This study was conducted as part of the Active User Interface Group in the Intelligent Distributed Information Systems Lab at the Booth Research Center in the Deparment of Computer Science and Engineering in the School of Engineering at the University of Connecticut. I consulted with group members Hien Nguyen, Qunhua Zhao on a weekly basis and was advised by Professor Eugene Santos Jr.
As part of the Active User Interfaces group, I conducted a quantitative usability evaluation of the adaptive user modeling system in Kavanah, a medical information retrieval system. I used a measure I concocted based on task time, performance, subjective effectiveness and the NASA task load index. These measures combined to form subjective and objective measures of usability measured as input versus output. I found no effect. However, based on my observations I made several recommendations for improvements.
