An Evaluation of Warning Habits and Beliefs across the Adult Life Span
********** Beliefs about warnings and habits associated with reading them were assessed for 863 individuals of various ages. Information gathered for various common house-hold products included (a) how frequently people attend to warning information,...
Configural Display Design Techniques Considered at Multiple Levels of Evaluation
********** Two studies were conducted to examine issues in the design and evaluation of configural displays. Four design techniques (bar graphs/extenders, scale markers/scale grids, color coding/color layering/color separation, and annotation with...
Cursor Orientation and Computer Screen Positioning Movements
********** Implicit directional cues in arrowhead cursors could influence positioning of a cursor on the screen of the computer. Performance during cursor placement may benefit from compatibilities between cursor orientation and direction of movement....
Display Signaling in Augmented Reality: Effects of Cue Reliability and Image Realism on Attention Allocation and Trust Calibration
********** This experiment seeks to examine the relationships among three advanced technology features (presentation of target cuing, reliability of target cuing, and level of image reality and the attention and trust given to that information)....
Distance Perception of Vehicle Rear Lights in Fog
********** Perceptual difficulty is one of the main explanations given for the behavioral modifications and high accident rate associated with driving in fog. The present study investigates how fog and the characteristics of vehicle rear lights...
Effect of Flooring on Standing Comfort and Fatigue
********** This study investigated the influence of flooring on subjective discomfort and fatigue during standing and on potentially related objective measures. Participants stood for 4 h on each of 7 flooring conditions while performing computer...
Effect of Geometric Field of View on Stereoscopic Spatial Judgments
********** Within a stereoscopic display the field of view (FOV) was held constant at 13.86[degrees] while the geometric field of view (GFOV) was varied across four levels: [degrees] (parallel), 13.86[degrees] (veridical), 50[degrees] and 100[degrees]....
Effects of Navigation Speed on Motion Sickness Caused by an Immersive Virtual Environment
********** This study investigated the effects of navigation speed on the level of motion sickness during and after a 30-mm head-steered virtual environment. Root-mean-squares for 8 speeds in the fore-and-aft axis were 3, 4, 6, 8, 10, 24, 30, and...
Flying Personal Planes: Modeling the Airport Choices of General Aviation Pilots Using Stated Preference Methodology
********** This study employed stated preference (SP) models to determine why general aviation pilots choose to base and operate their aircraft at some airports and not others. Thirteen decision variables identified in pilot focus groups and in...
Human Performance Models and Rear-End Collision Avoidance Algorithms
********** Collision warning systems offer a promising approach to mitigate rear-end collisions, but substantial uncertainty exists regarding the joint performance of the driver and the collision warning algorithms. A simple deterministic model...
Monitoring Task Loading with Multivariate EEG Measures during Complex Forms of Human-Computer Interaction
********** Electroencephalographic (EEG) recordings were made while 16 participants performed versions of a personal-computer-based flight simulation task of low, moderate, or high difficulty. As task difficulty increased, frontal midline theta...
Role of Lateral Acceleration in Curve Driving: Driver Model and Experiments on a Real Vehicle and a Driving Simulator
********** Experimental studies show that automobile drivers adjust their speed in curves so that maximum vehicle lateral accelerations decrease at high speeds. This pattern of lateral accelerations is described by a new driver model, assuming drivers...
What Determines Whether Observers Recognize Targeted Behaviors in Modeling Displays?
********** Observational learning is based on a critical assumption that trainees can and do recognize critical modeled behaviors. This assumption has been virtually untested in applied settings. We studied the effects of work experience and instructions...
