Our hands serve as a fundamental means of interaction with the world around us. Therefore,
understanding hand poses and interaction contexts is critical for human-computer …

Wearable technologies provide a non-invasive way to monitor user's activity, identity, and
health in real-time, which have attracted tremendous interests from both academia and …

Current Virtual Reality systems typically use cameras to capture user input from controllers
or free-hand mid-air interaction. In this paper, we argue that this is a key impediment to …

Gestures performed accompanying the voice are essential for voice interaction to convey
complementary semantics for interaction purposes such as wake-up state and input …

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

TriPad enables opportunistic touch interaction in Augmented Reality using hand tracking
only. Users declare the surface they want to appropriate with a simple hand tap gesture …

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 …

Despite advancements in egocentric hand tracking using head-mounted cameras, contact
detection with real-world objects remains challenging, particularly for the quick motions often …

Ubiquitous touch sensing surfaces are largely influenced by touchscreens' look and feel and
fail to express the physical richness of existing surrounding materials. We introduce …

While passive surfaces offer numerous benefits for interaction in mixed reality, reliably
detecting touch input solely from head-mounted cameras has been a long-standing …
