We present Skinput, a technology that appropriates the human body for acoustic
transmission, allowing the skin to be used as an input surface. In particular, we resolve the …

Modern smartphones contain sophisticated sensors to monitor three-dimensional movement
of the device. These sensors permit devices to recognize motion gestures-deliberate …

We present TapSense, an enhancement to touch interaction that allows conventional
surfaces to identify the type of object being used for input. This is achieved by segmenting …

Current touch input technologies are best suited for small and flat applications, such as
smartphones, tablets and kiosks. In general, they are too expensive to scale to large …

In this paper, we present a novel acoustic touch sensing technique called Touch & Activate.
It recognizes a rich context of touches including grasp on existing objects by attaching only a …

Human environments are typified by walls, homes, offices, schools, museums, hospitals and
pretty much every indoor context one can imagine has walls. In many cases, they make up a …

While tremendous advances in visual and auditory realism have been made for virtual and
augmented reality (VR/AR), introducing a plausible sense of physicality into the virtual world …

We present Z-Ring, a wearable ring that enables gesture input, object detection, user
identification, and interaction with passive user interface (UI) elements using a single …

We explore techniques for hand-held devices that leverage the multimodal combination of
touch and motion. Hybrid touch+ motion gestures exhibit interaction properties that combine …

We introduce Acoustruments: low-cost, passive, and power-less mechanisms, made from
plastic, that can bring rich, tangible functionality to handheld devices. Through a structured …
