The KoalaPad is a graphics tablet produced from 1984 by U.S. company Koala Technologies for several early 8-bit home computers, including the Apple II family, TRS-80 Color Computer (TRS-80 Touch Pad), Atari 8-bit family, and Commodore 64, as well as for the IBM PC. Originally designed by Dr. David Thornburg as a low-cost computer drawing tool for schools, the Koala Pad and the bundled drawing program, KoalaPainter, was very popular with home users as well (KoalaPainter was called KoalaPaint in some versions for the Apple II, and PC Design for the IBM PC). A program called ''Graphics Exhibitor'' was included for creating slideshow presentations from KoalaPainter drawings. ==The KoalaPad== The pad was four inches square (i.e. roughly 10×10 cm) and mounted on a slightly inclined base with the back of the pad higher than the front. At the top, "behind" the pad, were two buttons. The pad hooked into the computer using the analog signals of the joystick ports (the so-called "paddle" inputs), which meant that it had a fairly low resolution and tended to jostle the cursor if moved during use. Instead of the drawing stylus, the pad could as easily be operated by the user's fingers for less precision-demanding work, such as selecting between menu items (i.e. using the pad as a kind of "indirect touch screen"). The top-mounted buttons tended to be somewhat frustrating to use, as the user had to "reach around" the stylus to push the buttons in order to start or stop drawing. A similar tablet from Atari, the "Atari CX77 Touch Tablet", addressed this with a built-in button on the stylus,〔(Best Electronics Atari Controller Quick Reference Guide )〕 which some enterprising users adapted for use with their KoalaPad. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「KoalaPad」の詳細全文を読む スポンサード リンク
