Contribution of 3D photogrammetry for ballistic analysis of lithic projectiles
Vojtěch NOSEK | Ludmila KAŇÁKOVÁ HLADÍKOVÁ (Department of archaeology and museology, Masaryk University, Brno Czech republic) Keywords: 3D photogrammetry ; ballistic analysis ; lithic projectiles ; archaeometry Abstract: We have developed new method for archaeometric analysis of lithic projectiles using 3D photogrammetry and virtual models of projectiles. Till these days ballistic analysise of these archaeological artefacts was done simple by using simple formulas with just few exact metric values so there was possibility of innacurate result. Our method use high definition 3D models of projectiles which provides much more accurate hard data which can be later used for statistical or balistic analyse. Several hundreds of lithic projectiles dated from late neolithic and early bronze age from burial sites as Mýtná Nová Ves, Holešov and several more were analysed and evaluated by our new method with very interesting results. Such number of examined artefacts provides solid base for statistical evaluation of such important complex of artefacts. Digitization using photogrammetry and 3D scanning u provides great oportunities for studying lithic projectiles. In the first place virtual 3D models are easy to orient in virtual space so they can be non – destructive studied in detail, for example making of cross – section cuts and profiles of artefacts or just their parts. Secondly, precise virtual images are great tool for morphometric analysis using landmarks and other applications. Therefore we present our new method as combination of photogrammetric documentation of lithic projectiles and archaeometric and ballistic analyse of archaeological...

After Pokemon: Discovering The Local Heritage By Gaming
Livia STEFAN | Dragos GHEORGHIU (National University of Arts Bucharest, Romania) Keywords: location-based/Augmented Reality mobile applications, Pokemon, heritage Abstract: With this presentation, the authors will share their previous experience in the domain of location-based/Augmented Reality mobile applications for heritage and will propose a game-play scenario. The research idea was to design a discovery mobile game, similar to the well-known Pokemon. This game should help players, and especially the younger ones already trained with the Pokemon game-play, discover the local heritage under the form of hidden Points-of-Interest (POIs). In an area around the heritage locations several information are superimposed over the real-life landscape, not in a chronological order, but under the form of cultural categories, e.g. HISTORY, HISTORIC ART, HISTORIC ARCHITECTURE. Depending on the location in which the player is situated, he will receive one or several informative layers. Some layers will indicate explicit POIs of objectives, while others will invite to POIs’ discovery. Here comes into scene the gaming part, i.e. these layers will provide hints to help players find the POIs, and also to reach a new gaming level with richer multimedia information (videos or small 3D reconstructions). The hints will also involve information learned from previous levels. Unlike Pokemon which is more a gamification application with the objective to entertain the players while learning biology, the present concept scenario is more a serious game, with greater educational and cultural awareness impact. Different challenges, e.g. the design of an engaging AR game, either single or multi-player, or which technologies best serve the objectives, can be...
