A reflective-type display device based on phase change materials is attractive because of its ultrafast response time and high resolution compared with a conventional display device. This paper proposes and demonstrates a unique display device in which multicolour changing can be achieved on a single device by the selective crystallization of double layer phase change materials. The optical con...

This paper proposes a tactile display mouse providing both pin-array type tactile display and thermal display. Micro shape and vibrotactile stimuli can be generated by pin-arrayed tactile display and various planar distributed patterns can be also displayed such as Braille cell patterns. Temperature and thermophysical property of object can be displayed by the thermal display device that is com...

The limitations of palmtop computers are their display size and pointing mechanisms. This makes it difficult to use them for direct manipulation of very large objects, such as World Wide Web (WWW) pages, newspapers, maps, and documents that require a large display. This paper describes a new palmtop computer with a built-in mouse on the underside of the computer. When a user moves the computer ...

A simple modification of Horn's circle drawing procedure yields a disk generator for a class of graphic devices capable of drawing rectangular areas. Another variation produces a disk a scan-line at a time allowing it to be drawn at the refresh rate of the display. The calculations involve only additions and binary shifts.
