We present the design and implementation of ForceForm, a prototype dynamically deformable interactive surface that provides haptic feedback. We use an array of electromagnets and a deformable membrane with permanent magnets attached to produce a deformable interactive surface. The system has a fast reaction time, enabling dynamic interaction. ForceForm(More)
This paper describes a concept for supporting distributed hands-on collaboration through interaction design for the physical and the digital workspace. The Blended Interaction Spaces concept creates distributed work environments in which collaborating parties all feel that they are present "here" rather than "there". We describe thinking and inspirations(More)
We present the spoken dialogue system designed and implemented for Virtual Advisers in the FOCAL environment. Its architecture is based on: Dialogue Agents using propositional attitudes, a Natural Language Understanding component using typed unification grammar, and a commercial speaker-independent speech recognition system. The current application aims to(More)
The Future Operations Centre Analysis Laboratory (FOCAL) at Australia’s Defence Science and Technology Organisation (DSTO) is aimed at exploring new paradigms for situation awareness (SA) and command and control (C2) in military command centres, making use of new technologies developed for simulation, virtual reality, and real-time 3D animation. Recent work(More)
Touch surfaces are common devices but they are often uniformly flat and provide little flexibility beyond changing the visual information communicated to the user via software. Furthermore, controls for interaction are not tangible and are usually specified and placed by the user interface designer. Using ForceForm, a dynamically deformable interactive(More)
This paper presents our work towards adapting ForceForm, a 2.5D actuated surface, for use as a medical training apparatus for rebound tenderness, an application area which lacks prior research from computing researchers. Rebound tenderness is used by health practitioners to physically examine a patient's abdomen by applying and then releasing pressure with(More)
This paper describes the implementation of an intelligent Multimedia Presentation Planner (MPP) in a multimodal dialogue system. Following the development of an architecture based on the Standard Reference Model, designed specifically for FOCAL, this implementation has been integrated with an earlier spoken dialogue system. The design now ensures that the(More)
Using magnetic forces to provide haptic information is an area that remains largely unexplored and provides exciting opportunities for interaction that may not otherwise be possible. We present several example applications that illustrate how this technology is well suited to remote site collaboration techniques, conveying state information and simulating(More)

ForceForm is a dynamically deformable interactive surface in which lumps and indents can be created, and feels soft to the touch. In this paper, we present a study to explore users' ability to identify different levels of firmness generated in the soft surface of ForceForm. Our results show that those with medical training, in this case phlebotomists,(More)
