Cross-Field Haptics

Abstract :
The representation of texture is a major concern during fabrication and manufacture in many industries. Although it is easy to change the texture of objects in the digital world (i.e. just setting texture parameters), it is difficult to achieve this in the real world. Tactile feedback allows displaying texture and affordance. In conventional research, a single physical quantity is used to render haptic textures. In contrast, Our proposed system physically deforms and changes the physical force between the finger and the device. To achieve this, we combine magnetic and electrostatic fields.We use ferrofluid which is flexible liquid from the magnetic field, and electrovibration with adsorption force from the electrostatic field to develop this device.

テクスチャの表現は多くの製造産業においてよく議論される問題である。しかし、現実世界のテクスチャを変化させることはデジタル世界に比べて難しい。触覚フィードバックという技術はテクスチャやアフォーダンスの提示を可能にすることができる。従来の研究では、単一の物理場のみを使用しテクスチャレンダリングをしている。一方で私達の提案するシステムは、指とデバイスの間の形状や抵抗力を変化させる。そのために、磁場と電場を組み合わせた。磁場からは磁性流体のフレキシブルな柔軟性、電場からは静電吸着の抵抗力を使用した。
