Description

A kind of apparatus and method with character input function
(1) technical field:
The invention belongs to the technology with information input functions such as characters of equipment such as being used for microcomputer, hand telephone set, keyboard.
(2) background technology:
The message input device of prior art mainly is a keyboard, touch-screen etc., for portable or hand-held or pocket equipment, these device volumes are too big, for avoiding maloperation (input press mistiming will be close to other buttons or touch the position push simultaneously) and reduction requirement to the finger keystroke precision, its each button or touch (key position) center, position and both sides button or touch the edge, position apart from sum must greater than in addition obviously greater than the width of pointing the end, therefore, width with input media (as the notebook computer and the QWERTY keyboard of current trend) of more keys or touch position is difficult to dwindle, if obviously reduce the number of button or touch position (key position), the many usefulness of one key can increase the complicacy of operation again and reduce input speed (as existing pocket diary computer, mobile phone and PAD etc.); The pocket input media that utilizes input pen is also arranged, but input is slower, has also increased the trouble of carrying pen and holding a pen.
In order to solve input speed and portable contradiction, some new departures have appearred.Pocket keyboard structure (Chinese publication number 1182907) as Motorola Inc. reduces keyboard with the method that increases the ratio (dwindling button) of button spacing and button radius greatly, but effect is limited.And for example, Israel VKB company attempts to show out the QWERTY keyboard image on the table with miniature laser equipment, and measures finger position and determine input information, but inconvenience use when going out.And for example U.S.Pat.5581484 has described the method that the method for settling acceleration transducer and carrying out integral and calculating at finger tip is judged opsition dependent under the finger, very trouble.
Some other people attempts to utilize touch-screen or clipboard technology to solve this problem, but the surface of contact of finger and touch-screen or clipboard is almost big with common key-press, and the key position is difficult to dwindle.People such as Gruaz utilizes the analysis of numerous sensitive spots that adversary's abutment face downside triggers to determine the center of pushing in U.S.Pat.5459463; Downward projection was dwindled the varistor layer compression area when Yaniger utilized overlayer to be subjected to pressing in U.S.Pat.5053585; People such as Bole utilizes finger position is judged in the calculating of the capacitance-sensitive detectable signal that element obtains of the column distribution of embarking on journey under the overlayer among the U.S.Pat.5463388; These technology are all too complicated, and effect is little, and directly whether perceived position is accurate for finger during touch, has a strong impact on input speed, can not be satisfactory.
(3) summary of the invention:
The objective of the invention is to propose a kind of brand-new scheme, make original keyboard or touch that position (key position) spacing is subjected to the finger width restriction and the problem that can not obviously dwindle is avoided, thereby realize many buttons or touch the position input media or with pocketization of the electronic installation of this device more.Be specifically described below.
The present invention includes a kind of device, accept touch pad (2) that touch objects touches and corresponding signal measurement during by housing (1), for input and partly wait and form with information input function such as character;

As mentioned above, because the output characteristics of strain gauge or sensing element is not strict linear and may drift about, therefore the calculating to the position, touch point usually will comprise very complicated correction, if this drift takes place during use, will bring more trouble, as input error, even correlation technique can't solve with reasonable manner.
In order to address this problem, the present invention proposes and determine the input character that this touch is corresponding or the method (abbreviation method I) of information or instruction when a kind of touch pad that is used to a plurality of keys position is subjected to touching, comprising:
(i) make touch pad within it near side or the edge some (more than 2) diverse location have several direct or indirect support zones that can the suffered touch force of this touch pad of balance, all or part of described support zone or its place support component have (or is exactly) stress sensing element itself, when touch pad was subjected to touching, these sensing elements (or its affiliated signal measurement part) can provide the reflection suffered stress of place support zone (anchorage force) measuring-signal or the data of number change continuously;
(ii) when touch pad is subjected to touch pressure, the numerical value or the ratio of the anchorage force (or its measuring-signal) that the stress sensing element of the geometric position that is distributed according to each support zone of touch pad by the processor of touch pad place system or signal processing or corresponding coordinate data and each support zone or parts (or under it signal measurement part) is measured, calculate the coordinates computed of (can consider touch pad gravity) the position of action point correspondence of making a concerted effort of each anchorage force, this coordinates computed is exactly the coordinates computed of the touch force position of action point correspondence of balance with it;
Described coordinates computed can be but not require must to be real geometric coordinate, but should be corresponding with the latter or proportional by certain rule, can be numeral or code;
(iii) certain or some of each key position of chosen in advance touch pad points (comprising being located on or near the centrical point of key, perhaps mid point or end points or flex point or its points of proximity etc. of key bit boundary or boundary line segment) of having obvious characteristic or differentiating meaning are as the key potential reference point;
(iv) calculate the coordinates computed (being the designing and calculating coordinate) of each key potential reference point according to design or Fabrication parameter, perhaps the measuring-signal of each stress sensing element (or under it signal measurement part) calculates the coordinates computed of each key potential reference point actual measurement respectively when (ii) being subjected to actual touch pressure according to each reference point, and it is located list storage at processor or storer etc., if the coordinates computed and the designing and calculating coordinate of same reference point actual measurement are variant, can replace the storage of designing and calculating coordinate with the coordinates computed of actual measurement, also can replace the coordinates computed storage of original actual measurement with the coordinates computed of actual measurement afterwards, also can calculate the coordinates computed and the storage of this key potential reference point with near the coordinates computed of reference point actual measurement certain key potential reference point;
If the coordinates computed of the designing and calculating coordinate of each key potential reference point or actual measurement is different and different according to the suffered touch pressure of this reference point, can be with each key potential reference point each coordinates computed list storage under various touch pressures when needing;
(v) when touch pad is subjected to touching, according to (ii) obtaining this touch point corresponding calculated coordinate, its coordinates computed with each key potential reference point of storage is compared judgement or simply relatively judgement, find (to be under the corresponding touch pressure when needing) immediate one or several reference point under the corresponding situation, and according to its affiliated or adjacent key position the orientation should be arranged, determine this key position, place, touch point and corresponding input character or information or instruction;
Wherein said simply relatively judgement is meant:
When selected key potential reference point is key position central point, from storage, to find with this touch point coordinates computed in this kind reference point coordinates computed nearestly, this key position, reference point place i.e. this key position, place, touch point,
When selected key potential reference point is key bit boundary or boundary line segment upper left (or lower-left or upper right or bottom right) angle flex point, from storage, find in this kind reference point coordinates computed and be positioned at this touch point coordinates computed upper left (or lower-left or upper right or bottom right) side and nearest apart from this touch point coordinates computed, this key position, reference point place or this reference point bottom right (or upper right or lower-left or upper left) side next-door neighbour key position i.e. this key position, place, touch point
When selected key potential reference point is a left side, key position (or right or up or following) lateral boundaries or boundary line segment mid point, find in this kind reference point coordinates computed to be positioned at side and nearest apart from this touch point coordinates computed, this coordinates computed left side, touch point (or right or up or down) from storage, this key position, reference point place or this reference point right side (or left or down or on) side next-door neighbour key position i.e. this key position, place, touch point;
Under normal conditions, especially the key position is not many especially or sensor output when drifting about not especially severe, and simply relatively judging just can be satisfactory.When needed, also can calculate or determine character or the information or the instruction of its key position, place and representative according to the position (coordinates computed) of several different reference point nearest or nearer or this touch point and the latter's relative position apart from this touch point coordinates computed.
Above-mentioned a left side or the right side are meant that the horizontal ordinate algebraic value of its coordinates computed is less or bigger, and above-mentioned upward or down is meant that the ordinate algebraic value of its coordinates computed is bigger or less.
Said method I both had been applicable to that the surface had the touch pad with the corresponding projection in key position, was applicable to that also surperficial key position does not have the touch pad of projection.
The present invention comprises that also another is used for determining the input information of this touch correspondence or the method (abbreviation method II) of instruction or character when touch pad is subjected to touching, and comprising:
(i) make touch pad within it near side or the edge some (more than 2) diverse location have several direct or indirect support zones that can the suffered touch force of this touch pad of balance, all or part of described support zone or its place support component have (or is exactly) stress sensing element itself, when touch pad was subjected to touching, these sensing elements (or its affiliated signal measurement part) can provide the reflection suffered stress of place support zone (anchorage force) measuring-signal or the data of number change continuously;
When (ii) in the system of touch pad place, being defined in touch pad and being subjected to the touch force value that effectively touches or single touch maximum touch force may value and being in various different range and the touch force position of action point that effectively touches (or the coordinates computed of touch force application point is not simultaneously) pairing customizing messages or instruction or character not simultaneously;
(iii) when touch pad is subjected to touch pressure, the numerical evaluation of each anchorage force (or its measuring-signal) of being measured according to the stress sensing element of each support zone of touch pad or parts (or under it signal measurement part) by the processor of touch pad place system or signal processing goes out their sums (can consider touch pad gravity) i.e. touch force value of balance with it, when touch force value or single touch maximum touch force may value greater than predetermined bottom line value (this touchs is effectively touch) and when being in one of above-mentioned each specialized range, geometric position that distributes according to each support zone of touch pad by processor or signal processing or corresponding coordinate data and the numerical value or the ratio of each anchorage force (or its measuring-signal) of measuring of the stress sensing element of each support zone or parts (or under it signal measurement part) at that time, calculate each anchorage force make a concerted effort (can consider touch pad gravity) position of action point or corresponding coordinates computed, this position or this coordinates computed i.e. touch force position of action point or corresponding coordinates computed at that time;
(iv) touch force value when effectively touching or single maximum touch force may are worth scope of living in and touch force position of action point or corresponding coordinates computed at that time, determine input information or the instruction or the character of this touchs correspondence according to regulation (ii).
Method H is another major progress of the present invention, utilize it on touch pad, to import two or more different information or instruction or character by same position, do not show when too small as touch force, touch force only shows on display than hour character or stroke, just really input of this character when strength is big; For example when the described smooth surface handwriting input of described touch pad, the strength of touch objects is big to a certain degree this character of instruction processorunit having been write again, and recognizer can begin; This method is utilized the difference of strength, also can distinguish the upper case or lower case of same letter, also can distinguish to touch to make cursor show mobile or click cursor, also can indicate relevant apparatus or system enter with the strength of regulation and proofread and correct or adjust duty.
The present invention has also proposed further method (abbreviation method III) on the basis of method I, it also comprises:
Pairing different customizing messages or instruction or character when its touch force value or single maximum touch force may value were in different range when (i) each key position of regulation touch pad was subjected to each effective touch (the touch force value is greater than predetermined bottom line value);
(ii) when touch pad is subjected to effectively touching, processor or signal processing are not only determined the affiliated key position of the coordinates computed of touch force position of action point correspondence, determine also or at first determine that the touch force value (being each support zone anchorage force sum of touch pad) or the single maximum touch force may of this time touch are worth scope of living in, and determine input information or instruction or the character that this touch is corresponding according to (i).
Method III is further developing method I, utilize it can lean on the dynamics of keystroke in same key position, to import different characters (as the number or the literal of mobile phone, capitalization still is lowercase or the like), or distinguish whether to work, show, import or be not in and proofread and correct or the adjustment state.
The invention allows for another method, it is characterized in that also comprising the method (abbreviation method IV) of proofreading and correct or adjusting described key potential reference point coordinates computed based on method I or III:
Be touch pad place system arrangement program, operate to assist following adjustment of realization,
(i) can the operating function button or otherwise make touch pad place system be in the adjustment duty, press relevant desire with desired touch force and adjust key potential reference point or its vicinity, if this system display character display or sign conform to this key position or its reference point, relative program can replace the key potential reference point coordinates computed of actual measurement this moment original coordinates computed storage
(ii) also can operate touch pad or button earlier, this system display is shown with desire adjust character or the sign that the key potential reference point conforms to, press this key potential reference point or its vicinity with desired touch force again, and operating function button or otherwise make this system be in the adjustment duty in advance or simultaneously or subsequently, character that relative program can show the coordinates computed of actual measurement this moment as display or the coordinates computed storage that indicates corresponding key potential reference point.
In actual use, after the coordinates computed adjustment of some reference point accurately, the segment boundary that may find its key position is some deviation still, if the position of pushing this reference point when adjusting a little to skew in the other direction a bit, effect may be better.
From the above description as can be seen, the present invention has utilized according to the ratio of several support zones or the suffered stress of element and has judged the touch surface of contact principle of the position of point with joint efforts, thereby regardless of surface of contact size and shape, the determining positions of point input information with joint efforts, input resolution is high, allow character dense distribution on the touch pad, and be not subjected to the restriction of finger width, the main part separatrix, relative key position, key position or the adjacent part of markup character of the present invention are protruding, even can be with elasticity, improved finger allodynia greatly, be convenient to touch system and improve input speed; The invention allows for reliable easily and effectively touch point method for determining position and correlation-corrected method of adjustment, avoided the possible adverse effect of strain gauge output drift; The present invention distinguishes the method that same position touches pairing different input informations according to the difference of touch force, very helps simplifying keyboard and method of operating.By contrast, the touch of original input technology input resolution depends on the width or the shape of finger or touch objects end surface of contact, has limited miniaturization or the microminiaturization or the input speed of input media.The technology of the present invention is simpler than the prior art structure, only uses several sensors, is more suitable for microminiaturization and reduces cost, and has very outstanding effect.
