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 ...
Classifying daily and sports activities invariantly to the positioning of wearable motion sensor units

Barshan, Billur; Yurtman, Aras (IEEE, 2020)

We propose techniques that achieve invariance to the positioning of wearable motion sensor units on the body for the recognition of daily and sports activities. Using two sequence sets based on the sensory data allows each ...
