ABSTRACT:Providing mobile location-based information for pedestrians faces many challenges. On one hand the accuracy of localisation indoors and outdoors is restricted due to technical limitations of GPS and Beacons. Then again only a small display is available to display information as well as to develop a user interface. Plus, the software solution has to consider the hardware characteristics of mobile devices during the implementation process for aiming a performance with minimum latency. This paper describes our approach by including a combination of image tracking and GPS or Beacons to ensure orientation and precision of localisation. To communicate the information on Points of Interest (POIs), we decided to choose Augmented Reality (AR). For this concept of operations, we used besides the display also the acceleration and positions sensors as a user interface. This paper especially goes into detail on the optimization of the image tracking algorithms, the development of the video-based AR player for the Android platform and the evaluation of videos as an AR element in consideration of providing a good user experience. For setting up content for the POIs or even generate a tour we used and extended the Open Geospatial Consortium (OGC) standard Augmented Reality Markup Language (ARML).

“…As shown throughout the historical overview, humans were already in the Prehistory using many of such natural techniques of interaction. Nowadays, these are studied in the area of Human Computer Interaction (HCI), and mimicked in natural user interfaces [Val08]. Introducing natural interfaces in modelling and, specifically, combining them with conventional modelling tools could significantly improve the use and utility of such tools.…”

While modelling research typically concentrates on its more technical and formal aspects, this paper provides a case for what we coin natural modelling. Modelling has always been and will always remain a humanintensive activity. To be adopted at large, modelling technologies should be perceived as natural as possible. In order to characterise what natural means, this paper briefly provides an anthropological and historical perspective on modelling. Constituting per se a first contribution, this retrospective allows to exhibit fundamental modelling concepts, spanning across ages. By looking backwards to understand what was natural (in) modelling in the past, this paper aims to define some elements for what could what computer-assisted natural modelling could be in the future. More specifically, it is argued that (1) the need for compromises between flexibility and formality is rather natural than extreme, (2) languages are emergent by their very nature and continuously evolve, and (3) natural interaction with modelling technology should be provided to all stakeholders, as it strongly promotes stakeholders participation. Although these aspects took different forms in historical developments of technology, we argue that the principles are still relevant today, and that these should be considered in the future research. The paper ends with some simple illustrations, which help provide the insight on how computer-assisted natural modelling could look like in a possible future.

“…The interest in the scientific and industrial communities is in providing a natural interaction with machines. The basic idea is that if people naturally communicate through gestures, expressions, movements, and discover the world by looking around and manipulating physical stuff, they should be allowed to interact with technology in the same way (Valli, 2008). An example of natural interaction is the use of spatial 3D gestures, as those provided by the WiiMote.…”

“…Using users' actions to control the interaction can be done also exploiting computer vision techniques to analyze images of the user's movements and translate them into actions in the virtual environment. In order to allow algorithms to work also in very dark environments, camera and lights in the Near-Infrared are often used (Valli, 2008). The Sony EyeToy device, using a color digital camera, was the first attempt to use computer vision for gesture recognition in computer games.…”
