Used to analyze and interpret sonar data for landmark identification and navigation, this method involves: 1) putting a human operator within a telerobotic loop; 2) studying the capabilities and limitations of the operator for different tasks; 3) using protocol analysis to extract the knowledge from the operator into an expert system; 4) substituting the expert system for the operator within the robotic loop. A central aspect of the MRS methodology is that the operator, through the telerobotic interface, is limited to the same sensor information as the robot. The strength of this methodology is shown through the development of door identification and door traversal performances by an autonomous mobile robot using ultrasonic data.

First, two previous metrics from the literature, integrality [1] and inefficiency [2], are reviewed. To summarize these metrics, integrality is a measure of the simultaneity of motion among multiple dofs. Integrality is measurement in the time dimension only, and says nothing about magnitude or the direction of the movement. Inefficiency, on the other hand, is a measurement of the length of the user's actual trajectory compared to the optimal trajectory. Inefficiency is a measurement in the spatial dimension only, and says nothing about the time course of the movements. The 0-metric uses a two-dimensional unit of measure, area, to measure both time and space. The basis behind the 0-metric and its method of computation is explained. Pilot data illustrating the 0-metric are presented for a simple 2 dof docking example, and a more complex 6 dof docking example. For wh...

Whereas previous metrics from the literature, efficiency and integrality, are measurements in the space and time domains respectively, coordination should be measured in both dimensions. This poster proposes a definition of coordination and hypothesizes as to what will be found. Keywords coordination, performance, integrality, efficiency, manual control, multiple degrees of freedom, input devices

The 7/t-metric is a measurement definition which quantifies the allocation of control across multiple degrees of freedom. Allocation of control is defined as the product of two components, the simultaneity of control and the efficiency of control, corresponding to the time and space dimensions respectively. The existing human factors, biomedical, and motor control literature serves as the foundation for the development of the 7/t- metric. The 7/t-metric has several limitations including dependency upon the chosen coordinate system, assumptions of optimal trajectories, and the lack of frequency domain analysis.

The Federal Highway Administration is actively pursuing research to determine the minimum retroreflectivity requirements for pavement markings. In all cases, the research to determine minimum retroreflectivity requirements is based on drivers? minimum detection distances. As is no surprise, research to determine minimum detection distances has determined that brighter markings can be seen further away; there is an unwritten assumption is that increasing minimum detection distances increases safety. Unfortunately, there are situations, such as sharp curves with low design standards, where in fact increas...

It was recognized that integration was key to increase efficiency and effectiveness of reducing collision frequency and severity in a setting where funds are scant and pressure on infrastructure is growing. This paper provides a structured look at an integrated system (referencing Ottawa's), its components, and the process to address a road safety concern using one of the City's potential emphasis areas, "Increasing Safety of the City's Young Drivers."
