Abstract
Mobiles are getting developed with advanced sensors and increasing computing power extending their capability for ubiquitous studies of human physical and cognitive behavior and capabilities. Physiological hand tremor is inherently present in all people between the frequency ranges of 6–12 Hz limiting the accuracy of their hand precision tasks. The objective of this study is to evaluate the use of accelerometry sensors in the smartphone as a quantitative metric to measure hand tremors. In this study, a smartphone was held in prone position of the hand with forearm and wrist supported. Simultaneous measurements were conducted on the smartphone and in a laboratory-grade accelerometry system for the benchmark. Both time domain and frequency domain analyses were performed on the measured data on the X, Y and Z-axis. It was observed from the results that smartphones could likely be used in behavioral studies and real-time clinical evaluations of both resting and action tremor assessments.
