Description
Technical field
The present invention relates to the position input technology of portable electric appts, especially relate to a kind of touch control type information input device and method.
Background technology
The invention of keyboard and mouse is a lot of convenience for people bring, and are used fully in the rapid development of computer technology process, and the technology of keyboard and mouse itself also changes thereupon.For the keyboard that stems from mechanical type English alphabet typewriter the earliest, though all there is not too many variation on its basic configuration, the principle, for example cardinal principle still is an XY array scanning mode, or Mechanical Contact formula or capacitor induction type, but at aspects such as volume, use feeling, life-span, lightweight, costs very big variation has taken place all.For the mouse that stems from XY axle image input instrument the earliest, from the X/Y shaft mechanical formula mouse that begins most to photoelectric reflection formula mouse, the photoelectric coding mechanical wheel rotates mouse, till now light image position transducer mouse again, the performance of mouse, reliability, precision etc. all obtain tremendous development.Mouse function also has bigger expansion, such as increasing roller operation etc.
Along with the development of infotech and to the rising of mobile computing demand, people have proposed new demand to the location input device of mobile model or portable computer, be exactly in portable computer, the volume of location input device needs smaller, is fit to carry; And constitute an integral body with portable computer, the action of plug so just need not arranged when using portable computer, also need not the line that the outside hangs, make outward appearance relatively more neat and clean.
Because mouse (the especially ball of Gun Donging) volume itself is too big, the mutation of integrating mouse and mouse is restricted such as trace ball etc. on portable computer, therefore limited in notebook computer application on the whole, but itself with regard to mouse, still meet very much human oriented design: at first be the operation that is fit to very much hand, the finger natural torsion is placed on the mouse, and when wrist moved, finger did not need firmly; Next is that moving range is very big, and mobile accuracy is high and very sensitive.So need pinpoint occasion at some, such as drawing, play games etc., still need the location input device of mouse and so on.
Exist some keyboard and mouse to be carried out the technical scheme of combination in the prior art.Such as top be keyboard, keyboard below or next door are mouse, perhaps by the quantity of reduction keyboard, reach the purpose of singlehanded control by the mode of key combination.But there are some defectives in these prior aries: on the one hand and existing keyboard, the mouse use habit is inequality and be difficult to allow the user accept; On the other hand, traditional mouse needs a relatively flat plane to allow mouse move in the above, so in mobile office, be subjected to a lot of restrictions, such as in aircrafts such as airport, be not equipped with chain-wales on the seat that the passenger on general airport waits, this makes the application of the mobile class mouse pointing device of rolling be greatly affected; In addition, keyboard and mouse links together, and still needs to carry out wired being connected with main frame, if all adopt wireless mode, cost can compare higher.
In present portable computer, except the grafting common mouse, relatively Chang Yong integrated location input device mainly contains three classes: the first kind, Track Point (TRACK POINT), certain position in the middle of keyboard embeds a Track Point, according to finger shaking on Track Point, produce position signalling,, determine the position of cursor on display by detecting the variation of these signals; Second class, Trackpad (TRACKPAD), below the keyboard or near a little touch window is set, finger moves on window, the variation of resistance, electric capacity or variation inductance perception finger position by window lower floor; The 3rd class, touch pad (TOUCH PANEL) generally is provided with the sensing device layer, or display surface is provided with transparent sensing layer below display screen, generally also sub-resistance formula, condenser type, inductance type, infrared type etc. adopt the scheme of auxiliary locators such as stylus, magnetic pen, light pen in addition.
Wherein, the benefit of Track Point is that volume is very little, and the area of bar is also littler than the button of keyboard, but because the problem of use habit, operation is not very convenient; And in the mouse moving process, finger will be exerted oneself always; Because according to the firmly big or small shift length and the velocity of displacement of judging cursor of finger, accurate positioning is not easy to; And the button of control usefulness is distant apart from Track Point distance, this make the user must spread one's fingers (thumb and forefinger) operate or two manual manipulations.
Touch pad is then relatively more directly perceived, directly in image display frame, operate, but precision is not very high, relatively be fit to panel computer, PDA (personal digital assistant) etc. does not have the occasion of keyboard, though can realize handwriting input, input speed can not show a candle to the input speed of keyboard and mouse combination with regard to present technology.
Trackpad handling relatively good can one-handed performance, and relatively more directly perceived, and volume is also less, and is more durable, therefore at present in notebook computer application wider.General sub-resistance formula of Trackpad and condenser type, capacitive position detection method performance in every respect are all preferable relatively.
See also Fig. 1, be the schematic diagram of capacitive position detection method.Wherein, Trackpad comprises bottom plate 2, surface insulation layer 3 and sensor strip 4,5. Sensor strip 4 and 5 adopts the PCB (printed circuit board (PCB)) of standard or flexible circuit technology to constitute the fixation of sensor array, voltage acts on four jiaos of Trackpad and forms a stationary electric field, when pointing 1 when superficial layer moves, electric capacity from finger 1 nearest sensor strip changes, by the variation of this capacitance, make electric field cause electric current, measure via controller (figure does not show), according to the ratio difference of current distance, promptly can calculate the position of finger 1 from four corners.Concrete principle as shown in Figure 2.Computing formula is X=i
2/ I*a; Y=i
3/ I*b; I=i
1+ i
2+ i
3+ i
4Wherein, a and b represent long and wide respectively.
It is pointed out that capacitive touch control plate only all responds to finger, palm etc., but to not reaction of nail, the characteristics that is to say capacitive touch control plate are to the body capacitance sensitivity, but insensitive to the area of contact.Because condenser type overcomes the influence that has the clutter that static produces, large-area contact area has all been removed when eliminating clutter, only write down the position of the central point of contact area, so can't distinguish a finger or whole palm is superincumbent moves.
Although Trackpad is the most popular on notebook computer, on handling, also there is place really not as common mouse, this also is the very important reasons of a lot of notebook computers mouse presented with machine in sales process.
Trackpad is handling not good mainly from following factor: at first be position problems, Trackpad generally is positioned at the below of keyboard, near the position of space bar, and space bar generally carries out button operation by thumb, in the operation of reality, thumb is often run into Trackpad easily, cause cursor position to move, and because Trackpad is comparatively sensitive, if careless words, cause maloperation easily and on the position of mistake, import, influence the efficient of keyboard input; Next is that one-handed performance is not easy, because the position between button and the Trackpad is not suitable for one-handed performance, and it is also inequality with the use habit of common mouse, therefore the cursor key operation of wanting to finish with Trackpad some more complicated is the comparison difficulty, such as play games, picture etc., still convenient, flexible not as common mouse; It is too far away to be that localization part leaves keyboard once more, displacement is distant in frequent keyboard and Trackpad blocked operation, and at every turn when moving on on the keyboard from Trackpad, finger need be reorientated, such as finding the F of raised indicia key and J key are arranged on the keyboard, so still pretty troublesome.
Compare with common mouse, also there are some weakness in Trackpad of the prior art: at first be that the location is not accurate enough; Next is that mobile efficient is low, and cursor is moved to the lower right corner from the upper left corner, need to move the upper left corner from Trackpad to the lower right corner twice; Be far away once more from keyboard; Be different once more with original mouse use habit, the button of mouse and the cooperation of hand are all fixed, no matter where the mouse entity moves to, the operation of finger all is the same, but the control button can not move along with moving of finger on the Trackpad, therefore finger is in some extreme positions, and finger is felt very tried because of extremely stretching.
In addition, the mated condition of Trackpad and keyboard is not as Track Point, and also not as Track Point, this is parallel side by side placement because of keyboard of the prior art and Trackpad on volume is arranged, be subjected to the restriction of notebook volume, therefore think that further reduced volume will compare difficulty.
In the prior art, a kind of Trackpad is disclosed in the Japanese documentation that application number is JP 20000336810, diverse location at Trackpad is provided with difference in functionality, can improve the operation convenience degree of Trackpad to a certain extent, realize a lot of functions simultaneously, such as roll, window operation etc., can also custom feature.See also Fig. 3, Trackpad 10 comprises touch area 34, is positioned at regional 38a, 38b, 38c and the 38d of the definition difference in functionality in four corners, two buttons 18, tool roll the up and down zone 36 of function and the switch 33 of Trackpad and the pilot lamp 35 of Trackpad.
Because the expanded function scope of Trackpad is very big,, can also increase the function of a lot of additional extension, such as rolling move left and right, browser forward-reverse etc. up and down along with the suitable increase of the area of Trackpad; Can also on Trackpad, define a lot of shortcuts zone; This be common mouse and Track Point can't provide, can only handle by increasing button because if want on common mouse and Track Point to increase new function, thereby on volume, propose more requirement.Just because of Trackpad provides this convenience, make on portable computer from now on, to have more long-range development.
But, there are some defectives in the Trackpad of the prior art: these provide the position of expanded function relatively fixing, just can't resemble and tightly follow moving of palm along with moving of mouse main body the common mouse in case set the back, cause the finger manipulation inconvenience.
Another kind of prior art can be consulted the american documentation literature that the patent No. is US 6750852.The prior art has discussed how to point the method for the gesture of moving in identification on the Trackpad on Trackpad in detail, this method mainly is by the residence time and the interval time relatively pointed on Trackpad judging that gesture is mobile on a large scale, or little moved further, reach whereby and on little Trackpad, realize moving significantly and pinpoint purpose, and can further discern various gestures, improve the efficient of Trackpad control cursor.But still can't solving, this technology how to make Trackpad use the same problem easily with mouse.Adopt the technology of Time Calculation, this method relates to complicated calculating, make reaction velocity influenced by some, the cost height, much help the method for raising the efficiency though provide, compare or be not so good as with common mouse, this makes the application of Trackpad be subjected to certain restriction, such as the professional, generally can select for use optical mouse to be used as the input media of cursor position.

Embodiment
Design of the present invention is derived from careful observation and research, the user's of the common mouse of discovery notebook computer operational motion has following characteristics: adopting arm to move in the rolling mouse significantly, after arriving approximate region fast, adopt wrist and finger to carry out careful adjustment.These characteristics meet the principle of ergonomics very much, and this is because the arm of human body is all grown much than the finger wrist, and control accuracy is so inaccurate, and the motion of finger and wrist wants accurately a lot, although displacement is limited; And in the mouse movement process, the division of labor in addition of wrist and finger, the fine setting before and after finger is mainly finished, the rotation of moving and being with certain radian about wrist is responsible for, this also is the essential characteristic that ergonomics draws.
The present invention is according to above principle, propose a kind of on the basis of existing Trackpad improved a kind of apparatus and method of simulating the common mouse function, to improve the efficient of position input, meet the use habit of common mouse.
Seeing also Fig. 4, is the block diagram of touch control type information input device of the present invention.
Touch control type information input device comprises user operation unit 110, position information process unit 120, interface unit 130 and mouse function converting unit 140.
Wherein, user operation unit 110 perception users' operation and produce corresponding electric signal; 120 of position information process unit detect described electric signal, and calculate the position that the user touches according to this electric signal, send position signalling to interface unit 130; Interface unit 130 is exported to mouse function converting unit 140 with described position signalling; Mouse function converting unit 140 completing place signals are to the conversion of mouse input information.Described mouse input information comprises moving cursor, acknowledgement key, roller operating key, cancel key etc.
See also Fig. 5, in an embodiment of the invention, user operation unit 110 adopts Trackpad; Position information process unit 120 adopts the Trackpad control circuit; Interface unit 130 adopts keyboard controller (EC); 140 of mouse function converting units adopt the Trackpad driver.
Its principle of work is: the Trackpad control circuit is responsible for calculating the position output of the position pointed on the Trackpad and a plurality of fingers, and position signalling exported to keyboard controller EC by standard interface PS/2, export to the Trackpad driver by keyboard controller EC then.The Trackpad driver is responsible for the initialization Trackpad, and the action to Trackpad makes an explanation in operational process, and goes to notify events corresponding formation 520 by operating system nucleus 510.
See also Fig. 6 and Fig. 7, a bigger Trackpad serves as user operation unit 110, the similar enough palms of size move freely in the above, for example with present notebook computer on the keyboard size similar, perhaps with the much the same Trackpad of C face size of notebook computer.
Described Trackpad 110 is surveyed the situation of movement of the whole palm of user.
The situation that the palm that detects is touched Trackpad 110 is done a classification: palm class 910 and finger class 920.And, calculate the position of computer cursor according to the absolute location coordinates of palm 910 and finger 920; According to the relative position between finger 920 and the palm 910, determine the function of zones of different on the Trackpad 110.Specifically, at first determine the position of palm 910 on Trackpad 110, secondly according to this position, in the environs that can set, according to the position of finger 920, the different function of definition on the different relative position of Trackpad, the operation of simulating common mouse whereby.
In the present embodiment, the operation of forefinger 921 is defined as moving cursor and acknowledgement key, the operation of middle finger 922 is defined as roller key and cancel key.
Display highlighting on screen (figure does not show), this cursor can move along with moving of finger, and track is identical with finger.On Trackpad 110, location definition is an acknowledgement key near forefinger 921, and on Trackpad 110, middle finger 922 can be defined as cancel key and roller key by fallen locational near zone.
Present embodiment is determined functional areas according to relative position, and therefore when forefinger 921 moved, these relative positions also and then moved together.
Distance between forefinger 921 and the middle finger 922 can adopt multiple mode to determine, as according to setting value, measured value or empirical value are determined in advance.
So-calledly be meant the distance that configures forefinger and middle finger in advance according to setting value, this distance varies with each individual, and is either large or small, on the position or following.
The so-called measurement in advance was meant before using Trackpad 110, earlier the mode of palm according to normal operations is placed on the Trackpad 110, Trackpad 110 calculates distance between forefinger 911 and the middle finger 922 according to the position probing of the contact of middle finger 922 and forefinger 911.
So-called rule of thumb value is meant the hand size according to most of users, comes pre-set this distance.
In a word, the touch control type information input device of present embodiment detects the positions of different fingers, and the outgoing position signal is determined the coordinate of cursor according to absolute location coordinates; Relative position according to each finger is determined the functional definition district, and according to the operational circumstances output signal of each functional areas, comprises enter-key signal, cancel key signal, roller signal etc.
Because need utilize the position signalling of a plurality of fingers, and utilize Trackpad itself can't discern user's hand attitude, therefore, the present invention adopts following method to judge user's operation information:
When only detecting a finger on Trackpad the time, with the position as cursor, the position of this finger, its processing procedure can be the same with prior art.
When detecting two fingers simultaneously on Trackpad the time, with the position as cursor, the position of the finger on the left side, and near the Trackpad position that defines this finger is a left mouse button; With the location definition of the right finger is right mouse button, and near the position of definition the right finger is the POF that rolls.(with the right-hand operated is example, can certainly handle the operation of left hand according to same method.)
When detecting palm and two fingers simultaneously on Trackpad the time, according to the relation of palm and finger relative position, the position of definition palm because the area of palm is bigger than finger, can obviously distinguish earlier; The finger that is defined in position, the palm upper left corner then is cursor position and left mouse button, and the finger of position, the upper right corner, palm position is right mouse button and roller position.
When palm and finger are not simultaneously on Trackpad the time,, then define according to the method described above if finger is arranged earlier; When in the ban palm being arranged, then define first finger and be cursor position and left mouse button; When second finger occurring, the method when palm and two fingers are simultaneously on Trackpad defines again.
For the ease of the understanding of the present invention, describe the present invention below in conjunction with instantiation.
See also Fig. 8, example of the present invention is the message input device that is applied to notebook computer 800.
On the C face of notebook computer 800 original placement keyboards, place a monoblock Trackpad 110, the similar size of big or small keyboard with present common laptop is identical, and this laptop 800 adopts capacitance keyboard, that is to say that this Trackpad 110 can be realized the function of character input and position input; For fear of maloperation, character input and position input are distinguished in time, therefore, this message input device also comprises change-over switch 150; Described change-over switch 150 is placed on the lower left of Trackpad 110.
Wherein, the hardware system of Trackpad 110 composition and prior art are similar, and only Trackpad 110 areas are bigger, can allow hand move freely on Trackpad 110 like this.
The all keys of mouse all replace with the operation on the Trackpad, and keyboard adopts capacitance keyboard, therefore on the notebook C face except power switch and keyboard and mouse change-over switch, there is not other button, therefore seem clean and tidy especially clean, and the capacitance keyboard Trackpad reaches the purpose of waterproof easily.Keyboard still is decorated with on the Trackpad surface, to make things convenient for the capturing position input.
The principle of work of capacitance keyboard and prior art roughly the same: promptly do not need keyboard controller initiatively to send out impulse level, as long as the finger contact will produce capacitance variations in the contact position and be reflected in the electric current variation, the keypad information processing unit of keyboard controller (figure does not show) changes the position of calculating button according to electric current, and tables look-up and realize the identification of button.
Analog mouse operation in this example, following principle (with the right-hand operated mouse is example, and the rest may be inferred for the situation of left-handed operation mouse) is followed in the motion of identification finger:
When the Trackpad control circuit detects the position of first finger, with the position output notebook computer of this position as cursor; Near this position touch pad area is defined as left mouse button, when finger is heavily pressed or is double-clicked, output left mouse button signal;
When the Trackpad control circuit detects the position of second finger, if the position of second finger in the left side of first finger position, then second finger handled when pointing as new first, former first finger becomes second new finger; If the position of second finger is on the right side of first finger position, then the finger order is constant, and the position of cursor is moved with the position of first finger and is moved, and first finger position near zone is a left mouse button, and output left mouse button signal is given notebook computer when heavily pressing or double-clicking; Be right mouse button zone and roller zone near second finger position, when heavily by or when double-clicking this zone, produce the right mouse button signal and export to notebook computer, do in this zone when sliding up and down when pointing, generation roller signal is exported to notebook computer.
When also having the 3rd finger to detect, the position signalling of the 3rd finger is ignored, in order to avoid produce misoperation and confusion.
Relation is for facing the user of notebook about the relative position of the above finger, and when becoming first new finger when second finger, cursor position does not change, just the cursor relation of following changes: follow moving of former first finger by original, change into and follow moving of first new finger.
Seeing also Fig. 9, is the process flow diagram of realizing position input and mouse function operation in this example.
Step S110 judges whether by finger contact Trackpad; If then enter step S120; If not, then beginning a new round judges;
Step S120 detects finger position, and exports as cursor position;
Step S130, judged whether heavily by or double-click signal; If then enter step S140; If not, then return step S120;
Step S140, output left mouse button signal;
Step S150 judges to have or not second finger contact; If then enter step S160; If not, then bring into play step S120;
Step S160 judges that whether second finger be in first finger left side; If then enter step S170; If not, then enter step S180;
Step S170, second finger becomes first new finger, and first finger becomes second new finger, enters step S180;
Step S180 carries out the position and handles, and heavily pressing of two fingers handled and the roller processing.
See also Figure 10, first face is introduced the relevant concrete treatment scheme of step S180.
Step S210, cursor position originally is constant, and move the position that cursor position is followed first finger;
Whether step S220 has and double-clicks or heavily by operation; If have, then enter step S230; If not, then enter step S260;
Step S230, judgement is the operation of first finger or second finger; If first finger then enters step S240; If second finger then enters step S250;
Step S240 produces left mouse button signal and output;
Step S250 produces right mouse button signal and output;
Step S260 has judged whether to slide up and down operation, if then enter step S270; If not, then return step S210;
Step S270 judges whether the operation of second finger, if then enter step S280; If not, then return step S210;
Step S280 produces roller signal and output, in order to drive corresponding application.
(with the right-hand operated is example in another example of the present invention, the method of left-handed operation can the rest may be inferred), with example class shown in Figure 8 seemingly, difference is: the finger number increases, and separate processes, is the center with the palm, forefinger is defined as cursor positioning, thumb is defined as left mouse button, and middle finger is defined as the roller operation, and the third finger is defined as right mouse button.
Its workflow is roughly: press earlier the position that area calculates palm, point or the calculating of palm contact area about Trackpad, can adopt the vicissitudinous sensor of electric current counted and realize.Calculate the position of thumb then, because these two areas that contact on Trackpad are bigger, identification is defined as forefinger at first finger position of thumb right side then easily, and second finger is defined as middle finger, and the 3rd finger is defined as the third finger.All the other and example class shown in Figure 8 are seemingly.
Certainly, also can adopt traditional mechanical type keyboard to carry out the character input; At this moment, Trackpad can only be used for the operation of analog mouse, and this does not give unnecessary details.
Be appreciated that, the present invention is not only applicable to notebook computer, can also be applied to other similar portable electric appts, thus the operation that comes analog mouse by the mode as the touch-control, thereby reduce the volume of portable electric appts, make that the picture and text input is convenient.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
