A user’s physical and virtual environments are becoming increasingly interwoven. Mobile and embedded devices have become more the rule than the exception: many present-day users are inexperienced when it comes to traditional computers, but are in daily contact with computerized systems. The increasing diversity of all kinds of devices, together with the(More)
The past few years, multimodal interaction has been gaining importance in virtual environments. Although multimodality renders interacting with an environment more natural and intuitive, the development cycle of such an application is often long and expensive. In our overall field of research, we investigate how modelbased design can facilitate the(More)
This paper presents FluidPaint, a novel digital paint system using real wet brushes. A new interactive canvas, accurately registering brush footprints and paint strokes in high precision has been developed. It is based on the real-time imaging of brushes and other painting instruments as well as the real-time co-located rendering of the painting results.(More)
For several years, virtual environments (VEs) are promising applications to explore and manipulate 3D data and 3D worlds. Those environments are designed to be intuitive and easy to use, however, in practice no ideal solution has been proposed yet. Designers and researchers always have to make compromises due to the complexity of the human senses and(More)
Leveraging interactive systems by integrating adaptivity is considered as an important key to accommodate user diversity and enhance user interaction. A virtual environment is a highly interactive system which involves users performing complex tasks using diverse 3D interaction techniques. Adaptivity has not been investigated thoroughly in the context of(More)
Computer-supported rehabilitation can benefit many groups of patients. However, when designing such a therapy, it is important to take the characteristics of the patient population and the wishes of the therapists involved into account. This paper therefore focuses on the requirements of rehabilitation games for Multiple Sclerosis patients. As we have(More)
This paper presents a novel interface for a digital paint system: IntuPaint. A tangible interface for a digital paint easel, using an interactive surface and electronic brushes with a tuft of bristles, has been developed. The flexible brush bristles conduct light by means of total internal reflection inside the individual bristles. This enables to capture(More)
Designers and developers of virtual environments have to consider that providing adaptation in virtual environments is important to comply with users’ different characteristics. Due to the many possibilities of adaptation that a designer can think of, it is necessary to support the integration of adaptation in the application in a rapid and practical way.(More)
