A system and process for selecting objects in an ubiquitous computing environment where various electronic devices are controlled by a computer via a network connection and the objects are selected by a user pointing to them with a wireless RF pointer. By a combination of electronic sensors onboard the pointer and external calibrated cameras, a host computer equipped with an RF transceiver decodes the orientation sensor values transmitted to it by the pointer and computes the orientation and 3D position of the pointer. This information, along with a model defining the locations of each object in the environment that is associated with a controllable electronic component, is used to determine what object a user is pointing at so as to select that object for further control actions.

The present invention is directed toward a system and process that controls a group of networked electronic components using a multimodal integration scheme in which inputs from a speech recognition subsystem, gesture recognition subsystem employing a wireless pointing device and pointing analysis subsystem also employing the pointing device, are combined to determine what component a user wants to control and what control action is desired. In this multimodal integration scheme, the desired action concerning an electronic component is decomposed into a command and a referent pair. The referent can be identified using the pointing device to identify the component by pointing at the component or an object associated with it, by using speech recognition, or both. The command may be specified by pressing a button on the pointing device, by a gesture performed with the pointing device, by a speech recognition event, or by any combination of these inputs.

The present invention discloses an access control method for common computing environment. The method realizes dynamic access control by combining a hierarchy credit mode with a role-based access control mode. The hierarchy credit mode is a structure with two hierarchies, wherein the bottom credit value determines the role assignment; the upper credit value determines the role activation and the permitted activation. The upper credit value is related to applied context, different upper credit values correspond to different activated roles and permission, thus the obtained service is different. The method is mainly applied in solving the problem of authorization in common computing environment as well as in realizing access control to the applied resources in other dynamic environments.

Methods, apparatus and program products for using historical contextual data in a ubiquitous computing environment. The historical contextual data can be dispersed among components in an environment or logging services as well as stored on a particular component or logging service. The historical contextual data can be used to help create or re-create component configurations within the relevant environment through the use of abstract applications and abstract components. Abstract applications can be specified to create connections with specific components. Abstract applications can also be generalized so that they need not create connections with specific components, but can create component connections that perform a desired function by determining which components to use from the available components, and how to connect the selected components to perform the function.

When interacting and talking with each other, humans are quite successful at conveying information and reacting appropriately. That is, they are able to interpret situational information which in most cases is only implicitly given. This ability is in stark contrast to most of the current state-of-the-art computer and telecommunications systems, which in large are unaware of this context information. Consequently, there has recently been great interest in making applications more context-aware so that they can adapt to different situations and be more receptive to user's needs.

The purpose of this project was to explore how one through examining different kinds of context information can find ways to automatically set a user's presence status. This presence status is useful as it allows for a person to decide whether it is appropriate to initiate communication or not. Further, it was the mission of this project to review how a policy-based approach could be use together with the mentioned aggregated presence status to increase user personalisation of communication. Finally, the project set out to show how one can model and implement such a context-aware system using Ericsson's service creation framework; ServiceFrame.

The project used a model-driven approach (MDA) in which most of the effort went into modelling the functionality of the system using formal UML2.0 models and then transform these into code using code generation tools and MDA viewpoints. During the modelling of the system, it was decided to examine user's context information and from this classify the user's aggregated presence status by utilising a supervised learning classifier. In a proof-of-concept solution, the probabilistic classifier, Naïve Bayes, proved to be an extremely fast and accurate classifier which should be considered as a strong option in any future implementations of the system. Personalisation of communications by design was achieved both through allowing completely personal classification rules, as well as through a policy approach. This policy approach consisted of letting a user construct a personal prioritising of his or hers terminals based on his or her aggregated presence status. It is suggested to expand this approach by also taking the group membership of the entity which requests the user information into account.

Using supervised learning makes sure the system is not to be solely dependent on any particular context data sensor but rather having the ability to adapt to an ever-changing environment. With the expected explosion of context sensors in areas such as ubiquitous computing [15], this ability to adapt will become increasingly important in future context-aware systems. In addition to this flexibility, the use of supervised learning also introduces the ability to classify completely unknown scenarios. This means that even if the classifier encounters a new scenario which is has never seen before, it tries to predict a status based on the underlying previous data. It stated that these predictions often have a high degree of accuracy with the right training data.

The system used the agent oriented architecture, which it is stated has a good support for personalisation as agents generally are used to represent entities in the real world (e.g. users). Through this approach, the system allows for a completely personal classification of a user's current context. By doing so, it is acknowledged that pre-defined rules does not fit everyone, but should be adapted to give each person a high degree of personalisation.

An efficient and adaptive middleware infrastructure called the Event Heap system dynamically coordinates application interactions and communications in a ubiquitous computing environment, e.g., an interactive workspace, having heterogeneous software applications running on various machines and devices across different platforms. Applications exchange events via the Event Heap. Each event is characterized by a set of unordered, named fields. Events are routed by matching certain attributes in the fields. The source and target versions of each field are automatically set when an event is posted or used as a template. The Event Heap system implements a unique combination of features, both intrinsic to tuplespaces and specific to the Event Heap, including content based addressing, support for routing patterns, standard routing fields, limited data persistence, query persistence/registration, transparent communication, self-description, flexible typing, logical/physical centralization, portable client API, at most once per source first-in-first-out ordering, and modular restartability.
