New technologies and materials enable the physical form of display surfaces to become dynamic in terms of shape and movement. This enables devices to form a more intimate relationship with software data and the user’s environment. The research area of actuated interfaces aims at leveraging these qualities to enhance interaction with and representation of digital information, as well as creating...

A current challenge in augmented reality applications is the accurate superimposition of synthetic objects on real objects within the environment. This challenge is heightened when the real objects are in motion and/or are nonrigid. In this article, we present a robust method for realtime, optical superimposition of synthetic objects on dynamic rigid and simple-deformable real objects. Moreover...

The research in the field of assembly operations mainly focuses on the handling of rigid objects. Although nonrigid objects like ropes, wires, or steels springs must be handled as well. Therefore, our research investigates the sensorbased handling of deformable linear objects in the field of assembly operations. In this paper, we discuss guidelines for a task description that is able to cope wi...

In this paper, we propose a stable and efficient algorithm for animating mass-spring systems. An integration scheme derived from implicit integration allows us to obtain interactive realistic animation of any mass-spring network. We alleviate the need to solve a linear system through the use of a predictor-corrector approach: We first compute a rapid approximation of the implicit integration, t...

Contact handling is the key of deformable objects simulation, since without it, objects can not interact with their environment nor with the user. In this paper, we propose a novel and very efficient approach for precise computation of contact response between various types of objects commonly used in computer animation. Being constraint based, this method ensures physical correctness, and resp...

Introduction: In brachytherapy, as in external radiotherapy, image-guidance plays an important role. For GYN treatments it is standard to acquire at least CT images and preferably MR images prior to each treatment and to calculate the dose of the day on each set of images. Then, the dose to the target and to the organs at risk (OAR) is calculated with worst case scenario from I...

A fast collision detection and resolution scheme is one of the key components for interactive simulation of deformable objects. It is particularly challenging to reduce the computational cost in collision detection and to achieve the robust treatment at the same time. Since the shape and topology of a deformable object changes continuously unlike the rigid body, an efficient and effective colli...
