Title:
FALL RISK ASSESSMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/262669
Kind Code:
A1
Abstract:
A human balance sensor for assessing the risk of the user falling includes a transparent glass plate, a latex sheet located on the top surface of the glass plate, a light source located so as to inject light into edge of the glass plate and a high resolution camera located below the glass plate so as to capture light diffused from the glass plate when pressure is applied thereto by the user's foot. Based on the principle of Frustrated Total Internal Reflection (FTIR), when user stands with his feet on the glass plate a condition of total internal reflection is eliminated at pressure locations due to the pressure from the feet, and diffused light passes from the bottom surface of the glass plate and forms a haptic image of the contact area of the feet which can be analyzed over time to determine the user's ability to balance, and hence their risk of a fall.
