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 ...
Biomechanical Analysis of Postural Sway in Elderly Adults on Ramps
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2001-10-01)
This study investigated the effects of ramp angles on postural deviation as a function of age. Five ramp inclinations (1:8, 1:10, 1:12, 1:16, and 1:20) were examined in both ascent and descent directions. Five younger (22 ...
A Survey of Ramp and Stair Use among Older Adults
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2000-07-01)
Forty-three community-dwelling adults aged 57 to 95 participated in survey exploring characteristics of ramp use by older ambulant people. Twenty-three respondents said they ascended ramps instead of stairs most of the ...
Effectiveness of 2-D Views for 6-D Robotics Simulation Maneuvers
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2003-10-01)
This study examined operator performance on 6-D robotics simulation maneuvers using a single 2-D view of the robot arm. The BORIS simulator, developed by NASA to support Generic Robotics Training, was used to present four ...
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 ...
Package Opening: An Evaluation of Opening Tools for the Elderly Population
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2005-09-01)
Opening packages is becoming more difficult with manufacturers making packaging harder to tamper with. Consumers must apply greater force or use tools to aid them in opening. With aging, the amount of force that can be ...
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 ...
Movement Kinematics and their Relationship with Performance in Target Acquisition Task Using a Mouse
(Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2007-10-01)
Movement kinematics has been shown useful for characterizing the process of aiming movement in target acquisition tasks. There are multiple kinematic measures reported in the literature, but their relationship to eventual ...
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 ...
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 ...
