This project allows you to track points in 3d invieroment using gyroscopes.
This gives you the ability you to track your body. Uses can be found in VR Gaming, AR interfaces, sport and physical tracking, Location estimation
Current State:
- Point localization algorithm
- API implementation
- Custom json file on configuration
- ESP-NOW Communication
- Controllers
- Movement algorithm
- Headset display

Limitations
1. Many sensors are needed to track every main point of the body.
2. Every point should have a "parent" point. (Except point zero)

Questions
How big is the GRVR PCB?
It measures 30.5 × 59.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GRVR use?
20 parts, built around the BC337. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the GRVR KiCad files?
From the eGuardianDev/GRVR repository on GitHub, at the commit this page was made from: the board is Design/Design.kicad_pcb and its schematic Design/Design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GRVR design in my own project?
Its repository states no licence, so its author keeps all rights: ask eGuardianDev before reusing the design.
