If Controls in the Catalogs Just Won't do,Then Top-Down Design is Right for You

Abstract

Any human-artifact interface ultimately depends on the characteristics of available controls, displays, and other components. Human factors' role is often merely that of performing hardware trade-offs and making recommendations. This consumer's approach deviates from human factors' proper function of initiating and contributing optimum control/display designs. In line with the latter, a new hand control was designed for use in environments where off-the-shelf controls were found to be inadequate.
