Abstract

It is intended to be able to perform an input operation with a simple configuration in which the number of components such as keys or switches is reduced. A remote controller (1) includes an angular velocity detecting section (21) for detecting an angular velocity caused in a casing when a user indicates a specific position of the casing held by the user, an operation determining section (3) for determining the indicated specific position on the basis of the angular velocity detected by the angular velocity detecting section (21), and a control command transmitting section (91) for transmitting a control command to an external device on the basis of the determination result of the operation determining section (30).

Claims

1. A portable input device that is held by a user, comprising:

a displacement detecting section that detects an operation of moving a finger of the user holding a casing to indicate a specific position on the casing as a displacement of the casing; and

an operation determining section that determines an input operation to the specific position on the basis of the displacement detected by the displacement detecting section and outputs a determination result.

2. The portable input device according to claim 1, further comprising:

a reference position detecting section that detects that a predetermined reference position on the casing is indicated,

wherein the operation determining section determines the specific position on the basis of a detection result by the reference position detecting section and the displacement detected by the displacement detecting section after the reference position is indicated.

3. The portable input device according to claim 2, wherein the operation determining section determines that the determination result before the reference position is indicated is invalid when the reference position detecting section detects that the reference position is indicated.

4. The portable input device according to claim 1, wherein the operation determining section determines the specific position on the basis of the displacement detected by displacement detecting section and a table in which displacement and specific positions are correlated with each other.

6. The portable input device according to claim 1, wherein the operation determining section determines the specific position on the basis of the displacement of the casing which assists a movement of the finger for indicating the specific position.

5. An input method in a portable input device that is held by a user, comprising:

a first step of detecting an operation of moving a finger of the user holding a casing to indicate a specific position on the casing as a displacement of the casing

a second step of determining an input operation to the specific position on the basis of the displacement detected in the first step; and

a third step of outputting a determination result of the second step.
