Study 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
Primary Outcome
Stride length will be measured using the Zeno Walkway system, an electronic, pressure-sensitive mat connected to a PC that automates the measurement of spatial and temporal aspects of gait. The walkway's high-resolution sensors capture real-time data as participants walk across it. Each participant will walk on the instrumented mat for approximately 30 minutes, allowing for detailed analysis of stride length. Mean stride length (in meters) will be calculated from multiple trials to assess change
