Automatically adapting user interfaces for hands-free interaction

Abstract: The method includes automatically, without user input and without regard to whether a digital assistant application has been separately invoked by a user, determining that the electronic device is in a vehicle. In some implementations, determining that the electronic device is in a vehicle comprises detecting that the electronic device is in communication with the vehicle (e.g., via a wired or wireless communication techniques and/or protocols). The method also includes, responsive to the determining, invoking a listening mode of a virtual assistant implemented by the electronic device. In some implementations, the method also includes limiting the ability of a user to view visual output presented by the electronic device, provide typed input to the electronic device, and the like.

User interface for information retrieval system

Abstract: An improved information retrieval system user interface for retrieving information from a plurality of sources and for storing information source descriptions in a knowledge base. The user interface includes a hypertext browser and a knowledge base browser/editor. The hypertext browser allows a user to browse an unstructured information space through the use of interactive hypertext links. The knowledge base browser/editor displays a directed graph representing a generalization taxonomy of the knowledge base, with the nodes representing concepts and edges representing relationships between concepts. The system allows users to store information source descriptions in the knowledge base via graphical pointing means. By dragging an iconic representation of an information source from the hypertext browser to a node in the directed graph, the system will store an information source description object in the knowledge base. The knowledge base browser/editor is also used to browse the information source descriptions previously stored in the knowledge base. The result of such browsing is an interactive list of information source descriptions which may be used to retrieve documents into the hypertext browser. The system also allows for querying a structured information source and using query results to focus the hypertext browser on the most relevant unstructured data sources.

Method and apparatus for analyzing performance of data processing system

Abstract: A method and apparatus for analyzing the performance of a data processing system, particularly a distributed data processing system, provide a system user with tools for analyzing an application running thereon. Information about the flow and performance of the application can be specified, captured, and analyzed, without modifying it or degrading its performance or data security characteristics, even if it is distributed across multiple machines. The user interface permits the system user to filter the performance information, to set triggers which the performance analyzer is able to reduce and/or combine, to observe multiple time-synchronized displays of performance data either in real time or post mortem, and to play and re-play the operation of an automatically generated application model. The invention is implemented in part by providing suitable Application Program Interfaces (APIs) in the operating system of the data processing system.

DIVE A multi-user virtual reality system

Abstract: The Distributed Interactive Virtual Environment (DIVE) is a heterogeneous distributed virtual reality system based on UNIX and Internet networking protocols. Each participating process has a copy of a replicated database and changes are propagated to the other processes with reliable multicast protocols. DIVE provides a dynamic virtual environment where applications and users can enter and leave the environment on demand. Several user-related abstractions have been introduced to ease the task of application and user interface construction. >
