[0049] see Figure 6 , is a flow chart of the sensor power adjustment method in the second embodiment of the present invention. The method is applied to the aforementioned head-mounted display device 100 . Compared with the first embodiment, the method in the second embodiment has more steps, and the execution order is not limited to Figure 6 In the order shown, the method comprises the steps of:

[0050] Determine the application currently running on the head-mounted display device 100 (S601).

[0051] The transmitting frequency of the transmitter 21 is adjusted according to the application currently running on the head-mounted display device 100 (S603).

[0052] Judging the wear / take off state of the head-mounted display device 100 according to the receiving result of the reflected sensor signal received by the receiver 22 ( S605 ). In some embodiments, the step S605 includes: comparing the strength of the sensing signal received by the receiver 22 with a wear / take off ...

Abstract

The present invention provides a head-mountable display device (100), comprising a processor (10) and a sensor (20); the sensor (20) comprises a transmitter (21) and a receiver (22); the transmitter (21) is used for sending a sensing signal at a preset transmission frequency, and the receiver (22) is used for receiving the sensing signal reflected back; the processor (10) is used for adjusting thetransmission frequency of the transmitter (21) according to an application currently being run by the head-mountable display device (100). In the head-mountable display device (100) and sensor (20) power conditioning method, it is possible to adjust the transmission frequency of the transmitter (21) according to a requirement, of a currently running application, of response speed with regard to achange in the wearing / removal state of the head-mountable display device (100), such that the transmission frequency of the transmitter (21) is reduced so that it satisfies the requirement, reducingenergy consumption.

Description

technical field [0001] The present invention relates to a display device, in particular to a head-mounted display device and a power adjustment method for a sensor of the head-mounted display device. Background technique [0002] Head-mounted display devices have been gradually favored by people due to their convenience and the ability to achieve stereoscopic display and stereophonic effects. In recent years, with the emergence of a virtual reality (virtual reality, VR) technology, a head-mounted display device, as a hardware support device of the VR technology, is more widely used. At present, the head-mounted display device often needs to detect whether the user puts on or takes off the head-mounted display device to perform some corresponding operations. A common detection method is to detect whether there is a human head in the head-mounted display device through sensors such as sensors to determine whether the user puts on or takes off the head-mounted display device. ...
