Abstract
A head-mounted display device that enables a user to simultaneously visually recognize a virtual image and an outside scene includes a photographing unit configured to photograph at least a part of a visual field direction of the user in a state in which the user wears the head-mounted display device and acquire a motion of the user; a track acquiring unit configured to acquire a track of the motion of the user from the motion photographed by the photographing unit; and an authentication processing unit configured to authenticate, using the track acquired by the track acquiring unit, whether the user is a proper user.
Claims14
A head-mounted display device that enables a user to simultaneously visually recognize a virtual image and an outside scene, the head-mounted display device comprising:
- a photographing unit configured to photograph at least apart of a visual field direction of the user in a state in which the user wears the head-mounted display device and acquire a motion of the user, the photographing unit starts photographing the motion when it detects a preset start trigger, and stops photographing the motion when it detects a preset end trigger;
- a track acquiring unit configured to acquire a track of the motion of the user from the motion photographed by the photographing unit;
- an authentication processing unit configured to authenticate, using the track acquired by the track acquiring unit, whether the user is a proper user;
- and
- a guidance unit configured to inform the user of an overlapping region where a display region of the virtual image and a photographing region of the photographing unit overlap, the photographing region being a region, smaller than a total photographing region of the photographing unit, where performance of the photographing unit is assured,
- wherein the start trigger and end trigger are different from the track acquired by the track acquiring unit.
A control method for a head-mounted display device that enables a user to simultaneously visually recognize a virtual image and an outside scene, the control method comprising:
- (a) informing the user of an overlapping region where a display region of the virtual image and a photographing region overlap, the photographing region being a region, smaller than a total photographing region, where photographing performance is assured;
- (b) detecting a preset start trigger;
- (c) photographing at least a part of a visual field direction of the user in a state in which the user wears the head-mounted display device and acquiring a motion of the user subsequent to (b);
- (d) acquiring a track of the motion of the user from the motion photographed in (c), the track being different from the preset start trigger detected in (b);
- (e) detecting a preset end trigger that is different from the track acquired in (d);
- (f) stopping the photographing in (c) subsequent to (e);
- and
- (g) authenticating, using the track acquired in (d), whether the user is a proper user.
An authentication system comprising:
- a head-mounted display device that enables a user to simultaneously visually recognize a virtual image and an outside scene;
- and
- an authentication server that performs authentication of the user, wherein
- the head-mounted display device includes:
- a photographing unit configured to photograph at least a part of a visual field direction of the user in a state in which the user wears the head-mounted display device and acquire a motion of the user, the photographing unit starts photographing the motion when it detects a preset start trigger, and stops photographing the motion when it detects a preset end trigger;
- a guidance unit configured to inform the user of an overlapping region where a display region of the virtual image and a photographing region of the photographing unit overlap, the photographing region being a region, smaller than a total photographing region of the photographing unit, where performance of the photographing unit is assured;
- and
- a transmitting unit configured to transmit the motion acquired by the photographing unit to the authentication server, and
- the authentication server includes:
- a track acquiring unit configured to acquire a track of the motion of the user from the motion received from the head-mounted display device;
- an authentication processing unit configured to authenticate, using the track acquired by the track acquiring unit, whether the user is a proper user;
- and
- a transmitting unit configured to transmit a result of the authentication by the authentication processing unit to the head-mounted display device,
- the start trigger and end trigger being different from the track acquired by the track acquiring unit.
