Wireless Sensing (WS) provides a low-cost means of monitoring humans and objects for the
next generation of IoT. However, the deployment of WS for various applications is limited by; …

We present ENGAGE, the first battery-free, personal mobile gaming device powered by
energy harvested from the gamer actions and sunlight. Our design implements a power …

Recognition of human behavior plays an important role in context-aware applications.
However, it is still a challenge for end-users to build personalized applications that …

Providing electrical power is essential for nearly all interactive technologies, yet it often
remains an afterthought. Some designs handwave power altogether as an “exercise for …

We propose a new technical approach to implement untethered VR haptic devices that
contain no battery, yet can render on-demand haptic feedback. The key is that via our …

Edges are one of the most ubiquitous geometric features of physical objects. They provide
accurate haptic feedback and easy-to-track features for camera systems, making them an …

In smart homes, access-control policies increasingly depend on contexts, such as who is
taking an action, whether there is an emergency, or whether an adult is nearby. The vast …

Ground surfaces are often carefully designed and engineered with various textures to fit the
functionalities of human environments and thus could contain rich context information for …

Should you decide to launch a nano-satellite today in Low-Earth Orbit (LEO), the cost of
renting ground station communication infrastructure is likely to significantly exceed your …

Light bulbs have been recently explored to design Light Fidelity (LiFi) communication to
battery-free tags, thus complementing Radiofrequency (RF) backscatter in the uplink. In this …
