The present invention provides an HMD system for reducing a harmful influence on eyes and for providing enhanced presence. A screen display portion is moved by means of a driving mechanism based on a control signal output from a video playback device. Furthermore, the screen display portion 2 is moved according to how a wearer has reacted. Therefore, an intention of a producer of video software can be reflected in the HMD. Therefore, even in a case of a two-dimensional video without bidirectional property and with inflexible video unfolding, enhanced presence can be reliably provided to the wearer. Because a relationship between positions of eyeballs and the screen display portion is not fixed, the harmful influence on eyesight can be reduced. Furthermore, because the system has a driving mechanism 3, a gyro sensor portion 4, and a control portion 5 for the screen display portion 2, the screen display portion can be moved arbitrarily in any direction and the above control can be carried out accurately.
A head-mounted display controlling method for causing a screen display portion provided in a head-mounted display apparatus to move based on a control signal output from a video playback device, wherein said screen display portion is selectively moved in any one of directions selected from a lateral direction, a vertical direction, and a diagonal direction that is synthesized by said lateral direction and said vertical direction, in response to said control signal from said video playback device, with keeping a distance between a wearer of said apparatus and said screen display portion at a constant value.
A head-mounted display controlling method for causing a screen display portion provided in a head-mounted display apparatus to move based on a control signal output from a video playback device, wherein said screen display portion is selectively moved in any one of directions selected from a lateral direction, a vertical direction, and a diagonal direction that is synthesized by said lateral direction and said vertical direction, in response to said control signal from said video playback device, with keeping a distance between a wearer of said apparatus and said screen display portion at a constant value or moved forward or backward in front of said wearer.
A head-mounted display system for causing an image signal from a video playback device to be displayed on a screen display portion provided in a head-mounted display apparatus and for causing said screen display portion to move based on a control signal output from said video playback device, said head-mounted display system comprising:
A head-mounted display system for causing an image signal from a video playback device to be displayed on a screen display portion provided in a head-mounted display apparatus and for causing said screen display portion to move based on a control signal output from said video playback device, said head-mounted display system comprising:
