The purpose of this project is to redesign a common garden tool with close
attention to human factors’ considerations. The first phase of this project entails
gathering anthropometric data relevant to the specific tool, task, environment, and
user. For the hose nozzle, physical user interaction is limited to the hand;
therefore, several measurements pertaining to the dimensions of my hand were
recorded and compared with anthropometric data from the US (see Dreyfuss).
All measuremnts are taken with calipers in mm. The data are
compared to data for the 1st, 50th, and 99th percentiles for men
from the US. My dimensions are in green.

To measure the maximum grip diameter, the hand is
placed around a cone and lowered until only the thumb
and middle fingers touch (Pheseant 250). To simplify
this process, I created a circle with my thumb and
middle fingers and measured the diameter. The
maximum functional spread is taken by
“gripping a wooden wedge with the
tip end segments of the thumb
and ring fingers” (250). My
dimensions are in green.

After analyzing the data and comparing with both estimated measurements and actual data from the
United States and the United Kingdom, it is clear that egocentric, ethnocentric, and gerocentric design are
limited in application. While my own dimensions may be a useful starting point, to extrapolate my data
for all users would be an oversimplification. It is also clear that body dimensions are not
linearly correlated, even for a single isolated appendage such as a hand.
Furthermore, there are instances where I myself do not fit the 5th
to 95th percentile range, which serves to indicate the limits of that
rule as well. Essential measurements for the hose nozzle include
the hand, palm, and finger lengths as well as the grip diameter.
