Exploring Low Cost Non-Contact Detection of Biosignals for HCI

In an effort to make biosignal integration more accessible to explore for more HCI researchers, this paper presents our investigation of how well a standard, near ubiquitous webcam can support remote sensing of heart rate and respiration rate across skin tone ranges. The work contributes: how the webcam can be used for this purpose, its limitations, and how to mitigate these limitations affordably, including how the skin tone range affect the estimation results.

Introducing Vibration for use in Interaction Designs to support Human Performance: A Pilot Study

While vibration is a well-used output signal in HCI as part of haptic interaction, vibration outside HCI is used in many other modes to support human performance, from rehabilitation to cognition. In this late breaking work, we present preliminary positive results of a novel protocol that informs how vibration might be used to enrich HCI interventions for aspects of both health and intellectual performance. We also present a novel apparatus specifically designed to help HCI researchers explore different vibration amplitudes and frequencies for such applications.
