Combining local and global optimization for planning and control in information space
… for controlling a robot with imperfect state information under uncertainty. This question is formulated abstractly as a partially observable stochastic shortest path (POSSP) problem. We assume that the feature-based map of a region is available to assist the robot's decision-making. The POBRM …

Planning in information space for a quadrotor helicopter in a GPS-denied environment
… indoor environments, accurate global positioning information is unavailable, and the vehicle has to rely on onboard sensors to detect environmental features and infer its position. Given that a vehicle small enough to fly indoors can only carry a limited sensor payload, the vehicle's ability to …

Management of Boundary Objects in a Shared Information Space for a Public Works Organization
… program called CITY INFO-PLUS, which represents information via boundary objects in a dynamic contextual manner. This application demonstrates a way for operationalizing the theoretical concept of boundary objects that is taken from the social sciences. An evaluation study of CITY INFO-PLUS was …

Expert system shells in chemistry: CHIRULE, a chiral chromatographic column selection system using similarity searching and personal construct theory
… separations. CHIRULE constructs an n-dimensional information space from a large number of known chiral separations by fragmenting the molecules at their chiral center, producing four molecular fragments. Molecular properties are calculated for each of these fragments. The properties are the axes …

Explorable Information Spaces - Designing Entity Affordances for Fluid Information Exploration
… search tools as primary access points to information, and better support for a wider range of information-seeking behaviors, including exploratory search, serendipity, and orientation. I summarize that goal as Making information explorable and define explorability as the quality of …

Visual discussions : a visual representation of threaded discussion groups
… attention to relevant areas of areas in a large information space.

Minimalist Models and Methods for Visibility-Based Tasks
… state estimations. This is done by analyzing the space of sensing and actuation histories, the history information space. The history information space is compressed into smaller spaces, called derived information spaces, which are used for filtering and planning. By designing and analyzing the …

Situation Awareness: A Network Centric Approach
… and SA have refrained from attempting to model information space dynamism (i.e. dynamic scenarios which may have more than one probable outcome). Few studies have identified the need for a flexible, robust and overarching framework which could model both the network and information space …

Tools for end-user creation and customization of interfaces for information management tasks
Information based tasks rely on software applications that allow users to interact with information in some pre-defined manner deemed appropriate by the application developer or information/content provider. Whereas such an approach facilitates one way of working with the information, it does not …

Spatial peripheral interaction techniques for viewing and manipulating off-screen digital content
When an information space is larger than the display, it is typical for interfaces to only support interacting with content that is rendered within its viewport. To support interacting with off-screen content, our work explores the design and evaluation of several spatial off-screen exploration …

Versioning for the Haystack system
… implementation of a repository for electronic information is presented. While designed with the Haystack system in mind, the repository can easily be used by anyone familiar with RDF. This repository performs the basic task of storing the information that the user collects, in addition to …

Improving memorability in fisheye views
… detail and global context in the same display space. Although fisheyes allow the presentation and inspection of large data sets, the distortion effects can cause problems for users. One such problem is lack of memorability – the ability to find and go back to objects and features in the data. …

Urban Pilot : a dynamic mapping tool for personalizing the city through collective memory
… services. One needs to capture the hidden information patterns of the city in order to experience it in a meaningful way. The volatile, unpredictable randomness of the city life and its ever-changing patterns need dynamic navigational means. Unfortunately, existing devices and their …

Travel Information Search on the Internet: An Exploratory Study
… a travel planning exercise to explore the travel information search on the Internet. The results showed that travelers use a variety of web sites to search for travel information and they have different semantic mental models regarding the same travel destination. Accordingly, they encounter …
