Z-AXIS DETERMINATION IN A 2D GESTURE SYSTEM |
| 摘要 |
Systems, apparatus and methods for determining a gesture are presented. According to some aspects, disclosed are systems, apparatus and methods for determining a gesture that compares different images and deduces a direction and/or distance based on a relative size change of a palm in the different images. After a reference palm size is registered, subsequent palm sizes are compared to the reference to determine if and/or how much the hand is moving. The hand gesture is determined based on these relative changes in hand movement. |

1. A method in a mobile device for determining a gesture, the method comprising:
capturing a first image containing a hand having a first size; computing a first indication of the first size of the hand in the first image; capturing a second image containing the hand having a second size; computing a second indication of the second size of the hand in the second image; computing a relative change between the first image and the second image; and determining the gesture based on the relative change. |
