2 is a flowchart illustrating a process of controlling sensitivity of a keypad displayed on a screen according to an exemplary embodiment of the present invention.

Hereinafter, the process of controlling the sensitivity of the keypad displayed on the screen according to an embodiment of the present invention will be described in detail with reference to FIG.

In addition, the electronic device 100 may store the time at which the input was sensed. These inputs may be touch-based inputs or hovering inputs. The at least one input may be used to form an area recognized per key.

The electronic device 100 may determine 230 the boundary for sensing the input to the key using the stored at least one location information. The electronic device 100 may determine or form the boundary by calculating at least one stored location information statistically. The statistical method may include at least one of an average, a standard deviation, and a variance of a coordinate value of a point at which an input is sensed. The electronic device 100 may calculate an average of points where at least one input is detected for each key and form at least one area for recognizing the keys using the calculated average value. The electronic device 100 calculates an average of positional information (e.g., coordinate values) of an input (e.g., touch or hovering) input to select each key on the keypad, A boundary for dividing the image into a plurality of regions may be formed according to a predetermined distance around a point corresponding to the calculated average value.

The electronic device 100 can apply different sensitivities to the respective regions in a plurality of regions divided for each key. The electronic device 100 can increase the sensitivity of the area within the boundary for each key and reduce the sensitivity of the area outside the boundary. For example, if there are a plurality of regions formed in each key, the sensitivity of the innermost region can be increased to the most sensitive, the sensitivity of the outermost region can be reduced to the most insensitive, . The electronic device 100 can apply the highest sensitivity to the nearest region around the point corresponding to the average value in each of the plurality of regions and apply the lowest sensitivity to the farthest region.

3 is an exemplary view showing a keypad displayed on a screen according to an embodiment of the present invention.

Referring to FIG. 3, a keypad on a screen according to an embodiment of the present invention may include a plurality of keys. Each key may be displayed differently depending on the country or type of keypad, and the position where the key is displayed may be adjusted according to the user's taste. When the keypad 310 displays alphabets and numbers, alphabets and numbers may be assigned to each key, and when an arbitrary key is selected, the electronic device 100 may sense the selected key. For example, the first key 310-1 is assigned the number '1', the second key 310-2 is assigned the alphabet 'ABC' and the number '2', and the third key 310 -3) can be assigned the alphabet 'DEF' and the number '3'. The keypad 310 may include a plurality of (N) keys. Each key is allocated a certain area, and when an input is detected in the area, it can be determined that the key is selected. For example, when the user selects (330) the first key 310-1 using the hand 320, the electronic device 100 may determine to select the number '1'. The user can select any key on the keypad 310 through his or her left hand or right finger.

FIG. 4A is a view illustrating a boundary according to sensitivity of each key when a key of a keypad is input with a left hand in a state where the keypad is held by a left hand according to an embodiment of the present invention. FIG. FIG. 4C is a view showing a boundary according to the sensitivity of the keypad according to the embodiment of the present invention when the key of the keypad is inputted with the right finger while the keypad according to the present invention is gripped with the right hand. Fig.

4A to 4C are diagrams showing positions of the same sensitivity for each screen or each key by a dotted line. In FIG. 4A to FIG. 4C, the portions having the highest sensitivity for each key are displayed as one, Or may be generated outside of the key.

Referring to FIG. 4A, each key formed on the keypad 410 may be formed with a boundary indicating the degree of sensitivity through a plurality of touches of the left hand or hovering input. The first key 310-1 is assigned the number '1', the second key 310-2 is assigned the alphabet ABC and the number 2, and the third key 310-3 is assigned the number ' The alphabet 'DEF' and the number '3' can be assigned. The keypad 410 may include a plurality of keys. Each of the keys may have a plurality of boundaries according to the position information of the input point, and each of the boundaries may be classified according to the sensitivity for determining the key input. For example, in the first key 310-1, the first region 414 has the highest sensitivity. In the second region 413, the region except for the first region 414 has a sensitivity lower than that of the first region 414, The sensitivity of the third region 412 is lower than that of the second region 413 and the sensitivity of the third region 412 is lower than that of the second region 413, The region other than the third region 412 is a region whose sensitivity is lower than that of the third region 413. As described above, the sensitivity decreases toward the outside in the first region 414. Likewise, in the third key 310-3, the first region 424 is the highest sensitivity region, and the second region 423 excluding the first region 424 has sensitivity higher than the first region 424 The sensitivity of the third region 422 excluding the second region 423 is lower than that of the second region 423 and the sensitivity of the third region 423 is lower than the sensitivity of the third region 421, The region other than the region 422 is a region whose sensitivity is lower than the sensitivity of the third region 423. As described above, the sensitivity decreases toward the outside in the first region 424. According to the present invention, by dividing the boundaries having different sensitivities by each of these keys, erroneous input can be removed from the user input, or at least the number of erroneous inputs can be reduced. For example, when an input is detected in the fourth area 411 of the first key 310-1, the electronic device 100 normally performs an operation when the first key 310-1 is input , If the input is detected outside the fourth area 411, the electronic device 100 may determine that no input is input. 4A, when a key of the keypad is input with the left hand in a state that the keypad is held by the left hand, the boundary of the key formed on the left of the keypad 410 can be shifted to the right, The boundary of the key formed on the left side can be shifted to the left.

Referring to FIG. 4B, each key formed on the keypad 410 may be formed with a boundary indicating the degree of sensitivity through a plurality of touches of the right finger or input by hovering. The first key 310-1 is assigned the number '1', the second key 310-2 is assigned the alphabet ABC and the number 2, and the third key 310-3 is assigned the number ' The alphabet 'DEF' and the number '3' can be assigned. The keypad 410 may include a plurality of keys. Each of the keys may have a plurality of boundaries according to the position information of the input point, and each of the boundaries may be classified according to the sensitivity for determining the key input. For example, in the first key 310-1, the first area 433 has the highest sensitivity. In the second area 432, the area excluding the first area 433 has sensitivity, The sensitivity of the second area 432 is lower than that of the second area 433 and the sensitivity of the area of the third area 431 excluding the second area 432 is lower than that of the second area 432. As described above, the sensitivity decreases toward the outside in the first region 433. 4B, when a key of the keypad is input with the right finger while the keypad is held by the right hand, the boundary of the key formed on the left of the keypad 410 may be shifted to the right, The boundary of the key formed on the left side can be shifted to the left.

Referring to FIG. 4C, a boundary according to the same sensitivity may be formed on the keypad. Different sensitivities can be set according to the boundaries formed on the keypad. The electronic device 100 may process or ignore the input by touch or hovering input to select a key through this sensitivity. The input may be processed or ignored by increasing the sensitivity at the center of the key at a plurality of boundaries formed in each key and decreasing the sensitivity as it goes out of the center. According to the touch input habit of the user, when a plurality of touches are detected at a position outside the area formed by the keys, a boundary can be formed at the point where the touch is detected. The electronic device 100 may determine that the key is an input for selecting a key when a plurality of touched points are detected at a position outside a region formed by the key.

The intervals for storing the information on the touch positions of the respective keys can be changed according to the input or the selection of the user, and the key dominant positioning intervals can be determined each time or intermittently according to the stored input positions.

If the input is to select the key (550), the electronic device 100 may perform a function corresponding to the key (560). If the coordinate value of the point at which the input is sensed exists at a position not exceeding the boundary, the input may be determined as an input for selecting the key. Also, when the coordinate value of the point at which the input is sensed does not deviate from a predetermined threshold value about a point corresponding to the calculated average value, the input may be determined as an input for selecting the key.

If the input is not an input for selecting the key in step 550, the electronic device 100 may ignore the sensed input (step 570). When the input is sensed, the electronic device 100 can ignore the input when the coordinate value of the point at which the input is sensed is located at a position outside the boundary. Alternatively, if the coordinate value of the point at which the input is sensed deviates from a predetermined threshold around a point corresponding to the calculated average value, the electronic device 100 can ignore the input.
