Variable Strategy Model of the Human Operator
Human operators often employ discontinuous or "bang-bang" control strategies when performing large-amplitude acquisition tasks. The current study applies Variable Structure Control (VSC) techniques to model human operator behavior during acquisition tasks. The result is a coupled, multi-input model …

Projection Methods for Order Reduction of Optimal Human Operator Models
Human operator models developed using optimal control theory are typically complicated and over-parameterized, even for simple controlled elements. Methods for generating less complicated operator models that preserve the most important characteristics of the full order model are developed so that …

Gamification as a means of improving performance in human operator processes
… and retrieve shelving units, delivering them to operators who can interact with product at fixed stations. This has greatly increased throughput in buildings with the technology, while adding new constraints. During periods of peak demand, throughput is limited by the number of stations available …

Effect of Time Pressure and Task Uncertainty on Human Operator Performance and Workload for Autonomous Aerial Vehicle Missions
… of flying unmanned aircraft. The role of a UAS operator differs from that of a pilot in a manned aircraft, and this new role creates a need for a shift in interface and task design in order to take advantage of the full potential of these systems. This study examined the effect of time pressure …

On-line task scheduling and trajectory planning techniques for reconnaissance missions with multiple unmanned aerial vehicles supervised by a single human operator
The problem of a single human operator monitoring multiple UAVs in reconnaissance missions is addressed in this work. In such missions, the operator inspects and classifies targets as they appear on video feeds from the various UAVs. In parallel, the aircraft autonomously execute a flight plan and …

Obstacle Avoidance and Path Traversal Using Interactive Machine Learning
… that are dangerous or cost prohibitive for humans to do. Such activities include military uses and space exploration. While robotic hardware is often capable of being used in these types of situations, the ability of human operators to control robots in an effective manner is often limited. …

Cooperative human-robot search in a partially-known environment using multiple UAVs
… in a partially-known environment, with a human operator, and two Unmanned Aerial Vehicles (UAVs) with nadir, and front on-board cameras. The system uses two phases of flight operations, where the first phase is aimed at gathering latest overhead images of the environment using a UAV’s …

Extra robotic legs for augmenting human payload and positioning capabilities
… (XRL) system is a robotic augmentation worn by a human operator that consists of two articulated robot legs that help bear a heavy backpack payload and a portion of the operator's own weight. The design was driven by a need to increase the effectiveness of Department of Energy hazardous material …

Dynamic Obstacle Avoidance on a Self-balancing Robot Platform
… parking themselves. These tasks often involve a human operator that has some high level control over the system. This can lead to situations where the human operator believes that the system is safe, when this might not be the case. This is why robust control algorithms need to be implemented …

Human robotic swarm interaction using an artificial physics approach
… a collection of agents in close proximity to a human operator. Based on the spatial separation between agents, agents to way-point, and agents to operator, the artificial physics framework calculates virtual forces that are summed and translated into velocity commands. The virtual forces are …

Formalizing operator task analysis
Human operators are unique in their decision making capability, judgment and nondeterminism. Their sense of judgment, unpredictable decision procedures, susceptibility to environmental elements can cause them to erroneously execute a given task description to operate a computer system. Usually, a …

Human Problem Solving in Process Control
… illustrated. It is argued that the role of the human operator is evolving to be primarily that of a problem solver. Following a brief review of literature related to problem solving from the areas of psychology and process control, it is noted that the general opinion reflected in these sources …
