This display surface of contact panel 13 can show a screen touch keyboard, and is as shown in Figure 2.Fig. 2 shows the screen touch keyboard according to the embodiment of the invention.When the user imports electronic installation 10 with information such as literal, can adopt mode to refer to input informations with ten as using physical keyboard.
Fig. 3 A～Fig. 3 B shows the process flow diagram according to the input control method of the screen touch keyboard of the embodiment of the invention.Method is can be implemented in the electronic installation of Fig. 1 shown in Fig. 3 A～Fig. 3 B.Wherein, the demonstration appearance attitude of screen touch keyboard can have various variations, is not limited to person shown in Figure 2.
In step S310, on the display surface of an electronic device touch control screen, show a screen touch keyboard (referring to Fig. 2).
Among the step S311, be received on this screen touch keyboard one first and touch incident pairing 1 first and touch information.This first information of touching comprise this first incident of touching begin (touch down) to finish between (touch up) at this screen touch keyboard touch location information, touch temporal information and touch range information.
Among the step S312; Receive and be recorded on this screen touch keyboard one second and touch incident pairing 1 second and touch information, this second information of touching comprises that this second incident of touching begins to the touch location information on this screen touch keyboard between finishing, touches temporal information and touch range information.
In embodiments of the present invention, so-called " incident of touching begins " is expression: when positions such as user's finger or palm touch the multi-point touch screen; And so-called " touch incident finish " is expression: when user's finger or palm leave touch control screen and make when touching releasing (touch up).
That is; User's a certain finger (like forefinger) touches screen (incident of touching begins); Also this forefinger is not being left screen (incident of touching finishes) before, this touches the touch location information of incident electronic installation meeting periodic logging, and touches temporal information with saving as this this writing time.And above-mentioned so-called first and second touches information, comprises that promptly this time incident of touching is beginning between finishing, each writing time touch location that point is recorded, touch the time and touch scope.
When Fig. 4 is presented at a certain some writing time (being referred to as very first time point), touches incident and second corresponding to first and touch the touch location of incident and touch the scope synoptic diagram.When putting for first writing time, record corresponding to first touch incident the scope of touching 41 and corresponding to second touch incident the scope of touching 42.
Among the step S313, according to this first touch information this touch range information, calculate this first touch incident corresponding touch the area size.
In step S314,, judge that this first incident of touching is touched incident for finger or non-finger touches incident according to this result of calculation.When this first incident of touching was judged as this non-finger and touches incident, execution in step S300 ignored this and first touches incident, does not produce a keying input information to this first incident of touching.
For example, can set the area size criteria in advance, dividing in regular turn with the incident of will touching according to the area size of touching scope, (ascending) is divided into: non-ly touch incident, finger touches incident and palm touches incident.Wherein, non-incident and the palm incident of touching of touching is " non-finger touches incident ".Wherein, the finger incident of touching is divided into according to touching area size again touches the bigger thumb of area and touches incident, and touches the less non-thumb of area and touch incident.
Therefore, in step S313 and S314, filter out by finger and touch the incident of touching that (comprising thumb and other four fingers) cause, and ignore area too big (palm touches) or the too little incident of touching of touching.So when receiving an excessive zone or crossing the touching of zonule, can judge this touching and non-keyboard input needed touching (touch down).When the user imports, might be with the position of palm near wrist, the position of wrist or the position of palmar side are placed on the contact surface plate and form the behavior of big area touch.And sometimes possible because of the relation that moves, the slight surface that touches the touching screen perhaps because the relationship detection of hardware sensor arrives trickle touching, and makes system detect the very touching of zonule.And these two kinds of touchings all are not the behavior that meets one user's input, therefore need these two kinds of situations be got rid of outside the keyboard input.
When this first incident of touching is judged as this finger and touches incident; In step S315; First touch this touch location information that information and this second touches information according to this this, calculate this and first touch incident and this second and touch the distance between the scope 41 and 42 of incident.For example, be first to touch incident and this second and touch the distance between the scope 41 and 42 of incident with the minimum distance at scope of touching 41 and 42 edges, like the length a among Fig. 4.
In step S316, whether judge this distance less than a predetermined value, if this distance is less than a predetermined value, execution in step S300 then ignores this and first touches incident, first does not touch incident generation keying input information to this.If this distance is greater than this predetermined value, executive routine A then, further to this first touch incident this first information of touching handle.
Referring to Fig. 3 B; When being judged as this finger, this first incident of touching touches incident; And this first touch that incident and this second touch incident this when touching this distance between the scope greater than this predetermined value; Then start a timer, measure this first incident of touching and begin the incident duration till finish at step S331.
In step S333; Judge this first touch incident incident duration whether surpass a schedule time length; Obtain when this timer measuring this first touch incident incident duration surpass a schedule time during length; Ignore this and first touch incident, do not produce keying input information to this first incident of touching.That is, after this incident of touching has continued one period schedule time, just judge that this incident of touching is that the user is placed on finger on the keyboard and has a rest.
Obtain when this timer measuring this first touch incident incident duration surpass this during length, execution in step S335 schedule time.
In step S335, judge when this first incident of touching finishes that pairing this touch location information was identical when whether pairing this touch location information began with this first incident of touching.
If pairing this touch location information was inequality when pairing this touch location information began with this first incident of touching when this first incident of touching finished; Execution in step S300 then; Ignore this and first touch incident, do not produce keying input information to this first incident of touching.If pairing this touch location information was identical when pairing this touch location information began with this first incident of touching when this first incident of touching finished, then execution in step S36 produces keying input information to this first incident of touching.
According to present embodiment, judge in step S335 whether pairing this touch location information pointed to the same key position on this multi-point touch screen when pairing this touch location information began with this first incident of touching when this first incident of touching finished.
Touch second of incident to second and touch information, also carry out as above-mentioned step S313～step S317 and S331～S335, judge whether and to produce keying input information to this second incident of touching.In the present embodiment; In step S313 and S314, calculate this second touch information the scope of touching 42 touch area, and second incident of touching be judged as palm touch incident (that is non-finger touches incident) according to the area that touches that touches scope 42; Therefore; Incident execution in step S300 second touches to this in system, ignores this and second touches incident, and do not produce a keying input information to this second incident of touching.
When a new touch event takes place, also to itself and original touching zone be carried out above-mentioned judgement.
For example, referring to Fig. 5, when Fig. 5 is presented at another some writing time (being referred to as second time point), the touch location of the incident of touching on the screen touch keyboard and touch the scope synoptic diagram.When second time point; First incident of touching finishes (user leaves contact panel with finger); And the 2nd incident of touching still continues (user's left hand palm root still is seated on the contact panel), and contact panel receives one the 3rd in addition and touches incident.Therefore, on Fig. 5, can see, when putting for second writing time, record corresponding to second touch incident the scope of touching 42 and corresponding to the 3rd touch incident the scope of touching 43.
Touch the 3rd of incident to the 3rd and touch information, also carry out as above-mentioned step S313～step S317 and S331～S335, judge whether and to produce keying input information to the 3rd incident of touching.In the present embodiment, in step S313 and S314, calculate the 3rd touch information the scope of touching 43 touch area, and the 3rd incident of touching be judged as finger touch incident according to the area that touches that touches scope 43; Again in step S315 and step S316; Calculating the 3rd touches incident and this second and touches the distance between the scope 42 and 43 of incident; And judge and learn this distance that therefore, incident execution in step S300 touches to the 3rd in system less than above-mentioned predetermined value; Ignore the 3rd and touch incident, and do not produce a keying input information to the 3rd incident of touching.
Above-mentioned each judges that the input control for software keyboard all has different help, is not must whole condition judgment all be implemented on the software keyboard.Different and make up different judgment mechanisms and just can make the input of software keyboard control the use habit that meets the user to the purpose of software keyboard.
Though the present invention discloses as above with preferred embodiment; Right its is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little change and retouching, so protection scope of the present invention is as the criterion when looking the claim scope person of defining.
