Abstract:
A central question in mobile computing
is how do you test mobile applications, that depend on real context, in real
environments with real users? User studies done in lab environments are
frequently insufficient to understand the real-world interactions between user
context, environmental factors, application behaviour, and performance results.
I will introduce LiveLabs, a 5 year project that started at the Singapore
Management University in early 2012. The goal of LiveLabs is to convert four
real environments, the entire Singapore Management University campus, a popular
resort island, a large airport, and a popular shopping mall, into living
testbeds where we instrument both the environment and the cell phones of
opted-in participants (drawn from the student population and members of the
public). We can then provide 3rd party companies, and researchers the
opportunity to test their mobile applications and scenarios on the opted-in
participants — on their real phones in the four real environments described above.
LiveLabs will provide the software necessary to collect network statistics and
any necessary context information. In addition, LiveLabs will provide software
and mechanisms to ensure that privacy, proper participant selection, resource
management, and experimental results and data are maintained and provided on a
need-to-know basis to the appropriate parties.
I will describe the
broad LiveLabs vision and identify the key research challenges and
opportunities. In particular, I will highlight our current insights into indoor
location tracking, dynamic group and queue detection, and energy aware context
sensing for mobile phones. I will also share our current status (we have gone
live at our university campus) and some of the non-obvious challenges that
arise from deploying these systems in real environments.
Biography:
Rajesh Krishna Balan is an associate
professor at Singapore Management University’s School of Information Systems.
He received his Ph.D. in computer science from Carnegie Mellon University and
has over 15 years of research experience in the broad area of mobile systems
and software. Some of the diverse areas that he has worked on include
infrastructure support for multiplayer mobile games, improvements to public
transportation networks, understanding and improving the software development
process in outsourced environments, and developing and testing novel
retail-focused mobile applications. More details about him can be found at http://apollo.smu.edu.sg/.
Rajesh is also a director of the new
LiveLabs Urban LifeStyle Innovation Platform. The goal of this platform is to
allow mobile applications and services to be tested with real users on real
phones in real-world environments. Currently, LiveLabs has been deployed at a
university campus with further deployments at an airport, a resort island, and
a large mall planned for the near future. More details about LiveLabs can be
