Abstract

The information processing device includes: an operation detecting unit that determines that a first touch operation has been detected, calculates the length of a virtual line segment connecting the plurality of touched positions detected or the rotation angle with respect to a reference direction for the virtual line segment, and determines whether or not there has been a change in the length or rotation angle of a virtual line segment when coordinate information has been inputted, the touch panel displaying a second screen, and determines that a second touch operation has been detected when it has been determined that there has been a change in the length or rotation angle of the virtual line segment; and an execution instruction issuing unit that issues an instruction to execute the process associated with the change in the length of the virtual line segment or the rotation direction of the virtual line segment.

First claim

What is claimed is:

1. An information processing device connected to a touch panel comprising:
a processor;
a non-volatile storage device storing a control program; and
a temporary memory used by the processor for temporarily storing processing data,
wherein the processor, by executing the control program,
detects a first touch operation and a second touch operation on the touch panel based on coordinate information indicating a touched position inputted from the touch panel, wherein in the first touch operation, two fingers of a user contact on the touch panel, and in the second touch operation different from the first touch operation, the two fingers of the user touched on the touch panel move while keeping the two fingers on a touch panel,
displays a first screen in which control items including a first control item and a second control item and controllers including buttons, switches, or sliders to control the control items by one finger of the user are displayed on the touch panel after a power is turned on,
changes a display from the first screen to a second screen when the first touch operation has been detected, wherein the second screen displays a single circle graphic to control same functions of the first and second control items displayed on the first screen, and a first operation amount of the first control item and a second operation amount of the second control item are controlled by changing a size of a diameter of the circle graphic and rotating a pointer of the circle graphic in response to subsequent movement of the two fingers, and
issues an instruction to execute a process associated with the detected second touch operation when the second touch operation has been detected on the touch panel displaying the second screen,
wherein the processor determines that the first touch operation has been detected when two contact points on the touch panel displaying the first screen have been detected based on the coordinate information, and based on the coordinate information, calculates a length of a virtual line segment connecting the two contact points on the touch panel, and a rotation angle of the virtual line segment with respect to a reference direction, and
determines that the second touch operation has been detected when it has been determined that a change in the length or the rotation angle of the virtual line segment has occurred, and
wherein the size of the diameter of the circular graphic is changed with respect to the length of the virtual line segment and the processor issues an instruction to execute a process associated with the first operation amount indicating the diameter which control the same function of the first control item displayed on the first screen, and
a position of the pointer is changed with respect to the rotation angle and the processor issues an instruction to execute a process associated with the second operation amount indicating the position which control the same function of the second control item displayed on the first screen.

2. The information processing device according to claim 1 , wherein the processor displays a range graphic showing a possible moving range of the pointer indicating the second operation amount in the vicinity of the circumference of the circle graphic on the second screen.

3. A non-transitory computer-readable recording medium for a system including an information processing device and a touch panel, wherein the information processing device has a processor, a non-volatile storage device storing a control program, and a temporary memory used by the processor for temporarily storing processing data, the system including the information processing device comprising:
detecting a first touch operation and a second touch operation on the touch panel based on coordinate information indicating a touched position inputted from the touch panel, wherein in the first touch operation, contacting two fingers of a user on the touch panel, and in the second touch operation different from the first touch operation, moving the two fingers of the user touched on the touch panel while keeping the two fingers on a touch panel,
displaying a first screen in which control items including a first control item and a second control item and controllers including buttons, switches, or sliders to control the control items by one finger of the user are displayed on the touch panel after a power is turned on,
changing a display on the touch panel from the first screen to a second screen when the first touch operation has been detected in the detection step, wherein the second screen displays a single circle graphic to control same functions of the first and second control items displayed on the first screen, and a first operation amount of the first control item and a second operation amount of the second control item are controlled by changing a size of a diameter of the circle graphic and rotating a pointer of the circle graphic in response to subsequent movement of the two fingers,
issuing an instruction to execute a process associated with the detected second touch operation when the second touch operation has been detected in the detection step on the touch panel displaying the second screen,
determining that the first touch operation has been detected when two contact points on the touch panel displaying the first screen have been detected based on the coordinate information, and based on the coordinate information, calculating a length of a virtual line segment connecting two contact points on the touch panel, and a rotation angle of the virtual line segment with respect to a reference direction,
determining that the second touch operation has been detected when it has been determined that a change in the length or the rotation angle of the virtual line segment has occurred, and
changing the size of the diameter of the circular graphic with respect to the length of the virtual line segment and issuing an instruction to execute a process associated with the first operation amount indicating the diameter which control the same function of the first control item displayed on the first screen, and
changing a position of the pointer with respect to the rotation angle and issuing an instruction to execute a process associated with the second operation amount indicating the position which control the same function of the second control item displayed on the first screen.
