Patent Images
1. A method, comprising:
- recognizing with a camera a disturbance of a disturbing object in a display zone of a projected image;
making a determination as to whether a shape of the disturbing object is a valid shape in a template;
displaying a selected state of a selected item when the disturbing object is a valid shape;
recognizing with the camera a movement comprising a combination of two substantially simultaneous actions, including a first action of the disturbing object and a second action of an object in an interaction zone between the camera and the projected image;
validating the movement comprising the combination of the first action and the second action by comparing the first action and the second action to a plurality of predefined gestures; and
executing a command based on the validating of the combination of the first action and the second action.

Abstract
A system and method of interacting with a display. The method comprises recognizing a disturbance in a display zone of a projected image and displaying a selected state in response to the recognized disturbance. The method further includes recognizing a gesture which interrupts a light source and is associated with an action to be taken on or associated with the displayed selected state. An action is executed in response to the recognized gesture. The system includes a server having a database containing data associated with at least one or more predefined gestures, and at least one of a hardware and software component for executing an action based on the at least one or more predefined gestures.

9. A system comprising a server having a database containing data associated with at least one or more predefined gestures, and at least one of a hardware and software component for executing an action based on the at least one or more predefined gestures, the hardware and software:
-
comparing a first action of a disturbing object, detected by a camera, in an interaction zone between the camera and a projected image to a predefined template of a shape; recognizing a gesture detected by the camera, which interrupts a light source between the camera and the projected image, the gesture comprising a combination of two substantially simultaneous hand motions; determining that the gesture corresponds to a predefined command of the user interface; and executing the command corresponding to the gesture. - View Dependent Claims (10, 11, 12, 13)

14. A computer program product comprising a computer usable storage medium having readable program code embodied in the storage medium, the computer program product includes at least one component to:
-
recognize a disturbance caused by a first finger of a first hand of the user in a display zone of a user interface image projected on a surface in the field of vision of the camera; display a selected state in response to the recognized disturbance; recognize a gesture interrupting a light source and associated with an action to be taken on or associated with the displayed selected state, the gesture comprising a combination of two substantially simultaneous motions by the first hand of the user and a second hand of the user; determine that the gesture corresponds to a command of the user interface based on one or more look-up tables populated with a plurality of pre-defined hand motions and a respective plurality of commands of the user interface; and execute the associated command of the user interface in response to the gesture. - View Dependent Claims (15, 16, 17, 18)
