Abstract:
1. A vibratory feedback system comprising: a shoe adapted to be secured to a foot of a user; a plurality of force sensors mounted on the shoe, the force sensors configured to sense forces exerted by the foot of the user, the plurality of force sensors comprising at least: a plurality of vibration actuators mounted on the shoe, the vibration actuators configured to provide vibrations to the foot of the user; and a microprocessor affixed to the shoe, the microprocessor coupled to receive data from the plurality of force sensors representing the sensed forces, and the microprocessor programmed to actuate the plurality of vibration actuators to provide (a) a first characteristic vibration to the foot of the user when a sensed force from the heel sensor satisfies a first condition, and (b) a second characteristic vibration different in amplitude, frequency, or location from the first characteristic vibration when a sensed force from the one of the ball sensor or toe sensor satisfies a second condition.
