In the example of FIG. 3 , the threshold value 305 of the touch intensity value set for the touch screen 205 may be 215. In the case of the first user and the second user, when the touch screen 205 is touched with an area of 40 or more, the electronic device 101 can recognize the touch input, but the third user touches the touch screen with an area of 55 ( Since the touch intensity value obtained by step 205 does not exceed the threshold value of 215, the electronic device 101 may not recognize the third user's touch input.

When user authentication is successful in operation 405 , in operation 410 , the electronic device 101 may obtain a touch intensity value of each of a plurality of touch inputs through the touch screen 205 .

Also, in operation 405, the electronic device 101 may acquire area values of each of the plurality of touch inputs through the fingerprint sensor. For example, the electronic device 101 may obtain a touch area value from a fingerprint image acquired through a fingerprint sensor or estimate a touch area value from a major axis and a minor axis of a touch input obtained through a fingerprint sensor.

In operation 415, the electronic device 101 may determine a target threshold value of the touch intensity value based on the acquired touch intensity value and the acquired touch area value.

In an embodiment, the electronic device 101 may determine a target threshold of touch intensity values of a plurality of touch inputs based on touch intensity values and touch area values of the plurality of touch inputs.

In an embodiment, the electronic device 101 may determine an average value of touch intensity values of a plurality of touch inputs as a target threshold value of touch intensity values. In an embodiment, the electronic device 101 sets an average value of the remaining values excluding at least one upper value and at least one lower value among touch intensity values of a plurality of touch inputs as a target threshold value in order to improve suitability of the target threshold value. value can be determined. For example, when the electronic device 101 determines the target threshold based on touch intensity values for 100 touch inputs, 80 touch intensities excluding the top 10 touch intensity values and the bottom 10 touch intensity values An average value of the values may be determined as a target threshold value. According to another embodiment, the electronic device 101 may determine the median value as the target threshold value in order to increase the suitability of the target threshold value.

In an embodiment, the target threshold may be a value corresponding to an expected touch area value. The expected touch area value may be a touch area value that is a criterion for adjusting a touch intensity threshold value. The expected touch area value may be manually or automatically set in various ways as needed. For example, in the example of FIG. 3 , the expected touch area value may be approximately 40. For example, the expected touch area value may be automatically determined based on touch intensity values of a plurality of touch inputs.

When the touch area value of the touch input does not correspond to the expected touch area value, the electronic device 101 may adjust the touch intensity value of the corresponding touch input to a touch area value corresponding to the expected touch area value.

In operation 420, the electronic device 101 may determine whether to adjust the threshold value set for the touch screen 205 based on the target threshold value determined in operation 415.

For example, the electronic device 101 may determine a standard deviation of touch intensity values of a plurality of touch inputs used to determine the target threshold value. The electronic device 101 may determine not to adjust the threshold value when the threshold value set for the touch screen 205 is within a standard deviation range set for touch intensity values of a plurality of touch inputs. The electronic device 101 may determine to adjust the threshold value when the threshold value set for the touch screen 205 is not within the standard deviation range set for the touch intensity values of the plurality of touch inputs. For example, the standard deviation range may mean a standard deviation range such as 2 sigma or 3 sigma for touch intensity values used to determine the target threshold value. The standard deviation range may be set in various ways as needed.

As another example, the electronic device 101 determines whether a threshold value set on the touch screen 205 is within a specific percentage (eg, +/-5%, +/-10%, etc.) of touch intensity values of a plurality of touch inputs. Based on this, it is possible to determine whether or not to adjust the threshold value set on the touch screen 205 .

If it is determined in operation 420 to adjust the threshold value set for the touch screen 205, the electronic device 101 sets the threshold value set for the touch screen 205 as the target threshold value in operation 425. can be changed By changing the threshold value set for the touch screen 205 to a target threshold value, the electronic device 101 can provide a touch sensitivity suitable for the user.
