Abstract
A system for interacting with a screen without touching it, comprising a source of radiating energy directed into a predefined area, at least one directionally sensitive sensor that detects the radiation when it's reflected off of an object within the predefined area, and a processor that calculates position and motion information of the object and generates therefrom image information, which it sends to a screen where it is displayed.
Claims14
A system for interacting with a screen without touching it, the system comprising:
- a source of laser energy directed into a predefined area;
- a motor that causes the source of laser energy to sweep through an angle to define a plane, wherein the laser energy is configured to cause a prominent dot to appear on an object where the object crosses the plane;
- at least one directionally sensitive sensor configured as a camera that is configured to:
- detect a direction to the dot and a motion of the dot;
- and
- send, to a computing processor, information of a location from which the laser energy is reflected;
- the computing processor that uses the location information to calculate a position and a motion of the object from which the laser energy was reflected, and generate image information based on the calculated position and motion, and send the image information to a screen for display;
- and
- the screen that displays an image based on the image information received from the computing processor.
