    InfoGrid: Acceptance and Usability of Augmented Reality for Mobiles in Real Museum Contexts
    (Mensch und Computer 2018 - Workshopband, 2018) Ohlei, Alexander; Bouck-Standen, David; Winkler, Thomas; Herczeg, Michael
    In this paper, we present the concept and prototype of the Augmented Reality (AR) app InfoGrid for mobile devices, which enables museum visitors to experience digital media as an overlay for physical exhibits. With InfoGrid, it is possible to view 3D objects, videos, and animations, or listen to audio re-cordings prepared by museum professionals. InfoGrid interfaces with our web-based framework, the Network Environment for Multimedia Objects (NEMO), which stores and handles all data in a cloud-based semantic database. In this contribution, we present the usability field evaluation of InfoGrid in a nature museum, using the System Usability Scale (SUS) questionnaire and additional observations.

    InfoGrid: An Approach for Curators to Digitally Enrich their Exhibitions
    (Mensch und Computer 2018 - Workshopband, 2018) Ohlei, Alexander; Bouck-Standen, David; Winkler, Thomas; Herczeg, Michael
    In this contribution, we present our research on applications for curators to digitally enrich their exhibition. One of the applications we developed is the Augmented Reality app called InfoGrid. The app consists of two components: first, museum professionals can use InfoGrid to augment physical exhibitions with digital content through the web-based content management platform, the ALS-Portal; second, visitors use InfoGrid on their own mobile devices to experience these digital augmentations of exhibits via AR. InfoGrid, as well as the ALS-Portal, interface with our backend system, the Network Environment for Multimedia Objects (NEMO). The NEMO framework provides ALS applications with their application logic, semantic models, and functions as the semantic data storage. Museum professionals can use ALS software to automatically process image or video footage to create 3D objects, which can be aligned and cleaned from artifacts in the ALS-Portal by the help of our web-based 3D object editor. ALS software also contains a web-based video editor, which enables curators to create and edit video files, which can be used in all ALS applications. Through the ALS-Portal, museum professionals can look into usage statistics to improve their exhibitions. We present a field setup of an exhibition of original paintings, sculptures and literature created by Günter Grass, the German Noble Prize winner for literature. The exhibition took place in the “Bremische Bürgerschaft” in the Hanseatic City of Bremen over a period of seven weeks.
