- The use of digital signs simplifies distribution. Importantly, it draws more attention than static signs. A way to increase attention is to add an experienced depth. The paper discusses possible alternatives for extending an existing digital signage system to display stereoscopic 3D contents, comparing a decentralized distribution solution and a centralized solution. A functional prototype system was implemented. A new 3D player was developed to render views from different formats. The implemented system was used to study customer behavior when exposed to digital stereoscopic 3D signage in a direct sales situation. The proportion of sales of selected products related to the total number of sold products varied approximately equally before and during tests. An interview study suggests that the sign did not interact with customer decisions: customers were lost at different stages in this series of steps, among others the sign placement.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This booklet is a report for a case study visit during four day field trip, a group of nine PhD students and their supervisors – all part of the National Research School for Architecture and Planning in the Urban Landscape, APULA – set out to explore what may be considered the outback of Western Europe’s conurbations, the transnational region of Kiruna -Narvik.Both “remote” and “resourceful”, “threatened” and “thriving” (equally relative notions), this region seemed to offer possibilities to reflect upon many of the current tendencies influencing contemporary planning practice and research.

Tidskriftsartikel (refereegranskat)abstract
- Here we present a method for high-precision drilling using an industrial robot with high-bandwidth force feedback which is used for building up pressure to clamp-up an end-effector to the work-piece surface prior to drilling, The focus is to eliminate the sliding movement (skating) of the end-effector during the clamp-up of the end-effector to the work-piece surface, an undesired effect that is due to the comparatively low mechanical stiffness of typical serial industrial robots. This compliance also makes the robot deflect due to the cutting forces, resulting in poor hole position accuracy and to some extent in poor hole quality. Recently, functionality for high-bandwidth force control has found its way into industrial robot control systems. This could potentially open up the possibility for robotic drilling systems with improved performance, using only standard systems without excessive extra hardware and calibration techniques. Instead of automation with expensive fixtures and precise machinery, our approach was to make use of standard low-cost robot equipment in combination with sensor feedback. The resulting sliding suppression control results in greatly improved hole positioning and quality. The conceptual idea behind the force control is useful also in many other robotic applications requiring external sensor feedback control.
