Research

Two most recent or ongoing projects:

1) LOCO (2010-2014), in which we focus on hyperlocal content production by citizen photojournalists and reader reporters for a hyperlocal news provider (Sanoma News) as well  as study the user experience of mobile news sites on tablets (Keski-Pohjanmaan Kirjapaino). This research is part of Next Media SHOK programme by TIVIT and funded by TEKES.

2) UXUS (2011-2015), which focuses on "User experience and usability in complex systems" in metals and engineering industry. UXUS SHOK programme by FIMECC is funded by TEKES.

Under preparation

3) Data4Value - use of IoT data for company's R&D and service development activities.



Next Media - LOCO: Hyperlocal Content Production and Community Management

We are currently involved in the Next Media programme in two workpackages.

In WP1 - eReading we study user experience of mobile news sites on tablets as well as user experience related to authentication and payment.

In WP3 the research is related to hyperlocal news content production and community management.  We study the UGC productionfrom the point of view of citizen photojournalists and reader reporters.

This work is done in close collaboration with Sanoma News  and Aalto Media Factory. During the first year of the Next Media programme we also had close collaboration with Tampere Research Centre for Journalism, Media and Communication (COMET) and Helsinki Metropolia University of Applied Sciences.

In 2013 we also cover themes related to eReading in collaboration with several news publishers as well as VTT and Helsinki Metropolia University of Applied Sciences.

Our research topics include
  • participation motivations
  • user experience
  • new crowdsourcing based content production processes, e.g.
    • mobile tasks (assignments)
    • privacy issues in location-based crowdsourcing
  • quality attributes of high quality UGC and methods to support and guide to high quality contributions
  • user experience of authentication and reading of news on mobile tablets

UXUS - User experience and usability in complex systems

We study user experience and usability in real-life contexts of using complex systems in metal and engineering industry (MEI).

Our research focuses on:
  • the quality of experience and factors contributing to user experience in using the complex systems (e.g. a longitudinal study of an FMS system)
  • supporting user activity and user experience with novel interaction techniques and
  • understanding the context dimensions and factors affecting user experience in the cases.

Mobile news journalism (PALTI, MOJODIPx2, PhD Thesis work)

I had a great opportunity to be the project manager for PALTI project (2007-2009) which was funded by Finnish Ministry of Education.

Through my previous colleagues at NRC, I bumped into a really interesting topic of mobile news journalism as the main theme of this project and accompanying MOJODIP projects.

We carried out several studies on using smartphones in news content creation and delivery, as well as looked at new mobile working processes. This completely took my PhD thesis work to this track. LOCO project presented earlier on this page is a natural continuation to this work.

We have two mobile news journalism related M.Sc. theses from PALTI and MOJODIP and a number of peer-reviewed academic publications. In addition, the findings have been used in practical development work.

More details on the PALTI project are presented in the following page
