Abstract
A gesture control method includes receiving first gesture control data. The gesture control method includes converting the first gesture control data into second gesture control data of a standard coordinate system. The gesture control method includes controlling the display screen according to the second gesture control data.
Claims12
A gesture control method for a display screen, comprising:
- receiving first gesture control data, the first gesture control data being collected and uploaded by one of a plurality of gesture detection modules disposed on a display screen, and detection ranges of the plurality of gesture detection modules covering various directions of the display screen;
- converting the first gesture control data into second gesture control data of a standard coordinate system, the standard coordinate system being a coordinate system taking a center of a preset standard gesture detection module as an origin;
- controlling the display screen according to the second gesture control data;
- and
- before receiving first gesture control data:
- obtaining gesture control data respectively corresponding to an (N−1)th gesture detection module and an Nth gesture detection module in a same group of control actions, which are the first gesture control data and the second gesture control data, respectively;
- and
- calculating a transformation matrix and a translation matrix between the (N−1)th gesture detection module and the Nth gesture detection module according to the first gesture control data and the second gesture control data, the transformation matrix and the translation matrix being configured to transform the first gesture control data and the second gesture control data.
