Abstract
A feedback device for measuring balance related information, and for producing a stimulation of the skin that encodes that information in a way that is useful to the wearer of the device. At least one sensor detects balance information and transmits at least one balance information signal to a signal processing subsystem. The signal processing subsystem converts the received balance information signal into at least one stimulation control signal. The signal processing subsystem then transmits the stimulation control signal to at least one stimulator, which provides stimulation to a wearer of the device reflecting the stimulation control signal received from the signal processing subsystem.
Claims20
A system for improving balance control, the system comprising:
- a. at least one sensor positionable against a limb of the user, wherein the at least one sensor is configured to generate user balance information signals and transmit the user balance information signals;
- b. a signal processing subsystem, the subsystem configured to receive the user balance information signals and generate balance control signals comprising temporal and spatial information reflecting an amount of force applied to the at least one sensor;
- and
- c. at least one stimulator configured to be responsive to the balance control signals to provide stimulation when the amount of force exceeds the predetermined force threshold, thereby providing feedback to the user.
A system for improving balance control, the system comprising:
- a. at least one sensor positionable under a user's foot, the at least one sensor positioned to sense an amount of force applied to the at least one sensor, wherein the at least one sensor is configured to generate, during user stance and dynamic activities, user balance information signals and transmit the user balance information signals;
- b. a signal processing subsystem, the subsystem configured to receive the user balance information signals, compare the user balance information signals to a predetermined temporal or spatial force threshold, and generate, based on the user balance information signals and the predetermined force threshold, balance control signals comprising temporal and spatial information reflecting the amount of force applied to at least one sensor;
- and
- c. at least one stimulator configured to be responsive to the balance control signals to provide stimulation during the user stance and dynamic activities when the amount of force exceeds the predetermined force threshold, thereby providing feedback to the user to allow corrective action to reduce or eliminate skin damage.
A method of improving balance control, the method comprising:
- a. sensing, with at least one sensor, on a user's foot an amount of force applied to the at least one sensor,
- b. generating, during user stance and dynamic activities, user balance information signals as a function of the amount of force;
- c. transmitting the user balance information signals to a signal processing subsystem;
- d. comparing, with the signal processing subsystem, the user balance information signals to a predetermined temporal or spatial force threshold;
- e. generating, based on the user balance information signals and the predetermined force threshold, balance control signals comprising temporal and spatial information reflecting the amount of force applied to the at least one sensor;
- and
- f. providing stimulation to the user during the user stance and dynamic activities based on the balance control signals when the amount of force exceeds the predetermined force threshold, thereby providing feedback to the user to allow corrective action to reduce or eliminate skin damage.
