Head-mounted device, control method and control program for head-mounted device
A head-mounted device includes a mounted member that is mounted on a head of a user, a sensor unit, which is a detection device, that detects a posture of the mounted member, a control device that switches a control mode according to the posture detected in the sensor unit, and a video output device and an audio output device as output devices that perform output operations according to the control mode in the control device.
1. A head-mounted device comprising:
a mounted member mounted on a head of a user;
a detection device that detects a posture of the mounted member;
an output device that outputs at least one of an image or sound; and
a control device that switches a control mode of the output device and that receives an input signal related to the switching of the control mode, wherein
the control device determines whether the input signal is valid according to the posture of the mounted member detected by the detection device,
the output device includes a first display device and a second display device,
the detection device detects the posture of the mounted member with a rotation axis that is an axis along a direction in which the first display device and the second display device are aligned, and
the control device determines whether the input signal is valid according to a rotation angle formed by a virtual plane orthogonal to a vertical direction and the direction in which the first display device and the second display device are aligned, and a direction orthogonal to the direction in which the first display device and the second display device are aligned in the mounted member.
2. The head-mounted device according to claim 1 , wherein the control device treats an impact received by the mounted member as the input signal when the rotation angle is within a predetermined range.
3. The head-mounted device according to claim 2 , wherein the control device disables reception of the input signal when the rotation angle is outside the predetermined range.
4. The head-mounted device according to claim 3 , wherein the control device receives the input signal after a predetermined time elapses when the rotation angle changes from an angle outside the predetermined range to an angle within the predetermined range.
5. The head-mounted device according to claim 1 further comprising:
an acceleration sensor that detects an impact from a specific direction, wherein
the control device treats the impact as the input signal.
6. The head-mounted device according to claim 1 , wherein the output device is a display device configured to display the image.
7. The head-mounted device according to claim 1 , wherein the output device is an audio output device configured to output the sound.
8. A method for controlling a head-mounted device having an output device, including:
detecting a posture of a mounted member mounted on a head of a user;
switching a control mode according to the posture of the mounted member detected, and
performing an output operation of the output device according to the control mode, including:
receiving an input signal related to the switching of the control mode; and
determining whether reception of the input signal is valid according to the posture of the mounted member detected,
wherein
the output device includes a first display device and a second display device,
the detecting includes detecting the posture of the mounted member with a rotation axis that is an axis along a direction in which the first display device and the second display device are aligned, and
the determining includes determining whether the input signal is valid according to a rotation angle formed by a virtual plane orthogonal to a vertical direction and the direction in which the first display device and the second display device are aligned, and a direction orthogonal to the direction in which the first display device and the second display device are aligned in the mounted member.
9. A non-transitory computer-readable storage medium storing a program for controlling a head-mounted device having an output device, the program being configured to perform:
detecting a posture of a mounted member mounted on a head of a user;
switching a control mode according to the posture of the mounted member detected; and
performing an output operation of the output device according to the control mode, including:
receiving an input signal related to the switching of the control mode; and
determining whether reception of the input signal is valid according to the posture of the mounted member detected,
wherein
the output device includes a first display device and a second display device,
the detecting includes detecting the posture of the mounted member with a rotation axis that is an axis along a direction in which the first display device and the second display device are aligned, and
the determining includes determining whether the input signal is valid according to a rotation angle formed by a virtual plane orthogonal to a vertical direction and the direction in which the first display device and the second display device are aligned, and a direction orthogonal to the direction in which the first display device and the second display device are aligned in the mounted member.
