Williams Seed Grant Funds Virtual Keyboard Research

Published

Siva Krishna Kakula and Zachary GaravetBy Karen Johnson, ICC Communications Director

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.

Williams Seed Grant Funds Underwater Acoustic Communications Research

Published

Zhaohui WangBy Karen Johnson, ICC Communications Director

Underwater acoustic communication has been in use for decades, but primarily for military applications. In recent years, private sectors such as environmental monitoring, off-shore oil and gas exploration, and aquaculture have become interested in its possibilities.

But existing research about underwater acoustic communication networks often relies on human-operated surface ships or cost-prohibitive autonomous underwater vehicles (AUVs). And these cost barriers can limit academic research evaluation to computer simulations, constraining research innovation towards practical applications.

Recognizing the above gap, Michigan Tech Institute of Computing and Cybersystems (ICC) researchers Zhaohui Wang, assistant professor, Electrical and Computer Engineering, and Nina Mahmoudian, adjunct professor, Mechanical Engineering-Engineering Mechanics, saw an opportunity to combine their areas of expertise: for Wang, underwater acoustic communications, for Mahmoudian, low-cost marine robotics and AUVs.

Also part of the research team were PhD student Li Wei, Electrical and Computer Engineering, and post-doc research engineer Barzin Moridian, Mechanical Engineering-Engineering Mechanics. The team also collaborated with scientists at Michigan Tech’s Great Lakes Research Center.

With a $50K seed grant from Electrical and Computer Engineering alumnus Paul Williams ’61, the team took the research beneath the surface to develop a low-cost marine mobile infrastructure and investigate the challenges and possible solutions in engineering a leading-edge AUV communication network.

They broke it down into three areas: the development of low-cost, high-modularity autonomous surface vehicles (ASVs), each equipped with a collection of sensors and serving as surrogates for AUVs; equipping each ASV with an acoustic modem and implementing communication and networking protocols to facilitate underwater communication among the vessels; and conducting field experiments to collect data about the fundamental challenges in mobile acoustic communications and networking among AUVs.

The team’s outcomes included two low-cost, autonomous, on-the-water boats; an experimental data set, data analysis, and preliminary results; a technical paper presented at the 2018 IEEE OES Autonomous Underwater Vehicle Symposium; and a marine mobile wireless networking infrastructure for use in continued research.

Just half of their seed grant has been used, and this summer Wang and Mahmoudian will work to improve the boats and the communications system, and conduct more field research. In addition, they are planning to write two National Science Foundation proposals to take their research even further.

Tim Schulz Selected for Deans’ Teaching Showcase

Published

Timothy Schulzby Michael R. Meyer, Director William G. Jackson CTL

College of Engineering Dean Janet Callahan has selected Tim Schulz (ECE) as the final member of the 2019 Deans’ Teaching Showcase.  As a teacher he is widely acknowledged as one of the ECE departments best, with his friendly, humorous style and his devotion to his students’ learning.  But Schulz’s selection here is, according to Associate Dean Leonard Bohmann for his “leadership in using technology to deliver technical material in electrical and computer engineering.”

Starting in 2012, Schulz created a series of 10 to 15 minute videos collectively titled “Electric Circuits” and posted them on YouTube.  Though he created them with his EE2111 (Electric Circuits 1) class in mind, they are reaching a much wider audience.  In fact, one titled “Introduction to Thevenin Equivalent Circuits” has gotten more than 152,000 views.

Since that time, Schulz has also developed a phone app of randomized electric circuit problems to use in this course. He develops these aids so students can develop a mastery of the course material. As one student noted, “The videos and the infinite practice problems were the most helpful. As much as I hate to say this, the quizzes were also helpful.”

In his courses, Schulz develops from scratch his own interactive web-based approach to homework sets and quizzes, taking full advantage of the capabilities of Canvas and writing his own scripts for generating homework problems with randomized parameters. His colleagues recognize this, and some have adopted Schulz’s materials when they teach the same classes.

Most recently, Schulz has taken the lead in developing new courses for the online MSEE program with a focus on communications and signal processing, in partnership with Keypath Education, Inc. He developed and is teaching for the second time, EE5300, Mathematical and Computational Methods in Engineering, which is the entry point into the program.

His course engages students through a series of interactive MATLAB computational exercises which meet modern standards for online course delivery and are breaking new ground for the ECE Department.

Students find this approach to be very helpful. One said, “The canvas structure paired with the lecture truly was a great combination. The prep work must have been substantial but was well worth it.”

Another provides even broader praise of both Schulz and the course by saying, “The course is excellent and engaging. Overall, I think this class is a must for any student wishing to have a solid starting foundation in graduate studies in engineering. Dr. Schulz is an outstanding professor with extensive research and professional experience and I would totally recommend students to take this class.”

Schulz is currently developing the third course for the online MSEE program, EE5500  Probability and Stochastic Processes, which will be taught for the first time this summer. He agrees that developing an online course is much more rigorous then teaching face-to-face, saying “You need to do more planning of how to approach a topic.  You don’t have the ease of correcting an approach (or even an equation) in real time, so it is a much more deliberate process.”

However, this higher level of rigor is a challenge he enjoys; he’s already signed on to develop his next course, EE5521 Detection and Estimation Theory, which will be offered online for the first time sometime in 2020-2021 academic year.

Callahan emphasizes that it’s really about the technology enabling better learning. In her words, “Tim Schulz’s effective use of technology shows that student learning and satisfaction can both increase with the use of modern tools.”

Schulz will be recognized at an end-of-term luncheon with other showcase members and is now elgible for one of three new teaching awards to be given by the William G. Jackson Center for Teaching and Learning this summer recognizing introductory or large class teaching, innovative or outside the classroom teaching methods, or work in curriculum and assessment.

Smart traffic is more than self-driving cars. One engineer is tackling these transportation systems with an early career award grant from the National Science Foundation (NSF).

Changing lanes, upcoming merges, blind spots — wouldn’t it be great to broadcast to other vehicles what your own car is doing and where? Well, the technology does exist, and the data-rich messages in vehicle-to-vehicle communication are less salty than the ones exchanged in human languages. But the technology needs more development before it’s ready for rush hour.

Kuilin Zhang explained the challenge is forecasting traffic, which is inherently uncertain. Zhang, assistant professor of civil and environmental engineering and affiliated assistant professor of computer science at Michigan Tech, is a recipient of an NSF CAREER Award to improve automated driving decisions using predictive, real-time feedback within and between vehicles. The project totals $500,000 over a five-year span and puts some of Michigan Tech’s prime mobility testing facilities to use.
