Abstract: A virtual reality display system 10 comprises a first display, a second display and a third display, the first display having a three-dimensional display volume 18 and including a plurality of projectors 12, 14, 16 for projecting a three-dimensional image 102, 104, 106, 108 into the display volume 18, the second display including at least one substantially translucent display screen 20, 22, 24, 26, 28 and means for displaying an image on the display screen, and the third display being a holographic display.

Abstract: A three-dimensional display system comprises a display housing and a plurality of projectors for projecting two-dimensional images into a space, each projector having means to adjust the distance between the projector and the projected image, and each projector being pivotally mounted to the display housing, for adjusting the horizontal and vertical position of the projected two-dimensional image with respect to the projector. The display provides a high-resolution, three-dimensional multi-coloured image which can be touched safely by the viewer. The display may be respond to physical objects in the display area by altering the image. The display may be used to operate a computer and browse the world wide web.

Abstract: A three-dimensional display system (10) comprises a display housing (24) and a plurality of projectors (12) for projecting two-dimensional images (102) into a space, each projector (12) having means to adjust the distance between the projector (12) and the projected image (102), and each projector (12) being pivotally mounted to the display housing (24), for adjusting the horizontal and vertical position of the projected two-dimensional image (102) with respect to the projector (12). The display provides a high-resolution, three-dimensional multi-colored image which can be touched safely by the viewer. The display may be respond to physical objects in the display area by altering the image. The display may be used to operate a computer and browse the world wide web.

Abstract: A navigation device includes a route generator, a travel log recorder, a traveled route generator, and a display module. The route generator is used for generating a route from a current position to a destination based on predetermined mapping data when receiving a route request. The travel log recorder is used for recording a traveled log of the navigation device before receiving the route request. The traveled route generator is configured for generating traveled route information according to the traveled log recorded in the travel log recorder when receiving the route request. The display module is used for displaying the route and the traveled route information simultaneously for guiding a user to the destination. A related navigation method is also provided.

Abstract: A mop includes top assembly containing a frame and base assembly; a first shaft and a second shaft pivoted to the frame with two linking members; a cleaning member mounted to either shaft with one end of the cleaning member connected to another shaft to exercise linked displacement between both shafts by driving the shaft; the base assembly includes a base plate incorporated to the frame at a bottom of the frame; and a pad connected below the base plate for the cleaning member to travel along exposed are of the pad; the cleaning member in operation being supported by the pad creates larger working area and firmly contacting a floor to provide better cleaning results.
