From Invisible to Actionable: Augmented Reality Interactions with Indoor CO2

Indoor carbon dioxide (CO\textsubscript{2}) can rapidly accumulate to form invisible pollution \textit{hotspots}, posing significant health risks due to its odorless and colorless nature. Despite growing interest in wearable or stationary sensors for pollutant detection, effectively visualizing CO\textsubscript{2} lev…

MorsEar: Toward Generalizable Low-Resource Covert Messaging via Earable based Inertial Sensing

Silent, eyes-free text entry remains challenging when speech and touch are impractical. Prior wearable systems required custom sensors or limited users to a small vocabulary. We present MorsEar, an IMU-only earable framework that maps near-ear micro-gestures such as taps for dot/dash; slide/pull/circle for space/dele…

DriveR: Towards Generating a Dynamic Road Safety Map with Causal Contexts

Road safety remains a critical global concern, with millions of crashes reported annually. Understanding the safety of individual road junctions is vital, especially in areas prone to road rage and reckless driving. However, current navigation systems lack detailed safety information, increasing risk for drivers and p…

ExpresSense: Exploring a Standalone Smartphone to Sense Engagement of Users from Facial Expressions Using Acoustic Sensing

Facial expressions have been considered a metric reflecting a person’s engagement with a task. While the evolution of expression detection methods is consequential, the foundation remains mostly on image processing techniques that suffer from occlusion, ambient light, and privacy concerns. In this paper, we propose Ex…

Bifurcating Cognitive Attention from Visual Concentration: Utilizing Cooperative Audiovisual Sensing for Demarcating Inattentive Online Meeting Participants

The profuse popularity of video conferencing has led to a simultaneous rise in the opportunity for the participants to multitask. Productive multitasking, such as taking notes, browsing for relevant information, etc., can help promote the cognitive attentiveness of participants. However, existing approaches of tagging…
