Disclosed are various forms of hand-held communication devices which serve as alternatives to a keyboard and which, in addition, allow the user to receive communications via the sense of touch. Although not so limited, the device is well-adapted for use by persons who are speechless, deaf and speechless, or even blind, deaf and speechless. The present invention provides particularly compact and efficient finger movement actuated communication devices for individually responding to thrust and push motions of at least one finger of a person's hand. Thus, each finger can operate two switch elements, and the four fingers of a person's hand can operate eight switch elements in predetermined combinations suitable, for example, for communication in a binary code. In a first disclosed embodiment, a handle-like body supports eight switch actuators arranged as four pairs, with each of the pairs corresponding to a particular finger. The two switch actuators are positioned for selective activation by distal and proximal segments of a single finger. In a second disclosed embodiment, four switch actuators are provided for actuation by the fleshly portions of a person's fingertips. Each of the switch actuators supports two distinct types of movement, pushing and sliding, and corresponding operate a pair of switch elements. In a third disclosed embodiment, collar-like rings are worn about the proximal and middle segments of the user's hand. Relative motion between the collar-like rings and a wrist harnass is sensed in order to respond to thrust and push motions of the fingers.
