Past Webinar – No One Left Behind: Building Low-Cost Wearables for Low-Income Communities, Longfei Shangguan

Abstract: Wearable devices such as Apple Watch and Fitbit wristband allow users to track their health statistics around the clock. They have become increasingly popular over the past few years. However, in the context of low-income areas of United States, these wearable devices are still pricey and thus constitute a critical bottleneck in their adoption. In this talk, I will present our past and ongoing works on repurposing electronic wastes, particularly everyday earphones into health trackers - from heart rate monitoring, heart sound recovery, all the way down to pulse wave velocity estimation in home settings. I will also discuss the potential of these technologies for filling the gap of remote health care. I believe this research creates a holistic approach toward recycling and repurposing electronic waste while fostering a sustainable and equitable future. Biography:…

Past Webinar – Intelligent Mobile Systems for an Aging World, Justin Chan (September 23, 2025 @4pm ET)

https://www.youtube.com/watch?v=EUH-9jR48Fo Abstract: By 2050, older adults will make up about 22% of the global population, driving an urgent need for accessible and reliable health technologies. In this talk, I will present our work on intelligent mobile systems designed for older adults. The first enables low-cost health screening using everyday earphones and wireless earbuds. The second is an ambient sensing system that uses smart devices to detect emergent, life-threatening events such as cardiac arrest. The third leverages compact AI-enabled radios for cardiovascular monitoring, including blood pressure. Through these examples, I will show how computational and sensing techniques that generalize across hardware and operate in real-world environments can address pressing societal challenges.

Past Webinar – The Impact of Light Exposure on Sleep: A Pilot Study, Erik Page (Blue Iris Labs)

https://www.youtube.com/watch?v=BcBlsqpNYeg Abstract: Light exposure is the primary regulator of human circadian rhythms, influencing many aspects of our physiology and behavior, including sleep, alertness, and mood, as well as many neuroendocrine and cognitive functions. While we have evolved experiencing “bright days and dark nights,” most of us now experience significantly darker days and brighter nights than our pre-modern ancestors, likely resulting in widespread circadian disruption. And as we age, the relationship between light exposure, circadian rhythms, and sleep can be further compromised both through normal aging (e.g., less light reaching the retina due to clouding of the lens) and age-related risk factors, such as Alzheimer’s Disease (AD), which is known to damage the brain’s master clock. This webinar will review the current science related to light exposure, circadian rhythms, and sleep, looking at aging and AD…

Past Webinar – Comprehending Human Behaviors using Wireless Sensing on Everyday Wearables, Cheng Zhang

https://youtu.be/glSoPDySruI?si=3vaFP2iwT9eKCDN2 Abstract: Despite the rapid advancement of AI, computers' ability to comprehend human behaviors remains limited. For instance, commodity computing devices still face challenges in understanding even basic human daily activities such as eating and drinking. The primary obstacle lies in the absence of suitable sensing technologies capable of capturing and interpreting high-quality behavioral data in everyday settings. In this presentation, I will share my research on the development of everyday wearables that are minimally-obtrusive, privacy-aware, and low-power, yet capable of capturing and comprehending various body movements and poses that humans employ in their everyday activities. First, I will show how these sensing technologies can empower various everyday wearable form factors, including wristbands, necklaces, earphones, headphones, and glasses, to track essential body postures, such as facial expressions, gaze, finger poses, limb poses, as well as…

Past Webinar – Sustainable Ear-Worn Systems for HCI and BCI: Design, Development, and Deployment, VP Nguyen

https://www.youtube.com/watch?v=kUKKp4Fazno&t=3s&pp=ygUNYTIgY29sbGVjdGl2ZQ%3D%3D Abstract: This talk introduces curiosity-driven research that explores science and technology to build the next generation of ear-worn computer systems that are robust, sustainable, cost-effective, low-burden, and socially acceptable, thereby unlocking new applications in human-computer interaction and brain-computer interface. Yet, the development of these systems brings significant challenges, demanding a rethinking of hardware and software frameworks, advanced ML algorithms, and significant interdisciplinary efforts. I will present our approaches to fill the gaps and build practical ear-worn computers, highlighted by motivating applications our lab has worked on: interactive computing and disease monitoring and intervention. Additionally, I will share insights gained from deploying these systems in various real-world settings and discuss future research directions.  Biography: VP Nguyen, PhD, Assistant Professor, Department of Computer Science at the Manning College of Information & Computer Science at UMass Amherst…

MassAITC Webinar – Opportunities and Challenges in Automatic Detection of Momentary Stress via Wearables, Santosh Kumar

https://youtu.be/wKgXSOgZSdU?si=PjYmoeQYrISdVqdz Talk Abstract:  Stress, a double-edged sword, has been long recognized for its potential to fuel productivity, enhance performance, and provide life-saving bursts of energy in times of imminent danger. Excessive and repetitive stress, however, can harm our physiological, psychological, behavioral, and social well-being. Due to its wide prevalence and impact in our lives, stress detection is increasingly being introduced in smartwatches, rings, and other wearables to help us become aware of and mitigate excessive stress. But unlike activity tracking, stress detection is yet to be adopted widely. What makes real-life stress detection so challenging? What progress has been made thus far and what else needs to be done to make stress detection truly useful? About the Speaker:  Santosh Kumar is the Lillian & Morrie Moss Chair of Excellence Professor in Computer Science at the…
