title: Cross validation of measures of handle/human fit.
abstract: The problem of measurement of effectiveness of handle design was addressed directly by scales. Ratings on several subjective scales were used and compared with maximum force exertion capabilities and grip force efficiency. Three of the handles were selected by overall preference ranking and tested using the Point of Subjective Equality (PSE) measure proposed by Hsia and Drury (1986). Factor analysis revealed two orthogonal factors, one related to overall preference and one related to strength. The PSE measure failed to give significant results.
