The Challenges Of Building Intelligent Tutoring Systems For Teams, Desmond Bonner, Stephen B. Gilbert, Michael C. Dorneich, Eliot Winer, Anne M. Sinatra, Anna Slavina, Anastacia Macallister, Joseph Holub

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Intelligent Tutoring Systems have been useful for individual instruction and training, but have not been widely created for teams, despite the widespread use of team training and learning in groups. This paper reviews two projects that developed team tutors: the Team Multiple Errands Task (TMET) and the Recon Task developed using the Generalized Intelligent Framework for Tutoring (GIFT). Specifically, this paper 1) analyzes why team tasks have significantly more complexity than an individual task, 2) describes the two team-based platforms for team research, and 3) explores the complexities of team tutor authoring. Results include a recommended process for authoring a ...


Developing Game-Based Learning Requirements To Increase Female Middle School Students Interest In Computer Science, Desmond Bonner, Michael Dorneich Sep 2016

Developing Game-Based Learning Requirements To Increase Female Middle School Students Interest In Computer Science, Desmond Bonner, Michael Dorneich

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

This paper presents work on the development of a Game-Based Learning (GBL) application’s requirements for female middle school students which teaches fundamental concepts of programming. Currently, there are not enough students who desire to pursue Science, Technology, Engineering, and Mathematic (STEM) career fields. Additionally, female are underrepresented in STEM fields, and increased female participation may help partially address this gap. GBL was used to encourage middle school student interest in STEM by allowing them to practice computer science concepts in engaging contexts outside the classroom. The game Sorceress of Seasons was built to teach fundamental programming concepts, and was ...


Using Human Factors To Establish Occupant Task Lists For Office Building Simulations, Kelly Kalvelage, Michael Dorneich Sep 2016

Using Human Factors To Establish Occupant Task Lists For Office Building Simulations, Kelly Kalvelage, Michael Dorneich

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

The purpose of this research is to establish an in-depth understanding of task-related occupant behaviors toserve as the basis for the design of an occupant-building interaction interface. Building simulations arefrequently used to design buildings and predict energy performance. Yet, all of these assumptions are relatedto occupant behavior and interactions with the building. In an occupant-controlled environment, anunderstanding of the occupant decision-making process must be represented in the simulation task lists.Current task lists assume general occupant behaviors based on averages, and lack the details required for thisunderstanding. This paper looks to strike a balance between simplicity and complexity in the ...


Politeness In Machine-Human And Human-Human Interaction, Joachim Meyer, Chris Miller, Peter Hancock, Ewart De Visser, Michael Dorneich Sep 2016

Politeness In Machine-Human And Human-Human Interaction, Joachim Meyer, Chris Miller, Peter Hancock, Ewart De Visser, Michael Dorneich

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Computers communicate with humans in ways that increasingly resemble interactions between humans.Nuances in expression and responses to human behavior become more sophisticated, and they approachthose of human-human interaction. The question arises whether we want systems eventually to behave likehumans, or whether systems should, even when much more developed, still adhere to rules that aredifferent from the rules governing interpersonal communication. The panel addresses this issue fromvarious perspectives, eventually aiming to gain some insights into the question of the direction to which thedevelopment of machine-human communication and the etiquette implemented in the systems shouldmove.


Quantized Consensus Admm For Multi-Agent Distributed Optimization, Shengyu Zhu, Mingyi Hong, Biao Chen Jan 2016

Quantized Consensus Admm For Multi-Agent Distributed Optimization, Shengyu Zhu, Mingyi Hong, Biao Chen

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Abstract: This paper considers multi-agent distributed optimization with quantized communication which is needed when inter-agent communications are subject to finite capacity and other practical constraints. To minimize the global objective formed by a sum of local convex functions, we develop a quantized distributed algorithm based on the alternating direction method of multipliers (ADMM). Under certain convexity assumptions, it is shown that the proposed algorithm converges to a consensus within log1+η Ω iterations, where η > 0 depends on the network topology and the local objectives, and O is a polynomial fraction depending on the quantization resolution, the distance between initial ...

This paper describes the unexpected challenges of team tutor development such as the task and logistics. Previously, a research team from Iowa State University (ISU) working with the U.S. Army Research Laboratory (ARL) developed the reconnaissance (Recon) task for simple team tutoring with the Generalized Intelligent Framework for Tutoring (GIFT) (Bonner et al., 2015; Gilbert et al., 2015). Considerations were included for the testing environment such as audio-based team interactions, initialization of the scenario simultaneously, and the inclusion of eyetracking and screen capture technology. Throughout the process of tutor development, several computational challenges have been encountered such as the ...

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Virtual reality has grown rapidly over the past decade, yet visually induced motion sickness (VIMS),continues to affect the usability of this technology. Aside from medicine, physical hand-eye-coordinationtasks have been found to be effective in mitigating symptoms of VIMS, however the need for equipmentoutside of virtual reality limits the usefulness of these mitigation techniques. In this study, 21 participantswere sickened via a virtual obstacle course and used one of two mitigation techniques. The first, naturaldecay, is simply waiting outside the virtual environment (VE) for symptoms to subside; the other was avirtual peg-in-hole task, performed in the VE with a gamepad ...


The Effect Of Time Delay On Emotion, Arousal, And Satisfaction In Human-Robot Interaction, Euijung Yang, Michael Dorneich Sep 2015

The Effect Of Time Delay On Emotion, Arousal, And Satisfaction In Human-Robot Interaction, Euijung Yang, Michael Dorneich

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

This study investigates the influence of time delay on user emotion, arousal, and satisfaction in humanrobotinteraction (HRI). Time delay is a gap between an input from a user and the corresponding feedbackresponse from the system, and its negative consequence on performance has been documented in variousareas including psychology and HRI. On the contrary, the effects of time delay on user emotion andsatisfaction have been difficult to establish due to the fluctuations in the emotional aspect of thephysiological state of the user. In this study, the hypothesis of whether time delay during robot vehicleoperation increases user arousal and negative emotions while ...

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Work has been ongoing to develop an Intelligent Tutoring System (ITS) for teams. As part of this work, we are developing a flexible, scalable, military-based set of collaborative team tasks that can serve as a “testbed” to exercise various aspects of a team ITS architecture. Warfighting teams are a core part of any operation as individual soldiers combine their skill sets and plan, coordinate and act as one entity to accomplish assigned objectives. The team ITS test bed presented in this paper uses simple team tasks to train soldiers on basic functions including observation, target detection, target identification, communication within ...


Time-Optimal Path Planning For Automated Grain Carts, Mengzhe Zhang, Sourabh Bhattacharya Jan 2015

Time-Optimal Path Planning For Automated Grain Carts, Mengzhe Zhang, Sourabh Bhattacharya

Mechanical Engineering Conference Presentations, Papers, and Proceedings

In this paper, we address a motion planning problem for an autonomous agricultural vehicle modeled as tractor-trailer system. We first present a numerical approach and a primitive-based approach for computing the time-optimal path based on given static initial and goal configurations. In the former approach, we define a value function for the entire state space. The value function is consistent with the time to reach goal configuration, and it is finally used to compute the optimal trajectory. In the latter approach, based on the regular and singular primitives, we present an algorithm to construct such primitives and derive the final ...

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 ...

A Software Approach To Manage And Maintain Warfighter Training Systems, Ken Kopecky, Stephen B. Gilbert, Eliot H. Winer, Anthony Civitate, Julio De La Cruz

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

The use of simulation technologies in Warfighter training will need to increase as resource constraints tighten on the US military. Multiple studies have shown that simulation-based training promotes faster skills acquisition and assessment at greatly reduced cost and time. However, as these technologies become more pervasive, in a wider variety of training tasks, integrating them into a cohesive environment is increasingly complex.

Industries such as medical and construction use single purpose trainers to teach welding or suturing, but Warfighter training requires multiple systems, with unique capabilities, to interoperate. For example, it may be necessary for a ground-based Soldier trainer to ...

Analysis Of Tactors For Wearable Simulator Feedback: A Tactile Vest Architecture, David Prater, Stephen B. Gilbert, Eliot H. Winer

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Current training simulators for police officers and soldiers lack two critical qualities for establishing a compelling sense of immersion within a virtual environment: a strong disincentive to getting shot, and accurate feedback about the bodily location of a shot. This research addresses these issues with hardware architecture for a Tactical Tactile Training Vest (T3V). In this study, we have evaluated the design space of impact “tactors” and present a T3V prototype that can be viscerally felt. This research focuses on determining the optimal design parameters for creating maximum tactor hitting energy. The energy transferred to the projectile directly relates to ...

Space Perception In Virtual Environments: Displacement From The Center Of Projection Causes Less Distortion Than Predicted By Cue-Based Models, Jonathan W. Kelly, Melissa Burton, Brice Pollock, Eduardo Rubio, Michael Curtis, Julio De La Cruz, Stephen B. Gilbert, Eliot H. Winer

Industrial and Manufacturing Systems Engineering Publications

Virtual reality systems commonly include both monocular and binocular depth cues, which have the potential to provide viewers with a realistic impression of spatial properties of the virtual environment. However, when multiple viewers share the same display, only one viewer typically receives the projectively correct images. All other viewers experience the same images despite displacement from the center of projection (CoP). Three experiments evaluated perceptual distortions caused by displacement from the CoP and compared those percepts to predictions of models based on monocular and binocular viewing geometry. Leftward and rightward displacement from the CoP caused virtual angles on the ground ...
