Abstract

The invention is suitable for the technical field of data processing, and provides a multi-point display method and device based on an intelligent blackboard and terminal equipment. The method comprises the steps that it is detected that multiple objects exist at the position away from the intelligent blackboard by a preset distance through a sensing device, and the position coordinates of each object in the multiple objects are determined; a processing unit determines the size of each object and the distance between any two objects based on the position coordinates; the processing unit determines one or more effective objects in the plurality of objects according to the size of each object and the distance between any two objects; the processing unit collects contact information of effective objects on the intelligent blackboard through the sensing device; and the processing unit sends the contact information to the display equipment, so that the display equipment displays the handwriting of the effective object on the intelligent blackboard based on the contact information. According to the invention, the requirements that multiple persons write at the same time and the writers are commented in sequence after writing are met, and the practical problems in teaching and conferences are solved.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a multi-point display method, device and terminal equipment based on an intelligent blackboard. Background technique [0002] The traditional blackboard can only be written with chalk, that is, it cannot be touch-interacted like an LCD whiteboard, nor can it transmit the blackboard writing content to the display device, let alone push it to the cloud for downloading and viewing by smart terminal devices. With the rapid development of science and technology, electronic teaching has become a trend of teaching, and electronic devices such as projectors, electronic whiteboards and smart blackboards have appeared. [0003] Among them, the smart blackboard uses chalk or water pen instead of electromagnetic pen and handwriting according to people's daily habits. At the same time, it has been proved that writing with chalk or water pen is the most flexible a...
