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 ...
Observations on Infrared Radiation at the Workplace
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1980-10-01)
A discussion of the use of radiant heating in sedentary workplaces is presented. The advantages of the approach with respect to energy conservation are emphasized along with accompanying effects on worker comfort and ...
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 ...
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 ...
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 ...
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 ...
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 ...
Training Characteristics of the Criterion Task Set Workload Assessment Battery
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1985-10-01)
An evaluation of the Criterion Task Set was performed to determine the training requirements for the various tasks. Twenty subjects were divided into four groups. One group trained on all nine tasks in the battery. The ...
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 ...
