resting, awake, but sore from VR kickboxing, after showering off & cleaning up of course, since those VR workouts make me very hot and sweaty, I get runners high, fantastic.
