Abstract:

The article presents the concept of supporting training in the reconstruction of archaeological objects in virtual 3D space. The authors are investigating the use of the latest technology of three-dimensional visualisation in order to improve and enrich the reconstruction process of acquired museum artefacts. Reconstruction of objects is based on actual artefacts. Their digital representations were obtained in the process of 3D scanning using such scanners as Artec Eva and Spider.

The proposed solution uses Oculus Rift DK2 virtual reality glasses as an interactive image projector. The process of manipulation (touch, object translation) is supported by the Leap Motion device. This solution allows manipulation of digital representations of real objects comparable to natural interaction in reality. Naturalness of manipulation is a key element of the system as it blurs the barrier between the current way of working (manual alignment of artefacts) and the use of ultramodern technology. A decisive advantage of virtual reconstruction is the absence of gravity. Artefacts in virtual space can be seen from every side and "hang" in the space ahead, adding further elements. Their structure does not require adhesive for joining artefacts and does not fall apart in movement, there is also no fear of damaging a valuable artefact. It is also possible to place an element at a distance from the rest, in the absence of the connecting portion. The position of an object relative to the others will be preserved when moving the whole.

An important feature is also the possibility of storing the specific components of the various alternative versions as well as the whole process of their fitting together. Saved sequences can be used as training material, transferable between centers having adequate technical backing, cooperating at a distance. In addition, it is possible to exchange objects, supply the missing objects, or even create a global directory of archaeological artefacts from selected periods.

Records of artefacts reconstruction may be supplemented by multimedia guidance based on knowledge of domain experts, indicating both the characteristics of artifacts and presenting the correct procedure for reconstruction of this era.

The authors have entered into cooperation with museum Institutions in Lublin (Poland) and Samarkand (Uzbekistan) to produce and test pilot tutorials in the researched environment. The tutorials are created in collaboration with an archeology expert at the Lublin Museum.

The result is an environment allowing to conduct demonstrations and training in the reconstruction of archaeological objects, giving the impression of participation in this process, without using real artefacts or their copies. Such an environment will help to expand the availability of knowledge in this field for all those interested in cultural heritage preservation and make the offer of cultural heritage institutions more attractive.
