Der Informations-Kiosk bietet Studierenden Informationen über aktuelle und offene Projekte und Abschlussarbeiten, Veranstaltungen sowie Live-Daten zum Mensaangebot, Nahverkehr oder dem Wetter. Für diese Anwendung werden die Anforderungs- und die Risikoanalyse, die Gestaltung und die technische Realisierung gemäß den Phasen der Softwareentwicklung beschrieben. Der Kiosk wird mit einem CMS implementiert und durch einen Webserver im Labor zur Nutzung bereitgestellt. Es wird gezeigt, dass die Entwicklung alle Basis- und Leistungsanforderungen erfüllt und auf Grundlage der entwickelten Architektur des Continuous Software Development Entwicklung und Betrieb integriert.
The late immersion of multi-touch sensitive displays enables the use of tangibles on multi-touch screens. There a several wide spread and/or sophisticated solutions to fulfill this need but they seem to have some flaws. One popular system at the time of writing is an overlay frame that can be placed on a normal display with the corresponding size. The frame creates a grid with infrared light emitting diodes. The disruption of this grid can be detected and messages with the positions are sent via usb to a connected computer. This system is quite robust in matters of ambient light insensitivity and also fast to calibrate. Unfortunately it is not created with the recognition of tangibles in mind and printed patterns can not be resolved. This article summarizes an attempt to create fiducials that are recognized by an infrared multi-touch frame as fingers. Those false fingers are checked by a software for known patterns. Once a known pattern (= fiducial) has been recognized its position and orientation are send with the finger positions towards the interactive software. The usability is tested with an example application where tangibles and finger touches are used in combination.
