• Modified version of Schouten and Verfaillie’s (2010) technique • Varying field of view angle, FOV (= varying camera distance) • Interleaved staircases to measure 75% FTV and 25% FTV thresholds • Camera adopts three different heights above ground: • head – Camera at walker height • centre – Camera at mid-walker height • feet – Camera at floor level • 40 trials per staircase, 240 trials total (3*2*40 trials) METHOD
