Description:
Human laterality is considered to be one of the most important issues in human factors engineering. In this context, hand anthropometric data can help in the proper designing of hand tools for better efficiency and less human fatigue. In the present study hand dimensions of right- and left-handed individuals were collected based on Jordanian subjects. Results indicated that there were significant differences in hand measurements between right- and left-handed individuals as well as between males and females subjects. Percentile values for right-handed, left-handed, males and females subjects were also calculated. It was found that the hand tools should be designed separately to fit left and right handers. Further, where precise control is needed, hand tools should be designed separately to fit the hand of males and females. Relevance to Industry: Hand anthropometric data have indicated differences between right- and left-handed individual and between males and females. This finding should affect the hand tool design. Accordingly, designers of the hand tool for Middle East market in general and for Jordan markets in particular should take these findings into consideration.
