"The TECHTILE toolkit" aims to be an easy-to-use content production environment to create haptic content. This device utilizes audio signals to produce tactile vibration that enables to record, playback and even edit vibratory signals using audio authoring software." The TECHTILE toolkit" is useful for creating haptic signals for designers and artists in their creation, teachers and kids in science workshop, and haptics researchers in basic psychological study.
A design of product is an important factor in producing a new product. Product designers create three-dimensional computer-graphics (3DCG) models by the use of 3DCG modeling tools and make mock-ups to review their designs. However, there are differences of aspects between the original 3D models and the generated mock-ups frequently. Moreover, it takes expenses and long development terms to re-create new designs and mock-ups for desired products.
In this paper, we propose a system in that a user can create and check virtual mock-ups while creating 3D models of products. We construct the system by combining a commercial 3DCG modeling tool with an augmented reality (AR) technology, and 3DCG models are superimposed on the real-world environment in real time during their modeling process. Furthermore, 3DCG models are displayed with real scale and natural illumination on a see-through display. Therefore, the system enables product designers to review designs of new products without making real mock-ups.
We collaborated with Technology Joint Co. for commercialization of the proposed system. We developed an original AR function to display real scale 3DCG models and illuminate them naturally on real space. Moreover, we verified the effect of the proposed system for reviewing designs of 3DCG models in detail without making real mock-ups.
"Autostereoscopic 3D displays" using static parallax barrier or lenticular lens are commercially available in these days. In these methods, however, the number of viewpoints is fixed at the time of manufacturing. Active parallax barrier [Perlin, 2000] and dynamic parallax barrier [Peterka, 2008] have been proposed to improve the resolution and number of viewpoints by moving the position of the parallax barriers. To implement an autostereoscopic display, with dynamic parallax barriers, dual-layered LCD panel is a common approach as is mentioned by [Hirsch, 2010]. And a method of optimizing the parallax barriers [Lanman, 2010] has been proposed to represent more perceptually-acceptable imagery. Remaining limitations of the dual-layered LCD method are the refresh rate and brightness of the LCD panel. Commonly used high-speed LCD has 120Hz in refresh rate and around 500cd/m2 in brightness so that conventional systems did not have enough quality to be used in public. To solve this problem, we propose an adaptive parallax autostereoscopic display composed of a high-density/high-frequency LED panel and a high-speed/high-contrast LCD panel.
