Abstract

The invention discloses a method for realizing a shortcut key mode on a touch pad of a notebook computer. The method comprises the following steps of: dividing the touch pad into a plurality of zones, wherein each zone defines a corresponding shortcut key command; calculating the zone range of the center point touched by a finger, and sending the corresponding shortcut key command to the system; during use, sensing the finger within the setting time when the finger is touched with the touch pad in a stay state or a sliding state, and determining that a touch mode is a single-finger mode or a double-finger mode at the same time, according to the sensing result, switching to a shortcut key mode or a mouse mode; (1) touching: when the single finger or the double fingers of a user touches/touch the touch pad, the finger does not displace within setting time; according to the program setting of the single-point touch or the double-point touch, switching to a shortcut key mode, and sending the shortcut key command according to the touch position on the touch pad; and (2) sliding: the single finger of the user just touches the touch pad and moves and does not stay, so a cursor sliding mode is switched and a cursor correspondingly slides on the display screen.

Description

On the notebook computer Trackpad, realize the method for shortcut pattern

Technical field:

The present invention relates to a kind of field of computer technology, especially relate to the touch pad technology field that notebook calculates.

Background technology:

The computed frequency of modern is high especially, in general computer operation, often need open several working software forms on screen, as document or folder forms such as WORD, EXCEL, and EXPLORE browsing software and Email.Except operating with mouse, also available keyboard shortcut operation for notebook, when above-knee operation, use the dirigibility of Trackpad mouse relatively poor as if no desk, and keyboard shortcut is to select preferably.

The keyboard shortcut operation all must be by two keyboards, as CTRL+F4, ALT+F6, and kind is many especially, and different software also is not quite similar to the setting of shortcut, even also different after the same software correcting, so general user can not adopt the shortcut pattern.A lot of notebook computers can be equipped with the independent shortcut or the self-defined shortcut of software of some on keyboard, but these key factor amounts are limited, can only be limited in quick startup application program or realize specific function, seldom relate to window-operating.Some notebook computer is provided with touch music operating key above keyboard, the rising that brings cost but palpus increases the touch-control chip.

In addition, though some Trackpad right and left key below is provided with the audio-visual operating key of Trackpad near card edge or keyboard top, also establishing a touch-control module in addition because of needs increases cost.

Fa Zhan many fingers Trackpad can realize that webpage page turning, photo amplification are dwindled, photo overturns and the function of other shortcuts instructions, but the function that can be provided with was few afterwards, because each function all must be remembered a kind of method of operating, used still inconvenient.

Summary of the invention:

The objective of the invention is to the weak point that exists at prior art and a kind of method that realizes the shortcut pattern on the notebook computer Trackpad is provided, it has cost characteristics low, flexible and convenient to use.

For achieving the above object, of the present inventionly realize that on the notebook computer Trackpad method of shortcut pattern is that Trackpad is divided into a plurality of zones, the corresponding shortcut instruction of each zone definitions, calculate the finger point and touch the regional extent at central point place, system is sent corresponding shortcut instruction; During use, Trackpad detecting finger is stop state or sliding mode in rigidly connecting the one section setting-up time that touches, and judges it is single finger print formula or two finger print formula simultaneously, according to the detecting result, switches to shortcut pattern or mouse mode;

(1) touches, when Trackpad is hit in user's single finger or two indication, non-displacement in the time of setting then touches or setting that two indication is touched single the indication according to program, switch to the shortcut pattern, and touch the position according to its point on Trackpad and send the shortcut instruction;

(2) slide, singly the referring to rigidly connect to touch in the Trackpad card of user, promptly move and do not have stop, then be the cursor sliding-modes, and correspondingly slip on display screen.

Preferred as technique scheme, Trackpad is divided into the two rows zone, and each row is divided into 5～8 zonules, can send 10～16 shortcuts instructions, and outward flange is printed with the shortcut symbol above or below the Trackpad.

Preferred as technique scheme, described Trackpad is for supporting the Trackpad of multi-point touch, Trackpad detects two fingers and puts on the Trackpad card and touch, and is then to send different instructions according to the zone that it contacted by stop state non-displacement in rigidly connecting the one section setting-up time that touches; The method of judging the finger touch zone is: calculate the position of two fingers, and calculate itself and the distance of Trackpad coboundary respectively, the chosen distance reckling is the zone of user's selection, instructs thereby system is sent corresponding shortcut.

Beneficial effect of the present invention is: it does not adopt too complicated many fingers touch control procedure, and program is greatly simplified; In addition, it is more directly perceived, by at the quick keyboard symbol of Trackpad next door printing, needn't remember too many many fingers touch control operation mode in the use, uses very flexible.

Description of drawings:

The present invention is described further below in conjunction with accompanying drawing:

Fig. 1 is a Trackpad synoptic diagram of the present invention;

Fig. 2 is the software flow pattern of the embodiment of the invention one;

Fig. 3 is the software flow pattern (two indications are touched in the same area, and point touches in zones of different then is failure to actuate) of the embodiment of the invention two;

Fig. 4 is the software flow pattern (two refer to one in front and one in back) of the embodiment of the invention three.

Embodiment:

Therefore the following stated does not limit protection scope of the present invention only for embodying the preferred embodiment of the principle of the invention.

See shown in Figure 1: Trackpad of the present invention is divided into the two rows zone, and each row is divided into 5～8 zonules, can send the instruction of 10～16 shortcuts, and outward flange is printed with the shortcut symbol above or below the Trackpad.

See that Fig. 2 is to shown in Figure 4: during use, Trackpad detecting finger is stop state or sliding mode in rigidly connecting the one section setting-up time that touches, and judges it is single finger print formula or two finger print formula simultaneously, according to the detecting result, switches to shortcut pattern or mouse mode;

Trackpad is for supporting the Trackpad of multi-point touch, and Trackpad detects two fingers and put on the Trackpad card and touch, and is stop state non-displacement in rigidly connecting the one section setting-up time that touches, and then sends different instructions according to the zone that it contacted; The method of judging the finger touch zone is: calculate the position of two fingers, and calculate itself and the distance of Trackpad coboundary respectively, the chosen distance reckling is the zone of user's selection, instructs thereby system is sent corresponding shortcut.

Next Trackpad of the present invention judges the zone that the user selects after entering two indication touch formulas; Because the Trackpad zoning may reach 12, user's two refers to contact zones of different, therefore after requiring the user to select the zone, with the Trackpad edge of a finger near the selection zone, if last row zone is then near coboundary, if following row zone is then near lower limb, and another finger gets final product near the Trackpad center line.The method of judging the finger touch zone is: the position (X1 that calculates two fingers, Y1), (X2, Y2), and according to | Y1-Y0|, | Y1-Yn|, | Y2-Y0|, | the distance of these several numerical evaluation of Y2-Yn| and Trackpad coboundary, wherein, Y0 is the Y coordinate of Trackpad lower limb, Yn is the Y coordinate of Trackpad coboundary, reckling is in these four numerical value | Ys-Y0| or | Ys-Yn|, (Xs then, Ys) promptly be identified as the user and select, afterwards according to (Xs, Ys) regional extent at place is sent corresponding shortcut instruction to system.For example (X2, Y2) near coboundary, (X1, Y1 is near center line, then | and the numerical value of Y2-Yn| is necessarily minimum, therefore so that (X2, Y2) the shortcut instruction is sent in the band of position at place.

Select shortcut, need to consider following some: the action that (1) is the most frequently used; (2) action that will do immediately among the editor or when finishing; (3) must repeatedly click the work that just can finish behind the menu.

Because different application software may have different order numbers at identical shortcut, for example the ratio of inspecting is closed form.Can in system, move an application program, the application program of regularly detecting present system ENABLE is any, for example be OFFICE or PDF or picture file, if the programing change of ENABLE is arranged, for example originally operate WORD and operate EXCEL instead, then this spy software is sent out an instruction notification Trackpad, the application program of the ENABLE of announcement and version, make Trackpad to same function, but because of the difference of ENABLE program, and send different operational orders.
