Embodiment
Hereinafter, describe the preferred embodiments of the present invention in detail with reference to accompanying drawing.Note, in this instructions and accompanying drawing, have substantially the same step and represent with identical Reference numeral with element, and will be omitted the repetition of explanation of these steps and element.
In following examples of the present invention, the concrete form of electronic equipment can include but not limited to portable computer, tablet computer, mobile phone, personal digital assistant, portable music player etc.In the electronic equipment of the embodiment of the present invention, can comprise for example touch sensing unit of touch-screen, touch panel and so on.
Fig. 1 has described the process flow diagram that judgement according to an embodiment of the invention touches the method 100 of input.Below, with reference to Fig. 1, method according to the alternative of the embodiment of the present invention is described.The method 100 that judgement touches input can be used for above-mentioned electronic equipment.
As shown in Figure 1, in step S101, when operating body being detected in the touch-sensitive area that is initially at electronic equipment, the first contact area parameter of the first area that the acquisition operating body contacts with touch-sensitive area.Then, in step S102, through after predetermined time interval, the second contact area parameter of the second area that the acquisition operating body contacts with touch-sensitive area.
For example, in the electronic equipment of embodiment, can comprise for example touch sensing unit of touch-screen, touch panel and so on, the touch of carrying out to detect operating body in touching induction region.Touch sensing unit can comprise, for example, and the touch detecting element of pressure-sensitive, static touch pad or capacitance contact board and so on.According to step S101, when touch sensing unit detects when operating body occurring in touch-sensitive area, the first contact area parameter of the first area when obtaining operating body that touch sensing unit detects and initially contacting with touch-sensitive area.Then, according to step S102, through after predetermined time interval, obtain the second contact area parameter of the second area that operating body that this moment, touch sensing unit detected contacts with touch-sensitive area.
For example the operating body of finger and so on and the contact area of touch-sensitive area may be zones in irregular shape.Fig. 2 A shows an example according to this aspect, the schematic diagram that finger contacts with touch-sensitive area.Fig. 2 B shows and is shown in when carrying out touch operation in touch-sensitive area as Fig. 2 A when finger, the schematic diagram of the contact area 210 that touch sensing unit detects.As shown in Fig. 2 B, touch-screen 200 is made of the array that a plurality of subelements form, and the area of each subelement is substantially equal.According to an example of the present invention, in step S101 and step S102, the number of the subelement that can cover according to contact area 210 determines that contact area that finger contacts with touch-sensitive area is as the contact area parameter.
According to another example of the present invention, can be with the approximate circle that is considered as of finger and the contact area of touch-sensitive area, thereby, can be with the geometric center of contact area to the maximum distance on the border of contact area as this circular radius, and in step S101 and step S102, the radius of circle that will be corresponding with contact area is as the contact area parameter.Replacedly, can obtain the circumcircle of contact area, in step S101 and step S102, and with circumscribed radius as the contact area parameter.
In step S103, determine the ratio between the first contact area parameter and the second contact area parameter.As shown in the example in Fig. 2 A and Fig. 2 B, the number of the subelement that can cover according to contact area 210 in step S101 and step S102 is determined the contact area that finger contacts with touch-sensitive area.Therefore, in step S103, can be with the first contact area of obtaining in step S101 divided by the second contact area that obtains in step S102, to determine the ratio between the first contact area parameter and the second contact area parameter.
In addition, will be corresponding to the radius of the circle of contact area during as the contact area parameter, in step S103, can determine ratio between the first contact area parameter and the second contact area parameter according to the radius of first circle corresponding with the first area with the radius ratio of the second circle corresponding to second area.
Ratio and first threshold between the first contact area parameter and the second contact area parameter can be compared.Fig. 3 A shows an example according to this aspect, the schematic diagram of first area 310 and second area 320 when the user carries out the first touch operation.Fig. 3 B shows an example according to this aspect, the schematic diagram of first area 310 ' and second area 320 ' when the user carries out the second touch operation.According to an example of the present invention, the first touch operation can be for example to slide to touch the mobile touch input of input and so on, and the second touch operation can be the touch operation of carrying out on the fixed position.
As shown in Figure 3A, that for example slides in touch-sensitive area 300 as the user and touch input is mobile when touching input, and for example the change amount of the area that contacts with touch-screen of the operating body of user's finger and so on is less.That is to say, when the touch on the fixed position is inputted, the first contact area parameter when operating body begins to contact with touch-sensitive area is less with change amount between the second contact area parameter that contacts with touch-sensitive area through operating body after a time interval (for example in the present embodiment for predetermined time interval), that is, the ratio between the first contact area parameter and the second contact area parameter is larger.
As shown in Fig. 3 B, when the touch on the fixed position of family in touch-sensitive area 300 was inputted, the operating body of user's finger and so on was pressed touch-screen, and the change amount of the area that contacts with touch-screen is larger.That is to say, when the touch on the fixed position is inputted, the first contact area parameter when operating body begins to contact with touch-sensitive area is less, and the second contact area parameter that begins to contact with touch-sensitive area through operating body after a time interval (for example being in the present embodiment predetermined time interval) is larger, that is, the ratio between the first contact area parameter and the second contact area parameter is less.
Therefore, as shown in Figure 1, in step S104, during greater than first threshold, determine that operating body carries out the first touch operation when the ratio between the first contact area parameter and the second contact area parameter.As mentioned above, according to an example of the present invention, the first touch operation can be that for example, sliding touches the mobile touch input of input and so on.
Touch the method for inputting by the judgement in the invention described above embodiment, do not need to lower electronic equipment and also can distinguish exactly for the sensitivity that the touch input of sliding responds slide touch input and the touch operation on the fixed position.In addition, touch the method for input in the judgement of the present embodiment, carry out for the judgement that touches input in the same time the ratio of contact area parameter not owing to pointing by the user with equipment, rather than for all users, identical input response sensitivity is set, therefore can reduce the time of its wait-for-response for the little user of finger and equipment contact area, and for the large user of finger and equipment contact area, electronic equipment can detect the type that it touches input exactly.
In addition, as mentioned above, during less than first threshold, the user may carry out the touch operation on the fixed position when the ratio between the first contact area parameter and the second contact area parameter, for example clicks, double-clicks or long by operation.Therefore, according to an example of the present invention, the method described in Fig. 1 also can comprise: during less than first threshold, obtain the center of first area when the ratio between the first contact area parameter and the second contact area parameter; And the processing unit that the center of first area is sent to electronic equipment.
In addition, in order further to determine to carry out the type of touch operation on the fixed position, after the center with the first area is sent to the processing unit of electronic equipment, method shown in Fig. 1 also can comprise: when the odds ratio between described the first contact area parameter and described the second contact area parameter during less than first threshold, with described predetermined time interval, the contact area between described operating body and described touch-sensitive area and the center of described contact area are sampled, until determine that according to sampled value described contact area reduces; When within a predetermined period of time, when the contact area between described operating body and described touch-sensitive area reduces, determine that described operating body carries out the second touch operation.According to an example of the present invention, the second touch operation can be, for example, and clicking operation.
In addition, according to another example of the present invention, when definite operating body carries out the second touch operation, and when operating body being detected and leaving touch-sensitive area, processing unit responds according to the center of first area.That is to say, processing unit responds according to the center that is initially at the first area that operating body contacts with touch-sensitive area when operating body being detected in the touch-sensitive area of electronic equipment, thereby has the problem of error before the touch point that the touch point that the electronic equipment of having avoided the contact area change due to operating body in the process of pressing and touch-sensitive area to cause is identified and user wish.Improve the accuracy of touch operation identification.
On the other hand, when within a predetermined period of time, contact area between operating body and touch-sensitive area does not reduce, and the distance between the center of the contact area that obtains of twice adjacent sampling determines that operating body carries out the 3rd touch operation during less than Second Threshold.According to an example of the present invention, the 3rd touch operation can be, and is for example, long by operation.
In addition, according to another example of the present invention, when definite operating body carried out the 3rd touch operation, processing unit responded according to the center of first area.That is to say, processing unit responds according to the center that is initially at the first area that operating body contacts with touch-sensitive area when operating body being detected in the touch-sensitive area of electronic equipment, thereby has the problem of error before the touch point that the touch point that the electronic equipment of having avoided the contact area change due to operating body in the process of pressing and touch-sensitive area to cause is identified and user wish.Improve the accuracy of touch operation identification.
On the other hand, when within a predetermined period of time, contact area between operating body and touch-sensitive area does not reduce, and the distance between the center of the contact area that obtains of twice adjacent sampling determines that operating body carries out the first touch operation during greater than Second Threshold.According to an example of the present invention, the first touch operation can be, for example, and slide.
When definite operating body carried out the first touch operation, the center of the contact area that obtains sample at every turn sent to processing unit.And processing unit responds according to the center of the contact area that each sampling obtains, in order to generate the order corresponding to the first touch operation of user.
Fig. 4 is the process flow diagram of having described the method 400 of judgement touch input according to another embodiment of the present invention.Below, with reference to Fig. 4, method according to the alternative of the embodiment of the present invention is described.The method 400 that judgement touches input can be used for above-mentioned electronic equipment.
As shown in Figure 4, in step S401, when operating body being detected in the touch-sensitive area that is initially at electronic equipment, the first contact area parameter of the first area that the acquisition operating body contacts with touch-sensitive area.Then, in step S402, through after predetermined time interval, the second contact area parameter of the second area that the acquisition operating body contacts with touch-sensitive area.
For example, in the electronic equipment of embodiment, can comprise for example touch sensing unit of touch-screen, touch panel and so on, the touch of carrying out to detect operating body in touching induction region.Touch sensing unit can comprise, for example, and the touch detecting element of pressure-sensitive, static touch pad or capacitance contact board and so on.According to step S401, when touch sensing unit detects when operating body occurring in touch-sensitive area, the first contact area parameter of the first area when obtaining operating body that touch sensing unit detects and initially contacting with touch-sensitive area.Then, according to step S402, through after predetermined time interval, obtain the second contact area parameter of the second area that operating body that this moment, touch sensing unit detected contacts with touch-sensitive area.As mentioned above, as shown in the example in Fig. 2 A and Fig. 2 B, the contact area parameter can be, the contact area that the number of the subelement that covers according to contact area 210 obtains.Replacedly, will be corresponding to the radius of the circle of contact area during as the contact area parameter, the contact area parameter can also be the radius of the circle corresponding with contact area.
In step S403, determine the ratio between the first contact area parameter and the second contact area parameter.As shown in the example in Fig. 2 A and Fig. 2 B, the number of the subelement that can cover according to contact area 210 in step S401 and step S402 is determined the contact area that finger contacts with touch-sensitive area.Therefore, in step S403, can be with the first contact area of obtaining in step S401 divided by the second contact area that obtains in step S402, to determine the ratio between the first contact area parameter and the second contact area parameter.
In addition, will be corresponding to the radius of the circle of contact area during as the contact area parameter, in step S403, can determine ratio between the first contact area parameter and the second contact area parameter according to the radius of first circle corresponding with the first area with the radius ratio of the second circle corresponding to second area.
Ratio and first threshold between the first contact area parameter and the second contact area parameter can be compared.As mentioned above, when the user for example slide and touch input mobile when touching input, for example the change amount of the area that contacts with touch-screen of the operating body of user's finger and so on is less.That is to say, when the touch on the fixed position is inputted, the first contact area parameter when operating body begins to contact with touch-sensitive area is less with change amount between the second contact area parameter that contacts with touch-sensitive area through operating body after a time interval (for example in the present embodiment for predetermined time interval), that is, the ratio between the first contact area parameter and the second contact area parameter is larger.And the touch on fixed position when input, the operating body of user's finger and so on is pressed touch-screen, and the change amount of the area that contacts with touch-screen is larger.That is to say, when the touch on the fixed position is inputted, the first contact area parameter when operating body begins to contact with touch-sensitive area is less, and the second contact area parameter that begins to contact with touch-sensitive area through operating body after a time interval (for example being in the present embodiment predetermined time interval) is larger, that is, the ratio between the first contact area parameter and the second contact area parameter is less.Therefore, as shown in Figure 4, in step S404, during greater than first threshold, determine that operating body carries out slide when the ratio between the first contact area parameter and the second contact area parameter in touch-sensitive area.And during greater than first threshold, determine that operating body carries out pressing operation when the ratio between the first contact area parameter and the second contact area parameter in touch-sensitive area.According to an example of the present invention, pressing operation can comprise single-click operation, double click operation and long by operation etc.
Touch the method for inputting by the judgement in the invention described above embodiment, do not need to lower electronic equipment and also can distinguish exactly for the sensitivity that the touch input of sliding responds slide touch input and the touch operation on the fixed position.In addition, touch the method for input in the judgement of the present embodiment, carry out for the judgement that touches input in the same time the ratio of contact area parameter not owing to pointing by the user with equipment, rather than for all users, identical input response sensitivity is set, therefore can reduce the time of its wait-for-response for the little user of finger and equipment contact area, and for the large user of finger and equipment contact area, electronic equipment can detect the type that it touches input exactly.
Below, the electronic equipment of embodiments of the invention is described with reference to Fig. 5.Fig. 5 shows the demonstrative structure block diagram of electronic equipment 500 according to an embodiment of the invention.As shown in Figure 5, the electronic equipment 500 of the judgement of the present embodiment touch input comprises area detecting unit 510, ratio determining unit 520 and operation determination unit 530.The unit of electronic equipment 500 is carried out each step/function of the method for the alternative in above-mentioned Fig. 1, and is therefore succinct in order to describe, and no longer specifically describes.
For example, when operating body being detected in the touch-sensitive area that is initially at electronic equipment, area detecting unit 510 can obtain the first contact area parameter of the first area that operating body contacts with touch-sensitive area, and through after predetermined time interval, can obtain the second contact area parameter of the second area that operating body contacts with touch-sensitive area.
For example, in the electronic equipment of embodiment, can comprise for example touch sensing unit of touch-screen, touch panel and so on, the touch of carrying out to detect operating body in touching induction region.Touch sensing unit can comprise, for example, and the touch detecting element of pressure-sensitive, static touch pad or capacitance contact board and so on.When touch sensing unit detects when operating body occurring in touch-sensitive area, the first contact area parameter of the first area the when operating body that the touch sensing unit that can obtain area detecting unit 510 detects initially contacts with touch-sensitive area, then through after predetermined time interval, area detecting unit 510 can obtain the second contact area parameter of the second area that operating body that this moment, touch sensing unit detected contacts with touch-sensitive area.
As mentioned above, in the example shown in 2B, the contact area parameter can be the contact area that the number of the subelement that covers according to contact area 210 obtains.Replacedly, will be corresponding to the radius of the circle of contact area during as the contact area parameter, the contact area parameter can also be the radius of the circle corresponding with contact area.
Ratio determining unit 520 can be determined the ratio between described the first contact area parameter and described the second contact area parameter.As shown in the example in Fig. 2 A and Fig. 2 B, the number of the subelement that ratio determining unit 520 can cover according to contact area 210 is determined the contact area that finger contacts with touch-sensitive area.Therefore, ratio determining unit 520 can be with the first surface of contact of obtaining when operating body being detected in the touch-sensitive area that is initially at described electronic equipment divided by the second contact area through obtaining after predetermined time interval, to determine the ratio between the first contact area parameter and the second contact area parameter.
In addition, will be corresponding to the radius of the circle of contact area during as the contact area parameter, ratio determining unit 520 can be determined ratio between the first contact area parameter and the second contact area parameter according to the radius of first circle corresponding with the first area with the radius ratio of the second circle corresponding to second area.
Ratio and first threshold between the first contact area parameter and the second contact area parameter can be compared.As shown in Figure 3A, when the user for example slide and touch input mobile when touching input, for example the change amount of the area that contacts with touch-screen of the operating body of user's finger and so on is less.That is to say, when the touch on the fixed position is inputted, the first contact area parameter when operating body begins to contact with touch-sensitive area is less with change amount between the second contact area parameter that contacts with touch-sensitive area through operating body after a time interval (for example in the present embodiment for predetermined time interval), that is, the ratio between the first contact area parameter and the second contact area parameter is larger.
And as shown in Fig. 3 B, when the touch on the fixed position was inputted, the operating body of user's finger and so on was pressed touch-screen, and the change amount of the area that contacts with touch-screen is larger.That is to say, when the touch on the fixed position is inputted, the first contact area parameter when operating body begins to contact with touch-sensitive area is less, and the second contact area parameter that begins to contact with touch-sensitive area through operating body after a time interval (for example being in the present embodiment predetermined time interval) is larger, that is, the ratio between the first contact area parameter and the second contact area parameter is less.
Therefore, during greater than first threshold, operation determination unit 530 determines that operating body carries out the first touch operation when the ratio between the first contact area parameter and the second contact area parameter.As mentioned above, according to an example of the present invention, the first touch operation can be that for example, sliding touches the mobile touch input of input and so on.
By the electronic equipment in the invention described above embodiment, do not need to lower electronic equipment and can distinguish exactly for the sensitivity that the touch input of sliding responds slide touch input and the touch operation on the fixed position yet.In addition, touch the method for input in the judgement of the present embodiment, carry out for the judgement that touches input in the same time the ratio of contact area parameter not owing to pointing by the user with equipment, rather than for all users, identical input response sensitivity is set, therefore can reduce the time of its wait-for-response for the little user of finger and equipment contact area, and for the large user of finger and equipment contact area, electronic equipment can detect the type that it touches input exactly.
In addition, as mentioned above, during less than first threshold, the user may carry out the touch operation on the fixed position when the ratio between the first contact area parameter and the second contact area parameter, for example clicks, double-clicks or long by operation.Therefore, according to an example of the present invention, electronic equipment 500 also can comprise position acquisition unit and processing unit (not shown).When the ratio between the first contact area parameter and the second contact area parameter during less than first threshold, the position acquisition unit can obtain the center of first area, and the center of first area is sent to the processing unit of electronic equipment.
In addition, in order further to determine to carry out the type of touch operation on the fixed position, when the odds ratio between described the first contact area parameter and described the second contact area parameter during less than first threshold, after the center with the first area is sent to the processing unit of electronic equipment, can also sample to the contact area between described operating body and described touch-sensitive area and the center of described contact area by described predetermined time interval in area detecting unit and described position acquisition unit, until determine that according to sampled value described contact area reduces.When within a predetermined period of time, when the contact area between described operating body and described touch-sensitive area reduced, operation determination unit can determine that also described operating body carries out the second touch operation.According to an example of the present invention, the second touch operation can be, for example, and clicking operation.
In addition, according to another example of the present invention, when definite operating body carries out the second touch operation, and when operating body being detected and leaving touch-sensitive area, processing unit responds according to the center of first area.That is to say, processing unit responds according to the center that is initially at the first area that operating body contacts with touch-sensitive area when operating body being detected in the touch-sensitive area of electronic equipment, thereby has the problem of error before the touch point that the touch point that the electronic equipment of having avoided the contact area change due to operating body in the process of pressing and touch-sensitive area to cause is identified and user wish.Improve the accuracy of touch operation identification.
On the other hand, when within a predetermined period of time, contact area between operating body and touch-sensitive area does not reduce, and the distance between the center of the contact area that obtains of twice adjacent sampling is during less than Second Threshold, and operation determination unit can determine that also operating body carries out the 3rd touch operation.According to an example of the present invention, the 3rd touch operation can be, and is for example, long by operation.
In addition, according to another example of the present invention, when definite operating body carried out the 3rd touch operation, processing unit responded according to the center of first area.That is to say, processing unit responds according to the center that is initially at the first area that operating body contacts with touch-sensitive area when operating body being detected in the touch-sensitive area of electronic equipment, thereby has the problem of error before the touch point that the touch point that the electronic equipment of having avoided the contact area change due to operating body in the process of pressing and touch-sensitive area to cause is identified and user wish.Improve the accuracy of touch operation identification.
On the other hand, when within a predetermined period of time, contact area between operating body and touch-sensitive area does not reduce, and the distance between the center of the contact area that twice adjacent sampling obtains is during greater than Second Threshold, and operation determination unit can determine that also operating body carries out the first touch operation.According to an example of the present invention, the first touch operation can be, for example, and slide.
When definite operating body carried out the first touch operation, the center of the contact area that obtains sample at every turn sent to processing unit.And processing unit responds according to the center of the contact area that each sampling obtains, in order to generate the order corresponding to the first touch operation of user.
Below, the electronic equipment of embodiments of the invention is described with reference to Fig. 6.Fig. 6 shows the demonstrative structure block diagram of electronic equipment 600 according to an embodiment of the invention.As shown in Figure 6, the equipment 600 of the present embodiment comprises area detecting unit 610, ratio determining unit 620 and operation determination unit 630.The unit of the electronic equipment 600 of judgement touch input is carried out each step/function of the method for the alternative in above-mentioned Fig. 4, and is therefore succinct in order to describe, and no longer specifically describes.As shown in Figure 6, when operating body being detected in the touch-sensitive area that is initially at electronic equipment, area detecting unit 610 can obtain the first contact area parameter of the first area that operating body contacts with touch-sensitive area.Then, through after predetermined time interval, the area detecting unit can obtain the second contact area parameter of the second area that operating body contacts with touch-sensitive area.
