This paper presents the NFC-WISP, which is a programmable, sensing and computationally enhanced platform designed to explore new RFID enabled sensing and user interface applications.

In this paper, we propose an unexplored type of wireless power transfer system based on electromagnetic cavity resonance.

This paper proposes using the electromagnetic resonant modes of a hollow metallic structure to provide wireless power to small receivers contained anywhere inside.

We propose a novel error tolerant optimization approach to generate a high-quality photometric compensated projection.

This work will show both theoretically and through experimentation that using high Q coils in the over-coupled regime supports extension of read range in near field RFID systems by 81% or more compared to the next best impedance matching strategies.

We show that with selective coding OAM states, off‐axis points and spatial variables encoded with OAM are reproducible.

We have developed a dynamic coarse integral holography approach using opto-mechanical scanning, coarse integral optics and a low space-bandwidth-product high-bandwidth spatial light modulator to display dynamic holograms with a large space-bandwidth-product at video rates, combined with an efficient rendering algorithm to reduce the information content.

In this work, we present a hybrid computer vision and RFID system that uses a novel reverse synthetic aperture technique to recover the relative motion paths of an RFID tags worn by people and correlate that to physical motion paths of individuals as measured with a 3D depth camera.

We describe techniques that allow inexpensive, ultra-thin, battery-free Radio Frequency Identification (RFID) tags to be turned into simple paper input devices.

In this work, we show how to achieve low-latency manipulation and movement sensing with off-the-shelf RFID tags and readers.
