Abstract
This study investigated the following factors affecting the measurement accuracy of the seat pressure measurement system made by TekScan, Inc.: (a) contact time; (b) contact area; (c) the amount of force applied on the pressure mat at the time of calibration and at measurement; and (d) the consistency of contact time before calibration and measurement, and the time interval between calibration and measurement. Results show that the above factors significantly affect the accuracy of measurement. The measurement error can be limited by controlling the contact time for both calibration and measurement to 2 minutes, and controlling the contact area and applied force equally at calibration and measurement.
