Abstract

An example electronic device may include a touch sensor and a processor. Based on a touch input at a plurality of contact points contacted on the touch sensor, the processor can identify the distance between the plurality of contact points and the center point of the plurality of contact points. Based on a speed of the center point due to the movement of the contact points, the processor can obtain a probability that the touch input corresponds to a first designated gesture associated with the distance and a probability that the touch input corresponds to a second designated gesture associated with the movement of the center point. The processor can change at least one of the distance or the center point based on the probabilities.

First claim

What is claimed is:

1 . An electronic device comprising:
a touch sensor, and at least one processor comprising processing circuitry, and memory comprising one or more storage media storing instructions, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
based on a touch input at a plurality of contact points contacted on the touch sensor, identify a distance between the plurality of contact points, and a center point of the plurality of contact points,
based on a speed of the center point by a movement of the contact points, obtain probabilities in which the touch input corresponds to each of a first specified gesture related to the distance and a second specified gesture related to a movement of the center point, and
based on the probabilities, change at least one of the distance or the center point.

2 . The electronic device of claim 1 ,
wherein instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
change the center point of the distance or the center point in a state in which the touch input being related to the first specified gesture is identified based on the probabilities.

3 . The electronic device of claim 2 ,
wherein instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
based on the probabilities being inversely proportional to the speed of the center point, identify that the touch input is related to the first specified gesture.

4 . The electronic device of claim 1 ,
wherein instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
change the distance of the distance or the center point in another state in which the touch input being related to the second specified gesture is identified based on the probabilities.

5 . The electronic device of claim 4 ,
wherein instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
based on the probabilities being proportional to the speed of the center point, identify that the touch input is related to the second specified gesture.

6 . The electronic device of claim 1 ,
wherein instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
change the distance to be below a distance between the plurality of contact points.

7 . The electronic device of claim 1 ,
wherein instructions, when executed by the at least one processor individually or collectively, cause the electronic device to: identify the movement of the center point by the movement of the contact points, and based on the identified movement of the center point, change the center point to be below a distance in which the center point is moved.

8 . The electronic device of claim 1 ,
wherein instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
based on a specified time interval, identify the movement of the contact points.

9 . The electronic device of claim 1 ,
wherein instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
based on changing at least one of the distance or the center point, execute an event related to at least one of the first specified gesture or the second specified gesture, based on an application executed by the processor.

10 . The electronic device of claim 1 ,
wherein instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
based on a size of a touch sensing area based on the touch sensor, change at least one of the distance or the center point.

11 . A method of an electronic device, comprising:
based on a touch input at a plurality of contact points contacted on a touch sensor, identifying a distance between the plurality of contact points, and a center point of the plurality of contact points, based on a speed of the center point by a movement of the contact points, obtaining probabilities in which the touch input corresponds to each of a first specified gesture related to the distance and a second specified gesture related to a movement of the center point, and based on the probabilities, changing at least one of the distance or the center point.

12 . The method of claim 11 , comprising:
changing the center point of the distance or the center point in a state in which the touch input being related to the first specified gesture is identified based on the probabilities.

13 . The method of claim 12 , comprising:
based on the probabilities being inversely proportional to the speed of the center point, identifying that the touch input is related to the first specified gesture.

14 . The method of claim 11 , comprising:
changing the distance of the distance or the center point in another state in which the touch input being related to the second specified gesture is identified based on the probabilities.

15 . The method of claim 14 , comprising:
based on the probabilities being proportional to the speed of the center point, identifying that the touch input is related to the second specified gesture.

16 . The method of claim 11 , comprising:
changing the distance to be below a distance between the plurality of contact points.

17 . The method of claim 11 , comprising:
identifying the movement of the center point by the movement of the contact points, and based on the identified movement of the center point, changing the center point to be below a distance in which the center point is moved.

18 . The method of claim 11 , comprising:
based on a specified time interval, identifying the movement of the contact points.

19 . The method of claim 11 , comprising:
based on changing at least one of the distance or the center point, executing an event related to at least one of the first specified gesture or the second specified gesture, based on an application executed by a processor.

20 . The method of claim 11 , comprising:
based on a size of a touch sensing area based on the touch sensor, changing at least one of the distance or the center point.
