We present StarLight, an infrastructure-based sensing system that reuses light emitted from
ceiling LED panels to reconstruct fine-grained user skeleton postures continuously in real …

Mobile devices are shrinking their form factors for portability, but user-mobile interaction is
becoming increasingly challenging. In this paper, we propose a novel system called Okuli to …

We present Pyro, a micro thumb-tip gesture recognition technique based on thermal infrared
signals radiating from the fingers. Pyro uses a compact, low-power passive sensor, making it …

Physical keyboards are common peripherals for personal computers and are efficient
standard text entry devices. Recent research has investigated how physical keyboards can …

Recent research advance has significantly improved the visual real-ism of immersive 3D
video communication. In this work we present a method to further enhance this immersive …

We evaluate and demonstrate finger, hand, and posture identification as keyboard shortcuts.
By detecting the hand and finger used to press a key, and open or closed hand postures, a …

A method of reducing the perceived latency of touch input by employing a model to predict
touch events before the finger reaches the touch surface is proposed. A corpus of 3D finger …

We present a novel natural user interface framework, called Meta-Gesture, for selecting and
manipulating rotatable virtual reality (VR) objects in egocentric viewpoint. Meta-Gesture …

Advanced AR/VR headsets often have a dedicated depth sensor or multiple cameras, high
processing power, and a high-capacity battery to track hands or controllers. However, these …

We present a lightweight technique with which creators can prototype force-sensitive objects
by attaching a pair of piezoelectric elements: one a vibration speaker and one a contact …
