研究概览
简要总结
The investigators are developing an assistive device, known as multiplexing prism that expands the field of view for individuals with acquired monocular vision (loss of an eye). The investigators will test the efficacy of the prism in improving the detection of colliding pedestrians during a simulated walking task.

研究组 & 干预措施
Detection of colliding pedestrian
Participants will perform a simulated walking task in which surrounding pedestrians will walk towards and make a collision. Participants will respond by pressing buttons to indicate the direction of the colliding pedestrians. Participants will perform the task with and without the multiplexing prism in random orders.
干预措施: Multiplexing Prism (Device)
结局指标
主要结局
Mean response time to detect colliding pedestrian
时间窗: Approximately 3 sessions, up to 3 hours for each session, any time within 4 month period
The investigators will compare the mean response time to detect colliding pedestrians coming from the nasal (same side as the blind eye) and temporal (same side as the seeing eye) visual field with and without multiplexing prism. The comparison will be made between these four: Nasal without prism, Temporal without prism, Nasal with prism, and Temporal with prism.
次要结局
- Pedestrian Detection Rate(Approximately 3 sessions, up to 3 hours for each session, any time within 4 month period)
