Applying Quality Control Charts to the Analysis of Single-Subject Data Sequences
(Human Factors: The Journal of the Human Factors and Ergonomics Society, 2000-12-01)
Techniques from the field of quality control can be used to classify the quality of individual samples of physical or cognitive performance. After stable baselines have been established for an individual, deviations in ...
Speed-Accuracy Tradeoffs in Spatial Orientation Information Processing
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1983-10-01)
A study was conducted to further evaluate the Manikin Task, a test of spatial orientation information processing. The objectives of the study were to determine the speed vs. accuracy tradeoff characteristics of the task ...
Development of the Criterion Task Set Performance Data Base
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1986-09-01)
The initial phase of a large-scale experimental study was conducted involving the training and testing of fifty human subjects on the Criterion Task Set (Version 1.0). Testing was performed under baseline conditions and ...
Identification of Stable Asymptotic Performance on Computer-Based Cognitive Tests
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1998-10-01)
Examining whether human cognitive performance is affected by environmental conditions requires stable performance measures prior to stressor exposure. This study evaluated the stability and reliability of six computer-based ...
Diagnosis of Low Back Injury Using Strength Measurement
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1984-10-01)
A study was conducted to investigate the feasibility of using strength measurement as a diagnostic technique for assessing low back injuries involving symptomatic lumbar spine disease. The approach was to evaluate differences ...
A Test of Fitts' Law in a Dual-Task Paradigm
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1993-10-01)
A simulated automobile driving environment was used to assess the validity of Fitts' Law under dual-task conditions. An aimed hand movement task was used as the Fitts task representative of reaching for controls on an ...
Toward the Construction of an Efficient Set of Robot Arm Operator Performance Metrics
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2004-09-01)
As part of a larger project to identify and validate relevant quantitative measures of robot arm operator proficiency, fifteen metrics of arm maneuvering and hand controller performance were defined and measured for 3-DOF ...
A Methodology for Investigating Heat Stress Selectivity Effects on Mental Performance
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1994-10-01)
This paper outlines a methodology that can be used to investigate the selectivity patterns of heat stress effects. The adopted view is that heat stress causes performance to deteriorate because it depletes attentional ...
Clinical Validation of the Ansi C63.19 Draft Standard for Measuring Compatibility between Digital Wireless Phones and Hearing Aids
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2000-07-01)
Acoustic interference can be generated in hearing aids by the pulsed transmission signal of a digital wireless phone. This interference, resembling a buzzing, clicking, or static sound, is annoying and can seriously degrade ...
Clinical Assessment of Electromagnetic Compatibility of Hearing Aids and Digital Wireless Phones
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1998-10-01)
Research studies have shown that digital wireless phones interact with some hearing aids, creating a buzzing noise that may reduce speech intelligibility. Interference signals for three phone technologies were generated ...
