Abstract

A connection device connected to an image display unit that is head-mounted includes a connector to which an image signal is input; and a connector to which an image signal is input and which is capable of outputting sensor data. The connection device further includes a setting unit that sets a selection between the image signals; and an output control unit that selects the connector for outputting the image signal by a connection unit according to the setting. The setting unit sets the image signal to be output from the connection unit when the image signal is input.

First claim

What is claimed is:

1. A connection device transmitting an image signal to a display device that is head-mounted, the connection device comprising:
a first connection unit that receives a first image signal;
a second connection unit that receives a second image signal and transmits data relating to an input device of the display device, the second image signal being different from the first image signal;
an output control unit that selects one of the first image signal and the second image signal; and
an output unit that outputs one of the first image signal and the second image signal that is selected by the output control unit to the display device, wherein
when both the first connection unit has received the first image signal and the second connection unit has received the second image signal, the output control unit causes the output unit to output the first image signal to the display device.

2. The connection device according to claim 1 , further comprising:
a setting unit that acquires a history of outputting of the first image signal to the display device by the output unit and a history of outputting of the second image signal to the display device by the output unit, wherein
the output control unit selects one of the first image signal and the second image signal based on the history of outputting that is acquired by the setting unit.

3. The connection device according to claim 2 , wherein
the setting unit counts an output time of outputting the first image signal to the display device by the output unit and an output time of outputting the second image signal to the display device by the output unit, and
the output control unit selects one of the first image signal and the second image signal based on the output time of outputting that is counted by the setting unit.

4. The connection device according to claim 3 , further comprising:
a connection detector that detects a first external device and a second external device that is different from the first external device, wherein
the first external device transmits the first image signal to the first connection unit,
the second external device transmits the second image signal to the second connection unit, and
the setting unit counts the output time of outputting the first image signal to the display device by the output unit in association with the first external device, and counts the output time of outputting the second image signal to the display device by the output unit in association with the second external device.

5. The connection device according to claim 1 , wherein
the first connection unit and the second connection unit receive the first image signal and the second image signal by a wireless communication, respectively.

6. The connection device according to claim 1 , further comprising:
a connection detector that detects each of the first image signal to be received by the first connection unit and the second image signal to be received by the second connection unit.

7. A display device that is head-mounted comprising:
an image display unit that displays an image; and
a connection device that includes a first connection unit and a second connection unit, the first connection unit receives a first image signal, the second connection unit receives a second image signal and transmits data relating to an input device of the display device, the second image signal being different from the first image signal, wherein
the connection device is configured to:
select one of the first image signal and the second image signal;
output one of the first image signal and the second image signal that is selected by the connection device to the image display unit; and
when both the first connection unit has received the first image signal and the second connection unit has received the second image signal, output the first image signal to the image display unit.

8. The display device according to claim 7 , further comprising:
a connection detector that detects each of the first image signal to be received by the first connection unit and the second image signal to be received by the second connection unit.

9. The display device according to claim 7 , wherein
the connection device is configured to detect each of the first image signal to be received by the first connection unit and the second image signal to be received by the second connection unit.

10. A control method for a head-mounted display device, the head-mounted display device including an image display unit that displays an image and a connection device including a first connection unit and a second connection unit, the first connection unit receiving a first image signal, the second connection unit receiving a second image signal and transmitting data relating to an input device of the display device, the second image signal being different from the first image signal, the control method comprising:
selecting one of the first image signal and the second image signal; and
outputting one of the first image signal and the second image signal that is selected to the image display unit, wherein
when both the first connection unit has received the first image signal and the second connection unit has received the second image signal, outputting the first image signal to the image display unit.
