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 ...
Application of a Predictive Coke Temperature Model to Heat Stress Experimentation
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1980-10-01)
An interactive procedure for evaluating and maintaining an individual's core temperature at a predetermined level was developed and tested. The procedure involved the use of previously developed models for predicting core ...
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 ...
A Human Factors Perspective on Helicopter Human External Loads
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1999-09-01)
Human external loads (HEL) refer to operations where humans are transported while suspended below a helicopter. HEL operations are often required to access remote work sites, to access power lines in need of maintenance ...
Evaluation of Static Work Capabilities in a Hot Environment
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1979-10-01)
The effects of heat stress on an individual's static work capabilities were investigated. Various indicators of strength and endurance were measured under differing heat stress levels. One measure which exhibited a significant ...
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 ...
The Use of Statistical Quality Control Charts to Evaluate Changes in Individual Performance
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1997-10-01)
An employee's readiness to perform (RTP) has become an important issue facing today's industries. Some industries have turned to cognitive performance testing to provide answers regarding their employee's abilities to work ...
Tactile Stimulation of the Human Head for Information Display
(Human Factors: The Journal of the Human Factors and Ergonomics Society, 1994-12-01)
A series of three studies was conducted to explore the use of tactile stimulation or light tapping of the human head to inform a pilot of possible threats or other situations in the flight environment. Study I confirmed ...
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 ...
A Prediction Model for Consumer Behavior regarding Product Safety
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1986-09-01)
The objective of this study was the development of a model to predict whether a consumer would use a product safely as a function of sixteen different individual variables. Subjects were presented with four consumer products ...
