Cursor control method of head-mounted device

Abstract

The invention provides a cursor control method of a head-mounted device. The method includes the following steps that a head motion processing sensor maps detected head motion data to be a head motion two-dimensional coordinate displacement and sends the head motion two-dimensional coordinate displacement to a microprocessor; meanwhile, an eye tracker maps detected eye motion data to be an eye motion two-dimensional coordinate displacement and sends the eye motion two-dimensional coordinate displacement to the microprocessor; the microprocessor superimposes the head motion two-dimensional coordinate displacement and the eye motion two-dimensional coordinate displacement to be a two-dimensional coordinate of cursor moving; a click event is executed through a voice recognition module, and the click event and the two-dimensional coordinate of the cursor moving are output together. The fact that the head and the eyes subconsciously move in a coordinated mode by nature is used, so that a mouse is controlled through sampling recognition achieved by head moving, eye moving and tooth touching, intelligent equipment can be put on the body of a person and carried, hands are freed, meanwhile the most direct and precise consciousness expression mode is achieved, namely what is seen can be controlled, operation is natural and easy, the action quantity is small, consumption of physical and mental energy in operation is reduced, time operation is facilitated, and the disabled can conveniently control the cursor.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a cursor control method of a head-mounted device. Background technique [0002] Cursor control methods of most mice, touchpads, head-moving mice, eye trackers, etc. in the prior art quantify one or one action output of the human body. [0003] Among them, the eye movement recognition in the prior art is to estimate the area of ​​the pupil's field of view, the accuracy and stability are very poor, and it does not have the conditions to replace the mouse. Moreover, there is no practical confirmation key function for eye movement recognition, and more importantly, the body posture compensation behavior that ignores ergonomics and visual psychological target errors, so users are awkward to use, and the cursor accuracy is not enough. Long-term forced use will cause body damage. [0004] Therefore, there are defects in the prior art and need to be further improved and d...

Moreover, there is no practical confirmation key function for eye movement recognition, and more importantly, it ignores the body posture compensation behavior of ergonomics and visual psychological target errors, so users are very awkward to use, and the cursor accuracy is not enough. Long-term forced use will cause body damage.
