“…Accelerometers, on the other hand, measure acceleration of the COM and therefore describe the body's attempt to control movement of the COM (Adlerton & Moe-Nilssen 2003). As the two devices measure different metrics they are not necessarily interchangeable, however the correlation of the attempts to maintain balance are good (Mayagoitia et al, 2002;Whitney et al, 2011;Mancini et al, 2012). Therefore it may be possible to obtain sway signatures using the accelerometer method which has distinct advantages over the force plate method for the clinician being smaller, cheaper and not constrained to a specific environment.…”

Main outcome measures:Balance tasks were double leg stance, tandem stance and single leg stance with eyes open and closed. Performance was measured by converting accelerations into path length (PL, length of the sway trace), jerk (jerkiness of sway trace) and root mean square (RMS) of the accelerations.Results: Within-day ICC for PL were excellent (mean 0.78 95%CI 0.68-0.89), with Jerk and RMS demonstrating means of 0.60 and 0.47 respectively. The mean percentage minimal detectable change (MDC) within-day were small for PL (mean 6.7%, 95%CI 5.3-8.1).Between-day ICC were good for PL (mean 0.61, 95%CI 0.50-0.71), but more varied for Jerk and RMS. The mean percentage MDC was small for PL (mean 6.1%, 95%CI 5.0-7.2). No significant differences were determined for measurements between-days for any metric or task. PL had the highest discriminatory value between the 8 tasks. Conclusions:The sacral mounted accelerometer reliably measured balance performance within-and between-days. The PL is the recommended metric as it was the most reliable, most discriminatory and most sensitive to change.

“…Dans des conditions statiques, la mesure de la composante gravitationnelle subie dans chaque axe permet de définir précisément l'inclinaison et l'orientation du capteur. Cette approche est d'ailleurs exploitée dans l'exploration du contrôle postural (Mayagoitia et al, 2002a ;Moe-Nilssen et al, 2002). (Luinge, 2002) En condition dynamique, un accéléromètre triaxial ne pourra mesurer l'accélération subie dans les trois axes avec précision que s'il ne subit pas de rotation.…”

“…Note that our experiments, which involve accelerometer readings based on smart phones located in ones pants pocket, should be able to detect differences in hip movements, if they exist. A final study showed that accelerometer data while standing can tell us something about a person's balance [15].…”

Smart phones are quite sophisticated and increasingly incorporate diverse and powerful sensors. One such sensor is the tri-axial accelerometer, which measures acceleration in all three spatial dimensions. The accelerometer was initially included for screen rotation and advanced game play, but can support other applications. In prior work we showed how the accelerometer could be used to identify and/or authenticate a smart phone user [11]. In this paper we extend that prior work to identify user traits such as sex, height, and weight, by building predictive models from labeled accelerometer data using supervised learning methods. The identification of such traits is often referred to as -soft biometrics‖ because these traits are not sufficiently distinctive or invariant to uniquely identify an individual-but they can be used in conjunction with other information for identification purposes. While our work can be used for biometric identification, our primary goal is to learn as much as possible about the smart phone user. This mined knowledge can be then be used for a number of purposes, such as marketing or making an application more intelligent (e.g., a fitness app could consider a user's weight when calculating calories burned).
