Shen, Wenqi, Parsons, Ken C. and Vertiz, Alicia M. (1995): The Effect of Stimulus Locus on Perceived Pressure Intensity and Discomfort in Seated Thigh Regions. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. p. 955.

“One of the primary goals in seat design and production is to achieve "ideal" pressure distributions that promote comfortable posture support yet avoid any pressure discomfort. This study investigates the locus effect of regional pressure on perceived intensity and discomfort in seated human thigh, using a category production method. Three subjects took part in the experiment. The test seat cushion was fitted with a vertically moveable circular board of 65 mm in diameter. This stimulus board was driven up and down from cushion surface by an electric-screwdriver, so that the pressure in thigh regions could be changed. A larger wood slice, accommodating the stimulus board, was moved to each required locus. The stimuli were applied at five loci under the seated”
