Under the exchange program five UNH ECE students spent the spring 2011 semester in Budapest. All five (picture above) were present at the information session to share their experiences with the eight juniors interested in the program (picture below).

The experiences we heard about were awesome, in fact life-changing. All five alumni of the exchange program agreed that spending a semester in Budapest was an excellent decision, with some calling it their “best decision.” The program was challenging, but that was one of its most important aspects because of the skills and confidence it built in each and every one of them. They all enjoyed their classes at BUTE, with one student describing a BUTE professor as the “best professor” he’s ever had – enthusiastic, knowledgeable, and helpful. For more on studying in Budapest, read the eceblogger posts by Carol Perkins, one of the five alumni of the program.

The juniors received instructions on administrative steps to take in order to participate in the program. These instructions were assembled by Kathy Reynolds and Caitlin Baldwin – thanks Kathy and Caitlin! Also thanks to József Porohnavec, a BUTE student spending a semester at UNH, for participating in the session.

As Kathy said in a follow-up email to the eight juniors: we can’t wait to hear their stories next fall when it is their turn to meet with the next group of students going to Budapest.

For the second year in a row the UNH ECE department has been selected by World Learning (WL) as a host institution for international exchange students participating in WL programs. WL is a non-profit organization that, according to its website, “provides education, exchange, and development programs that cultivate the global leadership and social innovation needed in a shrinking world.”

During the 2010-2011 academic year we hosted Angelica Sanabria from Honduras. Angelica participated in the WL UGRAD program. The picture to the left shows Angelica with her UGRAD Post image – UGRAD students use this image as a way to report on their travels around the US. Exploring the US, including by travel, is an integral part of the exchange program. During her time at UNH Angelica impressed me greatly as a smart and capable person. You can read more about her experiences at UNH on eceblogger.

During the 2011-2012 academic year, UNH ECE is hosting two students, smiling in the picture to the left. Huy Dong (left) has completed his freshman year at Vietnam National University, Ho Chi Minh City. Ivan Razumenic is a senior at the University of Belgrade, Serbia. Btw, Ivan is a blogger – take a look at his view of the WL FORECAST program and life in general on his blog.

I’m thrilled that WL has selected UNH as a host institution, and I’m really looking forward to working with both of our exchange students in the coming months. I am also greatful to the UNH CEPS Dean’s Office for their support in bringing in the exchange students.

Zeljko’s PhD committee includes Paul Green (UMTRI), Tim Paek (Microsoft Research), Nicholas Kirsch (UNH) and Tom Miller (UNH). Thanks to all for serving!

Pervasive computing problems and ideas are often introduced using videos. An excellent exampe is the Microsoft Health Future Vision video (download, watch on YouTube). 

Let’s focus on three themes from the video that are relevant to the senior projects: interactions with multi-touch interfaces, interactions with tangible user interfaces, and data manipulation/fusion. Multi-touch surfaces appear throughout the video: in Sabine’s home, in the doctor’s office, and in the hospital lobby. Several of the multi-touch interfaces, such as Sabine’s remote control, and her virtual wallet (used in the lobby), are tangible interfaces. Finally, Dr. Kemp manipulates/fuses data when interacting with Alex (patient in bed) and especially during the meeting with Sabine and Wei Yu.

The two senior projects will leverage Project54′s Microsoft Surface multi-touch table. Here is a video by UNH ECE graduate student Tim April introducing some of the interactions he has explored with the Surface.

With all this in mind, here are the specifics on the two proposed projects.

Project 1: Mobile data fusion

This project will explore fusing data, such as images, video, sounds and outputs from various sensors (temperature, pressure, accelerometers, etc.). Data fusion will require some simple processing, such as setting beginning and end points for sounds, zooming images, etc. It will also require more complex digital signal processing of data, e.g. windowing and filtering (topics covered in ECE 714). Consequently, work on this project will focus on data processing as well as object-oriented programming that is necessary to control the multi-touch table.

This project will be tied to a collaborative effort with WPI on creating a fleet of UAVs. Thus, eventually, the data to process and display on the multi-touch will come from the UAVs. However, as a first step, data will be generated through games, similarly to work done by Jatin Matani and Trupti Telang.

Project 2: IR wallet

The Microsoft Surface uses infrared illumination and cameras to recognize interactions with its surface. It can also recognize 2D barcodes if they are visible in the IR part of the spectrum. The “IR wallet” project would result in a tangible user interface, similar to Sabine’s virtual wallet, that can display 2D barcodes in IR. These in turn will be picked up by the Microsoft Surface. Work on this project will focus on microcontroller-based design (e.g. with an Arduino board) and object-oriented programming for the Surface.

Bryan spent time in the Project54 lab discussing various aspects of driving simulator and field studies. He then gave a thought-provoking talk reviewing results from multiple studies exploring driver workload and distraction. I expecially enjoyed his discussion of physiological measures that can be used to estimate workload. E.g. Bryan has found that heart rate is a robust estimate of workload and is often more useful than the often-used measure of heart rate variability. Bryan also discussed work on validating driving simulator results through field studies. His data indicate that driving simulator results can be used to predict relative changes in workload measures under different situations in real-life driving. However, the actual values of the measures collected in simulator and field studies often differ significantly.

My favorite part of the information session was the student panel. Bob Henry invited five students who spent time abroad (three in Budapest and two at Heriot-Watt University in Scotland) last fall to answer questions from the audience. As in panels I’ve seen in the past, the students gave the exchange programs glowing recommendations.  However, this year Bob Henry added something I haven’t seen in the past: the parents of a student panelist were on hand to answer questions from their perspective. This strikes me as an excellent way to make the parents of prospective study-abroad students feel comfortable with the program, and prepare them for the inevitable stress of their children moving to another continent for a few months.

Several UNH ECE students were at the information session and I hope they take advantage of the opportunity to study in Budapest. Carol Perkins and four other ECE juniors are currently in Budapest and, according to Carol, they are adjusting very well.

Nick joined UNH ECE in the fall of 2010. His interest is in spectrally efficient wireless communications systems utilizing software defined radios. Tom and I have been involved with the Project54 system since 1999. Tom’s interest is in embedded system design and application development and on human-computer interaction with mobile devices. My primary interest is in human-computer interaction for mobile devices and for desktop multi-touch devices.

The Project54 lab was created in 1999 in partnership with the New Hampshire Department of Safety to improve technology for New Hampshire law enforcement. Project54’s in-car system integrates electronic devices in police cruisers into a single voice-activated system. Project54 also integrates cruisers into agency-wide communication networks. The Project54 system has been deployed in over 1000 vehicles in New Hampshire in over 180 state and local law enforcement agencies.

Research focus

Both the PhD and the MS student will focus on the relationship between various in-car user interface characteristics and the cognitive load of interacting with these interfaces, with the goal of designing interfaces that do not significantly increase driver workload. Work will involve developing techniques to estimate cognitive load using performance measures (such as the variance of lane position), physiological measures (such as changes in pupil diameter) and subjective measures (such as the NASA-TLX questionnaire).

The work will utilize experiments in Project54’s world-class driving simulator laboratory which is equipped with two research driving simulators, three eye trackers and a physiological data logger. Laboratory experiments will be complemented by field deployments in law enforcement agencies such as the New Hampshire State Police, which operates over 300 police cruisers. Project54 has deployed a state-wide data update infrastructure for the New Hampshire State Police which allows remote updates to in-car experimental software and remote collection of experimental data.

 Appointment

The PhD student will be appointed for four years, and the MS student for two years. Initial appointments will be for one year, starting between June and September 2011. Continuation of funding will be dependent on satisfactory performance. Appointments will be a combination of research and teaching assistantships. Compensation will include tuition, fees, health insurance and academic year and summer stipend.

How to apply

Starting with the 2009-2010 academic year the primary aim of the course has become to introduce graduate students to the general tools of scientific research. I championed this new aim for the course and I’m grateful that my faculty colleagues gave me an opportunity to share my excitement about scientific research with our graduate students. 

The course had three main aspects: 

• Lectures on performing scientific research. My lectures introduced students to the steps of scientific research, from formulating problems, to proposing hypotheses and conducting experiments.
• Research talks. Each student attended at least 15 talks. Most of these were held at UNH and the speakers were exceptional. At the same time, I encouraged the students to recommend talks that we can attend at other institutions. The result: trips to MIT, BU and WPI.
• Research proposal. At the end of the two semester sequence each student submitted a short research proposal and gave a presentation on the same. The proposals were developed over the two semesters, with students working individually and in groups. I provided feedback throughout the year on different segments of the proposal. 

In an informal survey at the end of the academic year most students indicated that they liked the new version of the ECE Graduate Seminar and that they thought it was useful. All of the students thought that learning about the tools of science is useful and the majority also indicated that their technical writing skills improved due to this course. These responses are certainly encouraging. 

I will be teaching ECE 900 again during the 2010-2011 academic year. Based on my experiences reported here, as well as those with my Fundamentals of Ubicomp course, I plan to implement two changes: 

• Accelerate proposal development. I will move up the due date for the final research proposal to sometime early in the second semester. The accelerated schedule should help build excitement for learning about science. It will also give us time at the end of the year to discuss how other researchers approach scientific work. Finally, it will help with student participation in the course, which is the subject of the second change I intend to implement.
• Increase student participation. While I encouraged student participation throughout the semester, the results were not always stellar. By accelerating the proposal development process I hope to provide students with discussion topics that they feel comfortable talking about. I also intend to ask students to hold multiple formal presentations in class. One assignment that students can expect next semester: create a 15 minute presentation about a research topic of your choice, based on a research video posted online.

In this course I used the excellent new ubicomp textbook [1] edited by John Krumm. I highly recommend this book to anyone starting out in the field of ubicomp. Specifically, I like two aspects of the book. First, the team of contributors assembled by John provides a comprehensive introduction to the myriad topics that make up the ubicomp field. The fact that ubicomp is an interdisciplinary field is exciting, but getting an overview of the field may seem like a daunting task. The textbook provides this overview. Second, paraphrasing Aaron Quigley‘s assessment of his chapter [2], the book provides “an entry point” to the world of conducting research in general, and ubicomp research in particular. The contributors discuss the tools used in various aspects of ubicomp research, from prototyping, to user studies, to data processing. The individual chapters help the reader formulate research questions and steps, and provide valuable tips on how to report on results. 

The course covered three topic areas:

• History of ubicomp. The semester started with Weiser’s seminal paper [3] and with a textbook chapter introducing ubicomp by Roy Want, one of Weiser’s collaborators at Xerox PARC.
• Building ubicomp systems. We discussed various aspects of creating ubicomp systems, from writing always-on software, to privacy, to conducting laboratory and field experiments.
• The user experience. As this is my research focus, we spent a considerable amount of time discussion user interactions with ubicomp systems, from speech interactions, to multi-touch tables, to tangible user interfaces.

I found that an excellent way to discuss ubicomp topics is to take advantage of research videos posted online. We viewed many such videos and this led to productive discussions. We also benefited from excellent talks by Marko Popovic, Bret Harsham and Albrecht Schmidt.

I felt that the course was a success. Students indicated that they liked the course and thought that it was useful. The course also allowed students to express themselves creatively through the course project. The results were impressive and I’ll end this post with an example. The video below is the work of UNH ECE seniors Amy Schwarzenberg and Kyle Maroney (both graduated in May). Amy and Kyle explored user interactions with a Microsoft Surface multi-touch table.
