Two Demos To Be Showcased at ACM SenSys’19

Two demos were accepted for presentation at ACM SenSys’19 in New York City, NY, in November 2019.

A demo led by Joseph DeChicchis, titled Adaptive AR Visual Output Security Using Reinforcement Learning Trained Policies, demonstrates how reinforcement learning-based policies for hologram positioning perform on Magic Leap One augmented reality sets. This demo builds on the work on learning for hologram positioning in AR led by Surin Ahn, previously evaluated via simulations alone. Related work:

Additionally, a demo led by Jovan Stojkovic, Zida Liu, and Guohao Lan, titled Edge Assisted Collaborative Image Recognition for Augmented Reality, presents a dynamic approach for handling heterogeneous multi-user visual inputs for image recognition in augmented reality, demonstrated on an edge-assisted Google ARCore platform.

Summer Research Experience for Undergraduates Students Presenting Their Work on Edge Computing and Augmented Reality

Two summer Research Experiences for Undergraduates students have presented their summer projects at the Duke University REU showcase.

Courtney Johnson presenting his summer research on precision eye tracking for Magic Leap performance and user experience optimization.

Jovan Stojkovic, Duke ECE REU Fellow and a rising senior at the University of Belgrade, presented his poster titled Edge Computing Platform for Collaborative Augmented Reality. Over the summer, Jovan has built a platform that allows multiple users’ related images, captured with Android phones running Google ARCore, to be processed jointly on an edge server, improving user’s quality of object recognition.

Courtney Johnson, Grand Challenges in Engineering NSF REU Fellow at the Pratt School of Engineering and a rising junior at North Carolina A&T State University, presented his poster titled Intelligent Augmented Reality Adaptation to Users’ Eyes. Over the summer, Courtney has been exploring a range of uses of precision eye tracking, available in modern augmented reality headsets, to optimize the performance of augmented reality systems.

Both Jovan’s and Courtney’s research results will be integrated into paper submissions later this year.

Undergraduate Students Presenting Their Work on Next-generation Augmented Reality at Duke University Undergraduate Research Showcases

Three undergraduate students have presented the results of their independent studies in CS and ECE poster sessions and demonstrations here at Duke University.

Michael Glushakov presented a poster and a demo of his work on edge computing-supported augmented reality with Google ARCore, demonstrating how edge computing can be used to enable persistent and personalized augmented reality experiences, and developing a portal that allows people without coding background to create personalized AR experiences. Joseph DeChicchis presented a poster and a demo of his work on using reinforcement learning to teach holograms to move out of the way of real-world objects. Joseph’s demonstration showcased this capability on Magic Leap One devices. Madeline Wilkinson presented a poster of her work on using eye tracking to personalize user experiences in augmented reality on Magic Leap One devices.

Michael Glushakov presenting his work on edge-enhanced ARCore experiences.

Academic Job Market: One Experience

This post is intended as a “sample point”, and a bit of informal guidance, for people who are on the academic job market, or will be going on it soon. Throughout the different phases of the job market, I’ve relied on the experiences of many people who took the time to describe their experiences. Paying it forward, now, by describing my own.  

My application materials, as a reference:

I am writing this post just as my first semester as an Assistant Professor of Electrical and Computer Engineering at Duke University is about to start. My office and my lab are freshly remodeled, and I’ve had fun getting the lab equipped. My graduate seminar class starts on Monday. It is all so exciting.

Getting here required surmounting the challenges of the academic job market. I would not call it the hardest thing I’ve ever done — getting the PhD, for me, was harder, for example. However, the job market months were the most intense of my life. Take your most challenging paper deadline experience, multiply it by ~ 30, and stretch it out to several months — that is roughly the level of intensity of the experience. If you are going on the job market soon, buckle up! It will be one exciting, wild ride.

Below, first, advice to folks on the job market, then my experience in numbers, dates, and pictures.  Continue reading

Academic Job Market in 13 Hotel Room Views

I took pictures of the views from all but one of the hotel rooms I’ve stayed in, during my interviews, February-April of this year. Gorgeous continent’s urban and not-so-urban areas. Nights and days, storms and clear days, sunrises and sunsets. Some on-campus hotels, and some close-to-campus. Job market is a blur of these experiences.

February:

Running collection, June 2018

Over the last six months, several true gems have been added to the “collection” of the states where I ran at least one mile:

  • Dec. 2017: Utah.
  • Feb. 2018: Wisconsin.
  • March 2018: Minnesota.
  • June 2018, on a lovely road trip: North Dakota, South Dakota, Montana, and Wyoming.

The map is starting to look full. 39 states ran; only 11 states left. States where I ran at least one mile, marked in blue:

2017 IEEE Fog World Congress

IEEE Fog World Congress was a blast. It takes a lot to put together an inaugural conference on a new topic — the organizing committee did a great job putting the event together.

Moderating the Fog and Edge from the Practitioners’ Perspective panel.

I served on the TPC of the Research Track of the conference, and also ended up contributing to 4 different sessions during the conference itself:  Continue reading

Running collection, November 2017

This year I have been fortunate to be able to add 4 new states to the collection of the states where I ran at least a mile: Georgia, Nebraska, Iowa, and Indiana. With the addition of Sweden and Denmark to the collection of countries I went running, this brings the totals to:

  • US States: 33 out of 50.
  • Countries: 14 out of 196.

States where I ran at least one mile.
