Title :
SAM: an improved input device
Abstract :
SAM allows people to communicate by sending Morse code with a single switch. Unlike most Morse code input devices, SAM allows extreme latitude in the timing of dots and dashes. This makes it usable by people who have trouble mastering the precise timing of conventional Morse code. SAM is portable and inexpensive-it costs about $50 to build and runs on four `AA´ batteries. Because of its large self-contained message display, SAM can be used stand-alone. SAM can also be used as an interface to a personal computer
