Interaction is increasingly a public affair, taking place in our theatres, galleries, museums, exhibitions and on the city streets. This raises a new design challenge for HCI - how should spectators experience a performer's interaction with a computer? We classify public interfaces (including examples from art, performance and exhibition design) according(More)
This paper explores and evaluates the support for object-focused interaction provided by a desktop Collaborative Virtual Environment. An experimental “design” task was conducted, and video recordings of the participants' activities facilitated an observational analysis of interaction in, and through, the virtual world. Observations include:(More)
This paper explores interfaces to virtual environments supporting multiple users. An interface to an environment allowing interaction with virtual artefacts is constructed, drawing on previous proposals for 'desktop' virtual environments. These include the use of Peripheral Lenses to support peripheral awareness in collaboration; and extending the ways in(More)
Delay is an unavoidable reality in collaborative environments. We propose an approach to dealing with delay in which 'decorators' are introduced into the interface. Decorators show the presence, magnitude and effects of delay so that participants can better understand its consequences and adopt their own natural coping strategies. Two experiments with(More)
SHAPE, "Situating Hybrid Assemblies in Public Environments", is an EU Future and Emerging Technologies project of the Disappearing Computer initiative, concerned with designing and developing novel technology to enhance interpersonal interaction in public locales: exploratoria, galleries, and museums, for example. This paper outlines a use of hybrid reality(More)
The Citywide project is exploring ways in which technology can provide people with rich and engaging digital experiences as they move through physical space, including historical experiences, performances and games. This paper describes some initial results and experiences with this project based upon two prototype demonstrators. In the first, we describe(More)
This paper describes an activity designed for a site of special interest in which clues to its history are gathered as visitors explore the site before interacting with two displays which reveal details of key past events. We investigate a design approach in which electronically tagged paper is used both to weave the visit together and configure the(More)
Cooperative gestures are a key aspect of human-human pro-social interaction. Thus, it is reasonable to expect that endowing humanoid robots with the ability to use such gestures when interacting with humans would be useful. However, while people are used to responding to such gestures expressed by other humans, it is unclear how they might react to a robot(More)
We look at differences between the experience of virtual environments and physical reality, and consider making the technical limitations which cause these differences 'visible', aiming to provide resources to enhance communication between users. Three causes of such discrepancies are considered to illustrate this idea: field-of-view; haptic feedback; and(More)
