System for projecting content to a display surface having user-controlled size, shape and location/direction and apparatus and methods useful in conjunction therewith

摘要

A system having a finger-wearable sleeve having an IR light-emitting diode (LED), an IR camera; and a controller associated with the IR camera. The controller is configured to communicate with a host computer that utilizes a visual content projector to project visual content onto the screen. And based on signals received from the IR camera (1) trigger a first input functionality in the host computer, wherein the first input functionality is based on a location on the screen where an IR beam from the IR laser impinges, and (2) trigger a second input functionality in the host computer, wherein the second input functionality is based on a location on the screen near where an IR beam from the IR LED is emitted.

1. A system comprising:
at least two finger-wearable devices, each comprising:
a sensor configured to sense at least a pinching of thumb to finger,a light source, anda controller configured to encode two or more commands in light emitted by said light source, wherein at least one of the commands is responsive to the sensor sensing the pinching; a camera; a screen; and a computer associated with said camera and said screen, wherein said computer is configured to:
cause said screen to display visual content,detect, using said camera:
the light emitted by said light sources of said at least two finger-wearable devices, anda location from which said light sources emit the light,trigger different input functionalities in said computer based on:
the two or more commands encoded in the light emitted by said light sources, andthe detected location from which said light sources emit the light.
