Asymmetric Performance in the Cocktail Party Effect: Implications for the Design of Spatial Audio Displays
An experiment was conducted to determine the extent to which hemispheric specialization is manifested in the performance of tasks in which listeners are required to attend to one of several simultaneously spoken speech communications. Speech intelligibility...
Auditory Localization under Sustained [+G.Sub.Z] Acceleration
The ability to localize a virtual sound source in the horizontal plane was evaluated under varying levels of sustained ([+G.sub.z]) acceleration. Participants were required to judge the locations of spatialized noise bursts in the horizontal plane...
Effect of Computer Keyboard Slope and Height on Wrist Extension Angle
The goal of this study was to determine the systematic effect that varying the slope angle of a computer keyboard along with varying keyboard height (relative to elbow height) have on wrist extension angle while typing. Thirty participants typed on...
Haptic Force-Feedback Devices for the Office Computer: Performance and Musculoskeletal Loading Issues
Pointing devices, essential input tools for the graphical user interface (GUI) of desktop computers, require precise motor control and dexterity to use. Haptic force-feedback devices provide the human operator with tactile cues, adding the sense of...
Incidental Memory and Navigation in Panoramic Virtual Reality for Electronic Commerce
Recently much effort has been dedicated to designing and implementing World Wide Web sites for virtual shopping and e-commerce. Despite this effort, relatively little empirical work has been done to determine the effectiveness with which different...
Information Order and Outcome Framing: An Assessment of Judgment Bias in a Naturalistic Decision-Making Context
Findings that decision makers can come to different conclusions depending on the order in which they receive information have been termed the "information order bias." When trained, experienced individuals exhibit similar behaviors; however, it has...
Management by Consent in Human-Machine Systems: When and Why It Breaks Down
This study examined the effects of conflict type, time pressure, and display design on operators' ability to make informed decisions about proposed machine goals and actions in a management-by-consent context. A group of 30 B757 pilots were asked to...
Menu Design with Visual Momentum for Compact Smart Products
Users of compact smart products with small screens often have trouble learning the menu structure. If they cannot master the menu structure, users are not able to fully utilize the products. It is argued in this paper that using visual momentum in...
Multichannel Auditory Search: Toward Understanding Control Processes in Polychotic Auditory Listening
Two experiments are presented that serve as a framework for exploring auditory information processing. The framework is referred to as polychotic listening or auditory search, and it requires a listener to scan multiple simultaneous auditory streams...
Pathway HUDs: Are They Viable?
We describe two experiments that examine 3D pathway displays in a head-up location for aircraft landing and taxi. We address both guidance performance and pilot strategies in dividing, focusing, and allocating attention between flight path information...
The Influence of Stimulants, Sedatives, and Fatigue on Tunnel Vision: Risk Factors for Driving and Piloting
A computerized task was used in two studies to examine the influence of stimulants, sedatives, and fatigue on single-target and divided-attention responses in different parts of the visual field. The drug effects were evaluated over time with repeated...
Use of Warnings in an Attentionally Demanding Detection Task
The study assessed the use of binary warnings in a detection task with high attentional demands. Participants in the experiment had to decide whether to continue or halt production based on a briefly displayed number that indicated a temperature level....
Visual Search for Traffic Signs: The Effects of Clutter, Luminance, and Aging
Latency and eye movement measures were used to examine the effects of aging, clutter, and luminance on visual search for traffic signs embedded in digitized images of driving scenes. Initially 14 older and 14 younger observers classified daytime and...
