Information Capacity of the Human Motor system 

   Literature Review

Information theory was originated by communications engineers in telephone Laboratories (partly 1928, €hanon 1948), their interest being tone problems of how quickly and accurately one can send messages over not sq  tel  ephone ltnes . From thts expe i ment they devel oped  the  tnf°o  ma— tton theor'y as a means of dt scusstng suchlike prob\ ems .

Informatt on theory  Is an  attempt  to  expl atn  communtc att on  In  a precise  mathemattc at  Fashi on .                                                 It Is a mathemattc at tec hnt que f°or' mea.so r— Ing  the        ef'f'ect Oneness   of   stgn  tr•ansmi sst on In   a  man made system .                     What
