SoundBubble: Finger-Bound Virtual Microphone using Headset/Glasses Beamforming

Hands are the chief appendage with which we manipulate the world around us, creating sounds as they go. As such, they are a rich source of information that computers can leverage for input and context sensing. Indeed, many prior works in HCI have explored this idea by instrumenting users' hands with a microphone, ofte…

PatternTrack: Multi-Device Tracking Using Infrared, Structured-Light Projections from Built-in LiDAR

As augmented reality devices (e.g., smartphones and headsets) proliferate in the market, multi-user AR scenarios are set to become more common. Co-located users will want to share coherent and synchronized AR experiences, but this is surprisingly cumbersome with current methods. In response, we developed PatternTrack,…

SoundScroll: Robust Finger Slide Detection Using Friction Sound and Wrist-Worn Microphones

Smartwatches have firmly established themselves as a popular wearable form factor. The potential expansion of their interaction space to nearby surfaces offers a promising avenue for enhancing input accuracy and usability beyond the confines of a small screen. However, a key challenge is in detecting continuous contac…

Power-over-Skin: Full-Body Wearables Powered By Intra-Body RF Energy

Powerful computing devices are now small enough to be easily worn on the body. However, batteries pose a major design and user experience obstacle, adding weight and volume, and generally requiring periodic device removal and recharging. In response, we developed Power-over-Skin, an approach using the human body itsel…

Pantœnna: Mouth Pose Estimation for AR/VR Headsets Using Low-Profile Antenna and Impedance Characteristic Sensing

Methods for faithfully capturing a user's holistic pose have immediate uses in AR/VR, ranging from multimodal input to expressive avatars. Although body-tracking has received the most attention, the mouth is also of particular importance, given that it is the channel for both speech and facial expression. In this work…

EtherPose: Continuous Hand Pose Tracking with Wrist-Worn Antenna Impedance Characteristic Sensing

EtherPose is a continuous hand pose tracking system employing two wrist-worn antennas, from which we measure the real-time dielectric loading resulting from different hand geometries (i.e., poses). Unlike worn camera-based methods, our RF approach is more robust to occlusion from clothing and avoids capturing potentia…

TriboTouch: Micro-Patterned Surfaces for Low Latency Touchscreens

Touchscreen tracking latency, often 80ms or more, creates a rubber-banding effect in everyday direct manipulation tasks such as dragging, scrolling, and drawing. This has been shown to decrease system preference, user performance, and overall realism of these interfaces. In this research, we demonstrate how the additi…
