Prof. Camille Peres and Prof. Farzan Sasangohar invited Prof. Nancy Cooke to visit Taxes A & M university on May 8th and 9th. Mustafa Demir (postdoc), Chris Lieber (graduate student), and I were fortunate to get to travel with Nancy. Camille and Farzan arranged a wonderful trip itinerary for us for two full days of events. The tornado just made the whole trip an unforgettable adventure.

I will be an Assistant Research Scientist at Arizona State University starting in September 2018, in the Center for Humans, Artificial Intelligence, and Robot teaming, affiliated with the office of Global Security Initiative. I will work with Drs. Nancy Cooke and Spring Berman. My primary roles will be writing research grants and conducting experiments on the research platforms with human subjects. It is an interdisciplinary team and bears many great opportunities for human factors and human-robot interaction research.
I have stayed in Raleigh/Durham, North Carolina for 7 years and this has become my second hometown. Thanks to my host family, friends, colleagues, and professors for all the support and care along my journey.
The Pedestrian App experiment is finished, and our team celebrated at the Duke University Commons, right next to the Duke Chapel. It was the most challenging research project that I have ever conducted as of this point of my life. When I have time, I will write more about the journey.
The experiment was conducted at the North Carolina Center for Automotive Research NCCAR (NCCAR) in Garysburg, NC, two hours away from Duke University. This professional race track facility enables us to control the traffic conditions without any random passing cars or pedestrians. To use this facility, we had to work with the availability of the track. Our data collection team had 8 people and all need to be available the whole time. We also need to check the availability of participants. It was not worth the cost to make the trip with less than three participants signing up for each day. We cannot collect data when the weather was rainy or two windy.
Because the experiment site was so far away from our lab, we first tried to recruit participants from the local community by sending hundreds of recruitment letters to nearby organizations, including churches, grocery stores, police department, fire department, community colleges, etc. However, we had a very low response from people. With the permission from Walmart managers, our team spent two evenings talking to random customers about our research inside the store and at the entrance of the store. We had some luck getting people from Walmart, but that was still not enough.
Then we were suggested to recruit participants from Duke University. Due to the long distance, we offered rides to participants. They had to leave with us at 7 am or 8 am in the morning and return around 7 pm in the evening. The compensation was $25. We had to have at least three participants on one day to make the trip. We asked our friends to spread the word. Surprisingly, we got some participants from NC State and UNC Chapel Hill. In other words, the project involved three universities, with participants from four distant cities with a relatively low compensation.
On the night before the last day of data collection, we had great difficulty finding the third participant to make the trip the next day. I had to make a decision whether to cancel the trip and reschedule the two people who has already signed up. Right before we gave up, someone agreed to go. On the next morning, when I was driving to the experiment site, another driver called me that one of the students changed his mind and did not want to go that morning, meaning we would need to make one more trip to just collect data for one extra person. Luckily, the director of NCCAR, Sam, helped us find another person to make up the vacancy so that we finished the data collection that day.
Other incidents and difficulties also happened during the experiment.
What a great memory!

Big conferences between 2012 and 2017 that I still remember:
On my way back from lunch, I walked through the Department of Computer Science at Duke and saw this wall of mailbox. Unlike metal or plastic doors at any resident housing I had seen before, these mailbox have transparent glass doors, so that you can easily tell whether there is anything in your mailbox without opening it. What a clever design! The lock at each glassdoor also gives users an option whether to lock it.
From Dr. George Gopen's one-day writing workshop, I learned amazing psychology of readers. More specifically, readers process information in a certain way when reading scientific work, and therefore, if we write as they expect, we can make a strong case, and it is easier for readers to read. For each sentence, we should be clear about the subject of the sentence, keep the verb close to the subject, provide a link to the old information, and stress new important information in the end of a sentence. The structure is fixed, but the substance for positions in the structure can be moved and has to be decided by the writer. The decision of the flow and what to stress makes each individual's work unique. The message seems so simple, but overcoming unconscious bad writing habit and practicing this principle takes a long way.
Together with a few other authors' helpful writing books, this workshop enhanced my belief that scientific writing skill can be trained. It is a pleasure to make sense of things and make one step closer to good communication. Thank you, Dr. Gopen.
From Feb 8 to April 10, I had an unexpected leave from my work at Duke due to my visa issue. This misfortune turned into blessings in many ways.
First, my audit student Sarah Park, also our Engineering Librarian, stepped up to help me lead the seminar, Trust in Autonomy, so that my students did not have to drop the class at the point of passing the drop deadline.
Second, many friends came to help me pack my belongings so that I was able to get everything ready to leave in about one week. In case I were not able to come back when my apartment lease were due in the end of May, one friend offered to store my belongs in her garage.
Third, I got the opportunity to celebrate Chinese New Year on Feb 16 with my family in China for the first time in the past 10 years. Chinese New Year (using the lunar calendar) is always during the Spring semester in the US, so I was not able to go home ever since I came to the US in 2007. I wished that I had spent more time with my new nephew and niece, and then my dream came true in this interesting way.
Fourth, my high school classmate, Dr. Zhu, found me at my hometown, Wenzhou, and invited me to help him with his Child-Robot Interaction project to educate k-12 children with artificial intelligence. His new company has a 30-year mother company, Yalong, famous in producing vocational robotics training equipment in China. Below is the video intro of the company.
Fifth, when I was in China, I was able to submit my long-waited journal paper based on my dissertation to the International Journal of Social Robotics.
Sixth, I also got several job interviews and two job offers during my leave. When I finish my postdoctoral position at Duke University, I will have a place to go for my next step.
There are many more blessings in my life in the midst of my big trouble. I am just grateful that life is still full of faith, hope, and love.
Jan 25-26, 2018 Center for Innovative Research in Cyberlearning (CIRCL) Workshop on Robots Young Children and Alternative Input Methods
It was an honor and great experience working with Prof. Yanghee Kim to co-organize the child-robot interaction workshop at Northern Illinois University. The presenters were big experts in child-robot interaction research areas, such as speech recognition, image processing, human-robot interaction design, and learning theories. I learned a lot from all of them and especially liked Prof. Cynthia Breazeal's personalized robot design. In the near future, I would like to test out a few ideas about personalized robot design.
My impression of Alexa is better than this, but it is still a fun video to watch because it reflects the current speech recognition and natural language processing issues in artificial intelligence. And HAL 9000 (2001: A Space Odyssey shot by Stanley Kubrick in 1968) is always a classic movie to ruminate on.
Victoria Nneji, a colleague of mine, mentioned to me the Grand Challenges for Engineering in the 21st century, and which I found very interesting. These challenges are not only talking about what changes we can make, but also about what need to be changed. I like the challenge of JOY OF LIVING and propose to scale up customization using Human Factors methods. I study what factors influence people's intrinsic motivation in interacting with robots, their emotional attachment to the robots, and how we can design the robots accordingly. The findings will generalize to different entities in people's ordinary life.
"From urban centers to remote corners of Earth, the depths of the oceans to space, humanity has always sought to transcend barriers, overcome challenges, and create opportunities that improve life in our part of the universe. In the last century alone, many GREAT ENGINEERING ACHIEVEMENTS became so commonplace that we now take them mostly for granted. Technology allows an abundant supply of food and safe drinking water for much of the world. We rely on electricity for many of our daily activities. We can travel the globe with relative ease, and bring goods and services wherever they are needed. Growing computer and communications technologies are opening up vast stores of knowledge and entertainment. As remarkable as these engineering achievements are, certainly just as many more great challenges and opportunities remain to be realized. While some seem clear, many others are indistinct and many more surely lie beyond most of our imaginations.
