Trigger control method and trigger control device for man-machine interactive operation

Abstract

Disclosed are a trigger and control method and device for a human-computer interaction operation. The method comprises: acquiring an image pick-up picture shot by an image pick-up device, and displaying the image pick-up picture on a display screen in a blurring manner; detecting a frame difference of the image pick-up picture, recognizing a designated contour on the image pick-up picture according to the frame difference, and calculating the location of the recognized designated contour on the display screen; and judging in real time whether the location of the designated contour on the display screen intersects a designated area displayed on the display screen or not, and if so, triggering an operation corresponding to the designated area.

Description

technical field [0001] The present application relates to the technical field of computer human-computer interaction, and in particular to a trigger control method and device for human-computer interaction operation. Background technique [0002] Human-computer interaction technology (Human-Computer Interaction Techniques) refers to the technology that realizes the dialogue between human and computer in an effective way through computer input and output devices. This technology includes: the machine provides a large amount of relevant information and prompts for instructions through output or display devices, and the human inputs relevant information, prompts, and operating instructions to the machine through the input device, and the human inputs relevant information to the machine through the input device to answer questions. Wait. Human-computer interaction technology is one of the important contents in computer user interface design. [0003] In the current human-compu...

Problems solved by technology

[0004] Although the above-mentioned human-computer interaction method has been widely accepted at present, for the handicapped persons with disabilities, the existing technology of using hands to input information and instructions to the computer is obviously not suitable, and cannot realize the human-computer interaction

Although there are also technical solutions for non-contact human-computer interaction input directly using gestures and hand shapes, this technical solution still needs to use hands to make corresponding actions, which is still inconvenient for the disabled.
