Algorithm for detecting late swing using only acceleration in the direction of travel of the foot

Nihon Kikai Gakkai ronbunshu, 2022
If an abnormality occurs while walking and a fall occurs, elderly people with reduced muscle strength and bone density may become bedridden in the worst case due to a fracture of the neck of the femur. The purpose of this study is to develop an algorithm

Assessment of sleep‐disordered breathing using a non‐contact bio‐motion sensor [PDF]

Journal of Sleep Research, 2012
SummaryObstructive sleep apnoea is a highly prevalent but under‐diagnosed disorder. The gold standard for diagnosis of obstructive sleep apnoea is inpatient polysomnography. This is resource intensive and inconvenient for the patient, and the development of ambulatory diagnostic modalities has been identified as a key research priority.

Audio signal analysis in combination with noncontact bio-motion data to successfully monitor snoring [PDF]

2014 36th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2014
This paper proposes a novel algorithm for automatic detection of snoring in sleep by combining non-contact bio-motion data with audio data. The audio data is captured using low end Android Smartphones in a non-clinical environment to mimic a possible user-friendly commercial product for sleep audio monitoring.

Multi Agent/Object Simulation in Human Swimming

Journal of Biomechanical Science and Engineering, 2010
In human swimming, there are many situations in which the target of the analysis is not only the swimmer but also other swimmers or other equipment, such as synchronized swimming by multiple swimmers, swimming with fins, and so on.

A PCA-based bio-motion generator to synthesize new patterns of human running

PeerJ Computer Science, 2016
Synthesizing human movement is useful for most applications where the use of avatars is required. These movements should be as realistic as possible and thus must take into account anthropometric characteristics (weight, height, etc.), gender, and the performance of the activity being developed.
