Abstract

There is provided a mobile display apparatus applied to the display apparatus including a display screen; a touch panel that detects an operation performed by a user in the display screen; state decision unit that decides one of a contact state, a proximity state and a distant state with the display screen based on the user'"'"'s operation detected by the touch panel; a state change identification unit that identifies a state change in the user'"'"'s operation according to the state decided by the state decision unit; and an operation command setting unit that sets an operation command depending on the state change identified by the state change identification unit when setting the operation command for controlling display of the display screen in response to the user'"'"'s operation.

Claims

1. A display apparatus comprising:

a display screen;

a device that detects an operation performed by a user in the display screen;

a state decision unit that decides one of a contact state, a proximity state and a distant state with the display screen based on the user'"'"'s operation detected by the device;

a state change identification unit that identifies a state change in the user'"'"'s operation according to the state decided by the state decision unit; and

an operation command setting unit that sets an operation command depending on the state change identified by the state change identification unit when setting the operation command for controlling display of the display screen in response to the user'"'"'s operation.

2. The display apparatus according to claim 1, further comprising:

a screen control unit that changes display of the display screen according to the operation command set by the operation command setting unit.

3. The display apparatus according to claim 1, wherein

the state change identification unit identifies from which to which of the contact state, the proximity state and the distant state the operation performed by a user in the display screen has changed based on a decision result by the state decision unit, and

the operation command setting unit sets a different operation command depending on the state change identified by the state change identification unit.

4. The display apparatus according to claim 3, further comprising:

a storage unit that stores a previous decision result by the state decision unit, wherein

the state change identification unit identifies a state change from the contact state to the distant state with the display screen or a state change from the contact state to the proximity state with the display screen based on the previous decision result stored in the storage unit and a current decision result by the state decision unit, and

the operation command setting unit sets a different operation command depending on the state change identified by the state change identification unit.

5. The display apparatus according to claim 2, wherein

when the state change identified by the state change identification unit is a state change from the contact state to the distant state, the operation command setting unit directs the screen control unit to execute the set operation command.

6. The display apparatus according to claim 2, wherein

when the state change identified by the state change identification unit is a state change from the contact state to the proximity state, the operation command setting unit directs the screen control unit to refrain from executing the set operation command.

7. A display method comprising the steps of:

detecting an operation performed by a user in a display screen by a device;

deciding one of a contact state, a proximity state and a distant state with the display screen based on the user'"'"'s operation detected by the device;

identifying a state change in the user'"'"'s operation according to the decided state; and

setting an operation command depending on the identified state change when setting the operation command for controlling display of the display screen in response to the user'"'"'s operation.

8. A program causing a computer to execute a process comprising processing of:

detecting an operation performed by a user in a display screen by a device;

deciding one of a contact state, a proximity state and a distant state with the display screen based on the user'"'"'s operation detected by the device;

identifying a state change in the user'"'"'s operation according to the decided state; and

setting an operation command depending on the identified state change when setting the operation command for controlling display of the display screen in response to the user'"'"'s operation.
