This study examined the effect of haptic feedback and visual distraction on pointing task performance in a 3D virtual environment. Results indicate a strong positive effect of haptic feedback on performance in terms of task time and root mean square error of motion. Level of similarity between distractor objects and the target object significantly reduced performance, and subjective ratings indicated a sense of increased task difficulty as similarity increased. Participants produced the best performance in trials where distractor objects had a different color but the same shape as the target object and constant haptic assistive feedback was provided. Overall, this study provides insight toward the effect of object features and similarity and the effect of haptic feedback on pointing task performance.}, number={2}, journal={INTERNATIONAL JOURNAL OF HUMAN-COMPUTER INTERACTION}, author={Corbett, Brendan and Nam, Chang S. and Yamaguchi, Takehiko}, year={2016}, pages={89–102} }

The current research assessed driver performance and attention allocation in a simulated freeway driving task when exposed to six-panel logo signs, nine-panel logo signs, mileage guide signs, and roadway work zones both with and without an in-car navigation device. The objective was to identify the impact of signage types on driver behavior under realistic driving conditions. Results revealed glance durations and fixation frequencies to guide signs to be significantly lower than with six-panel and nine-panel logo signs, but no differences were found between six-panel and nine-panel logo signs. There were also statistical differences among the independent variables for speed deviation and lane deviation, but magnitudes were not large enough to be considered practically significant in terms of driving safety. Overall, there were minor differences in sign processing time between logo signs and mileage guide signs, but such differences did not translate to degradations in vehicle control.}, journal={APPLIED ERGONOMICS}, author={Kaber, David and Pankok, Carl, Jr. and Corbett, Brendan and Ma, Wenqi and Hummer, Joseph and Rasdorf, William}, year={2015}, month={Mar}, pages={99–106} }
 @article{bahn_corbett_nam_2014, title={Scenario-Based Observation Approach for Eliciting User Requirements for Haptic User Interfaces}, volume={30}, ISSN={["1532-7590"]}, DOI={10.1080/10447318.2014.941271}, abstractNote={As tactual information processing of visually impaired users has not been investigated sufficiently and there are few guidelines on the development of haptic user interfaces, development of haptic assistive system can pose many challenges. Despite the breadth and variety of tools available for elicitation of user requirements, no single tool adequately provides the needed information to develop such a specialized system for a unique user population where the understanding of user behaviors is limited. This article explores the state-of-art of requirements engineering, discusses the challenges in developing a haptic assistive system, and proposes a methodology of combining a controlled observation in a naturalistic setting with scenario-based design for effective and efficient user requirements elicitation. A case study of developing a haptically enhanced, collaborative learning-by-feeling science education system for visually impaired students was conducted to show validity and effectiveness of the proposed methodology. The case study showed that the methodology has a variety of benefits including the reduced uncertainty and a better fit to the natural behaviors of the user population.}, number={11}, journal={INTERNATIONAL JOURNAL OF HUMAN-COMPUTER INTERACTION}, author={Bahn, Sangwoo and Corbett, Brendan and Nam, Chang S.}, year={2014}, month={Nov}, pages={842–854} }
