We are developing a modular electronic device whose goal is to allow users to perceive and respond simultaneously to multiple spatial information sources using haptic stimulus. Each module of this wearable " haptic radar " acts as an artificial hair capable of sensing obstacles, measuring their range and transducing this information as a vibro-tactile cue(More)
The problem of tracking hands and fingers on natural scenes has received much attention using passive acquisition vision systems and computationally intense image processing. We are currently studying a simple active tracking system using a laser diode, steering mirrors, and a single non-imaging detector, which is capable of acquiring three dimensional(More)
We present the development vision of a range of interactive body-worn lighting systems for performance, play, rehabilitation and dis-or altered-ability support. The systems combine experimental and off-the-shelf technologies to arrive at outcomes that require and inspire extended physical and expressive engagement, and afford a range of different learning(More)
We are developing a modular electronic device to allow users to perceive and respond simultaneously to multiple spatial information sources using haptic stimulus. Each module of this wearable " haptic radar " acts as an artificial hair capable of sensing obstacles, measuring their range and transducing this information as a vibro-tactile cue on the skin(More)
This paper describes a finger gesture recognition system based on an active tracking mechanism. The simplicity of this tracking system is such that it would be possible to integrate the whole system on a chip, making it an interesting input interface for portable computing devices. In this context, recognition of gestural characters allows information to be(More)
Recently the miniaturization of mobile devices has progressed and such devices are difficult to have input interface that has wide operation area on their surface. Conventional input interface on a cell phone, such as a touch panel or keypad, has limited operation area. There has been many approaches to handle this problem, but they require users to wear(More)
Mobile and ubiquitous systems create opportunities for new kinds of interactivity in public spaces. Examples of human-technology interactions in public spaces include interactive displays on different scales; mobile systems enabling projection in public environments; smart interactive and reactive objects; tangible interfaces; and public media arts.(More)
We propose a variant of the multi-touch display technology that introduces an original way of manipulating three-dimensional data. The underlying metaphor is that of a deformable screen that acts as a boundary surface between the real and the virtual worlds. By doing so, the interface can create the illusion of continuity between the userpsilas real space(More)
This paper describes a proof-of-principle demonstration of a novel and simple active tracking mechanism using a laser diode, steering mirrors, and a single non-imaging photodetector. Tracking is based on the analysis of a temporal signal corresponding to the amount of backscattered light produced during a rapid, local circular scan (or saccade) around the(More)
