Abstract

Radio-frequency identification (RFID) is a powerful automatic remote 
identification technology that has wide applications. To effectively 
deploy an RFID system to a certain application, engineers have to 
carefully select and seamlessly integrate RFID components such as tags and 
antennae. To facilitate the RFID deployment, RFID Benchmarking is required 
to identify the strength and weakness of different RFID technologies in 
various environments. However, the data acquired by RFID benchmarking are 
usually complex time-varying multi-dimensional 3D volumetric data, which 
poses a great challenge for the engineers to analyze using existing 
numerical approaches. In this thesis, we introduce a new visualization 
system to help RFID end-users visually analyze the special RFID benchmark 
data in an intuitive manner by employing their perceptual and cognitive 
capabilities, intuition, and background knowledge. The system is 
comprehensive and consists of four major visualization components: 
parallel coordinate plots, a history viewer, orientation plots, and a 3D 
spatial viewer. With the system, users can figure out the optimal spatial 
configuration of RFID components by visual optimization efficiently, 
compare the performance of different RFID technologies intuitively, and 
detect the flaws and problems of RFID devices effectively. The usefulness 
and usability of the system have been demonstrated in the case studies and 
user evaluation.
