Abstract

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.

Claims

1. A finger movement actuated communication device individually responsive to thrust and push motions of at least one finger of a person'"'"'s hand with reference to the metacarpal portion of the hand, said device comprising:

a metacarpal reference attachment member adapted to be secured to the back of the hand;

a first collar-like attachment member adapted to be secured to the proximal segment of the one finger so as to follow motion of the proximal segment;

a second collar-like attachment member adapted to be secured to a segment of the one finger beyond the proximal segment so as to follow motion of the middle segment of the one finger;

a first extendable switch assembly mechanically linking said metacarpal reference and said first collar-like attachment members such that said first extendable switch assembly lengthens and shortens as the proximal finger segment pivotally moves with reference to the metacarpal portion of the hand in a thrust motion, said first extendable switch assembly including a first switch element having two states, said first switch element being in one of its states when said first extendable switch assembly is lengthened and in the other of its states when said first extendable switch assembly is shortened; and

a second extendable switch assembly mechanically linking said first and second collar-like attachment members such that said second extendable switch assembly lengthens and shortens as the middle finger segment pivotally moves with reference to the proximal finger segment in a push motion, said second extendable switch assembly including a second switch element having two states, said second switch element being in one of its states when said second extendable switch assembly is lengthened and in the other of its states when said second extendable switch assembly is shortened;

whereby said first switch element responds to thrust motions of the finger and said second switch element responds to push motions of the finger.

2. A communication device in accordance with claim 1, which includes four sets of first and second collar-like attachment members and first and second extendable switch assemblies, one set for each finger, thereby providing eight switches which can be selectively operated by one hand in predetermined combinations.

3. A communication device in accordance with claim 2, wherein one of said second collar-like attachment members is adapted to be secured to a segment of the forefinger of the person'"'"'s hand and carries a switch actuator positioned for activation by a thumb.

4. A finger movement actuated communication device in accordance with claim 1, which includes selectively controlled tactile stimulation elements within said collar-like attachment members to enable communication to the operator of said communication device.

5. A finger movement actuated communication device in accordance with claim 4, wherein said tactile stimulation elements comprise vibrators.
