Abstract:
This thesis explores the idea of how to use physical objects with digital functionality to interact and communicate with each other in order to assist people with carrying out their everyday activities. The main contribution of this thesis is the proposition of the Open Object concept and its respective supporting framework. An Open Object is a physical object that is capable of network connectivity enabling it to (a) expose and share its capabilities to the outside environment including people and other objects; (b) request the use of capabilities from other objects or external services when needed; and (c) allow people to modify or introduce new functionalities, effectively changing the object's behaviour. This is to be contrasted with existing object or service oriented models whose functionality, although exposed and accessible, is not normally open to changes from the outside. Basic Open Objects are then used as building blocks to construct assemblies of objects that interact and communicate with each other to manage themselves independently and work as a single entity, which we call Open Super-Object. The key issue of Open Super-Objects is how they can be best constructed through the specification of rules that control and coordinate their interactions. This leads to a general approach of architecting, specifying and implementing Open Objects in such a way that the overall coordination of more complex objects is supported by composing the capabilities of simpler objects, regardless of their internal implementation and structure. Throughout the thesis, Open Objects are presented through a series of scenarios illustrating how the openness of simple and Open Super-Objects can be specified and implemented. However, to investigate the practical value of Open Objects, we also present and evaluate a prototype implementation of a real-world scenario. In this scenario, an Open Super-Object situated in an office environment notifies people of the availability of a co-worker. We also aggregate a collection of methodologies for implementing different standard computing and software patterns to produce a lightweight Open Object system. We conclude the thesis with a summary of the achievements and a discussion of future work, in particular how Open Objects can be used as a platform to support end-user development.
