The role of computers in the modern office has tended to split our activities between virtual interactions in the realm of the computer and physical interactions with real objects that have been part of the traditional office infrastructure. This paper discusses a variety of scenarios we have

Two branches of the trend towards "agents" that are gaining currency are interface agents, software that actively assists a user in operating an interactive interface, and autonomous agents, software that takes action without user intervention and operates concurrently, either while

latitudinal gradients 27, 28 , black carbon has opposing effects of adding energy to the atmosphere and reducing it at the surface. Furthermore the forcing has significant latitudinal gradients. It alters the radiative forcing through a complex web of processes 7 . The first concerns the increase in top

this paper. Pleasingly, the arrow interface turned out to be applicable to other kinds of non-monadic library also, for example the fudgets library for graphical user interfaces [CH93], and a new library for programming active web pages. These applications will be described in sections 6 and 9

for creativity that might assist designers in providing effective tools for users: (1) Collect: learn from previous works stored in libraries, the Web, etc.; (2) Relate: consult with peers and mentors at early, middle, and late stages; (3) Create: explore, compose, evaluate possible solutions; and (4) Donate

, which combine complex navigation patterns with sophisticated computational behavior. We argue that a method providing systematic guidance to design is needed. Next, we introduce OOHDM, describing its main activities, namely: conceptual design, navigational design, abstract interface design

Understanding the extent to which people’s search behaviors differ in terms of the interaction flow and information targeted is important in designing interfaces to help World Wide Web users search more effectively. In this paper we describe a longitudinal log-based study that investigated

to face speech. In this paper we present Chat Circles, an abstract graphical interface for synchronous conversation. Here, presence and activity are made manifest by changes in color and form, proximity-based filtering intuitively breaks large groups into conversational clusters, and the archives of a

. Their cognitive and physical behaviors were captured using Lotus ScreenCam, a Windows-based software package that captures and replays ac-tivities recorded in Web browsers, such as Netscape. Their affective states were captured via a one-on-one exit interview. A new measure called “Web Traversal Measure

Abstract Since the early 1970s, decision support systems (DSS) technology and applications have evolved significantly. Many technological and organizational developments have exerted an impact on this evolution. DSS once utilized more limited database, modeling, and user interface functionality
