AI Technical Summary

Technical Problem

Existing head-mounted display (HMD) technologies face issues with unnecessary power consumption and display deterioration due to inappropriate turning off or restarting, such as when a user is using the HMD but it turns off, or when handing it to another user, the display does not immediately turn on.

Method used

A control device with detection means for movement, wearing, and state of the HMD, transitioning the display state based on duration of non-detection of movement or wearing to appropriate stop and restart states, using sensors like line-of-sight, proximity, acceleration, and gyro sensors to manage display effectively.

Benefits of technology

Enables suitable turning off and on of the HMD display, reducing unnecessary power consumption and display deterioration, allowing immediate usability when resumed, and optimizing power management based on user interaction and movement.

Abstract

To provide a technique that enables a head-mounted display device such as an HMD to be conveniently turned off (stop display) and turned on (restart display).SOLUTION: A control device includes first detection means for detecting the movement of a head-mounted display device, second detection means for detecting the wearing of the display device by a user, and control means for transitioning the state of the display device to a first display stop state when a duration time of a state where movement of the display device is not detected reaches a first time in a state where the wearing of the display device by the user is not detected in a case where the state of the display device is a display state, transitioning the state of the display state to the display state when the movement of the display device is detected in a case where the state of the display device is a first display stop state, and transitioning the state of the display device to a second display stop state when the duration time of the state where the wearing of the display device by the user is not detected reaches a second time in a case where the state of the display device is the display state.SELECTED DRAWING: Figure 2
