Introducing the view model
Understanding physical to virtual mappings
- Physical device configurations and a room-mounted view policy
establish:
- Mappings from eye to head, to head tracker, to tracker
base, to image plate (portal screen)
- A tracker base to coexistence transform maps from the
tracker base to the portal center
- Or whatever reference point you prefer
- As the user moves about, their location is computable relative
to this coexistence frame of reference - the portal center
