Abstract
A sensor data providing unit included in a control device provides, when an HMD is connected, detection data acquired by a sensor driver as standard sensor data, and continues an operation of acquiring detection data of a first sensor by the sensor driver, and provides, when the HMD is not connected, detection data acquired by a built-in sensor driver as standard sensor data.
Claims9
A data processing device, comprising:
- a first sensor;
- a connection unit connected to a head mounted display, the head mounted display including a second sensor and a display unit;
- an application execution unit executing an application that uses at least one of detection data of the first sensor and detection data of the second sensor;
- and
- a sensor data providing unit providing each of detection data of a first standard sensor and detection data of an extended sensor to the application execution unit, wherein
- the sensor data providing unit includes a first data acquisition unit that acquires detection data of the first sensor, and a second data acquisition unit that acquires detection data of the second sensor,
- when the head mounted display is connected to the connection unit, the sensor data providing unit always provides the detection data acquired from the second sensor of the head mounted display by the second data acquisition unit as detection data of the first standard sensor and always provides the detection data acquired from the first sensor by the first data acquisition unit as detection data of the extended sensor, and
- when the head mounted display is not connected to the connection unit, the sensor data providing unit provides the detection data acquired from the first sensor by the first data acquisition unit both detection data of the first standard sensor and as detection data of the extended sensor.
