Abstract

Embodiments of the present invention provide a recognition method and device based on a multi-touch screen, and an electronic device that detects a touch signal input by an object to be recognized to a multi-touch screen, and determines the touch signal according to a preset corresponding relationship. is the characteristic feature of the object, and then identify the object according to the characteristics of the object, because the basis for determining the characteristic feature is the preset corresponding relationship, therefore, it is not necessary to identify the contact point corresponding to the marker point, so , there is no limit to the size and spacing of the marker points, so the area and the spacing of the marker points can be reduced, which is suitable for the recognition of small-area objects.

Description

technical field [0001] The invention relates to the field of human-computer interaction, in particular to a recognition method and device based on a multi-touch screen, and electronic equipment. Background technique [0002] The multi-touch touch screen supports simultaneous input of multiple touch points. The touch screen based on multi-touch can realize the recognition of the object. The specific recognition method is: pre-set the mark points made of specific materials on the object, and the touch screen receives the mark points. After inputting the signal, firstly identify the contact point corresponding to the mark point on the screen, and use the spatial information between the contact points to characterize the object and distinguish different objects. For example, if marking points are set on chess pieces, the multi-touch touch screen can be used as a chessboard. [0003] Since the recognition of objects depends on the spatial information of the touch points sensed b...
