Resumo(s)
This paper presents a measurement system intended to monitor the usage of walker
assistive devices. The goal is to guide the user in the correct use of the device in order to prevent risky
situations and maximize comfort. Two risk indicators are defined: one related to force unbalance
and the other related to motor incoordination. Force unbalance is measured by load cells attached to
the walker legs, while motor incoordination is estimated by synchronizing force measurements with
distance data provided by an optical sensor. The measurement system is equipped with a Bluetooth
link that enables local supervision on a computer or tablet. Calibration and experimental results are
included in the paper.
