Gesture control device and method for displaying a large wall

Abstract

The invention discloses a gesture control device and method for displaying a large wall. The gesture instruction set is preset, and the trajectory of the speaker's finger movement is compared with the gesture graphics in the instruction set. If they match, the speaker is determined to issue a corresponding instruction, thereby responding It should be commanded to control the display screen showing the large wall. In actual implementation, the speaker only needs to wear a fingernail-sized collection device on his finger, without getting close to the large display wall or holding any equipment, thus freeing the speaker's hands and body to devote himself to the speech.

Description

technical field [0001] The present invention relates to the technical field of video wall display, in particular to a gesture control device and method for displaying a large wall. Background technique [0002] When people use large splicing walls or large-sized electronic whiteboards to make PPT presentations, the speaker needs to do some simple operations, such as turning pages of PPT, focusing on courseware, switching files, zooming images, and even switching signals on the display wall, etc. operate. [0003] Typically, people use desktop computers, notebooks, tablets, mobile phones, laser pointers, styluses, motion capture, and other devices to assist in completing operations. However, these devices have certain limitations, such as desktop computers and notebooks, the speaker needs to stand or sit next to the device to operate; such as tablet computers and mobile phones, the speaker must operate the device with one or two hands; such as laser Pen, the speaker must ho...

Problems solved by technology

However, the operation of these devices has certain limitations, such as desktop computers and notebooks, the speaker needs to stand or sit next to the device to operate; such as tablet computers and mobile phones, the speaker must hold the device with one hand or both hands to operate; such as laser Pen, the speaker must hold the device to operate; such as a stylus, the speaker must write on the electronic whiteboard

When the electronic whiteboard is higher than the speaker, the speaker cannot simply complete writing and other operations; such as motion capture equipment, the speaker has to raise his hand to start and operate, the controllable accuracy is poor, and the operation is inconvenient. There can't be anything in between

[0004] In general, these operating devices restrict the speaker's hands or body, weakening the speaker's body language

During operation, the speaker diverts attention to use the device, causing multiple short interruptions in the speech
