Abstract

The invention provides a cursor positioning method and device and a cursor control method and device. The method comprises the steps that S1, a displayer is equally divided into sub-regions in a preset quantity, and all the sub-regions flicker at different frequencies; S2, an electroencephalogram signal sent by an electroencephalogram collection processing device is received, wherein the brain electric signal is obtained after the brain electric collection processing device collects the brain electric signal of a user watching the displayer; S3, the brain electric signal is processed and analyzed, and a first sub-region is determined from all the sub-regions to serve as a watching region of the user according to the processing and analysis result; and S4, the steps S1, S2 and S3 are repeated, the first sub-region is divided, and when the number of times of division is greater than a preset threshold value, the first sub-region is determined as a cursor clicking position. Through the embodiment, the control efficiency of a cursor is improved, the operation steps better conform to a natural selection reaction of the user, and natural interaction between the user and a computer can be realized.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a cursor positioning and cursor control method and device. Background technique [0002] There are three stages in the development of human-computer interaction, which are command line interface interaction stage, graphical user interface interaction stage and natural and harmonious human-computer interaction stage. In the interactive stage of the command line interface, the computer user is regarded as the operator. The computer generally responds passively to the input information, and the operator mainly inputs data and command information through the keyboard. Obviously, this human-computer interface interaction method lacks naturalness. sex. Graphical user interface interaction phase relies on menu selection and interactive components, but repetitive menu selection will cause inconvenience to users. The stage of natural and harmonious human-computer inte...
