项目摘要

This project has been developing tactile feedback techniques that can present realistic and assistive tactile information in a virtual manipulation space to improve the usability and the design of touch panel based handheld devices. The virtual manipulation space is developed so that the users can experience a realistic operation through the tactile information given to their fingers while they are manipulating the virtual handheld devices. The system consists of sensors to detect finger movement and actuators to generate the tactile information. The tactile information takes the form of force or displacement. And, with the tactile feedback generated by the actuators, the users can feel the repulsive force and the friction against their operation. The stiffness, the texture and the 3D shape of the touching surface can be also represented by displacement of the touch surface moved by the actuators. The proposed techniques are applied to the touch panel based devices such as the smart phones or the tablets. With the tactile information generated by the proposed techniques, the computer aided design can deal with the aspects concerning touch in addition to the conventional shape. And the usability of the touch panel based user interface is shown to be improved. The time consuming process of prototyping would be improved as the design concerning the shape and the touch can be conducted in the virtual space. In order to improve the responsivity of the tactile feedback and simplify the system, we also introduced passive tactile feedback devices and evaluated their effectiveness by making many prototypes.

本计画致力于开发触觉回馈技术，使触觉回馈技术能在虚拟操作空间中呈现真实且具辅助性的触觉资讯，以提升触控面板式手持装置的使用性与设计。开发虚拟操纵空间，使得用户在操纵虚拟手持设备时可以通过给予他们的手指的触觉信息来体验逼真的操作。该系统由传感器来检测手指的运动和执行器产生的触觉信息。触觉信息采取力或位移的形式。并且，通过致动器产生的触觉反馈，用户可以感受到对其操作的排斥力和摩擦力。触摸表面的刚度、纹理和3D形状也可以由致动器移动的触摸表面的位移来表示。所提出的技术被应用于基于触摸面板的设备，诸如智能电话或平板电脑。利用所提出的技术产生的触觉信息，计算机辅助设计可以处理除了传统形状之外的与触觉有关的方面。基于触摸屏的用户界面的可用性得到了改善。由于可以在虚拟空间中进行有关形状和触觉的设计，因此可以改善原型制作的耗时过程。为了提高触觉反馈的响应度和简化系统，我们还引入了被动触觉反馈装置，并通过制作许多原型来评估它们的有效性。
