Pilot Performance And Eye Movement Activity With Varying Levels Of Display Integration In A Synthetic Vision Cockpit, Julie Michele Stark

Psychology Theses & Dissertations

The primary goal of the present study was to investigate the effects of display integration in a simulated commercial aircraft cockpit equipped with a synthetic vision display. Combinations of display integration level (low/high), display view (synthetic vision view/traditional display), and workload (low/high) were presented to each participant. Sixteen commercial pilots flew multiple approaches under IMC conditions in a moderate fidelity fixed-base part-task simulator. Pilot performance data, visual activity, mental workload, and self-report situation awareness were measured.

Congruent with the Proximity Compatibility Principle, the more integrated display facilitated superior performance on integrative tasks (lateral and vertical path maintenance), whereas a less …

Analyzing The Effects Of Display Characteristics And Cognitive Variables On Performance Using Keystroke And Eye Movement Data, Orhan E. Beckman

Psychology Theses & Dissertations

Information about how operators use their eyes while interacting with visual displays is often an overlooked aspect of human-computer interaction. Such information is fundamental to assessing the quality of software interfaces and understanding the cognitive processes that underlie operator behavior. Other research evaluating information displays evolved from using reaction time and subjective data as dependent variables to using oculometric measures. In the current research conventional performance measures are coupled with oculometric measures to evaluate the influence display characteristics and cognitive variables have on performance.

Twelve subjects used a software program to complete a series of specified tasks. Subjects were asked …

Oculometric Indices Of Simulator And Aircraft Motion, James Raymond Comstock Jr.

Psychology Theses & Dissertations

In a series of three experiments on the effects on eye-scan behavior of both simulator and aircraft motion, the sensitivity of an oculometric measure to motion effects was demonstrated. "Fixation Time", defined as the time the eyes spend at a particular location before moving on (saccade) to another fixation point, was found to be sensitive to motion effects in each of the experiments conducted. The first experiment studied differences between simulator motion and no-motion conditions during a series of simulated Instrument Landing System (ILS) approaches. The mean fixation time for the no-motion condition was found to be significantly longer than …

An Error-Dependent Model Of Instrument-Scanning Behavior In Commercial Airline Pilots, Dennis H. Jones

Psychology Theses & Dissertations

Since the work of Fitts and his colleagues, researchers have been using eye-movement data to evaluate various aspects of pilot instrument scanning behavior. Although Senders' work indicated that link values and transitional probabilities could be accurately predicted using a random sampling process, several investigators have recently suggested that pilot scanning behavior was deterministic. However, there has been no clear empirical evidence to support a deterministic hypothesis. The present research presents a new flexible model of pilot instrument scanning behavior which assumes that the pilot uses a set of deterministic scanning patterns on (1) the pilot's perception of error in the …
