Designing interfaces or applications that move beyond the bounds of a single device screen
enables new ways to engage with digital content. Research addressing the opportunities …

We present fingerIO, a novel fine-grained finger tracking solution for around-device
interaction. FingerIO does not require instrumenting the finger with sensors and works even …

We propose a novel mobile system, called EchoTag, that enables phones to tag and
remember indoor locations without requiring any additional sensors or pre-installed …

This paper explores the possibility of extending the input and interactions beyond the small
screen of the mobile device onto ad hoc adjacent surfaces, eg, a wooden tabletop with …

We introduce AirLink, a novel technique for sharing files between multiple devices. By
waving a hand from one device towards another, users can directly transfer files between …

Smartphone notifications provide application-specific information in real-time, but could
distract users from in-person social interactions when delivered at inopportune moments …

Enabling computing systems to understand user interactions with everyday surfaces and
objects can drive a wide range of applications. However, existing vibration-based sensors …

We present MAF, a novel acoustic sensing approach that leverages the commodity
hardware in bone conduction earphones for hand-to-face gesture interactions. Briefly, by …

The advent of smart devices has caused unprecedented security and privacy concerns to its
users. Although the fingerprint technology is a go-to biometric solution in high-impact …

In this paper, we present Acustico, a passive acoustic sensing approach that enables tap
detection and 2D tap localization on uninstrumented surfaces using a wrist-worn device. Our …
