Abstract
The present invention provides an input interface that a human can operate naturally and intuitively using a human gesture (motion), by including means for acquiring motion information based on a gesture and input interface means for generating information for operating an object on a desktop of a computer on the basis of motion information. In this case, the motion information is matched against a template for recognizing a motion of a user and a matched event is outputted so that the object is operated. The object includes a pie menu in which a menu item is disposed in a circular form. A user is allowed to selects a desired menu item in the pie menu in accordance with an angle at which the user twists a wrist thereof.
Claims7
A gesture input system comprising:
- motion information acquisition means for acquiring motion information based on a gesture;
- preprocessing means for performing normalization and coordinate conversion on motion information acquired by the motion information acquisition means;
- and
- input interface means for generating information for operating an object on a desktop of a computer on the basis of motion information converted by the preprocessing means.
The gesture input method comprising:
- a motion information acquisition step of acquiring motion information based on a gesture;
- a preprocessing step of performing normalization and coordinate conversion on motion information acquired in the motion information acquisition step;
- and
- a step of generating information for operating an object on a desktop on the basis of motion information converted in the preprocessing step.
