Comparing Accelerometry and Depth Sensing-Based Computer Vision for Canine Tail Wagging Interpretation

Martin, D., Holder, T., Nichols, C., Park, J., Roberts, D., & Bozkurt, A. (2022, December 5). NINTH INTERNATIONAL CONFERENCE ON ANIMAL-COMPUTER INTERACTION, ACI 2022.

By: D. Martin n, T. Holder n, C. Nichols n, J. Park n, D. Roberts n & A. Bozkurt n 

author keywords: Computer Vision; IMU; Animal-Computer Interaction; Interpretability
topics (OpenAlex): Human-Animal Interaction Studies; Rabies epidemiology and control; Veterinary Orthopedics and Neurology
TL;DR: The preliminary findings support that the higher-resolution and continuous interpretations on the dog tail movements and positions can pave the way for assessing their emotional states and designing more appropriate training and play environments. (via Semantic Scholar)

Contact-Free Simultaneous Sensing of Human Heart Rate and Canine Breathing Rate for Animal Assisted Interactions

Holder, T., Rahman, M., Summers, E., Roberts, D., Wong, C.-W., & Bozkurt, A. (2022, December 5). NINTH INTERNATIONAL CONFERENCE ON ANIMAL-COMPUTER INTERACTION, ACI 2022.

By: T. Holder n, M. Rahman n, E. Summers  n, D. Roberts n, C. Wong n  & A. Bozkurt n 

author keywords: human-canine interaction; contact-free physiological sensing; computer vision; signal processing
topics (OpenAlex): Human-Animal Interaction Studies; Non-Invasive Vital Sign Monitoring; Veterinary Pharmacology and Anesthesia
TL;DR: This preliminary effort toward a contact-free approach to facilitate AAI assessment via the physiological sensing of humans and canines using consumer-grade cameras focuses on verifying the technological feasibility of remotely sensing the heart rate signal of the human subject and the breathing rates of the dog subject while they are interacting.
