Kim, Dae Shik; Emerson, Robert Wall; Curtis, Amy – Journal of Visual Impairment & Blindness, 2009
This study compared the drop-off detection performance with the two-point touch and constant contact cane techniques using a repeated-measures design with a convenience sample of 15 cane users with visual impairments. The constant contact technique was superior to the two-point touch technique in the drop-off detection rate and the 50% detection…
