Cursor control method

Abstract

The invention discloses a cursor control method, which comprises the steps of: defining three characteristic points of a moving piece; sensing parameter change of the three characteristic points between two time points; and correspondingly moving a cursor according to the parameter change.

Problems solved by technology

[0002] Various types of mice on the market have become an indispensable part of the human-machine interface communication of various electronic products. Traditionally, the scroll wheel of the scroll wheel mouse is easy to stick to the table and be damaged after rolling; and The optical mouse cannot respond sensitively on certain types of desktops (such as glass desktops); the two traditional mice mentioned above cannot respond directly, quickly and sensitively to the user's desire to issue a cursor on the screen. instruct

[0003] Discussing the major unresolved problems related to the mouse: (1) the traditional mouse cannot immediately respond to the movement instructions issued by the user to the cursor on the screen. the inconvenience

For example, take a first-person point-of-view shooting game as an example. Players must manually control the movement of the mouse next to the desired field of view displayed on the screen in their minds. This will increase the response time and be very inconvenient; on the other hand, the actual field of view It can't be fully synchronized with the hand movements, that is, it is easy to cause the player to gradually become dizzy while playing the game, which will inevitably produce side effects that are harmful to health

(2) As far as the notebook computer (NB) is concerned, its advantage is that it strives for convenience, but the touch pad (touch pad) on the notebook computer that controls the screen cursor is very inconvenient to use, so that most notebook computer users will use it separately. If you buy a mouse, the desktop area required for work will be much larger than the area of ​​the laptop, and when using NB in ​​a small space, such as the seat of an airplane or other means of transportation, it is impossible to use the additional mouse. A mouse that makes a laptop lose its convenience

And the shortcoming of this kind of prior art and the reason of not popularizing are: (1) this prior art needs more than two high-resolution video cameras, just can discern the eyeball movement that this action is very subtle to video camera in three-dimensional space, so the whole system The cost is extremely high; and this design is very unfavorable for the application on small computers such as mobile phones and PDAs

(2) In the three-dimensional space, the focus of the user's eyes and the calculation of the focus direction change caused by the rotation and movement of the head are very complicated and consume a lot of computer hardware resources. Not only is it not conducive to the application of small computers, it may also be unfavorable Applied on low- and medium-priced personal computers, so it is not easy to popularize

(3) If the cursor moves with the focus of the user's line of sight, it may cause the cursor to block the user's line of sight and cause inconvenience

[0005] Therefore, how to improve problems such as the need for two or more high-resolution cameras to identify very subtle eyeball movements, the calculation of focus direction changes is very complicated, and the inconvenience of the cursor blocking the user's line of sight, after the inventor conducted experiments, tests and researches. , and finally obtained a cursor control method, in addition to effectively solving the shortcomings of requiring two high-resolution cameras, very complicated calculations, and the cursor blocking the line of sight, it can also achieve the effect of allowing the screen cursor to "real-time" achieve the user's instructions
