In this paper we propose a novel interaction technique that creates the illusion of tactile exploration of museum artefacts which are otherwise impossible to touch. The technique meets the contextual necessity, often requested by museum curators, to background technology and to direct the focus of the museum visitor's experience to the artefact itself. Our approach relies on the combination of haptic interaction and the adaptation of a well-known illusion that enables museum visitors to make sense of the actual physical non-touchable artefact in an embodied way, using their sensory and motor skills. We call this technique Haptic Augmented Reality.

– Conventional non-digital physical stop-frame animation is based on the inherently intuitive direct two handed manipulation of a passive figure. Digital media may provide powerful software tools for animation but they do so through less intuitive interfaces. We argue that ...

1. Background Recent research on creativity and computers has focused on the creation of new applications and devises to assist designers during the early conceptualising stage of the design process, the germinal phase. Through literature searches, most of the available data ...

Applied artists and product designers encounter difficulties in adapting to digital tools which could theoretically improve their practice. The Tacitus project has adopted user-centered methodologies to investigate the potential advantage offered by digital media, particularly during the germinal phase of the design process, by developing a novel interface which exploits spatial input, haptic force-feedback and stereovision. This paper presents theoretical implications and experimental results obtained from the first studies of an early prototype for sketching in three dimensions, with the focus on qualitative evaluation. The underlying principle of the 3D sketching 'widget' is to support designers by merging those qualities typically offered by sketching and modeling with advantages of digital interfaces.

This paper investigates the potential benefit of "gestural" and haptic (touch) interaction and stereovision in computing for three-dimensional form conceptualisation and spatial reasoning in the germinal phase of the design process. Specifications for suitable digital support will be extracted from current design practice in concept design with the focus on "physical concept models". Potential advantages and limitations will be briefly

An algorithm is presented to compute smoothed local symmetries on a MIMD architecture. Based on Brady and Scott's Connection Machine algorithm, it is adapted to reduce the synchronisation and communication overheads involved. Using an evidence accumulation approach similar to the Hough transform for circle detection, this algorithm can compute both local and rotational symmetries simultaneously. Implementation on an array of transputers is described and the results discussed.

In this paper, we propose a new approach to the map building task: the implementation of the Spatial Semantic Hierarchy (SSH), proposed by B. Kuipers, on a real robot fitted with an omnidirectional camera. The original Kuiper's formulation of the SSH was slightly modified, in order to manage in a more efficient way the knowledge the real robot collects while moving in the environment. The sensory data experienced by the robot are transformed by the different levels of the SSH in order to obtain a compact representation of the environment. This knowledge is stored in the form of a topological map and, eventually, of a metrical map. The aim of this paper is to show that a catadioptric omnidirectional camera is a good sensor for the SSH and nicely couples with several elements of the SSH. The panoramic view and rotational invariance of our omnidirectional camera makes the identification and labelling of place a simple matter. A deeper insight is that the tracking and identification of events on an omnidirectional image such as occlusions and alignments can be used for the segmentation of continuous sensory image data into discrete topological and metric elements of robot maps. Such a combination of the SSH and omnidirectional vision provides a powerful general framework for robot map making and indeed new insights into the concept of "place" in such activities. Some preliminary experiments performed with a real robot in a unmodified office environment are presented.
