Techniques
ir lighting and lenses
- need to keep lighting on stage low
- point grey sells 120fps cams
- flood stage with IR light then look for silhouettes
Motion Trackers
- can do realtime
- typically incorporated with SteamVR
- Unity seems to have support
- need minimum of 3 (L leg, R leg, hip) but can have more
Brands
- Vive
- the standard
- v3.0 has 8 hour battery life.
- fairly bulky
- can increase range by using up to 4 base stations (lighthouses) although has been tested with 16
- Tundra
- 1/2 the weight and size as Vive
- has developer kit
-
- this looks fantastic but it is in preorder and they aren't shipping until March 2024.
- range is Wi-Fi range
- they have a nice comparison chart
-
- sensors you wear
- BT range
- < $500
-
- similar to Haritorax?
- uses BT.
- 6 trackers you wear. < $500
- works with Unity
- might only connect with phone?
-
- full suit starts at $2K
- add sensors to shoes
-
- this looks like a $5K investment
- targetting industry
-
- this appears to be a software-only solution and still requires motion trackers?
Interfacing
