  • Head-mounted display controlling method and head-mounted display system
    Patent number: 6633267
    Abstract: 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.

  • Data input/output method and system without being notified
    Publication number: 20020077831
    Abstract: An input method and device allowing a user to operate a computer without being notified is disclosed. A bone conduction microphone is used to pick up a sound produced in an oral cavity of a user. A plurality of registered sounds is previously registered in a database. Each registered sound corresponds to a different computer instruction. When inputting an input sound through the bone conduction microphone, the database is searched for an instruction corresponding to the input sound and the instruction to operate the computer is determined.
