Algorithm 3 Algorithm for pattern matching.

Input:$PT1,PT2,PT3,PT4,PT5,PT6,PT7,PT8$

Input: hand pattern as T at current frame

1: for i each pattern of templates do

2:  calculate $HP=T\wedge (PT1\vee PT2\vee ..PT8)$

3:  if $HP$ = 1 then

4:   set pattern match

5:  else

6:   set pattern does not match

7:  end if

8: end for
