Embodiment
In order to make content of the present invention more clear, below the example that can implement according to this really as the present invention especially exemplified by embodiment.
Fig. 1 is the synoptic diagram of the Trackpad integration system of the multiple functional modes that illustrates according to one embodiment of the invention.See also Fig. 1, the Trackpad integration system 100 of multiple functional modes comprises judge module 110, handover module 120, and execution module 130, in order to multiple functional mode is incorporated into same Trackpad (touch pad), and according to the user to changing between the different functional mode of operating in of Trackpad, to carry out corresponding function.
Wherein, judge module 110 judges in order to when receiving first signal whether first signal meets trigger condition and whether first signal continues to exist.For instance, when first signal is when being triggered by a particular switch, judge module 110 judges that first signal accords with trigger condition.Wherein, particular switch for example is to set up in the Trackpad outside or an entity switch of Trackpad central authorities, the kind and the position of particular switch is not limited at this.In addition, be when being triggered at first signal by Trackpad, judge module 110 also can judge whether first signal meets trigger condition according to the specific region whether pairing changes in coordinates value of first signal is positioned on the Trackpad.Moreover, judge module 110 can also according to first signal whether by the compound keys (compound key) of keyboard triggering (for example judging whether the user pushes several specific buttons on the keyboard simultaneously), or whether judge by operation interface that application-specific provided such as is triggered at condition whether first signal accords with trigger condition according to first signal.
See through the running of the Trackpad integration system 100 of multiple functional modes, as long as first signal accords with trigger condition, Trackpad just can switch to second functional mode by first functional mode.And under the situation that first signal continue to exist, Trackpad will remain on second functional mode, and then allow the user can utilize Trackpad to import second signal, carry out function under second functional mode with correspondence.In following embodiment, will come the present invention is further illustrated with the method for operating of the Trackpad of having integrated multiple functional modes.
Please consult Fig. 1 and Fig. 2 simultaneously, in the present embodiment, suppose that Trackpad is set to first functional mode at present.Under first functional mode, Trackpad is to be in general user mode so, and the user can see through touching or click Trackpad and carry out the moving cursor position, choose object, or conventional mouse function such as towing object.When the user wishes to utilize Trackpad to carry out specific function, then can trigger the functional mode that first signal comes switching contact control panel.This moment, the Trackpad integration system 100 of multiple functional modes received first signal that the user triggered shown in step 210.Wherein, first signal can trigger by the operation interface that compound keys or application program provided of hardware switch, Trackpad, keyboard, does not limit its scope at this.
Then in step 220, judge module 110 judges whether first signal meets trigger condition and whether first signal continues to exist.Wherein, first signal that meets trigger condition for example be by particular switch triggered, the compound keys that triggered, push keyboard by the specific region on the Trackpad triggered, or triggered or the like by the operation interface that application-specific provided.If judge module 110 is judged first signal and is not met trigger condition or the disappearance of first signal, so shown in step 230, Trackpad will maintain first functional mode, and then this operating process will be got back to step 210, receive first signal that the user triggers once more and it is judged.
Otherwise, continue to exist if meet first signal of trigger condition, in step 240, handover module 120 switches to second functional mode with Trackpad by first functional mode so, and makes Trackpad maintain second functional mode.Furthermore, before Trackpad entered and maintain second functional mode, handover module 120 was at first obtained a function contrast that has write down the multiple second class function.Then, distinguish Trackpad according to the quantity of the second class function in the function contrast, and then Trackpad is divided into several zones.Next, assign each second each self-corresponding zone of class function respectively according to division result.Corresponding relation with each second class function and zone writes down back function contrast at last.After finishing above-mentioned action, under the situation that continues to exist at first signal that meets trigger condition, Trackpad is just no longer supported the conventional mouse function that former factory of Trackpad manufacturer sets, but the zone of coming out with division is a unit, and the second different class functions is provided separately.
At last shown in step 250, Trackpad receives second signal and because first signal exists when making that Trackpad maintains second functional mode simultaneously, execution module 130 is carried out the second class function of correspondence according to the pairing changes in coordinates value of second signal seeing through.In the present embodiment, execution module 130 judges that at first the pairing changes in coordinates value of second signal is which zone that is positioned on the Trackpad, and the comparison function contrast is to obtain this area relative second class function.Then capture the motion track of second signal, carry out the regional second class function that can carry out that the changes in coordinates value is positioned at according to the direction of motion track again.
Must benly be, have first signal that meets trigger condition only and continue to exist that Trackpad just can remain on second functional mode.In other words, in case first signal disappears, handover module 120 just can switch back Trackpad first functional mode that had before set immediately so.At this moment, the user just can only utilize Trackpad to carry out moving cursor, choose or pull traditional mouse function such as object.
Fig. 3 is the schematic appearance of the Trackpad that illustrates according to one embodiment of the invention.See also Fig. 3, Trackpad 300 comprises button 310, button 320, and be positioned at central authorities a particular switch 330, and except button 310, button 320 and particular switch 330 be the touching operating area.In the present embodiment, Trackpad 300 is redefined for first functional mode, so user's finger that can slide on Trackpad 300 comes the position of moving cursor, or sees through and click Trackpad 300 and choose or pull object.
Yet, in case the user pushes particular switch 330 constantly, Trackpad 300 just can switch to second functional mode by first functional mode, wherein the second included class function of second functional mode for example is picture rolling function, a picture left and right sides rolling function up and down, and the picture zoom function, correspond to zone 340, zone 350 and zone 360 respectively.In one embodiment, along with the difference of each area relative second class function, can on the zone, print corresponding icon or symbol and point out the user this regional scope and function thereof.
For example in Fig. 3, the bold dashed lines that is printed on the Trackpad 300 is zone 340, the zone 350 and zone 360 scope separately that is divided in order to the prompting user.Zone 340 and the dotted line camber line of zone in 350 and arrow then can point out the user in these two zones up and down or horizontally slip and point scrolling picture accordingly.That is to say, when the user continues to push particular switch 330 to point, and when sliding up and down in zone 340 with the another finger, just can be apace up and down scrolling be presented at picture in the screen.And continue to push particular switch 330 to point the user, and when using the another finger to horizontally slip, then can make the picture left and right sides scrolling apace in the screen in zone 350.
In addition, dotted line camber line in regional 360 and plus-minus symbol then in order to the picture of prompting user in zone 360 makes progress the scalable screen of slip finger, then can dwindle picture to the lower slider finger.That is, when the user continues to push particular switch 330 to point, and when using the another finger to slide up and down, then can start picture zoom function and then amplification or dwindle picture in the screen in zone 360.
As mentioned above, Trackpad 300 has been integrated two kinds of different functional modes, as long as just push particular switch 330 and can switch between these two kinds of functional modes.Thus, except the function that Trackpad 300 former factories set, the user is after switching to second functional mode with Trackpad 300, just a greater variety of functions are carried out in the operation that can see through zones of different, make the mode of operation of Trackpad 300 have more interest, allow the user feel convenient more simultaneously.
Fig. 4 is the system architecture diagram of the computer system that illustrates according to one embodiment of the invention.In the present embodiment, when the user operates Trackpad 410, information such as the pairing changes in coordinates value of operational motion are sent to the Trackpad integration system 440 of multiple functional modes via embedded controller 420 and Trackpad driver 430 to the upper strata.And the Trackpad integration system 440 of multiple functional modes will according to the same or analogous flow process of Fig. 2, judge that Trackpad 410 is to belong to which kind of functional mode at present, and should carry out the sort of function.In view of the above, operating system 450 just can be made correct reaction according to the judged result of the Trackpad integration system 440 of multiple functional modes.
In other words, no matter Trackpad 410 is whether belong to the hardware signal value of the function of which manufacturer, advance planning and definition identical, as long as see through the running of the Trackpad integration system 440 of multiple functional modes, just can be after default functional mode switch to another functional mode by manufacturer with Trackpad 410, make that Trackpad 410 is the function that unit provides multiple special definition with the zone.That is the designed Trackpad of any manufacturer all can see through the collocation of the Trackpad integration system 440 of multiple functional modes and use and allow the user carry out the special function that defines on computer system.
The present invention provides a kind of computer program in addition, and it is in order to carry out the operation method of touch pad of above-mentioned multiple functional modes.This computer program is formed (for example setting program code snippet and deployment program code snippet or the like) by several code segment basically, after these code segment being written into computer system and carrying out, can finish the step of the operation method of touch pad of above-mentioned multiple functional modes, and make computer system possess the function of the Trackpad integration system of multiple functional modes.
In sum, the operation method of touch pad of multiple functional modes of the present invention, integration system and computer program are incorporated into the functional mode of traditional function pattern with special definition on the same Trackpad, when judgement first signal meets trigger condition and continues to exist, divide Trackpad and also assign different functions respectively for several zones.Continue to trigger first signal and on Trackpad, slide finger when producing second signal the user in view of the above, carry out corresponding function.Thus, Trackpad will no longer be subjected to the restriction of former factory set-up function, also can carry out other specific function after functional mode switches, thereby allow the user operate more easily, and experience brand-new use experience.
Though the present invention discloses as above with embodiment; right its is not in order to limit the present invention; have in the technical field under any and know the knowledgeable usually; without departing from the spirit and scope of the present invention; when doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the claim person of defining.
