Abstract
Methods, systems, and computer programs are presented for detecting inputs for a computing device. One method includes an operation for receiving images for an area where the hand of a user is situated, and an operation for analyzing the received images to determine the location and the color of a finger of the user. Further, a change in the color of the finger is detected, where the change in the color is caused by contact of the finger with a physical object. In other operation, the method determines the location of the finger when the color change was detected. The determined location is associated with an input for the computing device.
Claims25
A method for detecting an input for a computing device, the method comprising:
- receiving images for an area where a hand of a user is situated;
- analyzing the images to determine a location and color of a finger of the user;
- detecting a change in the color of the finger, the change in the color being caused by contact of the finger with a physical object;
- determining a location of the finger when the change was detected;
- and
- associating the determined location with an input for the computing device.
A method for detecting an input for a computing device, the method comprising:
- analyzing images for an area in front of a display where a user is situated to determine a location of eyes and a finger of the user;
- detecting a change in a color of the finger when the finger is pressed against a transparent surface situated between an eye of the user and the display;
- determining a location of the finger and a location of the eye when the change was detected;
- determining an object on the display associated with an intersection of the display with a line joining the location of the eye with the display through the location of the finger;
- and
- performing an operation by a computer program based on the determined object.
A method for detecting an input for a computing device, the method comprising:
- receiving images for an area where a hand of a user is situated;
- analyzing the images to determine a location and color of a finger of the user;
- detecting a first change in the color of the finger, the change in the color being caused by contact of the finger with a physical object;
- determining a location of the finger when the change was detected;
- tracking a motion of the finger until a second change in the color of the finger is detected, the second change being caused by lack of contact of the finger with the physical object;
- and
- associating the determined location and the tracked motion with an input for the computing device.
