Spatial awareness of autonomous embedded systems by Clemens Holzmann

By Clemens Holzmann

Our surroundings is more and more pervaded by means of embedded structures that are built-in into daily items, built with sensors and actuators, networked between one another and to be had at any time and in any position. those computationally augmented real-world items has to be provided with context-awareness and wish to percentage the perceived context-information to let them to function extra autonomously. Clemens Holzmann investigates the function of spatial contexts for self reliant embedded structures, specifically the placement, course, and spatial extension of gadgets with recognize to an exterior reference approach or different gadgets. the writer provides innovations of spotting, representing, and reasoning approximately qualitative spatial family members and their adjustments through the years, in addition to a suitable structure which has prototypically been carried out in a versatile software program framework. His effects convey that the proposed thoughts are compatible for constructing spatially acutely aware purposes and that qualitatively abstracted family members can represent an sufficient foundation for this goal.

NearMe The NearMe Wireless Proximtiy Server [KH04], which has been developed at Microsoft Research, allows to discover people and things in physical proximity using Wi-Fi. Clients register with the server, scan for Wi-Fi access points and report observed access points and their signal strengths to the server, who compares the data with that of other clients. The server can then send back a list of nearby users and things that have been registered. NearMe provides no absolute location but only proximity information with a resolution in the tens of meters; an a-priori calibration of the environment is not required.

It provides symbolic location information about people who wear badges that are equipped with a microprocessor and an IR transmitter. The badges periodically emit unique user-identifiers, which are collected by IR receivers placed in the environment and sent to a central location server. g. in the form of “proximate selection” which is a user interface technique for emphasizing objects that are located nearby. The ParcTab system and applications are related to this thesis in that location and proximity information are used for building context-aware applications.

The Context Toolkit is based on a distributed architecture which uses XML and HTTP for communication between the components. It is related to the framework presented in this thesis in that it provides context abstractions to applications. In contrast, this thesis specifically addresses the abstraction of spatial relations and the development of spatially aware applications thereof; in this regard, our relation recognizers (cf. 3) are comparable to context widgets which also provide abstract context information and allow applications to register in order to be notified about context changes.
