This paper presents experiences on using five different self-report methods, two adopted from literature and three self-created, for collecting information about emotional responses to mobile applications. These methods were used in nine separate field experiments done in naturalistic settings. Based on our experiments, we can argue that all of these(More)
Thispaperprovides a critique of current conceptions of “organizational memory” as presented in a number of recent studies. It briefly reviews some of the rich and varied contributions from both administrative studies and information systems concerning this topic, while aC the same time noting the vagueness of the term as it is commonly used. What is of(More)
Scenarios in HCI are widely used and discussed as written or visual narratives. In this paper, we discuss fruitful conditions for the creation and performance of scenarios particularly for the concept design of mixed realities or wireless devices. Designers are attempting new ways of engaging people in design and experiencing ideas in early design phases.(More)
Designing concepts for new mobile services and devices, poses several challenges to the design. We consider user participation as a way to address part of the challenges. We show how our effort relates to current and past research. In particular, PD (Participatory Design) has inspired us in developing two participatory techniques. The two techniques are(More)
This tutorial introduces participants to Activity Theory, a conceptual approach that provides a broad framework for describing the structure, development, and context of computer-supported activities. The tutorial will consist of lectures, discussion and small group exercises. A Web community will be established so attendees will be able to continue to(More)
Several works have been published describing group performances to experience ideas during early design phases. Beyond practical accounts, performances have been poorly considered in the design literature. By analysing some of these works along with ours, we have inferred three roles of performance in the design of interactive systems: exploring,(More)
This paper describes experiences from using a field testing technique for collecting user experience information for evaluating mobile applications used in everyday life. Our technique is based on the usage of mobile camera phones that are used for capturing video and audio during the use of the mobile application. The users helped researchers in collecting(More)
