A display system includes an HMD mounted on a head of a user, and a control device coupled to the HMD, the HMD includes an image display unit, with an outside scene being visible, for displaying a display image overlapping the outside scene, and a main control unit for causing an image display unit to display a display image, and the control device includes a touch panel, and a CO control unit for causing a related image related to a display content of the display image to be displayed on the touch panel.

Display system, display method and program

A head-mounted display apparatus includes a display unit configured to display an image overlapping with an external scene, a display control unit configured to control image display on the display unit, a microphone, a first accepting unit configured to accept, by voice recognition of voice input from the microphone, a change of a display state of the image, and a second accepting unit configured to accept, by a method other than the voice recognition, the change of the display state of the image. When acceptance by the first accepting unit is not possible, the display control unit switches to acceptance by the second accepting unit, and changes the display state of the image.

The display system includes a host apparatus and an HMD. The host apparatus includes an image display unit configured to display, an image transmitted from the host apparatus, in which the image processing unit is configured, when detecting that the host apparatus is connected with the HMD, to associate first sensor data from the first inertial sensor with second sensor data received from the second inertial sensor, to recognize a target in the image captured by the camera, to use the second sensor data to perform image processing, and to cause the image display unit to display the image after the image processing in association with the target, when detecting that the host apparatus is not connected with the HMD, to use the first sensor data to maintain an estimation of a state of the target in the outside scene until the host apparatus is reconnected with the HMD.

Display system, display method, and display program for displaying image on head-mounted display

A computer program causes a head-mounted display device including an camera and an image display section capable of being transparent at least against light from a scene to realize functions of: an image setting function of displaying, with the image display section, a marker image that is capable of being perceived to be at least partially aligned with a real marker; a detection function of detecting the real marker from an image captured with the camera; a parameter setting function of setting at least one parameter for allowing an AR object displayed with the display section to be perceived to correspond to an object in the scene; a determination function of determining whether a user's head is in a substantially static condition, and a collecting function of collecting, from the image or another image captured with the camera, calibration data that is to be used in the parameter setting function in response to an instruction, in the case where the user's head is determined to be in the substantially static condition by the determination function.
