PROJECTOVERVIEW 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).
HANDMEASURMENTS 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.
