In this paper, we propose a therapeutic-assisted robot for children with autism to ameliorate their skill of joint attention. The robot conducts a goal-directed based interaction to establish engagement between the child and robot in order to establish a beneficial learning environment for autistic children. An unsupervised Mixture Gaussian-based cluster(More)
Robust manipulation of a geometric model, that is free from computational errors, is one of the difficult prohIems in geometric modeling, and its algorithm is not established especially for the boundary representation. This paper proposes a new face-based data structure and a robust algorithm for processing polyhedra represented in the data structure. The(More)
In this paper, we propose a method which modifies free-form surfaces to pass through not only specified points but also specified curves with the assistance of haptic navigation. Using the method, designers of aesthetic shapes such as a car body can manipulate the model of the shape in real-time looking at its stereoscopic image and feeling its haptic(More)
In order to robustly perform segmentation for industrial design objects measured by a 3-D scanning device, we propose a new method for high-quality vertex clustering on a noisy mesh. Using Student-t mixture model with the variational Bayes approximation, we develop a vertex clustering algorithm in the 9-D space composed of three kinds of principal(More)
