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.

Claims

1. 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.

2. The gesture input system according to claim 1, further comprising

template storage means for storing a template for recognizing a motion of a user, wherein

the input interface means includes:

template matching means for matching motion information converted by the preprocessing means against a template stored in the template storage means; and

event output means for outputting an output event associated with a template matched by the template matching means.

3. The gesture input system according to claim 2, wherein

the object includes a pie menu in which a menu item is disposed in a circular form, and a user selects any menu item in the pie menu by twisting a wrist thereof.

4. The gesture input system according to claim 3, wherein

the event output means sequentially selects a menu item in the pie menu in a direction in which a user twists a wrist thereof.

5. The gesture input system according to claim 4, wherein

the pie menu is layered.

6. 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.

7. A program for causing a computer to perform the gesture input method according to claim 6.
