In this paper we approach the problem of managing large visual sets of data on small mobile devices. While current approaches either focuses on 1) scrolling on the mobile device, or 2) reducing the content in various ways (e.g. zooming, automatic redesign depending on the screen size of a mobile device, etc) our approach is to scroll with the mobile device… (More)
For educational purposes, Virtual Reality (VR) has been proposed as a technological breakthrough that holds the power to facilitate learning. Though, most efforts within the VR community have focused on applications designed to fulfill purposes of training, such as vehicle simulators, medical and military training. While this area is not at all unimportant… (More)
This paper reports an interpretive case study conducted at three different airports in Sweden and Norway during 1999. The focus of the study has been to establish an understanding of the work practice of flight technicians and the use of IT support tools for aircraft maintenance. By use of observations, interviews and document reviews, we found three main… (More)
We present an interaction technique which could be used to ease the well-known problem of browsing large interface surfaces---in particular web pages---on small screen devices. A prototype implementation is introduced and discussed, turning some of the traditional notions of direct manipulation inside-out.
The Reality Helmet is a wearable device providing a novel form of interactive experience, in which the user's vision and hearing is completely shielded off from the world. Video and sounds are sampled by the Helmet from the surrounding environment, but through computer processing sounds are presented to the wearer as vision and sights are turned into a… (More)
The thesis presented in this paper outlines a notion of computing named Embodied Systems. It is suggested that this concept will move the computer devices from the desks to the users' bodies. The users would then, apart from merely controlling the actual computing itself, also control and decide the context in which the computing takes place. As a step… (More)
In the debate on rigor and relevance in MIS Quarterly Vol. 23 No. 1, March 1999, some models that presented the concepts as conflicting were presented. This paper reviews the debate, defines a number of concepts, and concludes by presenting a model of the relationships between rigor and relevance that is more complete with respect to the earlier debate;… (More)
This Master's thesis studies how the technologies of today could be developed to better support education. An analysis is conducted of digital learning tools on the educational technology market. Based on this analysis a conclusion is made that while many other digital tools for education are well suited for their use, only a few computers are designed… (More)
