Current Projects

2013-2015+

  • more TBA, stay tuned!
  • CLIS - Continuous Assessment of Cognitive Load in Information Seeking This project investigates cognitive load experienced by web information searchers. Cognitive load is affected not only by a person’s abilities and a task they perform, but also by a task stage and user interface. Eye movement and EEG data is collected from users engaged in information seeking in order to gain a new understanding of cognitive demands imposed by information search and to develop a measurement framework for non-intrusive assessment of cognitive load. Funded by IMLS Career award to Dr. Gwizdka: RE-04-11-0062-11.
  • LaSaL - Learning about Search as Learning: | Dr. Jacek Gwizdka
  • Consumer Health Information Evalation: Understanding Consumers: Quality Evaluation of Online Health Information Using a Mixed-Method Approach | Dr. Yan Zhang & Dr. Jacek Gwizdka (UT Austin Co-PIs) with Dr. Carla Teixeira Lopes (U Porto Co-PI)

Previous Projects

2012-2014

  • Multi-tasking - Or should we say “task switching?” Recent doctoral grad Ji Hyun Park has expanded our work on humans’ ability to multi-task (see Park, J. H., & Bias, R. G. [2012]). Understanding human multitasking behaviors through a lens of Goal-Systems Theory. Paper presented at the annual meeting of the Association for Library and Information Science Education, Dallas, January), and defended her dissertation, Flow in Multitasking: The Effects of Motivation, Artifact, and Task Factors, in July, 2014.

2012-2013

  • Which Usability Engineering Method When? Project PI: Dr. Randolph Bias. We are frustrated that there is so little empiricism driving the choice of which usability engineering method might yield the best bang for the dollar and hour invested.

2011-2012

  • Study to Better Understand Filler Text
  • WebMD Information Gathering User Study
  • User Study on Women's Voting Website
  • Arabic News Site Usability Study
  • User Study of Transcription with GLIFOS
  • Study of Reading Comprehension on eReaders
  • User Study of a Collaboration on a Touch Screen System
  • Study of Web Form Application on Mobile Devices
