Conditions
Summary
The objective of this study is to study a novel device designed to aid patients with impaired vision to safely navigate their environment. Subjects for this study will be individuals with normal vision, either with or without correction. The subjects will wear a device to simulate impaired vision and will be asked to walk a path with randomly placed obstacles during two trials. One of the trials will consist of the subject wearing the simulator alone. The other trial will consist of the subject wearing the simulator and the study device. The study device is designed to be worn by the study subject and will emit tones to indicate obstacles in the environment as the subject walks on the path with random obstacles. The tones will indicate that there is an obstacle in the individual's path and will increase in intensity as the subject moves closer to the object.Invest

Interventions
The device features many parametric speakers housed in a plastic case. The parametric speakers emit directional sound waves that return to the source with varying wavelengths depending on the distance of the surrounding objects. The device is designed to be worn by the subject either using a lanyard on the subject's neck, or on the subject's wrist.
