Abstract
A feedback device determines when a person has placed enough weight upon his/her foot to safely take the next step, and then communicate that information to the person via a haptic device on the person's ankle or an audio, visual and/or vibration feedback display on an application on the person's smart phone. Three or more sensors in an insole between the person's foot and shoe determine the force of the person's leg. The force data is sent to a microprocessor where the force data is processed and compared with a baseline. If the processed data exceeds the baseline, the microprocessor will activate the haptic device on the person's ankle to vibrate and/or transmit the processed data through a wireless communications device to an application on a smart phone to activate an audio, visual and/or vibration feedback display on the application. The person will then safely take the next step.
