Embodiment 1

[0046] Such as figure 1 , 2 As shown, a method for displaying and controlling a line-of-sight cursor, comprising the following steps:

[0047] S1. Set trigger time T1, release time T2 and second release time T3, T1≥T2≥T3;

[0048] S2. The time when the line of sight acquisition device acquires that the fixation point falls on any target activation area reaches the trigger time T1, then the target starts to be in the pre-trigger state; when there is a target in the pre-trigger state, a locked line of sight cursor appears in the target activation area;

[0049] S3, judging whether to confirm the pre-triggering state of the target, if so, then enter step S4; if not, then judging that the pre-triggering state of the target is released; if image 3 As shown, step S3 further includes the following steps:

[0050] S31. Judging whether the time for the gaze point to transfer from the activation area of ​​the pre-trigger state target to another target activation area reaches the sec...

Embodiment 2

[0067] This embodiment has different pre-trigger state release mechanisms, cursor display methods, and application scenarios from Embodiment 1.

[0068] Such as Figure 6 As shown, a method for displaying and controlling a line-of-sight cursor, comprising the following steps:

[0069] S1, set trigger time T1 and release time T2;

[0070] S2. The time when the line of sight acquisition device acquires that the gaze point falls on any target activation area reaches the trigger time T1, then the target is in the pre-trigger state;

[0071] S3, judging whether to confirm the pre-triggering state of the target, if so, then enter step S4; if not, then judging that the pre-triggering state of the target is released; step S3 further includes the following steps:

[0072] S31. Determine whether the gaze point is transferred from the activation area of ​​the pre-trigger state target to another target activation area, if yes, repeat step S2; if not, enter step S32;

[0073] S32. Deter...

Abstract

The invention provides a method and system for displaying and controlling a sight cursor, and the method comprises a display system, a sight obtaining device, and a physical key; a pre-trigger state of a target and a pre-trigger state release mechanism are set to complete the click of a selected target activation region through the physical key. According to the method and system for displaying and controlling a sight cursor, the problems that positioning of the sight line cursor is prone to interference and Midaus contact exists are solved, and the experience and efficiency of eye movement interaction are improved.

Description

technical field [0001] The invention relates to the technical field of eye movement interaction, in particular to a method and system for displaying and controlling a sight cursor. Background technique [0002] With the rapid development of eye-tracking technology, there are more and more applications using human eye-movement information to interact with systems in recent years, such as providing eye-control input means for disabled people with limited physical activity, and improving the efficiency of information exchange between disabled people and the outside world ; In the field of consumer electronics such as tablet computers, provide operators with an eye-machine interaction mode to improve the operator's interactive experience. [0003] However, due to the characteristics of unconscious tremors in the human eye, when using sight to control the cursor positioning, if the cursor is controlled by a device such as a mouse or a touchpad to display the cursor in real time, ...
