example 1

[0142] Example 1, assuming that the object of interactive control is a game machine running a role-playing (RPG) game, and using symbol recognition to generate control instructions, see Figure 4a , when the trajectory of the fingertip is a straight line from right to left, the corresponding control command means to control the character in the game to move to the left; when the track of the fingertip is a straight line from left to right, the corresponding control command means to control the game The character in the game moves to the right; when the trajectory of the fingertip is a counterclockwise semicircle from top to bottom, the control instruction means to control the character in the game to turn from the left; when the trajectory of the fingertip is a half clockwise arc from top to bottom arc, the control command means to control the character in the game to turn from the right side;

example 2

[0143] Example 2, assuming an interactively controlled target TV, and using symbol recognition to generate control commands, see Figure 4b , when the trajectory of the fingertip is a straight line from right to left, the corresponding control command indicates that the channel number is reduced by one; when the track of the fingertip is a straight line from left to right, the corresponding control command indicates that the channel number is increased by one; If the trajectory of the fingertip is a straight line from top to bottom, then the control command means to decrease the volume by one; when the track of the fingertip is a straight line from bottom to top, the control command means to increase the volume by one.

[0144] In addition to the above two examples, the trajectory of the fingertips can also draw numbers, letters, and character shapes, and the text recognition technology can be used to realize interactive control. The specific examples will not be listed one by ...

Abstract

The invention discloses a method and a device for acquiring the track of a hand fingertip, an acquired control method and an acquired control system based on the track of the hand fingertip. The invention can acquire the positions of the hand fingertip in a plurality of consecutive images and connect the positions of the hand fingertip in each images to a track, so that the corresponding control command of the track of the hand fingertip is generated according to the presupposed corresponding relation between the track of the hand fingertip and the control command, thereby achieving the interactive control without additional input devices.

Description

technical field [0001] The invention relates to pattern recognition technology, in particular to a fingertip trajectory acquisition method, a fingertip trajectory acquisition device, a fingertip trajectory-based control method, and a fingertip trajectory-based control system. Background technique [0002] In the prior art, for interactive control processes such as game operations and TV channel switching, it is usually necessary to use additional input devices such as gamepads, mice, keyboards, and remote controls. However, various interactive controls are limited due to the inconvenience of carrying various additional input devices. Contents of the invention [0003] In view of this, the present invention provides a fingertip trajectory acquisition method and a fingertip trajectory acquisition device, which can support control without an input device. [0004] The invention also provides a control method based on fingertip trajectory and a control system based on fingert...
