| Abstract: |
A computer input system and method is described which includes a spatial reference member having a body with a first surface and an opposing second surface. The spatial reference member separates a first spatial region including the first surface from a second spatial region including the second surface. A physical object is movable within the first spatial region. Optical indicia tracks the physical object through the body. The optical indicia is observable from the second spatial region. An optical detector positioned in the second spatial region tracks the optical indicia and develops signals which may serve as inputs to a computer. The object may emit a signal which is tracked by the optical detector.

First Claim:
Show all 15 claims |
What is claimed is:
1. A computer input system comprising:
- a support frame configurable to engage with a plurality of spatial reference members, each spatial reference member being configurable to engage with the support frame such that the spatial reference members are interchangeable with each other, wherein a first one of the spatial reference members is associated with a different application than a second one of the spatial reference members;
- a first physical object movable within a first spatial region associated with the first spatial reference member when it is engaged with the support frame;
- indicia associated with a position of the first physical object; and
- a detector arranged to detect the indicia associated with the position of the first physical object and to generate signals for inputting into an application of a computer, the application being related to which spatial reference member is engaged with the support frame.
