Electronic device and program

1. An electronic device equipped with an interface unit having a region on a screen that is visible to a user and that can accept touch operations by the user in the region, the region being a subset of the screen for adjusting a setting for a predetermined system, the electronic device comprising:

a storage unit that stores adjustment information in which an amount of change in a predetermined direction of a touch operation on the screen by the user, has been each associated with an amount of adjustment for adjusting the setting for the predetermined system; and

a control unit that

determines whether or not a passing through of the touch operation on the screen through the region in a predetermined amount of time has occurred,

wherein the passing through is the touch operation starting outside of the region, crossing into the region at least one time and ending outside the region,

calculates the amount of change in the predetermined direction of the touch operation by the user when it has been determined that passing through of the touch operation by the user through the region within the predetermined amount of time has occurred,

determines an amount of adjustment corresponding to the calculated amount of change based on the adjustment information, and

issues an instruction to the predetermined system to adjust the setting relative to a current setting based on the determined amount of adjustment.

2. The electronic device according to claim 1 , wherein the control unit instructs the predetermined system to set the setting corresponding to a position of the touch operation when it has been determined that the touch operation is inside the region.

3. The electronic device according to claim 1 , wherein the setting value of the predetermined system is a temperature setting value for an air conditioner installed in a vehicle in which the electronic device has been installed, an air flow setting value for the air conditioner, a volume setting value for audio equipment installed in the vehicle, or a volume setting value for the audio equipment.

4. The electronic device according to claim 1 , wherein the region is provided at a position away from an edge of the screen by a predetermined interval.

5. The electronic device according to claim 4 , wherein the control unit calculates the amount of change in the predetermined direction from a point at which the touch operation by the user was detected and a point at which the touch operation is no longer detected.

6. The electronic device according to claim 5 , wherein the control unit determines whether or not the touch operation has passed from an outer boundary line of the region to an inner boundary line of the region within the predetermined time.

7. A non-transitory computer-readable medium for causing a computer, in an electronic device equipped with an interface unit having a region on a screen that is visible to a user and that can accept touch operations by the user in the region, the region being a subset of the screen for adjusting a setting for a predetermined system, and a storage unit that stores adjustment information in which an amount of change in a predetermined direction of a touch operation by a user on the screen has been associated with an amount of adjustment for adjusting the setting for the predetermined system, to execute the steps of:

determining whether or not a passing through of the touch operation on the screen through the region in a predetermined amount of time has occurred;

wherein the passing through is the touch operation starting outside of the region, crossing into the region at least one time and ending outside the region, calculating the amount of change in the predetermined direction of the touch operation when it has been determined that passing through of the touch operation through the region within the predetermined amount of time has occurred;

issuing an instruction to the predetermined system to determine an amount of adjustment corresponding to the calculated amount of change based on the adjustment information; and

adjusting a setting relative to a current setting based on the determined amount of adjustment.

8. A method for using an electronic device equipped with an interface unit having a region on a screen that is visible to a user and that can accept touch operations by the user in the region, the region being a subset of the screen for adjusting a setting for a predetermined system, and a storage unit that stores adjustment information in which an amount of change in a predetermined direction of a touch operation by a user on the screen has been associated with an amount of adjustment for adjusting the setting for the predetermined system, the method including:

determining whether or not a passing through of the touch operation on the screen through the region in a predetermined amount of time has occurred;

wherein the passing through is the touch operation starting outside of the region, crossing into the region at least one time and ending outside the region,

calculating the amount of change in the predetermined direction of the touch operation when it has been determined that the touch operation has passed through the region within the predetermined amount of time has occurred;

issuing an instruction to the predetermined system to determine an amount of adjustment corresponding to the calculated amount of change based on the adjustment information; and

adjusting a setting relative to a current setting based on the determined amount of adjustment.
