Using personal computer to measure vertical deviation from a prescribed : horizontal track

Abstract EN

This paper aims at measuring the vertical deviation of the hand while conducting a horizontal movement, in an attempt to show the relationship between deviation and age, and deviation and movement duration.

This necessitates the investigation of hand movements of subjects with varying ages.

A light pen is used for capturing the signal induced by the hand movements.

Deviation is found to be dependent on duration and age of subject.

Young and old aged subjects show large deviation in contrast to middle-aged subjects.

Correlation factor for deviation and duration is equal to 0.86 for all subjects.Correlation factor for deviation and age is > -0.96 for young subjects and is > 0.96 for old subjects.

Correlation factor for duration and age is > -0.99 for young subjects and is > 0.98 for old subjects.

Two mathematical formulas are presented; the first expresses the dependence of deviation on age while the other expresses the dependence of duration on age.
