3D Haptic modeling system using ungrounded pen-shaped kinesthetic display
ABSTRACT We propose a three-dimensional (3D) haptic modeling system that enables a user to create 3D models as though he/she is drawing pictures in mid-air and touch the created models. In the proposed system, we use our ungrounded pen-shaped kinesthetic display as the interface. The kinesthetic display device can generate kinesthetic sensations on the user's fingers. Because our system does not use mechanical linkages, the user can freely move his/her hand and feel the sensation of touching virtual objects. In the proposed system, the user can easily and intuitively create various 3D shapes by drawing closed curves in air using the device. The created shapes are generated in a physics-based simulation environment and are displayed as 3D images. Therefore, the user can touch and see the drawn shapes as though they exist in reality.

ABSTRACT: The usage of Nvidia 3D Vision® is increasing rapidly, ranging from gaming to research purposes. However, researchers in human computer interaction and virtual reality are constrained by hardware configuration since current com-mercial gaze tracking systems are not specifically designed to be used with Nvidia 3D Vision®. In this paper, we present a novel prototype of gaze tracking headgear which can be used appropriately with Nvidia 3D Vision® . We explain design consideration and detail implementation of our gaze tracking headgear. We also evaluate our gaze tracking system by measuring gaze accuracy on stereoscopic display. Experimental result shows that the average gaze estimation error is less than one degree visual angle.Conference Proceeding: ...

ABSTRACT: Inappropriate parallax setting in stereoscopic content generally causes visual fatigue and visual discomfort. To optimize three dimensional (3D) effects in stereoscopic content by taking into account health issue, understanding how user gazes at 3D direction in virtual space is currently an important research topic. In this paper, we report the study of developing a novel 3D gaze tracking system for Nvidia 3D Vision® to be used in desktop stereoscopic display. We suggest an optimized geometric method to accurately measure the position of virtual 3D object. Our experimental result shows that the proposed system achieved better accuracy compared to conventional geometric method by average errors 0.83 cm, 0.87 cm, and 1.06 cm in X, Y, and Z dimensions, respectively.Conference proceedings: ...
