Simulated Walking With Multiplexing Prism for Field Expansion in Monocular Vision

Monocular Visual Confusion for Field Expansion

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.

Inclusion Criteria:

• No medical health issues such as seizures, motor movements problem
• Loss of vision in one eye (less than 20/200) for >1 year
• Visual acuity of the seeing eye: Better than 20/32 visual acuity with correction
• No visual field defect in the seeing eye (nasal field of at least >45degree)

Exclusion Criteria:

• Patients with any physical or mental disabilities, including cognitive dysfunction, balance problems, or other deficits that could impair their ability to respond to the stimuli presented in this study will be excluded
• Any person with a history (such as pacemaker use or photosensitive epilepsy)
• Any person with motor movements problem (e.g., unable to use extremities)
