Contextra: Detecting Object Grasps With Low-Power Cameras and Sensor Fusion On the Wrist

Knowing when a user picks up an object plays a vital role in many context-aware applications. For example, tracking water consumption, counting calories consumed, or reminding you to bring your keys are all context-centered scenarios involving picking up objects. In this project, we propose Contextra, a wrist-worn sys…

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…

picoRing: battery-free rings for subtle thumb-to-index input

Smart rings for subtle, reliable finger input offer an attractive path for ubiquitous interaction with wearable computing platforms. However, compared to ordinary rings worn for cultural or fashion reasons, smart rings are much bulkier and less comfortable, largely due to the space required for a battery, which also…

ElectroRing: Subtle Pinch and Touch Detection with a Ring

We present ElectroRing, a wearable ring-based input device that reliably detects both onset and release of a subtle finger pinch, and more generally, contact of the fingertip with the user's skin. ElectroRing addresses a common problem in ubiquitous touch interfaces, where subtle touch gestures with little movement or…

True Touch: Precise Touch Detection for On-Skin AR/VR Interfaces

Contemporary AR/VR systems use in-air gestures or handheld controllers for interactivity. This overlooks the skin as a convenient surface for tactile, touch-driven interactions, which are generally more accurate and comfortable than free space interactions. We developed RFTouch, an electrical method that enables very…
