2nd Call for Papers
---------------------------------------------------------------------
3rd Workshop on Research in the Large – App Stores, Wide Distribution, 
and Big Data in MobileHCI Research

at MobileHCI 2012, San Francisco, California

Deadline: May 25th, 2012
Workshop: September 21st, 2012

http://large.mobilelifecentre.org
---------------------------------------------------------------------

Theme
------
Traditionally, mobile HCI studies have often been conducted in highly 
controlled environments, involving small numbers of users. App stores 
and other wide distribution channels have now provided researchers with 
a enormous opportunity to move outside the lab. Indeed, many researchers 
have started to use public deployments and big data for mobile HCI 
research. Publishing apps in mobile application stores and public APIs 
for mobile services enable researchers to study large samples in their 
‘natural habitat’ – but this also requires adaptation of evaluation and 
research methods, and dealing with deployment issues previously 
unencountered by most MobileHCI researchers.

This workshop continues the ‘Research in the Large’ workshop series held 
at UbiComp 2010 and 2011. Relevant topics include the design of 
large-scale studies, reaching target users, dealing with new types of 
evaluation data, and heterogeneous usage contexts. We seek ways to 
systematically collect, analyse and make sense of large datasets, 
potentially in real-time.

The goal of this workshop is to provide a forum for researchers and 
developers from academia and industry to exchange experiences, insights 
and strategies for wide distribution of research apps and the resulting 
large data streams these deployments produce. We aim at building an 
understanding of the opportunity of the different channels and the 
issues and obstacles involved in a research context.

Topics
------
We welcome participants from both industry and academia who have an 
interest and/or experience in the following themes:
- Methods & experiences with research through app stores and other 
distribution platforms
- Strategies for attracting and recruiting a suitable sample
- Dealing with big data: infrastructure, tools and experiences in 
dealing with large- scale datasets, potentially those growing by 
millions of data points every day
- Statistical & visual analysis methods and tools for the various sorts 
of data resulting from public apps
- New developments of distribution channels, tools and infrastructures, 
and their potential effects
- Dealing with uncertainty and data noise
- Identifying interesting usage and experience patterns for further research
- Combination of large-scale studies with smaller studies
- Re-integration of research in the large outcomes in the design & 
development process of apps
- Design of appropriate large-scale studies based on given research 
questions
- Approaches to increase internal and external validity

Submission
------
Prospective authors are invited to submit their contribution, in PDF 
format conform to the ACM Mobile HCI 2012 archive format electronically 
via EasyChair no later than May 25th, 2012. Submissions are expected to 
be either up to 4 pages describing research that addresses one or more 
of the workshop’s themes or up to 2 pages position papers on the 
opportunities and challenges ahead. Papers must be anonymized and will 
be reviewed by a program committee from industry and academia.

The program committee will nominate a best paper, which will be included 
in a special issue of the International Journal of Mobile Human Computer 
Interaction (IJMHCI).

Important Dates
------
* Friday May 25, 2012 – Submission Deadline
* Friday June 29, 2012 – Acceptance Notification
* Monday July 23, 2012 – Revised Manuscript Due
* Friday September 21, 2012 – Workshop in San Francisco!
