It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

The user-centered design (UCD) process in HCI has recently been criticized for not delivering breakthrough innovations in technology. In this paper we consider this critique through a literature review and two case studies of innovation. Our conclusions suggest that there is nothing wrong with the attitude of user-centered design which has probably been present in all major innovations down the centuries. Rather, the practice of UCD in HCI lacks attention to business factors and long term uptake of technology in society. This compromises its impact on products and should be incorporated into the study of HCI itself.

Lehtinen, Vilma, Näsänen, Jaana and Sarvas, Risto (2009): "A little silly and empty-headed": older adults' understandings of social networking sites. In: Proceedings of the HCI09 Conference on People and Computers XXIII 2009. pp. 45-54.
This study suggests reasons for the absence of a growing proportion of the population, the so-called baby boomers, from the otherwise highly popular social networking sites. We explore how people of this age group understand social networking sites and how these understandings fit certain aspects of their life. Designing social networking sites that match older adults' life would increase their possibilities of coping with the changes related to their age and of contributing to the information society. In a qualitative study involving use of an existing social networking site, and group and personal interviews, we found that understanding the internet as a dangerous place, and social networking sites as places of socially unacceptable behavior, hinders the use of these technologies. To include older adults, we propose arrangement of social events for getting familiarized with these services and offering of clear and simple privacy management on the sites. These actions have implications for users of all ages.

Lehmuskallio, Asko and Sarvas, Risto (2008): Snapshot video: everyday photographers taking short video-clips. In: Proceedings of the Fifth Nordic Conference on Human-Computer Interaction 2008. pp. 257-265.
Camera phones and consumer digital cameras number hundreds of millions worldwide and most of them have the ability to take video in addition to photographs. Public discussions, marketing, and academic research often emphasize the new and innovative ways in which people use their ubiquitous digital cameras, especially camera phones, in combination with the Internet. In this paper we present our qualitative study of 13 people and their picture taking habits with regular cameras and camera phones. We focus on their videography practices in the context of their general use of photo and video media. Our results contradict the general assumption that the availability of ubiquitous video technology has significantly changed people's practices in home-mode pictorial communication. The models for capturing videos are often taken from situations in which previously taking snapshot photographs was the only option. Therefore, we suggest that mobile media creation and sharing technology has only gradually changed people's snapshot photography and videography practices.

Interesting characteristics of large-scale events are their spatial distribution, their extended duration over days, and the fact that they are set apart from daily life. The increasing pervasiveness of computational media encourages us to investigate such unexplored domains, especially when thinking of applications for spectator groups. Here we report of a field study on two groups of rally spectators who were equipped with multimedia phones, and we present a novel mobile group media application called mGroup that supports groups in creating and sharing experiences. Particularly, we look at the possibilities of and boundary conditions for computer applications posed by our findings on group identity and formation, group awareness and coordination, the meaningful construction of an event experience and its grounding in the event context, the shared context and discourses, protagonism and active spectatorship. Moreover, we aim at providing a new perspective on spectatorship at large scale events, which can make research and development more aware of the socio-cultural dimension.

Camera phones have been viewed simplistically as digital cameras with poor picture quality while neglecting the utility of the two key functionalities of mobile phones: network connection and access to personal information. This is the first HCI paper to examine mobile photos from a systemic perspective: how assignment of phases of mobile photo lifecycle to different platforms affects social discourse around shared photos. We conducted a 6-week user trial of MobShare, a tripartite system with dedicated functions and task couplings for a mobile phone, a server, and a PC browser. We analyze how MobShare's couplings and distribution of functionalities affected the observed types of social discourse that formed around mobile photos: in-group post-event discourse, self-documents and reports, greetings and thanks. Several central design issues arising from the systemic view are discussed: heterogeneity of environments, integration and distribution of functionalities, couplings and decouplings of interaction tasks, notification mechanisms, and provision of necessary UI resources for different tasks.
