透过窗户的感觉:共时几何和纹理显示的基础上侧向力

Feel through window: Simultaneous geometry and texture display based on lateral force



Satoshi Saga, Ramesh Raskar







概述:



通过触摸屏来显示对象是人机交互的一个研究目标。有研究者采用振动,以便显示纹理信息。然而,没有系统的重新实现,以显示几何形状和纹理。在本研究中,我们提出了一种方法,使用户感觉大的颠簸和精确的纹理,同时通过一个触摸屏。我们的方法采用了侧向力和高频(约1-10KHZ)振动方向控制。振动,正常的手指移动的方向,使独立显示之间的几何andtexture信息。该技术许可可以感受到的不仅geometricalshapes,也包括纹理。

简介:



Recently, touchscreen interfaces have become popular worldwide.Moreover, popular consumer electronics devices such as the iPad(Apple Inc.) use a dedicated touchscreen as an interface. Howeverfew touchscreens enable reactive tactile signals. Furthermore, noneof them provides geometrical shapes and textures simultaneously.Several researchers have employed vibrations to display texture in-formation. For example, [Chubb et al. 2010] developed a tactile display that employs a squeeze film to represent the change in fric-tion. Furthermore, [Wang et al. 2004] have proposed a lateral-force-based sliding systems for displaying texture. In recent years otherlateral-force-based tactile feedback devices that employ static elec-tric fields have been developed (Senseg, Inc., [Bau et al. 2010]).Other studies have used recorded vibrations. [Romano and Kuchenbecker 2012] employed accelerometers, touchscreen and force sen-sors. By recording the information, they display adequate vibrationfor current movement of the stylus. Some of these vibration stimu-lations are realistic; however, they do not provide any geometricalinformation to display.In this research, we propose a method of feeling both large bumpsand small textures simultaneously on a screen. Our method em-ploys lateral force and high frequency direction-controlled vibra-tion. The technology allows not only geometry information to befelt, but also texture information. In addition this technology couldbe implemented in the other lateral-force-based devices mentioned above. By employing the technology, our daily life more tactile one. It enhances experiences of internet shopping, television pro-grams or tele-communications. You can feel teddy bears, clothes,and even your pets through the screen.
