Field of Invention:
Present invention relates to a device for assisting a disabled person, for converting commands given by fingers. More particularly, the present invention relates to a device for assisting mute and paralysed people having an interactive voice.
Background of Invention:
In recent years, for human computer interactions hand gesture recognition is used mostly. They play an important role in gaming and control application i.e. 3-D mouse, Tele-robotics & virtual reality controlling. Rather than this, it is also used in those applications which aid the physically challenged community as dumb and paralyzed people. So, primary requirement for conversion of sign people to speech is Hand/Nail gesture recognition. Hand/Nail gesture recognition invention is very useful for dumb and paralyzed people, it can also be used by the patients with of paralyzed as they couldn’t speak.
Currently the existing speaking system for dumb and paralyzed person uses, separate sensors used for monitoring for each and every system. In one system, the messages are transferred by wireless and in another system, the messages are transferred by Bluetooth/WI-FI/IOT or similar modules. These systems are used by short distance communication and in case data’s are got

loss in the wireless transmission lines. In existing all systems they are used only flex sensors. By this flex sensor the restricted movements of paralyzed (stroke) patients cannot flex their hand or finger.
US 4905001 discloses 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.
As per claim 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.
U.S. 4,458,238 discloses a hand-held data entry unit including a handle with four pushbutton switches respectively corresponding to four rows of an attached matrix type display which is scanned during operation and visually observed by the user. Thumb switches are also included which act as "shift" keys. As per the abstract- A data entry unit has a board on which a matrix of

cells are arranged, for example, twelve columns by four rows. When turned on, each column is sequentially illuminated in a continuous cyclic fashion. The illumination of a column indicates that the data associated with each of the four cells in that column is enabled. A handle attached to the board has at least four switches on it that can be readily manipulated by four fingers of the user's hand. When a column is illuminated, closing one of the four switches will complete the selection of the data in the corresponding one of the four cells of the illuminated column. This data may be stored of displayed or both. Each cell can be designed to correspond to two separate items of data, such as lower and upper case letters. In such a case, a further thumb actuated switch in the handle provides user selection for one of the two data phases of the cell.
US 3831296 discloses a method and system for communicating with the blind and deaf person produces a sequence of electrical impulses corresponding to the characters on a typewriter keyboard. The impulses are employed to selectively actuate corresponding stimulators positioned on a surface areas of the handicapped person''s body and arranged generally in the pattern of such keyboard. Each stimulator, upon being actuated, stimulates a portion of such area of skin corresponding to the character of the keyboard. A specific example of apparatus employed in the above method and system includes a

typewriter terminal connected to a pair of gloves having a plurality of stimulators embedded therein.
As per the Summary of US 3831296, the invention provides effective rapid communication with a deaf and blind person, either with a similarly handicapped person or a nonhandicapped person when such persons are in the presence of each other or are distant from each other. The invention utilizes a plurality of tactile stimulators at spaced locations on an area of the body of a blind and deaf person which are arranged generally in a predetermined pattern, and preferably in the pattern of a typewriter keyboard. The backs of the hands of such person constitutes a suitable area and the stimulators may be attached to a pair of gloves which are put on when it is desired to communicate. The handicapped person is taught that each location of a stimulator represents a different alphanumeric character, and that the arrangement of characters corresponds with the predetermined pattern such as the keyboard arrangement of a standard electric typewriter. The stimulators may, for example, be electrically actuated and electrical impulses for actuating the stimulators can be produced by striking corresponding keys on a typewriter keyboard having electric contacts which are closed when the respective keys are struck. These impulses can be applied to the stimulators through a connecting cable so that the depression of each key actuates a single stimulator. With such a system a nonhandicapped person can

communicate with a blind and deaf person by typing a message on the keyboard of an electric typewriter forming part of the system. The handicapped person can respond to the nonhandicapped person in the same manner by touch typing on the same or a similar typewriter keyboard. It is also possible using dual units for one blind and deaf person to rapidly communicate with another blind and deaf person. The use of the standard typewriter keyboard arrangement for locating the stimulators on the hands of the handicapped person has the advantage of avoiding encoding problems, but it is apparent that other arrangements of keys on a keyboard and a corresponding arrangement of the stimulators on the hands or other body surface of the handicapped person can be employed. Once the basic keyboard arrangement is learned by the handicapped person, anyone may communicate with him merely by typing on a keyboard.
