Activity recognition invariant to sensor orientation with wearable motion sensors

Yurtman, A.; Barshan, B. (MDPI AG, 2017)

Most activity recognition studies that employ wearable sensors assume that the sensors are attached at pre-determined positions and orientations that do not change over time. Since this is not the case in practice, it is ...
Activity recognition invariant towearable sensor unit orientation using differential rotational transformations represented by quaternions

Yurtman, Aras; Barshan, Billur; Fidan B. (MDPI AG, 2018)

Wearable motion sensors are assumed to be correctly positioned and oriented in most of the existing studies. However, generic wireless sensor units, patient health and state monitoring sensors, and smart phones and watches ...
