Touch input judgment device, touch panel input device, touch input judgment method, and a computer readable medium

A computer readable medium storing a touch input judgment program for causing a computer to execute a touch input judgment method of changing and determining a selection value based on a touch operation on a touch panel, wherein the touch input judgment program causes the computer to execute:

• a process of determining a selection value change amount, to be added to a current selection value, when a rotation operation in a normal direction is inputted through the touch panel and storing rotation direction information indicating the normal direction in a storage unit when a rotation operation in the normal direction as a first rotation operation is performed;
• a process of judging that a rotation operation subsequent to the first rotation operation is a return operation of a finger position when the subsequent rotation operation is a finger movement in a direction reverse to the direction indicated by the rotation direction information;
• a process of setting a new current selection value after a change to a value obtained by adding the selection value change amount to the current selection value when the subsequent rotation operation is a rotation operation in the normal direction and maintaining the current selection value without change when the subsequent rotation operation is judged to be the return operation of the finger position;
• and
• a process of determining the current selection value according to the touch operation on the touch panel.

A touch input judgment device that changes a selection value based on a touch operation on a touch panel, the touch input judgment device comprising:

• a processor to execute a program;
• and
• a memory to store the program which, when executed by the processor, performs
• a process of determining a selection value change amount, to be added to a current selection value, when a rotation operation in a normal direction is inputted through the touch panel and storing rotation direction information indicating the normal direction in the memory when a rotation operation in the normal direction as a first rotation operation is performed;
• a process of judging that a rotation operation subsequent to the first rotation operation is a return operation of a finger position when the subsequent rotation operation is a finger movement in a direction reverse to the direction indicated by the rotation direction information;
• a process of setting a new current selection value after a change to a value obtained by adding the selection value change amount to the current selection value when the subsequent rotation operation is a rotation operation in the normal direction and maintaining the current selection value without change when the subsequent rotation operation is judged to be the return operation of the finger position;
• and
• a process of determining the current selection value according to the touch operation on the touch panel.

A touch panel input device comprising:

• a touch panel that receives a touch operation;
• and
• a touch input judgment device that changes and determines a selection value based on the touch operation, the touch input judgment device including:
• a processor to execute a program;
• and
• a memory to store the program which, when executed by the processor, performs
• a process of determining a selection value change amount, to be added to a current selection value, when a rotation operation in a normal direction is inputted through the touch panel and storing rotation direction information indicating the normal direction in the memory when a rotation operation in the normal direction as a first rotation operation is performed;
• a process of judging that a rotation operation subsequent to the first rotation operation is a return operation of a finger position when the subsequent rotation operation is a finger movement in a direction reverse to the direction indicated by the rotation direction information;
• a process of setting a new current selection value after a change to a value obtained by adding the selection value change amount to the current selection value when the subsequent rotation operation is a rotation operation in the normal direction and maintaining the current selection value without change when the subsequent rotation operation is judged to be the return operation of the finger position;
• and
• a process of determining the current selection value according to the touch operation on the touch panel.
