In fuzzy control ,according to the actually obstacle position and the angle between the target orientation and the robot’s direction of movement ,we give the reaction rules of the robot.

A novel algorithm is proposed in this paper to detect anomalous human behaviors based on motion directions.

And the motion direction has significant effect on the perception of motion.

Point in polygon testing based on normal direction;

This paper present a new method which improve DMU along normal direction,this method can make non-effective DMU to be effective quickly and decrease the variation of input and output.

The study collect the latest research results both at home and abroad, and elaborate from the development status of the effectiveness evaluation research on fitness club member\'s physical exercise methods and amount of exercise.
