Abstract: For services which are meant to be used mainly inside buildings, a distribution using global app stores is inappropriate. Instead this work presents a provisioning system (BLISS) for building-linked location-based services. The multi-purpose application MultiApp implements the client-side of the BLISS specification. When a user enters a building, MultiApp instantaneously detects available services and allows to install and execute them. The client part of services is executed within the MultiApp environment and can provide functionalities similar to those offered by native applications. BLISS facilitates developing indoor location-based services by providing bi-directional communication between service providers and clients.

Abstract: Until now no general applicable technology for indoor localization has prevailed. As a result, there are many approaches to model buildings for indoor navigation being developed. Most of them are very expensive to apply. This work presents a tool for graphically adding navigational data to existing maps. It further demonstrates how to use the created map for routing as pure web application which can be combined with any positioning technology. As SVG is used as format for the map, it analyses performance of rendering and manipulating SVGs on different devices. We show that even large maps can be displayed on current mobile Android devices sufficiently fast for usage as indoor navigation application.

Abstract: Developers can use cross-platform mobile development tools to create smartphone apps that meet user expectations, but existing XMTs need improvement.
