The People
Company Background
In 2000, George Forester invited Jerry Wilski to join him in an adventure to develop and market George's original invention of the keypad which eventually became the EkaPad.
R&D History
In the 1980s, George was playing around with the idea of a pocketable computer. A main feature could be a keypad on the backside, played with the eight fingers as the palms of the hands held the computer between them. George was an amateur musician and recorder player and he easily envisioned how this keying could work. See EkaPad Design white paper 2006
More research and development history can be found at the EkaPad R & D History pages.
