Relations among Multiple Workload Measure during a Memory Task

Autor: Arthur M. Ryan

Publikováno v: Proceedings of the Human Factors and Ergonomics Society Annual Meeting. 44:3-193

The present study examined the utility of Sanders' (1983) cognitive-energetic model of multiple levels of attentional mechanisms for predicting physiological, performance, and subjective responses to manipulations of computational demand. Sanders' (1

Multimodal Measures of the Energetic Demands of Information Processing in a Suboptimal Environment

Autor: Arthur M. Ryan, Richard W. Backs

Publikováno v: Proceedings of the Human Factors and Ergonomics Society Annual Meeting. 37:1393-1397

Twenty-four male volunteers participated in a study in which the feature extraction and response choice information processing stages of a visual memory task and the environment in which the task was performed were manipulated in order to assess the

Multimodal Measures of Mental Workload during Dual-Task Performance: Energetic Demands of Cognitive Processes

Autor: Richard W. Backs, Arthur M. Ryan

Publikováno v: Proceedings of the Human Factors Society Annual Meeting. 36:1413-1417

Fifteen male volunteers participated in a dual-task study in which the central processing load of visual memory and tracking tasks and the physical load of the tracking task were orthogonally manipulated to produce varying levels of task difficulty.

Cardiorespiratory Measures of Workload during Continuous Manual Performance

Autor: Richard W. Backs, Arthur M. Ryan, Glenn F. Wilson

Publikováno v: Proceedings of the Human Factors Society Annual Meeting. 35:1495-1499

Twelve subjects (six female) participated in a study designed to experimentally separate the effects of physical and cognitive effort on cardiac and pulmonary measures of workload. Cardiac (heart rate and variability), respiratory, and forearm muscle

Psychophysiological measures of workload during continuous manual performance

Autor: Richard W. Backs, Arthur M. Ryan, Glenn F. Wilson

Publikováno v: Human factors. 36(3)

Twelve subjects (six female) participated in an experiment designed to separate the effects of perceptual/central and physical demands on psychophysiological measures of peripheral nervous system activity. The difficulty of a single-axis continuous m

Application of a laser scanner to three-dimensional visual sensing and enhancement tasks

Autor: Arthur M. Ryan, Lester A. Gerhardt

Publikováno v: SPIE Proceedings.

This paper describes the issues associated with using a laser scanner for visual sensing and the methods developed by the authors to address them. A laser scanner is a device that controls the direction of a laser beam by deflecting it through a pair

Three-Dimensional Vision

Autor: Arthur M. Ryan, Lester A. Gerhardt, J. Russell Noseworthy

Publikováno v: Intelligent Robotic Systems for Space Exploration ISBN: 9781461366164

Three-dimensional vision refers to the process of gathering, processing, and interpreting visual data of a three-dimensional environment. A 3-D vision system may employ either passive or active techniques. A passive technique is one that utilizes ava
