Abstract
In a body mount-type information display apparatus, a display unit (103) is attached to the head of a user, whereas a control circuit unit (105) is attached to the waist or the shoulder. The display unit enables a light beam from the outside to enter the eyes of the user as well as another light beam representing an image produced by the control circuit unit. The user can accordingly observe the image including required pieces of information for the work together with the outside view. This image may be menu-type information or an image in harmony with an object such as a building. In order to display the image in harmony with the object, the direction, the visual angle, and the size of the image are processed according to the positional relationship between the user and the object. Available input means include magnetic and optical pointing devices and a CCD camera for reading a bar code. The control circuit unit that is not attached to the body may be connected with peripheral equipment and used as a desktop computer.
