The use of reflection lines and specular high lights for the quality control of car body surfaces is an important issue in the development process of a car. The interactive examination is based on standard graphics tools such as the SceneViewer of OpenInventor which simulates reflection lines by using striped environment maps. The interpolation of texturing and shading values is critical and re...

Abstract In this research, we proposed a new display with a dynamically changeable softness parameter called ”ClaytricSurface”. While conventional displays generally have fixed softness, we focused on interactive displays with a controllable softness property. We developed a prototype system by...

* Combined free-form and technical surfacing in one environment means no data transfer between design and engineering * Design precise curves and surfaces to achieve highly-engineered, manufacturable products * Confidently explore design variants by making fully associative changes at any time * Intuitive user interface provides direct surface editing capabilities, real-time feedback and allows...

Inspired by the role sound and friction play in interactions with everyday objects, this work aims to identify some of the ways in which kinetic surface friction rendering can complement interactive sonification controlled by movable objects. In order to do this, a tactile system is presented which implements a movable physical object with programmable friction. Important aspects of this system...

This paper introduces a novel kinesthetic interaction technique for interactive floors. The interaction techniques utilize vision-based limb tracking on an interactive floor – a 12 m glass surface with bottom projection. The kinesthetic interaction technique has been developed for an interactive floor implemented in a school square. The paper discusses the kinesthetic interaction technique and ...

Interactive surfaces are becoming more and more common in research and everyday use. Recent research has focused on hardware technologies and basic interaction techniques. While the WIMP paradigm is the prevalent standard for desktop computers, there is no consensus yet on similar paradigms for interactive surfaces. In order to explore novel interaction paradigms for interactive surfaces, resea...

Minimization techniques are commonly adopted methodologies for retrieving a 3D surface starting from its shaded representation (image), i.e. for solving the widely known shape from shading (SFS) problem. Unfortunately, depending on the imaged object to be reconstructed, retrieved surfaces often results to be completely different from the expected ones. In recent years, a number of interactive m...

Technology-based activities are becoming more popular in therapy programs, and direct-touch interactive tabletops seem particularly suited to many therapy tasks. To better understand the potential benefit of interactive tabletops in rehabilitation, we examined users’ attitudes as they performed rehabilitation activities on a multi-touch tabletop and a normal, non-interactive surface. This revea...

We develop a dynamic, free-form surface model which is useful for representing a broad class of objects with symmetries and topological variability. The new model is based upon swung NURBS surfaces, and it inherits their desirable cross-sectional design properties. It melds these geometric features with the demonstrated conveniences of surface design within a physics-based framework. We demonst...

Interactive image segmentation algortihms incorporates small amount of user interaction to define the desired content to be extracted, has received much attention in the recent years. We propose a robust and accurate interactive method based on the recently developed continuous-domain convex active contour model. The proposed method exhibits many desirable properties of an effective interactive...
