This paper echoes and points to work we have presented elsewhere on establishing the links between issues of sustainability and interaction design. The significant contribution of this paper is a description of the use of design critique as a research method and an argument for its importance to HCI researchers, especially with respect to very complex design contexts—the link between sustainabi...

Linear stability analysis indicates that solar core is thermally stable for infinitesimal internal perturbations. For the first time, thermal metastabilities are found in the solar core when outer perturbations with significant amplitude are present. The obtained results show that hot bubbles generated by outer perturbations may travel a significant distance in the body of the Sun. These deep-o...

The purpose of this paper is to offer a reflection on some of the challenges of teaching interaction design. A proposed solution to address these challenges is through a businessdriven problem which has been translated into a research question to be tackled by students in their learning context. The case study outlines and evaluates the six stages of this process. Apart from providing the compa...

Our work focuses on the use of formal techniques in order to increase the quality of HCI software and of all the processes resulting from the development, verification, design and validation activities. This paper shows how the B formal technique can be used for user tasks modelling and validation. A trace based semantics is used to describe either the HCI or the user tasks. Each task is modell...

representations were depictions of selftracking data where the relationship between the data and its representation were not obvious to the viewer. As illustrated in the findings, these representations took inspiration from the visual arts. They were forms of self-expression, as illustrated in Tomasz’ visualisation of skateboarding. Furthermore, these representations were made deliberately ambi...

The mid 20 century witnessed some serious attempts in studies of play and games with an emphasis on their importance within culture. Most prominently, Johan Huizinga (1944) maintained in his book Homo Ludens that the earliest stage of culture is in the form of play and that culture proceeds in the shape and the mood of play. He also claimed that some elements of play crystallised as knowledge s...

We compare two gesture sets for interactive surfaces—a set of gestures created by an end-user elicitation method and a set of gestures authored by three HCI researchers. Twenty-two participants who were blind to the gestures’ authorship evaluated 81 gestures presented and performed on a Microsoft Surface. Our findings indicate that participants preferred gestures authored by larger groups of pe...

Finite-bandwidth effects on the temperature dependence of the mobility of injected carriers in pure organic crystals are explored for a simplifed case of impurity scattering. Temperature-dependent bandwidth effects are discussed briefly through a simplified combination of band and polaronic concepts.
