Person profile

I am broadly interested in experimental systems research in the field of mobile computing. My research interests have spanned from energy-efficient mobile computing, to edge computing, to mobile crowdsensing and to augmented/virtual reality. My research often takes the approach of building potentially large-scale prototype systems and then evaluating them experimentally.

My current work contains two parts. One is creating innovative mobile applications to solve real life problems, such as crowdsourced indoor mapping and AR-based assistance for mechanical assembly and maintenance. The other part of my research focuses on solving the performance, energy-efficiency and scalability challenges that the new applications (e.g. video crowdsourcing, autonomous driving) pose to the cloud and network architectures.

Since I have stopped updating this page, you can find the latest information about my research from my group's website.

Software

1. Crowdsourced Indoor Mapping, Localization and Navigation

A demo video of our image-based indoor mapping, localization and navigation system is now available on YouTube. Link

Our system builds 3D models of indoor environment from unordered 2D images using Structure-from-Motion(SfM) techniques, detects pedestrian paths from smartphone sensor data, and extracts place information from images. Our system includes an Android client and an app server. With the client, users can locate themselves by taking photos from where they are, can search for places by descriptions or images, and can be guided to destinations with textual and visual information.

2. Gigasight: Crowdsourcing of videos from mobile devices (source code is available on GitHub)

I participated the design and development of Gigasight during my research visit to Carnegie Mellon University in year 2012. This work was published in Mobisys 2013.

3. Integration of pervasive public display networks and distributed cloudlet infrastructure

It is a joint work with Lancaster University during my research visit to Carnegie Mellon University in year 2013.

Key techniques: Qemu/KVM, Internet suspend/resume, Node.js + MySql

4. Tools for energy-efficiency analysis

SmartDiet is a proof-of-concept toolkit for analyzing energy usage of Android applications and identifying constraints regarding mobile code offloading. It was mostly written by Aki Saarinen and the source code is available on GitHub. We made a demo of SmartDiet at Sigcomm 2012. The demo description can be found from here.

Software

1. Crowdsourced Indoor Mapping, Localization and Navigation

A demo video of our image-based indoor mapping, localization and navigation system is now available on YouTube. Link

Our system builds 3D models of indoor environment from unordered 2D images using Structure-from-Motion(SfM) techniques, detects pedestrian paths from smartphone sensor data, and extracts place information from images. Our system includes an Android client and an app server. With the client, users can locate themselves by taking photos from where they are, can search for places by descriptions or images, and can be guided to destinations with textual and visual information.

2. Gigasight: Crowdsourcing of videos from mobile devices (source code is available on GitHub)

I participated the design and development of Gigasight during my research visit to Carnegie Mellon University in year 2012. This work was published in Mobisys 2013.

3. Integration of pervasive public display networks and distributed cloudlet infrastructure

It is a joint work with Lancaster University during my research visit to Carnegie Mellon University in year 2013.

Key techniques: Qemu/KVM, Internet suspend/resume, Node.js + MySql

4. Tools for energy-efficiency analysis

SmartDiet is a proof-of-concept toolkit for analyzing energy usage of Android applications and identifying constraints regarding mobile code offloading. It was mostly written by Aki Saarinen and the source code is available on GitHub. We made a demo of SmartDiet at Sigcomm 2012. The demo description can be found from here.
