MoMEx: Mobile Multimedia-Augmented Exhibition SystemThe MoMEx system enables for a customized multimedia-augmented presentation of exhibited objects on different mobile devices like notebooks, tablet PCs, pocket PCs, or smart phones. Thereby, the presented content is supplied to the system once in best quality. The system itself then adapts the supplied content either in advance (local guide) or dynamically at run-time (networked guide) to the needs of the consumer as well as the capabilities of the consumer's terminal.
Mobile Exhibition GuideThe Mobile Exhibition Guide is the result of the pilot project MultiMundus. Although the contents are currently tailored to some exhibited objects in Minimundus Klagenfurt, the system enables for a multimedia-augmented presentation of object in arbitrary closed and open-air showrooms. In its first stage of expansion, the guide offers an interactive navigation through the exhibition area by a map and interactive presentations of selected exhibited objects on rentable (i.e. pre-configured) mobile devices. The following pictures give a rough impression about the system on the example of the open-air museum Minimundus.

Targets of Audience:
Local GuideThe local exhibition guide works without wireless network. The presented content of exhibited objects is adapted in advance to the capabilities of the consumer's device and provided on a storage card.
The local guide makes mainly sense in situations, when the environmental conditions do not allow a meaningful usage of a wireless network (e.g. in caves), or when the consumer's device is not equipped with a WLAN adapter. In contrary to the networked guide, the local guide does not enable for querying real-time statistics about the usage of the guide in the exhibition area.
Networked GuideThe networked guide connects to a central server through a wireless network. In this scenario, the server adapts the presented contents to the exhibited objects dynamically to the capabilities of the consumer's device (screen, computing power) and to the prefereces of the consumer (language, age, interests).
The main advantages of the networked guide are the possibility to dynamically show real-time data from live-servers (e.g. advertisment), and to query real-time statistics about usage of the system. The latter enables the operator to dynamically adapt presentations according to statistical results.
Content Management SystemThe Content Managemet System is a web-based application that facilitates the management of profiles and object presentations on the server. This enables the presentation designer to upload various media contents (texts, images, videos, audios) to the server and to assign this contents to objects. The composition of the contents to an object presentation is possible with an integrated presentation editor.
The main advantage of the CMS lies in the single provision of media contents in an optimal resolution and quality. If e.g. the maximum supported screen resolution of a consumer device is 640x480 pixels, the video shall be provided in VGA resolution. When the server needs to serve a consumer device with a much smaller resolution, then it automatically adapts the video to a size proper for the requesting device. The same holds for all other kinds of visual content like texts and images, of course.
Server Module for Real-time StatisticsThe server module for real-time statistics is an optional component for the networked variant of the mobile exhibition guide. The module enables for an analysis of session-related information about the usage of a mobile exhibition guide, like consumed objects, visiting path in the area, or the selected profile. Due to the real-time characteristic of this module, the system can take care about the needs and interests of the consumer and offer her/him appropriate adapted content, dynamically.
The statistics module is also available for the local and rentable variant of the mobile guide. However, real-time queries and analysis are not possible with this variant. Instead, the session-related data and the statistical results are available to the operator, when the consumer returns the guide at the end of the visit.
AdViSTec: Adaptive Video Streaming TechnologyThe adaptive video streaming technology enables for a server-side, dynamic adaptation of video content to capabilities of consumer devices (resolution, color depth, computing power) as well as to the instantaneous load of the used transmission network. AdViSTec is based on the open source video toolkit ViTooKi, which is the primary scientific result of the ADMITS project (see menu item Mission).
In contrary to the MoMEx system, AdViSTec is not directly targeted to end consumers. Moreover, it is a technique which can be integrated in server and proxy systems to improve the supply of end consumers. For example, AdViSTec is also part of the MoMEx server to dynamically adapt audiovisual contents.
