Abstract

A control surface has a first area configured to accept a first operation performed with an object for enabling a first function of the controlled device, a second area configured to accept a second operation performed with the object for enabling a second function of the controlled device, and a third area located between the first and second areas. A processing device is configured to: enable the third area to accept the first operation in a case where it is determined that an object contacts or approaches the first area; enable the third area to accept the second operation in a case where it is determined that the object contacts or approaches the second area; and disable acceptance of the first operation and the second operation in a case where it is determined that the objects contacts or approaches the third area prior to the first and second areas.

First claim

What is claimed is:

1. A remote control device adapted to be installed in a mobile entity to control an operation of a controlled device, comprising:
a control surface having a first area configured to accept a first operation performed with an object for enabling a first function of the controlled device, a second area configured to accept a second operation performed with the object for enabling a second function of the controlled device, and a third area located between the first area and the second area;
a detector configured to detect an electrostatic capacity between the control surface and the object; and
a processing device configured to:
determine that the object contacts or approaches the first area, the second area or the third area, based on the electrostatic capacity;
enable the third area to accept the first operation in a case where it is determined that the object contacts or approaches the first area;
enable the third area to accept the second operation in a case where it is determined that the object contacts or approaches the second area; and
disable acceptance of the first operation and the second operation in a case where it is determined that the objects contacts or approaches the third area prior to the first area and the second area.

2. The remote control device according to claim 1 ,
wherein the second operation is an operation in which a position of the object that is to be detected relative to the control surface changes with a speed that is less than a threshold value; and
wherein the processing device is configured to enable the first area to accept the second operation when the second area begins to accept the second operation.

3. The remote control device according to claim 1 ,
wherein the controlled device is equipped with a display section configured to display an image;
wherein the second operation is an operation for associating a position in the control surface with a position in the image; and
wherein the processing device is configured to enable the first area to accept the second operation when the second area begins to accept the second operation.

4. The remote control device according to claim 1 ,
wherein the processing device is configured to maintain an initial state of each of the first area and the second area in a case where it is determined that the object contacts or approaches plural positions on the control surface.

5. A processing device adapted to be installed in a remote control device configured to remotely control an operation of a controlled device in a mobile entity, comprising:
a reception interface configured to receive a detection signal corresponding to an electrostatic capacity between an object and a control surface having a first area configured to accept a first operation performed with the object for enabling a first function of the controlled device, a second area configured to accept a second operation performed with the object for enabling a second function of the controlled device, and a third area located between the first area and the second area; and
a processor configured to:
determine that the object contacts or approaches the first area, the second area or the third area, based on the electrostatic capacity;
enable the third area to accept the first operation in a case where it is determined that the object contacts or approaches the first area;
enable the third area to accept the second operation in a case where it is determined that the object contacts or approaches the second area; and
disable acceptance of the first operation and the second operation in a case where it is determined that the objects contacts or approaches the third area prior to the first area and the second area.

6. A non-transitory computer-readable medium having recorded a computer program adapted to be executed by a processor in a processing device adapted to be installed in a remote control device configured to remotely control an operation of a controlled device in a mobile entity, the computer program being configured to, when executed, cause the processing device to:
receive a detection signal corresponding to an electrostatic capacity between an object and a control surface having a first area configured to accept a first operation performed with the object for enabling a first function of the controlled device, a second area configured to accept a second operation performed with the object for enabling a second function of the controlled device, and a third area located between the first area and the second area;
determine that the object contacts or approaches the first area, the second area or the third area, based on the electrostatic capacity;
enable the third area to accept the first operation in a case where it is determined that the object contacts or approaches the first area;
enable the third area to accept the second operation in a case where it is determined that the object contacts or approaches the second area; and
disable acceptance of the first operation and the second operation in a case where it is determined that the objects contacts or approaches the third area prior to the first area and the second area.
