Abstract
An apparatus for creating and tuning haptic feedback is provided. The apparatus includes (A) a brace with first and second portions, (B) a vibrotactile actuator, coupled to the first portion of the brace, configured to apply haptic stimulations to a user, and (C) a linear actuator, coupled to the second portion of the brace, configured to (i) obtain a signal generated based on information about the user's body at a target location of the user and (ii) adjust a tension of the brace according to the signal. In some embodiments, the apparatus also includes one or more sensors configured to generate the information about the user's body at the target location. Furthermore, a controller may be configured to: (i) generate the signal based on the information about the user's body at the target location generated by the one or more sensors and (ii) provide the signal to the linear actuator.
