In some embodiments, the electronic device 1 may not preset the first preset density value, that is, the first preset density value is a change value, which may be calculated by the calculation module 103. Adapt the density by tapping the density.

For example, the calculation module 103 sorts the calculated tap density from large to small, and selects a tap density value of a preset number of bits (for example, the fourth last digit) as the first preset density value. In other embodiments, the calculation module 103 can also sort the calculated tap densities from small to large. The order of sorting is not limited herein, and the selection of the first preset density value is not limited to the above-exemplified embodiment.

In some embodiments, the determining module 102 compares the tap density with the first preset density value, and determines an area corresponding to the tap density less than the first preset density value as a safe operation. The area, that is, the area where the user can perform the tapping operation next time; the area corresponding to the tapping density greater than the first preset density value is determined as the non-secure operation area, that is, the area where the user cannot perform the tapping operation next time. .

The determining module 102 determines an area in which the tapping density is smaller than the coordinate range corresponding to the first preset density value, and the determining module 102 sets the tapping density to be greater than or equal to the first pre-predetermined The area in which the coordinate ranges corresponding to the density values are combined is determined as the non-safe operation area.

The prompt may be a voice prompt or a text display.

The following is an illustration of three application examples illustrating the knocking system 10 of the present invention against screen damage.

Application scenario 1

When the user touches the display screen 16 at the first moment, the recording module 101 records the location information of the first tap point when the tap signal is detected, and the determining module 102 determines the area where the first tap point is located. The computing module 103 calculates a tap density for the region, and the update module 104 updates the tapped density that has been stored in the memory. The calculating module 103 sorts the tapping density calculated at the first moment from large to small, and selects the tapping density value ranked fourth in the last digit as the first preset density value, and the determining module 102 The area in which the tapping density is smaller than the coordinate range corresponding to the first preset density value is determined as the safe operating area. The display module 105 highlights all of the safe operating areas.

At the second moment, the user taps the display screen 16, and the recording module 101 records the position information of the second tap point when the tap signal is detected again. The tapping instruction corresponding to the tapping of the display screen 16 in the electronic device 1 is an instruction to trigger playing of music, and thus, the triggering module 107 plays music.

Application scenario 2

When the user touches the display screen 16 at the first moment, the recording module 101 records the location information of the first tap point when the tap signal is detected, and the determining module 102 determines the area where the first tap point is located. The computing module 103 calculates a tap density for the region, and the update module 104 updates the tapped density that has been stored in the memory. The determining module 102 determines an area in which the tapping density is smaller than a coordinate range corresponding to the first preset density value (pre-set to 3 times) as a safe operating area. The display module 105 randomly selects one coordinate range in the safe operation area, and flashes the above-mentioned coordinate range to prompt the user for the position that should be tapped at the second time.

At the second moment, the user taps the position displayed on the display screen 16 by blinking, and the recording module 101 records the position information of the second tap point when the tap signal is detected again. There is no tap command corresponding to the display screen 16 being tapped twice in the electronic device 1, and thus the trigger module 107 does not trigger any function.

In application scenario 3, the number of taps corresponding to the tap command that triggers the screen capture function on the electronic device 1 is three.

When the user touches the display screen 16 at the first moment, the recording module 101 records the location information of the first tap point when the tap signal is detected, and the determining module 102 determines the area where the first tap point is located. The computing module 103 calculates a tap density for the region, and the update module 104 updates the tapped density that has been stored in the memory. The calculating module 103 sorts the tapping density calculated at the first moment from large to small, and selects the tapping density value ranked fourth in the last digit as the first preset density value, and the determining module 102 The area in which the tapping density is smaller than the coordinate range corresponding to the first preset density value is determined as the safe operating area. The display module 105 visibly displays an image on the area in the safe operation area that is closest to the position of the first tap operation.

At the second moment, the user taps the display screen 16, and the recording module 101 records the location information of the second tap point when the tap signal is detected for the second time. The calculation module 103 calculates a tap density on the display screen 16. The calculation module 103 selects the tap density value ranked in the fourth last digit as the first preset density value, and the determining module 102 combines the tapping density to be smaller than the coordinate range corresponding to the first preset density value. The area is determined as a safe operating area. The display module 105 fades the image on the area of the preset area corresponding to the minimum tap density of the safe operation area.

At the third moment, the user taps the display screen 16, and the recording module 101 records the location information of the third tap point when the tap signal is detected for the third time. The tapping command corresponding to the three times of the display screen 16 in the electronic device 1 is an instruction for triggering the screen capture. Therefore, the triggering module 107 performs a screen capture on the current interface, and then resumes the normal use interface.
