Exploiting radio frequency signals is promising for locating and tracking objects. Prior works
focus on per-tag localization, in which each object is attached with one tag. In this paper, we …

This paper studies the problem of tag localization using RFID-augmented robots, which is
practically important for promising warehousing applications, eg, automatic item fetching …

We present the design, implementation, and evaluation of RFusion, a robotic system that
can search for and retrieve RFID-tagged items in line-of-sight, non-line-of-sight, and fully …

We present the design, implementation, and evaluation of X-AR, an augmented reality (AR)
system with non-line-of-sight perception. X-AR augments AR headsets with RF sensing to …

RFID technology has recently been exploited for not only identification but also for sensing
including trajectory tracking and gesture recognition. While contact-based (an RFID tag is …

We study a new problem, refined localization, in this paper. Refined localization calculates
the location of an object in high precision, given that the object is in a relatively small region …

Lip reading can help people with speech disorders to communicate with others and provide
them with a new channel to interact with the world. In this paper, we design and implement …

Gesture recognition based on radio frequency identification (RFID) has attracted much
research attention in recent years. Most existing RFID-based gesture recognition …

Currently, the logistic industry has introduced 3D reconstruction to monitor the package
placement in the warehouse. Previous 3D reconstruction solutions mainly utilize computer …

Individual activity recognition is crucial for Human-Computer Interaction (HCI) applications,
especially in multi-person scenarios. Current approaches, based on wearable sensors or …
