「HapMAP」は手すりを伝う感覚による触覚ナビゲーションデバイスです。”視線や意識が手元に集中してしまう” ”会話や音楽、都市のサウンドを楽しめない”ナビゲーションによる視覚・聴覚の制限は都市経験を損なわせます。直感的でナチュラルなインターフェース、カーブの詳細まで誘導可能な性能、シンプルな構造により、都市を楽しむ上で必要な感覚を損なうことなく目的地へと誘導します。

Techtile Toolkit

"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.

「TECHTILE toolkit」は、触感を用いた表現のためのラピッドプロトタイピングツールです。研究者・技術者のみならず、デザイナー・アーティスト・教育者・学生・子供など、前提知識なしに誰でも手軽に触感を使った作品やシステムを試作することができます。触感の記録と再生に音響信号を用いることで、既存のプラットフォームをそのまま活用して触感の取得・編集・伝送が行なえます。

Rhino AR

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.

Adaptive Parallax 3D LED display

"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.
