ABSTRACT:
A data entry device having five keys, not in one plane, is held in and operated by one hand. Each key has two "on" positions and one "off" position. By using a single key or chord of keys to form characters, a surplus of possible combinations is generated. Because it is grippable and requires only one hand to operate, the user can utilized it while simultaneously walking, writing, reading, commuting, using a phone, holding a conversation, or engaging in related and unrelated activities.
