Abstract

An input device (2a) includes: a position/angle determining section (505) for determining an adjacent region (F1) and defining, in the adjacent region (F1), an input coordinate system that is in common with a counterpart device; a detection position control section (701) for determining first detection coordinates indicating a user operation performed in the adjacent region (F1) in the input coordinate system; and a data transmitting and receiving section (506) for transmitting the first detection coordinates to the counterpart device.

Claims

1. An input device capable of, while a first panel component of the input device is placed next to a second panel component of a counterpart device, accepting an input of a continuous track made through contact of the target object or approach thereof, the continuous track extending from the first panel component to the second panel component, the input device comprising:

a region determining section for, at an occurrence of contact of the counterpart device with the input device or approach thereof to the input device, determining a first adjacent region and defining, in the first adjacent region, an input coordinate system that is in common with the counterpart device, the first adjacent region being a region located in the first panel component so as to be adjacent to the second panel component;

a detection position determining section for, upon detection of a user operation performed in the first adjacent region, determining first detection coordinates indicating a position of the user operation in the input coordinate system; and

a transmitting section for transmitting, to the counterpart device, the first detection coordinates determined by the detection position determining section.

2. The input device according to claim 1, wherein

the transmitting section transmits, to the counterpart device, the first detection coordinates and image information representing an image having been displayed on a display screen of the input device in accordance with the user operation.

5. The input device according to claim 1, wherein

the first panel component and the second panel component are touch panels that are capacitive touch panels which detect contact of the target object or approach thereof,

the touch panels each include sense lines each capable of receiving a pulse signal applied to at least one of counterpart-side drive lines which are provided in the capacitive touch panel of the counterpart device having contacted or approached the input device, and

the region determining section determines a positional relation between the input device and the counterpart device by judging which of the sense lines provided in the touch panel has received the pulse signal having been transmitted from the counterpart-side drive line.

3. An input device capable of, while a second panel component of the input device is placed next to a first panel component of a counterpart device, accepting an input of a continuous track made through contact of the target object or approach thereof, the continuous track extending from the first panel component to the second panel component, the input device comprising:

a region determining section for, at an occurrence of contact of the counterpart device with the input device or approach thereof to the input device, determining a second adjacent region and defining, in the second adjacent region, an input coordinate system that is in common with the counterpart device, the second adjacent region being a region located in the second panel component so as to be adjacent to the first panel component;

a receiving section for receiving first detection coordinates, determined by the counterpart device, indicating, in the input coordinate system, a position of a user operation performed in a first adjacent region, the first adjacent region being a region located in the first panel component so as to be adjacent to the second panel component;

a detection position determining section for, upon detection of a user operation performed in the second adjacent region, determining second detection coordinates indicating a position of the user operation in the input coordinate system;

a position judging section for judging whether the second detection coordinates having been determined by the detection position determining section match the first detection coordinates having been received by the receiving section or whether the second detection coordinates is present in a predetermined range where the second detection coordinates are deemed to match the first detection coordinates; and

an input judging section for, in a case where the position judging section has judged that the second detection coordinates match the first detection coordinates or that the second detection coordinates are present in the predetermined range, judging the second detection coordinates as being the input of the continuous track.

4. The input device according to claim 3, wherein

the receiving section receives the first detection coordinates and image information representing an image having been displayed on a display screen of the counterpart device, and

the input device further comprises a display control section for causing a display screen of the input device to display, in accordance with the user operation, an image represented by the image information having been received by the receiving section.

6. A display device capable of displaying an image related to an image displayed on a counterpart device, the display device comprising:

a determining section for determining a position of the counterpart device in relation to the display device at an occurrence of contact of the counterpart device with the display device or approach thereof to the display device;

an image control section for generating, according to the position of the counterpart device which position has been determined by the determining section, a first image to be displayed on a display screen of the display device and generating image generation information required for the counterpart device to generate, according to the position of the counterpart device, a second image, related to the first image, to be displayed on a display screen of the counterpart device; and

transmitting section for transmitting, to the counterpart device, the image generation information having been generated by the image control section.

7. The display device according to claim 6, wherein

the determining section judges whether a previously-determined position of the counterpart device matches a currently-determined position of the counterpart device, and

in a case where the determining section has judged that there is no match between the previously-determined position and the currently-determined position, the image control section generates the first image and the image generation information.

8. The display device according to claim 6, wherein

the image control section generates the second image instead of the image generation information, and

the transmitting section transmits, to the counterpart device, the second image having been generated by the image control section.

9. A display device capable of displaying an image related to an image displayed on another display device, recited in claim 6 or 7, as a counterpart device,

the display device comprising:

a receiving section for receiving the image generation information; and

an image control section for generating the second image on a basis of the image generation information.

10. The display device according to claim 6, further comprising:

a touch panel being a capacitive touch panel which detects contact of a target object or approach thereof,

the touch panel including sense lines each capable of receiving a pulse signal applied to at least one of counterpart-side drive lines which are provided in a capacitive touch panel of a counterpart device having contacted or approached the display device, and

the determining section determining a positional relation between the display device and the counterpart device by judging which of the sense lines provided in the touch panel has received the pulse signal having been transmitted from the counterpart-side drive line.
