Research Overview

I adopt a human-centered perspective design sustainable sensing and interaction systems to bridge the physical and digital world. I develop power and information interconnection techniques to offload energy and computing intensive tasks from resource-constrained things to resource-abundant computers. My previous work falls into three categories, each corresponds to one aspect of the Thing-computer interconnection computing paradigm:

  1. Sensing Tags. I augment everyday objects with ultra-low-power, easy-to-use, and non-intrusive wireless sensing tags, which have low expense, deployment cost, and maintenance cost.
  2. Finger Wearables. I develop multi-purpose, power-efficient, and privacy-protective finger wearables, which can provide a rich, spontaneous, and consistent interaction experience.
  3. Interconnection Techniques. I establish both power and information links among devices to redistribute the power, computational, and interactive resources, especially between today’s powerful on-body devices and resource-limited off-body devices.

Sensing Tags

I invent passive sensors that can be deployed in a DIY manner to detect object status and human behaviors.

Finger Wearables

I design modularized smart rings and use a thermal imaging smart ring to detect gesture and tag inputs.

Interconnection

I develop power transfer and cross-device interaction techniques for interactive IoT devices.
