GESTURE BASED USER INTERFACE
First Claim
1. A portable computing device including a camera configured to capture one or more images, a memory and a central processing unit, the central processing unit configured to analyze the image and detect and identify a hand gesture of a user in the image, the central processing unit comprising computer readable code means, which when executed on the central processing unit are configured to:
- determine that the captured image includes a predefined activation gesture;
detect a second gesture in the captured image;
identify a command corresponding to the second gesture; and
executing the command to perform a function in the portable computing device corresponding to the command.

Abstract
A system and method for recognition of hand gesture in computing devices. The system recognizes a hand of a user by identifying a predefined first gesture and further collects visual information related to the hand identified on the basis of the first predefined gesture. The visual information is used to extract a second gesture (and all other gestures after the second) from the video/image captured by the camera and finally interpreting the second gesture as a user input to the computing device. The system enables gesture recognition in various light conditions and can be operated by various user hands including the ones wearing gloves.

16. A method of interpreting a hand gesture in an image captured by an image capturing device communicatively coupled to a computing device, comprising using a processor of the computing device to:
-
detect a first hand gesture in the captured image; determine that the first hand gesture corresponds to an activation gesture; detect a subsequent hand gesture in the captured image; identify a command corresponding to the subsequent hand gesture, the command being configured to execute an action in the computing device when the command is triggered; and execute the command in the computing device. - View Dependent Claims (17, 18, 19, 20)
