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 …

Mobile device authentication has been a highly active research topic for over 10 years, with
a vast range of methods proposed and analyzed. In related areas, such as secure channel …

We present CapBand, a battery-free hand gesture recognition wearable in the form of a
wristband. The key challenges in creating such a system are (1) to sense useful hand …

The goal of this work is to enable user authentication via finger inputs on ubiquitous surfaces
leveraging low-cost physical vibration. We propose VibWrite that extends finger-input …

This paper explores a new wearable system, called TYTH, that enables a novel form of
human computer interaction based on the relative location and interaction between the …

This work enables mobile user authentication via finger inputs on ubiquitous surfaces
leveraging low-cost physical vibration. The system we proposed extends finger-input …

Many users find current smartphone authentication methods (PINs, swipe patterns) to be
burdensome, leading them to weaken or disable the authentication. Although some phones …

In this work, we design a wearable-form hand gesture recognition system using capacitive
sensing technique. Our proposed system includes a 3D printed wristband, capacitive …

Mobile virtual reality (VR) headsets, such as Google Cardboard and Samsung GearVR, can
reuse a smartphone as near-eye display to create immersive experience. But such devices …
