Head-mount display and head-mount display system
A head-mount display comprises a display and a controller. The controller is configured to: acquire a first sensor output outputted from an ambient monitoring sensor configured to monitor an ambient environment of the head-mount display to determine presence or absence of an abnormality in the ambient environment; acquire a second sensor output outputted from a condition monitoring sensor configured to monitor biometric information of a user wearing the head-mount display to determine presence or absence of a factor of decreasing attention due to a user's condition; determine the display mode at a time of displaying the virtual space information on the display based on both the presence or absence of the abnormality in the ambient environment and the factor of decreasing attention due to the user's condition; and display the virtual space information on the display in the determined display mode.
1 . A head-mount display comprising:
a display;
a camera configured to capture a real space in front of the head-mount display;
a line-of-sight sensor configured to detect a movement of a user's eye of the head-mount display; and
a processing circuit,
wherein the processing circuit is configured to:
generate a virtual object;
display the generated virtual object and a real object included in the real space captured by the camera on the display;
acquire a detection result of the line-of-sight sensor to determine whether the line-of-sight remains on the real object displayed on the display for a predetermined time or longer and the user is gazing at the real object, and whether the movement of the user's eye within a predetermined time period is below a threshold;
control the display to display the virtual object in a normal display mode when determining the user is not gazing at the real object and the movement of the user's eye is equal to or above the threshold;
control the display to display the virtual object in a specific display mode different from the normal display mode so that display of the virtual object does not interrupt or disturb viewing of the real object, when determining the user is gazing at the real object and the movement of the user's eye is equal to or above the threshold; and
control the display to stop displaying the virtual object when determining the movement of the user's eye is below the threshold regardless of whether the user is gazing at the real object.

10 . The head-mount display according to claim 1 ,
wherein, when a redisplay input instruction is inputted by the user after stopping the display of the virtual object, the processing circuit is configured to control the display so as to resume display of the virtual object.
11 . A head-mount display comprising:
a display;
a camera configured to capture a real space in front of the head-mount display;
a line-of-sight sensor configured to detect a movement of a user's eye of the head-mount display; and
a processing circuit,
wherein the processing circuit is configured to:
generate a virtual object;
display the generated virtual object and a real object included in the real space captured by the camera on the display;
acquire a detection result of the line-of-sight sensor to determine whether the line-of-sight remains on the real object displayed on the display for a predetermined time or longer and the user is gazing at the real object, and whether a predetermined movement of the user's eye is performed;
control the display to display the virtual object in a normal display mode when determining the user is not gazing at the real object and the predetermined movement of the user's eye is not performed;
control the display to display the virtual object in a specific display mode different from the normal display mode so that display of the virtual object does not interrupt or disturb viewing of the real object, when determining the user is gazing at the real object and the predetermined movement of the user's eye is not performed; and
control the display to stop displaying the virtual object when determining the predetermined movement of the user's eye is performed regardless of whether the user is gazing at the real object.
