When was the first graphical touchscreen point of sale invented?
In 1986 Gene Mosher assembled the Atari ST520 with a 12" color display, a MicroTouch capacitive touchscreen and a Star Micronics DP8340 printer to create the first graphical touchscreen point of sale software and computer system. He named it 'ViewTouch' and first installed the POS system in The Mill Camp Restaurant on Q Street in Springfield, Oregon in July, 1986. ViewTouch POS was first demonstrated publicly at the ComDex (Computer Dealer Exposition) in Las Vegas in November, 1986, and in March, 1987 at the Canadian National Restaurant Exposition in Toronto. The POS system's graphical interface was created by a comprehensive collection of 'buttons' or widgets which were designed to mimic all of the keys which could be found on an electronic cash register as well as drive the interface to all of the various management functions built into the software, many of which Mosher had created as far back as 1977 when writing POS software on his Apple II computer for the restaurants he operated in Norfolk, Virginia and in Syracuse, New York. These were carried forward into the graphical touchscreen POS software introduced in 1986 and included sales history, time clock, expense management, labor cost accounting and remote printing to the food preparation area of his restaurants. The ViewTouch POS system was the first documented computer system to make use of a system of colorgraphic touchscreen widgets which could be directly manipulated by end users and which comprised a complete solution package for the hospitality vertical market.
