The concept of a weakly intrusive ambient soundscape (WISP) is presented as a means to provide a peripheral awareness of processes beyond a user’s immediate attention. The WISP is a component in a larger environment for ubiquitous computing, centered around a conference room scenario. The experiences from a demonstration prototype indicate that the choice(More)
While the navigation metaphor has received widespread support from the HCI community, the views on the usefulness of the navigation approach have a very wide range. Benyon (1998, p 35) argues that “‘Navigation in Information Space’ is not (just) a metaphor, (...) [it] is a new paradigm for thinking about HCI.” On the other hand, Dillon and Vaughan (1997)(More)
We present a ubiquitous service environment for teamwork, supported by Active Documents. The environment consists of a physically dressed conference room and a software architecture based on Java and Jini. At the application level, mobile agent technology provide Active Documents that utilise context information and distributed resources to support users.(More)
The ultimate purpose with socially intelligent agent (SIA) technology is not to simulate social intelligence per se, but to let an agent give an impression of social intelligence. Such user-centred SIA technology, must consider the everyday knowledge and expectations by which users make sense of real, fictive, or artificial social beings. This(More)
Social navigation (SN) emerged as a marriage between one-user-one-system scenarios and CSCW. It is a design approach based on either visualizing traces of other users' activities or on direct or indirect communication between users, with the goal to facilitate locating and evaluating information. Social Navigation has wide-ranging benefits, from social(More)
Now at: IBM Almaden Research Center, 650 Harry Rd., San Jose, CA 95120, USA ABSTRACT We describe the results from user studies of a collaborative, socially enhanced Web space named a CoWeb. We added social navigation in the form of graphical footprints and “new” markers next to the links in the CoWeb. We found that social enhancement of the Web space using(More)
Computer usage is once again going through changes. Leaving behind the experiences of mainframes with terminal access and personal computers with graphical user interfaces, we are now headed for handheld devices and ubiquitous computing; we are facing the prospect of interacting with electronic services. These network-enabled functional components provide(More)
The way people use computing artefacts in local collaborative settings is problematic. The main reason for this is that the tools that are being used to a large extent are designed as personal tools. Constant intrusions on the collaborative task are imposed from lacking support for collaboration, external non-related events, parallel non-related work and(More)
