| Classical problem for creators of virtual museum is how to place showpieces in environment to utilize them to make the exploration of museum more interesting and if it´s possible interactive. This can be achieved by insertion of computing best views of exposed 3D models and it can be improved with using knowledge from visual perception. For example while searching the best or worst view on object we use combination of methods based on our pre-research questionnaires(Fig.1) and to gain the attention of observers we use rules from Gestalt psychology(Fig.2). Another goal of our research is oriented on virtual galleries. We would like to know where to place the observer so he can perceive the painting similarly to how artist intended(Fig.3). And for the detailed view and explanation of saliency parts of painting we created application Artscan(Fig.7). We are also interested in the frame of paintings and pictures. In our paper we examine how change of the frame influences the observer while viewing the painting(Fig.4) and how the position of frame in consideration of the picture changes the meaning of paintings(Fig.5). For this purposes we created application Framepower(Fig.6), where visitor can change the frames and position of object. |
