Samantha Smith to Present Talk for ACSHF Forum

The first Applied Cognitive Science and Human Factors (ACSHF) Forum of the Spring 2020 semester will be held from 2 to 3 p.m. Monday (Jan. 13) in Meese 109. Samantha Smith (CLS), will present “The Relationship between Cerebral Hemovelocity and Vigilance: Sample versus Individual Outcomes, and Future Directions.”

High workload, stress, and fatigue may negatively impact operator performance in critical roles. A means to monitor ongoing performance would be useful to intercede when deficits are detected, but it is not often possible to detect these deficits in real-world tasks, in real-time. However, it has shown that cerebral blood flow velocity (CBFV), a measure of changes in cognitive metabolic activity, declines alongside performance in sustained attention tasks. Thus, CBFV has been proposed as a potential way to monitor operators for indirect insight into cognitive state and performance.

This presentation will discuss a recent study exploring the relationship between CBFV and vigilance performance at the sample versus individual level and will propose the use of Recurrence Quantification Analysis to further explore the complex relationship between psychophysiological metrics and cognitive performance over time.


BASIC Program Featured on TV 6-WLUC UPSide

Kelly Steelman

Building Adult Skills in Computing, or BASIC, is a program where anyone in the community who has questions about computers, smart phones, or tablets, can receive individual instruction. The BASIC program tutors, all Michigan Tech students, and faculty mentor Kelly Steelman, member of the ICC’s Center for Human-Centered Computing, were featured on the TV6 feature UPsiders on November 25, 2019.

View the video on Facebook here: https://www.facebook.com/uppermichiganssource/videos/2669673899926711/.

More about BASIC:

Since 2011, Michigan Tech students and faculty have been helping Copper Country community members improve their basic computer skills through the free tutoring program Building Adult Skills in Computing (BASIC).

The sessions take place every Saturday morning from 10:00 to 11:00 at the Portage Lake District Library, Houghton, when Michigan Tech classes are in session. Up to 15 tutors are available this semester and all community members are welcome. Computer experience is not necessary and an appointment is not required.

“As the digital revolution continues to transform our society, many older adults and other groups are being left behind,” said Charles Wallace, associate professor of computer science. “Using computers, smartphones and other digital devices remains unfamiliar territory for many and it can be a source of great anxiety.”

Wallace explains that through this free tutoring, the BASIC program aims to overcome this anxiety and build the computer skills and digital literacy needed for participants to effectively operate digital devices and technology and safely find the information they need.

For more information, please contact Charles Wallace (906-487-3431, wallace@mtu.edu) or Kelly Steelman, associate professor of cognitive and learning sciences (906-487-2792, steelman@mtu.edu).

ACSHF Forum Monday

Beth Veinott

One challenge affecting a variety of teams, such as software development, engineering, military, and crisis management, is overconfidence in the effectiveness of their plans.  Referred to as the planning fallacy, Buehler et al. (1994) suggests that ignoring past failures is a key cognitive element in this phenomenon. This talk summarizes recent experiments examinin the effect of counterfactual reasoning strategies, thinking about what might have happened under different circumstances, on people’s reasons, confidence and predictions.

Leveraging a collaborative, structured analytic technique called the Premortem, this project extends research on counterfactual reasoning to estimates in planning. The results will be discussed in the context of advances in machine learning, AI, and crowdsourcing that have changed the information available to teams.


Charles Wallace is Associate Dean for Curriculum and Instruction

Charles Wallace

Charles Wallace, Associate Professor of Computer Science and member of the ICC’s Center for Human-Centered Computing, has been appointed Associate Dean for Curriculum and  Instruction for the College of Computing, effective immediately. Wallace has been teaching in the Department of Computer Science for 19 years, and he has a long track record of education research and building collaboration with Cognitive & Learning Sciences, Engineering, Humanities, and Social Sciences.

“Chuck brings to his new role an extensive breadth of experience that spans from outreach to curricular development to collaborations with multiple units across campus,” says Adrienne Minerick, dean of the College of Computing. “In this new role, he will help build campus collaborations to create additional pathways for Michigan Tech students to engage with computing curricula, and facilitate conversations within the College of Computing that enable creative, agile options for our students.”

“Barriers between computing and other disciplines are artificial and unproductive,” Wallace says. “Computing competencies are essential for Michigan Tech graduates in all fields, and the College and University should commit to building educational options housed in the College of Computing but available and accessible to all students.”

Wallace adds that students in the College of Computing should be free – and actively encouraged – to explore application areas where their skills can be used. He also wants to explore ways to build flexibility into Computing academic programs, maintaining the solid technical core that Michigan Tech graduates are known for, but also allowing students to pursue applications of their computing competencies in other disciplines.

Vision Statement from Charles Wallace:

Here are a few points that I consider vital to the future of computing education, based on 19 years of experience in the Computer Science Department, a long track record of education research, and extensive collaboration with Cognitive & Learning Sciences, Engineering, Humanities, and Social Sciences.

Barriers between computing and other disciplines are artificial and unproductive.  Computing competencies are essential for Michigan Tech graduates in all fields.  The College and University should commit to building educational options housed in the College of Computing but available and accessible to all students.  This will require an earnest and focused investment in personnel – we cannot do it solely with the current cohort of instructors, who are already stretched thinly with increased enrollment in core computing programs.

Conversely, students in the College of Computing should be free and even encouraged to explore application areas where their skills can be brought to bear.  Complex degree requirements can hinder such exploration.  We should explore ways to build flexibility into our programs, maintaining the solid technical core that Michigan Tech graduates are known for, but also allowing students to pursue applications of their computing competencies in other disciplines.

Computing students are citizens, not just producers.  The degree programs in Michigan Tech’s Computer Science Department have a long and venerable tradition of preparing students who can “produce” – hit the ground running in the workplace and build high quality solutions. That is a precious gift, and we should not deprive future students of it – but the future demands more. Our world is increasingly dominated by computing – and by extension, dominated by human beings who understand computing. Michigan Tech graduates of the College of Computing must be known not only for the technical “value” that they produce, but also the ability to question and critique digital technology, to be empathetic and articulate ambassadors and leaders in the new digital order of the future.

There are two promising ways in which we can build better computing citizens. First, an awareness of the social and ethical consequences of computing must be woven into our curricula, not just taught as external service courses.  Second, service learning is a way to expose students to the human contexts of computing technology. There are many ways to get students involved in our community, but these have not been harnessed outside of ad hoc outreach efforts. Interaction with the community should be built into the academic experience of computing students.

Computing competencies include values and attitudes, not just skills and knowledge. Alumni of our degree programs acknowledge that collaboration and communication are essential components of their professional lives.  These competencies involve not only skills but also values and attitudes – willingness and even eagerness to engage with others, resilience in the face of uncertainty or ambiguity, and adaptability in the face of changing requirements.  To prepare students for the highly collaborative computing workplace, courses in the College of Computing should embrace the opportunities and challenges of working in diverse teams. As with ethics, issues of teamwork and communication must be integrated into “disciplinary” courses, not left to service courses or external experiences like internships.

These curricular pathways hold promise not only to develop competent computing professionals of the future, but also to attract a more diverse constituency to the College of Computing student body.


Keith Vertanen Is PI on $225K NSF Grant, “Improving Mobile Device Input for Users Who are Blind or Low Vision”

Keith Vertanen

Keith Vertanen (CS/ICC-HCC) is the principal investigator on a three-year project that has received a $225,663 research and development grant from the National Science Foundation. The project is entitled, “CHS: Small: Collaborative Research: Improving Mobile Device Input for Users Who are Blind or Low Vision.”

Abstract: Smartphones are an essential part of our everyday lives. But for people with visual impairments, basic tasks like composing text messages or browsing the web can be prohibitively slow and difficult. The goal of this project is to develop accessible text entry methods that will enable people with visual impairments to enter text at rates comparable to sighted people. This project will design new algorithms and feedback methods for today’s standard text entry approaches of tapping on individual keys, gesturing across keys, or dictating via speech. The project aims to:  1) help users avoid errors by enabling more accurate input via audio and tactile feedback, 2) help users find errors by providing audio and visual annotation of uncertain portions of the text, and 3) help users correct errors by combining the probabilistic information from the original input, the correction, and approximate information about an error’s location. Improving text entry methods for people who are blind or have low vision will enable them to use their mobile devices more effectively for work and leisure. Thus, this project represents an important step to achieving equity for people with visual impairments.

This project will contribute novel interface designs to the accessibility and human-computer interaction literature. It will advance the state-of-the-art in mobile device accessibility by: 1) studying text entry accessibility for low vision in addition to blind people, 2) studying and developing accessible gesture typing input methods, and 3) studying and developing accessible speech input methods.  This project will produce design guidelines, feedback methods, input techniques, recognition algorithms, user study results, and software prototypes that will guide improvements to research and commercial input systems for users who are blind or low-vision. Further, the project’s work on the error correction and revision process will improve the usability and performance of touchscreen and speech input methods for everyone.

What if an everyday surface, like a table, could be transformed into a rich, interactive surface that can remotely operate things like computers, entertainment systems, and home appliances?

That’s what Michigan Tech Institute of Computing and Cybersystems (ICC) researchers Keith Vertanen and Scott Kuhl set out to do with a $44K seed grant from Electrical and Computer Engineering alumnus Paul Williams ’61.

Vertanen, assistant professor of computer science, and Kuhl, associate professor of computer science, are members of the ICC’s Center for Human-Centered Computing, which integrates art, people, design, technology, and human experience in the research of multiple areas of human-centered computing. They were assisted in this research by PhD candidate Siva Krishna Kakula, Computer Science, and undergraduate Zachary Garavet, Computer Engineering.

The team’s research goals were threefold: to create machine learning models that can precisely locate a user’s taps on a surface using only an array of inexpensive surface microphones; demonstrate the feasibility and precision of the models by developing a virtual keyboard interface on an ordinary wooden table; and conduct user studies to validate the system’s usability and performance.

The researchers are working on a related technical conference paper to present to their peers. Their outcomes included a prototype virtual keyboard that supports typing at rates comparable to a touchscreen device; possibly the first-ever acoustic sensing algorithm that infers a continuous two-dimensional tap location; and novel statistical models that quickly adapt to individual users and varied input surfaces.

Further, their results, hardware, and data sets can be applied to future collaborative work, and were used in the researchers’ $500K National Science Foundation proposal, “Text Interaction in Virtual and Augmented Environments,” which is under review.

Future applications of the research include enriched interactions in Virtual Reality (VR) and Augmented Reality (AR), compared to existing vision-only based sensing; and on-body interaction, like using your palm as an input surface.

Vertanen and Kuhl plan to continue this research, working to improve the accuracy of tap location inference, build richer interactions like swiping or tapping with multiple fingers, develop wireless sensor pods that can be quickly and easily deployed on any flat surface, and explore the display of virtual visual content on surfaces via Augmented Reality smartglasses.
