FlowRing: Integrated Microgesture and Surface Interaction Ring for Versatile XR Input

As Extended Reality (XR) advances, a device has the potential to be used across contexts from immersive productivity at a desk to on-the-go, public scenarios. Existing input solutions lack the versatility to provide both high-throughput, mouse-grade input and subtle, ergonomic interaction. We introduce FlowRing, a nov…

ECG Necklace: Low-power Wireless Necklace for Continuous ECG monitoring

Continuous, everyday ECG monitoring is essential for detecting transient heart conditions and enabling early intervention in cardiovascular diseases. However, current technologies, such as ECG Holter monitors and smartwatches, face challenges in balancing continuous monitoring with long-term wearability due to trade-o…

NightLight: Passively Mapping Nighttime Sidewalk Light Data for Improved Pedestrian Routing

Nighttime sidewalk illumination has a significant and unequal influence on where and whether pedestrians walk at night. Despite the importance of pedestrian lighting, there is currently no approach for measuring and communicating how humans experience nighttime sidewalk light levels at scale. We introduce NightLight,…

"A Tool for Freedom": Co-Designing Mobility Aid Improvements Using Personal Fabrication and Physical Interface Modules with Primarily Young Adults

Mobility aids (e.g., canes, crutches, and wheelchairs) are crucial for people with mobility disabilities; however, pervasive dissatisfaction with these aids keeps usage rates low. Through semi-structured interviews with 17 mobility aid users, mostly under the age of 30, we identified specific sources of dissatisfactio…

ProxiCycle : Passively Mapping Cyclist Safety Using Smart Handlebars for Near-Miss Detection

Active transportation is a valuable tool to prevent some of the most common causes of mortality worldwide, but is severely underutilized. The primary factors preventing cyclist adoption are safety concerns, specifically, the fear of collision from automobiles. One solution to address this concern is to direct cyclists…
