Abstract :
FrogPad Inc. has developed a keyboard that can be used with one hand. The keyboard - designed for use with desktop computers, cell phones, or PDAs -could help mobile workers who don´t always have both hands free or disabled people who have the use of only one hand. FrogPad works with various techniques to give its 20 keys all of the functionality of a traditional keyboard and even that of a 10-key phone or calculator.
