NordiCHI 2012

NordiCHI is the bi-annual Nordic Conference Human-Computer Interaction. Though a country from Scandinavia traditionally hosts it, the conference attracts designers and researchers from all over the world. This year, 2012, it took place at the ITU University of Copenhagen, Denmark.

My colleague Heiko and I found this year’s NordiCHI to be an excellent forum for exchanging ideas in a super-friendly environment. We received plenty of valuable feedback for our ongoing research on using ambient light to remind office worker about upcoming tasks. In addition, there were plenty of interesting talks in up to four parallel sessions.


Edward Cutrell et al. investigated the question of “how bad is good enough?” with respect to the quality of mobile videos. This work addresses the problem of mobile video consumption in areas where data connection is highly expensive. They therefore explored, which level of quality is still acceptable for low-income mobile-phone users in urban India. The results provide evidence that these people will accept a significant loss of quality in order to save money.

Interesting insights were that in these areas of the world, people need to “count” their bytes, which is hardly supported by today’s phones and applications. Also, Ed Cutrell suggested that the acceptance of low-quality videos depends on the user expectance. This may be relevant in developed countries, too, e.g. when people try to go online in mass events.

Charlotte Magnusson et al. presented Context Cards, a novel, light-weight way of raising developer’s awareness about different contexts in which mobile applications can be used. Each card shows a different setting, such as a young mother with a kid on one hand, the phone in the other, while pushing a baby buggy. They distributed the Context Cards at the Mobile World Congress, the “world’s premier mobile industry event” and received very positive feedback from attendees. Context Cards are free to use and can be accessed in printable form from here.

Thomas Visser, in his talk “I Heard You Were on Facebook” explored the creation of awareness systems, i.e. systems that provide a subtle sense of what is going on in one’s social network. They developed an awareness system that allows recording short sound bites from daily life and share them via Facebook. On the basis of a study with three groups of four persons each, they conclude that sharing sound bites increases the perceived social awareness of the group members.

Ole Sejer Iversen et al. presented insights from participatory design with mentally disabled users, which was done for a local art museum. They pointed out that we cannot just bring our set of values to the table but values emerge and require mediating in participatory design with diverse user groups.
