Authoring Effective Embedded Tutors: An Overview Of The Extensible Problem Specific Tutor (Xpst) System, Stephen B. Gilbert, Stephen B. Blessing, Enruo Guo 2015 Iowa State University

Authoring Effective Embedded Tutors: An Overview Of The Extensible Problem Specific Tutor (Xpst) System, Stephen B. Gilbert, Stephen B. Blessing, Enruo Guo

Industrial and Manufacturing Systems Engineering Publications

The Extensible Problem Specific Tutor (xPST) allows authors who are not cognitive scientists and not programmers to quickly create an intelligent tutoring system that provides instruction akin to a model-tracing tutor. Furthermore, this instruction is overlaid on existing software, so that the learner’s interface does not have to be made from scratch. The xPST architecture allows for extending its capabilities by the addition of plug-ins that communicate with additional third-party software. After reviewing this general architecture, we describe three major implementations that we have created using the xPST system, each using different third-party software as the learner’s interface ...

Virtual Operator Modeling Approach For Construction Machinery, Yu Du, Michael C. Dorneich, Brian L. Steward, Eric R. Anderson, Lawrence F. Kane, Brian J. Gilmore

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Greater understanding of how highly skilled operators achieve high machine performance and productivity can inform the development of automation technology for construction machinery. Current human operator models, however, have limited fidelity and may not be useful for machinery automation. In addition, while physical modeling and simulation is widely employed in product development, current operator simulation models may be a limiting factor in assessing the performance envelope of virtual prototypes. A virtual operator modelling approach for construction machinery was developed. Challenges to the development of human operator models include determining what cues and triggers human operators use, how human operators make ...

Flight Deck Information Automation: A Human-In-The-Loop In-Trail Procedure Simulation Study, Emmanuel Letsu-Dake, William Rogers, Stephen D. Whitlow, Michael Dillard, Michael C. Dorneich, Rachel Dudley

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Information automation systems are generally intended to support pilot tasks and improve flightcrew awareness and decision making, but not to directly control the aircraft or its systems. As a result these systems do not include cases where automation decisions and actions directly affect the aircraft performance, flight path or systems. Next Generation Air Transportation System (NextGen) operational concepts and technologies will dramatically affect both the types and amount of information available on flight decks. Much of that information will be produced by flight deck information automation systems that collect, process, and present that information to the flightcrew. It is therefore ...


Incorporation Of Future Building Operating Conditions Into The Modeling Of Building–Microclimate Interaction: A Feasibility Approach, Kelly Kalvelage, Ulrike Passe, Caroline Krejci, Michael C. Dorneich 2015 Iowa State University

Incorporation Of Future Building Operating Conditions Into The Modeling Of Building–Microclimate Interaction: A Feasibility Approach, Kelly Kalvelage, Ulrike Passe, Caroline Krejci, Michael C. Dorneich

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

This paper presents a novel modeling methodology that integrates the near building environmental conditions (or microclimate), whole-building design, and occupant behavior. Accurate predictions of the future building operating conditions lead to designs that serve the building’s purpose – to support occupants’ tasks. This study bridges the gap between human factors and architecture to include physical, cognitive, and organizational systems into building information modeling using future typical meteorological year climate data, canyon air temperature microclimate model, and a whole-building energy simulation to investigate the impact of future microclimate conditions on a “typical” single-occupant office. Additionally, to capture the effects of building ...

Process Improvements Of Cilantro Harvesting With Ergonomic Considerations, Eric Penningroth, Branden Shimamoto

Industrial and Manufacturing Engineering

The problems presented by Talley Farms to the team were a lower than desired cilantro harvesting capacity and work health pertaining to lower back problems. The project objectives were to address and improve upon both of these objectives. To increase harvesting capacity, a simulation model was created using standard times from time studies. The simulation model helped to compare the different harvesting methods as well as the effect of the utilization of the on-site manager. The throughputs between each of the models were analyzed. To address ergonomic concerns, a work sampling study was conducted and it was determined that kneeling ...


Control And Resilience Within The Maritime Traffic Management Domain, Gesa Praetorius 2014 Selected Works

Control And Resilience Within The Maritime Traffic Management Domain, Gesa Praetorius

Gesa Praetorius

This article presents research conducted within the Vessel Traffic Service (VTS) domain. VTS is a service that is provided close to ports and geographically challenging areas to support merchant vessels in their navigation. Although VTS is legally an advice and assistance service, applying concepts from Cognitive Systems Engineering and Resilience Engineering can highlight how the joint human-machine system works to promote safe and efficient traffic movements. The VTS is a Joint Cognitive System that maintains control through a mixture of opportunistic and tactical control. Strategic control is only partially supported by the higher levels of system aggregation that provide the ...

Vessel Traffic Service (Vts): A Maritime Information Service Or Traffic Control System? Understanding Everyday Performance And Resilience In A Socio-Technical System Under Change, Gesa Praetorius

Gesa Praetorius

Vessel Traffic Service (VTS) is a shore-side maritime assistance service that supports bridge teams in their safe navigation of port approaches and other areas that present navigational difficulties. The VTS is implemented in national waters and provides vessels with information through transmissions and broadcasts on Very High Frequency (VHF) radio. With a continued growth in the number, size and cargo volumes of merchant vessels, the role of the VTS has recently become a matter of discussion, and it has been argued that changes, such as implementing an aviation-like control system, would be of an enormous benefit for stakeholders and guarantee ...

Taxonomy Of Teams, Team Tasks, And Tutors, Desmond Bonner, Stephen B. Gilbert, Michael C. Dorneich, Shawn Burke, Jamiahus Walton, Colin Ray, Eliot H. Winer

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

While significant research has been done on teams and teaming (Salas, et al. 2004), less work has been done to characterize teams and team tasks in terms of the feasibility for them to benefit from intelligent tutoring. This theoretical paper begins to describe how the parameters of team structures addressed may affect the ways in which a team can accommodate external guidance. In addition, parameters of team tasks and resulting team tutors are also described. Examples of both team structures and team tasks are provided so that the resulting theoretical framework offers guidance for design decisions during the construction of ...

Modality And Timing Of Team Feedback: Implications For Gift, Jamiahus Walton, Michael C. Dorneich, Stephen B. Gilbert, Desmond Bonner, Eliot H. Winer, Colin Ray

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

This paper discusses considerations relevant to the design of team feedback in intelligent tutoring systems (ITSs). While team tutoring is a goal for the Generalized Intelligent Framework for Tutoring (GIFT), further research must be done to explore the focus, modalities, and timing of feedback for teams. Alt-hough there have been a number of studies on feedback, there are a limited number of studies on feedback for teams. This theoretical paper leverages previous research on ITSs, training, individual feedback, and teamwork models to inform appropriate decisions about the most effective feedback mechanisms for teams. Finally, the implications of team feedback on ...

A Natural User Interface For Immersive Design Review, Anastacia Macallister, Eliot H. Winer, Siemens Plm Software, The Boeing Company

Mechanical Engineering Conference Presentations, Papers, and Proceedings

As markets demand engineered products faster, waiting on the cyclical design processes of the past is not an option. Instead, industry is turning to concurrent design and interdisciplinary teams. When these teams collaborate, engineering CAD tools play a vital role in conceptualizing and validating designs. These tools require significant user investment to master, due to challenging interfaces and an overabundance of features. These challenges often prohibit team members from using these tools for exploring alternatives. This paper presents a method allowing users to interact with a design using intuitive gestures and head tracking, all while keeping the model in a ...


Investigating Teenage Drivers' Driving Behavior Before And After Lag (Less Aggressive Goals) Training Program, Jingyi Zhang 2014 University of Massachusetts Amherst

Investigating Teenage Drivers' Driving Behavior Before And After Lag (Less Aggressive Goals) Training Program, Jingyi Zhang

Masters Theses

Motor vehicle crashes are a leading cause of death during adolescence, with the fatal crash rate per mile-driven for 16-19 years old drivers being nearly 3 times larger than the rate for drivers age 20 and older. High gravitational events among teenage drivers, such as quick starts, and hard stops, have been shown to be highly correlated with crash rates. The current younger driver training programs developed in the late 1990s, however, do not appear to be especially effective in regard to many skills which are critical to avoiding crashes. With this in mind, a simulator-based training program aimed at ...


Instructional Strategies In Diagram-Based Itss: Lessons Learned From Two Tutoring Systems, Enruo Guo, Stephen B. Gilbert 2014 Iowa State University

Instructional Strategies In Diagram-Based Itss: Lessons Learned From Two Tutoring Systems, Enruo Guo, Stephen B. Gilbert

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Unlike text-based input to an intelligent tutoring system, a diagram is perceived as a whole state; the operation sequence is less important. Traditional step-wise coaching is not as appropriate in diagram-based intelligent tutoring systems (DITS). From two previous tutoring systems, StaticsTutor and Thermo Cycle Tutor, we propose cross-domain pedagogical guidelines for DITS. In particular, instruction needs to be mapped to a hierarchical understanding of the diagram, where each level focuses on different characteristics of the drawing. Also, instruction needs to address conceptual knowledge and procedure expertise separately. Some practical suggestions are described to achieve these goals, such as 1) different ...

Fusing Self-Reported And Sensor Data From Mixed-Reality Training, Trevor Richardson, Stephen B. Gilbert, Joseph Holub, Frederick Thompson, Anastacia Macallister, Rafael Radkowski, Eliot Winer, Paul Davies, Scott Terry

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Military and industrial use of smaller, more accurate sensors are allowing increasing amounts of data to be acquired at diminishing costs during training. Traditional human subject testing often collects qualitative data from participants through self-reported questionnaires. This qualitative information is valuable but often incomplete to assess training outcomes. Quantitative information such as motion tracking data, communication frequency, and heart rate can offer the missing pieces in training outcome assessment. The successful fusion and analysis of qualitative and quantitative information sources is necessary for collaborative, mixed-reality, and augmented-reality training to reach its full potential. The challenge is determining a reliable framework ...

Effective joint human-automation coordination is essential in order to support the central role of the human operator in foreseen future trajectory-based air traffic operations. The SESAR WP-E project C-SHARE aims to achieve this by taking a Cognitive Systems Engineering approach, based upon accomplishing joint human and automation cognition through a shared representation of 4D-trajectory management. In foregoing research, a work domain model and a joint human-machine interface has been developed to support the human operator in the task of en-route 4D trajectory re-planning. This paper presents the findings of two experiments that aimed to determine the effect of both the ...
