Madathil, Kapil Chalil, Koikkara, Reshmi, Dorlette-Paul, Melissa, Ranganayakulu, Sanjay, Greenstein, Joel S. and Gramopadhye, Anand K. (2012): An investigation of format modifications on the comprehension of information in consent form when presented on mobile devices. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 921-925.

“A major challenge associated with converting paper-based consent to electronic versions is to assure that the level of comprehension offered by the electronic consenting systems is not reduced. A randomized between-subject trial comparing patient comprehension with four different electronic consenting formats of the same consent information presented on an Apple iPad was conducted using a non-clinical sample of 32 participants. The formats were Text-Based, text-based with Text Being Read out, Video-Based and Video-Based with Subtitles. The participants were asked to read and complete a consent form in one of the formats. The participants were subsequently asked to complete a semantic comprehension quiz, the NASA Task Load Index and the computer system usability questionnaire (CSUQ). Upon completing the questionnaires, the participants took part in a retrospective think-aloud session to understand any difficulties they had using the consent forms. Statistically significant differences among the formats were found for task completion time, the mental demand and frustration sub-components of the NASA-TLX, and the comprehension quiz. Video with subtitles to convey consent information appears to be the best format among the formats tested for electronic consent presentation.”

Madathil, Kapil Chalil, Koikkara, Reshmi, Gramopadhye, Anand K. and Greenstein, Joel S. (2011): An Empirical Study of the Usability of Consenting Systems: iPad, Touchscreen and Paper-based Systems. In: Proceedings of the Human Factors and Ergonomics Society 55th Annual Meeting 2011. pp. 813-817.

“While much research has been conducted on the software system architecture needed for capturing and managing patient consents and research permissions in health care facilities, limited information is available on the usability of such capture systems. Typically, a general consenting process involves the patients indicating their choices and then signing/initialing to verify these preferences. This study proposes four new ways of capturing these consents/research permissions using Apple iPad and touchscreen-based systems, investigating their feasibility and usability by comparing them to the conventional paper-based consenting process. Fifteen participants completed the consenting process using five capture systems: iPad-based system with pagination and scrolling interfaces, touchscreen-based system with pagination and scrolling interfaces and the paper-based system. After each consenting condition, the participants completed the NASA Task Load Index (NASA-TLX), the computer system usability questionnaire (CSUQ), and a post-test subjective questionnaire ranking the consenting systems based on preference. Statistically significant differences among the consent capture systems were found for all dependent variables except for task completion time. The iPad and touchscreen systems with pagination interfaces were preferred.”

Vembar, Deepak, Duchowski, Andrew T., Gramopadhye, Anand K. and Washburn, Carl (2009): Improving simulated borescope inspection with constrained camera motion and haptic feedback. In: Proceedings of the 2009 Conference on Graphics Interface 2009. pp. 141-148.

“Results are presented from empirical evaluation of a borescope simulator developed for non-destructive inspection training. Two experiments were conducted, manipulating camera rotation constraint and provision of haptic feedback. Performance of experienced borescope inspectors is measured in terms of speed and accuracy, with accuracy clearly shown to improve by placing constraints on the simulator's camera tip rotation and by providing haptic response. This is important as damage avoidance of a real borescope is a critical criterion of borescope inspection training. These are likely to be the first such experiments to have been conducted with aircraft engine inspectors evaluating the potential of haptics in borescope simulation.”

Sadasivan, Sajay, Greenstein, Joel S., Gramopadhye, Anand K. and Duchowski, Andrew T. (2005): Use of eye movements as feedforward training for a synthetic aircraft inspection task. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 141-149.

“Aircraft inspection is a vital element in assuring safety and reliability of the air transportation system. The human inspector performing visual inspection of an aircraft is the backbone of this process and training is an effective strategy for improving their inspection performance. Previous studies have shown offline feedback training to be effective in improving subsequent visual inspection performance. Because experienced inspectors are known to adopt a better inspection strategy than novices, providing visualization of experts' cognitive processes a priori can accelerate novices' adoption of the experts' strategy. Using eye tracking equipment, we record the point of regard of an expert inspector performing an inspection task in a virtual reality simulator. Analysis of their eye movements leads to a visualization of their scanpaths and allows us to display the inspector's visual search (hence cognitive) strategy. We show how providing this type of scanpath-based feedforward training of novices leads to improved accuracy performance in the simulator coupled with an observed speed-accuracy tradeoff. We contend that the tradeoff results from trained novices adopting a slower paced strategy through increased fixation durations, suggesting trained novices learn a more deliberate target search/discrimination strategy that requires more time to execute.”

“Previous task analysis of aircraft inspection/maintenance operations and FAA reports have reported the importance teamwork plays in completing aircraft inspection/maintenance tasks. Hence, it is necessary that we identify team training strategies that will improve team skills, thereby improving team performance within the aircraft inspection/maintenance environment. This paper reviews that state-of-the-art literature on team training. Drawing from the task analysis of aircraft inspection and maintenance operations, site visits to repair facilities and a detailed review of the various team models, a framework developed as a first step in understanding teamwork in aircraft inspection and maintenance operations is reported. The paper also reports the results of a study conducted to evaluate the effectiveness of team training in the aircraft maintenance environment.”

“The combined effects of automation and global competition have changed the manufacturing environment considerably. The change is from a traditional product or process oriented manufacturing to a fully automated or semi-automated manufacturing environment, producing limited quantities of a large range of products. Inexpensive and unlimited computing power has been the single cause for these changes. What impact have these changes had on human factors/ergonomics professionals? Does a problem really exist and is its existence recognized in affected areas by other people, those not involved with human factors? Have human factors professionals taken proactive approaches to these changes? What are the new techniques available to the human factors professionals in this application area? This panel will address some of the issues and concerns in this area.”

“Visual lobe continues to be an important determinant of extended search performance. This study looks at the effect of various methods of training on visual lobe size. Furthermore, it relates changes in visual lobe size to improvements in visual search performance. Subjects were trained using three different methods. In method 1 subjects were trained on a visual lobe improvement task using the actual fault. In method 2 subjects were trained on an irrelevant target using the visual lobe measurement task and in method 3 subjects were provided practice on the extended visual search task. Greatest improvements in lobe size and search performance were observed for method 1.”

“Research on civil aircraft inspection and maintenance has shown the potential for employing human factor interventions in improving performance. A series of training experiments was developed to understand the effects of different training interventions in the visual inspection domain. This paper reports on preliminary results obtained in applying a combined active and progressive part training scheme in improving the decision making performance for a visual inspection task. The task was a computer simulated airframe visual inspection task.”
