Abstract

This paper presents a real-time and non-destructive method for capturing finger hand movement via a hand glove. From previous research, a major limitation appears to be limited portability due to presence of cloth support and less accuracy due to poor calibration (a tedious, non-automatic process). The proposed finger hand movement capturing system is capable to detect finger hand movement via hand glove that is attached with flex bend sensor at each finger hand respectively. The calibration of the hand glove is done automatically when wearing the hand glove by using linear regression method. The data from the hand glove can be stored and monitored at real time via GUI system. The finger hand movement is captured based on the flex sensor output as the resistance increase proportionally when the sensor is flexed. The output voltage of the flex sensor represents the degree of the finger’s bending. A prototype of the hand glove attached with the flex sensor has been developed and the result shows that the flex sensor has more than 90% linearity on the performance of the hand glove. In addition, the wireless communication used in this system reduced cables attached to the hand glove which give more portability in using the system.
