Abstract
An example system coupled to a rollator for monitoring usage of the rollator, includes a grip assembly and/or a hip sensing assembly. The grip assembly includes a first sensor configured to detect a force applied to the first sensor. The hip sensing assembly includes a second sensor configured to measure a distance between the second sensor and a hip of the user positioned with respect to the rollator. A microcontroller is electronically coupled in signal communication with the first sensor, the second sensor, and a feedback circuitry. When the force applied to the first sensor exceeds a first threshold, the microcontroller activates the feedback circuitry to generate a first response indicating that the first threshold has been exceeded. When the distance exceeds a second threshold, the microcontroller activates the feedback circuitry to generate a second response indicating that the second threshold has been exceeded.
