I adopt a human-centered perspective to design pervasive interfaces and corresponding interaction techniques so that users can access the digtal world through everyday things. More specifically, I develop self-sustainable sensing tags and apply them on everyday things to form pervasive interfaces. However, such interfaces are limited in their functionalities due to size, cost, and power constrains. So on one side, I design interaction techniques for such resource-constrained interfaces; on the other side, I leverage the usually resource-abundant wearable devices to enrich and enchance such interfaces. Thus, my previous work falls into the following three categories:

1. Pervasive sensors and interfaces. To make everdaythings interactive and ‘smart’, I augment everyday objects with ultra-low-power, easy-to-use, and non-intrusive wireless sensing tags, which have low manufacture, deployment, and maintenance cost; I also develop novel powering methods to reduce users’ power maintenance efforts.
2. Resource-constrained interaction techniques (1st path). To support direct human-thing interaction, I design correlation-based and semantic-based interaction techniques that leverage the temporal domain and abstract mapping respectively to compensate for the weak sensing and computing capabilities of resource-constrained interfaces.
3. Computer-mediated pervasive interactive systems (2nd path). To enable more interaction possiblities with everyday things, I build interactive systems that leverage both the resource-abundant wearable computers and the resource-constrained pervasive interfaces. I am especially interested in combining finger wearables and AR headsets with IoT devices to enable human-centered pervasive interaction experience.
