Two-dimensional cursor control method and device

Abstract

The invention discloses a two-dimensional cursor control method and device, and the method comprises the steps: inputting a first extraction result and a second extraction result into a preset classification model for classification, and obtaining corresponding classification results; performing regression prediction on the classification result according to a Gaussian process regression model, and predicting a target position of the two-dimensional cursor; and controlling the two-dimensional cursor to move to the target position. Therefore, the embodiment of the invention is adopted; a firstextraction result corresponding to an eye movement signal and a second extraction result corresponding to an electroencephalogram signal are input into a preset classification model for classificationprocessing to obtain the corresponding classification result, regression prediction is carried out on the classification result according to the Gaussian process regression model, the target positionof the two-dimensional cursor can be accurately predicted, and the two-dimensional cursor is controlled to move to the predicted target position.

Description

technical field [0001] The invention combines eye-tracking technology, virtual reality technology and brain-computer interface technology, relates to the fields of image processing and signal encoding / decoding, and particularly relates to a two-dimensional cursor control method and device. Background technique [0002] The eye is an important organ for humans to obtain information from the surrounding world. 80% of the external information received by people comes from the visual channel established by the eyes. At the same time, when people are carrying out thinking or psychological activities, their activity process will be reflected in the eye movement behavior. Eye tracking technology refers to the tracking of eye movement by measuring the gaze point of the eye or the movement of the eye relative to the head. When people's eyes look in different directions, there will be subtle changes in the eyes, and these changes will produce features that can be extracted. The compu...

Problems solved by technology

[0004] Since the interactive capability of VR relies on the development of stereoscopic display and sensor technology, the existing mechanical and tactile sensing devices are not mature enough, which leads to the need to improve the tracking accuracy and tracking range of VR equipment.
