Abstract
Physical maps of a city or region are important pieces of geographical information for tourists and local citizens. Unfortunately the amount of information that can be presented on a piece of paper is limited. In order to extend the map information we propose an augmented reality (AR) system, ARTourMap, for additional information visualization and interaction. This system provides an abstraction layer to develop applications based on the concept of separated logic map tiles taking advantage of a multi-target system where several regions of the map trigger different superimposed graphics. This allows the map to be folded, to be partially occluded, and to have dematerialized information. To demonstrate the proposed system ARTourMap, three layers were developed: a location-based game with points of interest (POIs), a 3D building visualization and an historical map layer. © 2016 The Eurographics Association.

Abstract
The personal characteristics of entrepreneurs can be importantly related to entrepreneurial startup intentions and behaviors. A country-moderated hypothesis including the relationship between an individual's risk-taking propensity and entrepreneurship (behaviors or intentions of the person) was conceptually developed and empirically tested in this study. The data collection was performed through a structured questionnaire. Multinominal logistic regression was used for analyzing data obtained from 1,414 students in six countries. The crucial contribution of this research is the clarification of the character of risk-taking propensity in entrepreneurship and the indication that the risk-taking propensity-entrepreneurship relationship can be moderated contingent on power distance.

Abstract
Teenagers have been identified as an audience group that is often excluded from museum curatorial strategies. One strategy to counteract this problem is to involve cultural heritage professionals (CHPs) in the design process of museum based digital experiences targeted at teens. In this paper, 12 CHPs from a local natural history museum took part in a co-design activity over 20 hours, aiming to create and deploy digital tours for teenagers aged between 16-19. We present the three prototypes that derived from these design sessions. These were then tested by both 12 CHPs and 12 teenagers separately, and we report on lessons learned from the evaluation of these prototypes by both groups. © Dupré et al.
