Ecological Interface Design In Variable Workload Multitasking, James Rubinstein
Ecological Interface Design In Variable Workload Multitasking, James Rubinstein
All Theses
This study was undertaken to examine the question of how well Ecological Interface Design (EID) would support operators of a multitasking work domains. Previous research has shown that EID can support better operator performance while controlling a simulated process. Recently, there has been some interest in applying EID to automobiles, planes, and other multitasking domains. This research aimed to answer a more basic question: whether or not people could detect errors using EID while trying to do well on a visual psychomotor task.
The experiment used two tasks. The first task involved monitoring errors in a simulated process control plant, …
Perception And Displays For Teleoperated Robots, Linda Upham Ellis
Perception And Displays For Teleoperated Robots, Linda Upham Ellis
Electronic Theses and Dissertations
In remote or teleoperational tasks involving humans and robots, various aspects of the remote display system may greatly influence the individual's interactions with the teleoperated entity. This dissertation examined various configurations of display systems on several measures of operator performance, physiological states, and perceptions of the task. Display configurations included altering the camera placement (attached to the robot or placed overhead), screen orientation (horizontal or vertical), and screen size (small or large). Performance was measured in terms of specific task goals, accuracies, strategies, and completion times. Physiological state was assessed through physiological markers of arousal, specifically heart rate and skin …
