Orienting Of Visual-Spatial Attention With Augmented Reality: Effects Of Spatial And Non-Spatial Multi-Modal Cues, Christian Jerome Jan 2006

Orienting Of Visual-Spatial Attention With Augmented Reality: Effects Of Spatial And Non-Spatial Multi-Modal Cues, Christian Jerome

Electronic Theses and Dissertations

Advances in simulation technology have brought about many improvements to the way we train tasks, as well as how we perform tasks in the operational field. Augmented reality (AR) is an example of how to enhance the user's experience in the real world with computer generated information and graphics. Visual search tasks are known to be capacity demanding and therefore may be improved by training in an AR environment. During the experimental task, participants searched for enemies (while cued from visual, auditory, tactile, combinations of two, or all three modality cues) and tried to shoot them while avoiding shooting ...


Classroom Observation Of Children With Adhd And Their Peers: A Meta-Analytic Review, Michael Kofler Jan 2006

Classroom Observation Of Children With Adhd And Their Peers: A Meta-Analytic Review, Michael Kofler

Electronic Theses and Dissertations

Meta-analysis of 23 between-group direct observation studies of children with ADHD and typically developing peers indicates significant deficiencies in children with ADHD's ability to pay attention in classroom settings. Comparison with 59 single case design studies of children with ADHD suggests generalizability of between-group comparisons. Weighted regression analysis determined that several methodological differences – sample characteristics, diagnostic procedures, and observational coding schema – have significant effects on observed levels of attentive behavior in the classroom. Best case estimation indicates that after accounting for these factors, children with ADHD are on-task approximately 65% of the time compared to 85% for their classroom ...


Individual Preferences In The Use Of Automation, Jennifer Thropp Jan 2006

Individual Preferences In The Use Of Automation, Jennifer Thropp

Electronic Theses and Dissertations

As system automation increases and evolves, the intervention of the supervising operator becomes ever less frequent but ever more crucial. The adaptive automation approach is one in which control of tasks dynamically shifts between humans and machines, being an alternative to traditional static allocation in which task control is assigned during system design and subsequently remains unchanged during operations. It is proposed that adaptive allocation should adjust to the individual operators' characteristics in order to improve performance, avoid errors, and enhance safety. The roles of three individual difference variables relevant to adaptive automation are described: attentional control, desirability of control ...
