Abstract
Vibratory feedback systems and methods are disclosed. A vibratory feedback system includes a shoe adapted to be secured to a user's foot, a plurality of force sensors and vibration actuators mounted on the shoe, and a microprocessor affixed to the shoe. The force sensors are configured to sense forces exerted by the user's foot. The vibration actuators are configured to provide vibrations to the user's foot. The microprocessor is coupled to receive data from the plurality of force sensors, and is programmed to actuate the plurality of vibration actuators to provide a first characteristic vibration to the user's foot based on the sensed forces. A method of improving the gait of a user includes enabling the user to ambulate with the vibratory feedback system secured to the user's foot, and providing a first characteristic vibration to the user's foot based on the sensed forces using the vibratory feedback system.
