Assisting people with visual impairments in aiming at a target on a large wall-mounted display ?
A directional vibrotactile feedback for people with visual impairments is proposed. Two experiments for target-aiming tasks by blind participants are conducted. Converting a 2D search space to linear searches improves target-aiming performance. Augmenting speech with vibrotactile feedback improves target-aiming performance.
