Abstract
An electronic device receives inputs using images of input devices and scanning sensors that detect user interaction with those images. For example, an image of a mouse may be projected and the user's interaction with that image may be scanned using digital video cameras. These user movement images may then be analyzed to determine, for example, the direction, extent and rate of movement of the user to provide pointer position command signals. Similarly the user's movement relative to a virtual keyboard image may be analyzed and converted into key actuation signals for responding to the actuated virtual keys.
Claims9
A method for inputting data to an electronic device comprising:
- projecting an image of a mouse on a surface;
- and
- detecting user movements relative to said mouse image.
article comprising a medium for storing instructions that, if executed, enable a computer to:
- project an image of a mouse on a surface;
- and
- detect user movements relative to said image.
A system comprising:
- a processor;
- a sensor coupled to said processor;
- a projector coupled to said processor;
- and
- a memory associated with said processor, said memory storing a computer program that enables a processor to project an image of a mouse using said projector and use said sensor to detect user movement relative to said image of said mouse.
