Abstract: A portable voice communication device such as a cellular telephone incorporates a virtual image display module so as to provide a virtual image of displayed information that is viewable while the user is communicating via the phone. The virtual image display module is movably mounted on a hand held frame so that it can be moved from a compact storage position to an extended in-use position. Moreover, a linkage between the virtual image display module and an earphone speaker module increases the distance between the two modules to accommodate a comfortable viewing distance when the earphone is positioned adjacent a user's ear.

Abstract: A head mounted display system includes an image display module for generating a virtual image mounted on a frame to be worn on a user's head. The frame includes a front portion and a pair of temples that are adjustable in length and in tension to accommodate users of various head sizes. The system is further foldable for storage with an eye blocker forming a protective cover for the optical surface of the image display module when it is not in use. A microphone is incorporated into the housing of the image display module to pick up a user's voice and provide hands free operation of the head mounted display system.

Abstract: A monocular head mounted display system that is convertible between a right eye display system and a left eye display system includes a generally symmetrical frame. A flexible support arm moveably mounted on the frame, supports an image display module. The image display module includes a display and optical system to project an enlarged image at a distance from the user. With the frame in a first position with the image display module below the frame, the image is viewable by a user's right eye. The system is converted by moving the support arm so that the display module is above the frame in the first position and then the frame is flipped over to an inverted position with the display module again below the frame but the image viewable by the user's left eye.
