A study of the difference between nominal and actual hand forces in two-handed sagittal plane whole-body exertions
Given a task posture, changes in hand force magnitude and direction with regard to joint locations result in variations in joint loads. Previous work has quantified considerable vertical force components during push/pull exertions. The objective of this work was to quantify and statistically model...
An eyellipse for rear seats with fixed seat back angles
This paper describes the development of the fixed seat eyellipse in the October 2008 revision of SAE Recommended Practice J941. The eye locations of 23 men and women with a wide range of stature were recorded as they sat in each of three second-row bench seats in a laboratory mockup. Testing was...
Influence of object weight and terminal orientation on upper limb postures during grasping, holding, and placing cylindrical object
This study examines the effect of object weight and terminal orientation on upper limb postures during grasping, holding, and placing cylindrical objects. An experiment including two sessions was conducted. In the first session, eight subjects grasped and held a horizontally located cylindrical...
A pilot study of biomechanical factors affecting upper limb posture during grasping, holding, and placing cylindrical object
A biomechanical analysis was performed to explain upper limb postures during grasping, holding, and placing cylindrical objects. This study is needed for ergonomic design of work equipment and methods to provide workers with sufficient control over objects in object transfer tasks.
Effect of in-vehicle touch screen position on driver performance
The effect of touch-screen monitor placement on in-vehicle task performance and driving performance was examined in a driving simulator. Sixteen subjects drove behind a lead vehicle while interacting with a menu-based interface that required looking, planning, reaching, and touching. The vehicle...
Identifying priorities for improving rear seat occupant protection
This project helped to identify priorities for improving the safety of rear seat occupants through a literature review and NASS-CDS injury analysis. The literature review covers injury patterns of rear seat occupants, new safety technologies intended for the rear seat, studies of rear seat belt and...
Ergonomics Research on Driver Distraction and Warnings
September 1, 2012 to June 29, 2013
Design Tools to Optimize Vehicle Ingress/Egress for Small Cars
Develop new data analysis methods to predict subjective evaluations based on driver ingress and egress motions.
Quantifying cervical-spine curvature using bezier splines
Knowledge of the distributions of cervical-spine curvature is needed for computational studies of cervical-spine injury in motor-vehicle crashes. Many methods of specifying spinal curvature have been proposed, but they often involve qualitative assessment or a large number of parameters. The...
