本章介绍了我们利用混合现实（MR）技术对视觉/触觉刺激融合的感官特性进行的实验研究。我们特别关注两种刺激之间的差异。当我们在电视或网上购物时，我们有时会因为产品的实际尺寸和材料与我们的形象不同而感到失望，即使它的外观最初给我们留下了深刻的印象。这个案例表明，使用综合的多种感官线索，不仅包括视觉，还包括听觉和触觉，以提取物体的属性。然而，通过相互作用的多种感觉线索的融合尚未得到很好的研究。本文介绍了我们开发的独立控制视觉和触觉线索敏感性参数的系统，以研究这些线索对感官特性的影响。磁共振技术已应用于工厂，以协助组装，检查和维护操作（Ohta和Tamura， 1999年）（Wiedenmaier等，2001年）（Friedrich， 2002年）（Fiorentino等，2002年）（Nolle和Klinker， 2006年）。最近，工业产品的设计操作作为下一代磁共振应用（Navab, 2003） （Lee & Park, 2005） （Sandor et al, 2007）正在引起人们的关注。在普通的设计操作中，首先，设计师使用计算机辅助设计（CAD）系统开发形状，外观和内部结构的广泛绘图。然后生成一个模型（mock-up），即设计产品的虚拟模型，以检查CAD难以表示的触觉和表面纹理等详细信息。然而，生成一个模型是非常昂贵的，特别是因为它使用临时资源。因此，每当设计有微小的变化时，重新生成模型是不现实的。图1所示的显示系统可能会创建一种新的产品设计风格，以减少操作流程。例如，在普通的产品设计中，当设计师想要评估由于表面材料的细微变化而引起的不同印象时，就必须生成与每一个变化相对应的许多相似的预生产样品。然而，设计变化通常是有限的，因为它们太昂贵了。另一方面，使用我们提出的系统，可以通过将各种外观的计算机图形（CG）纹理叠加到设计模型上进行评估，这不仅解决了成本问题，还解决了试验设计变化的局限性。30.
This chapter introduces our experimental investigation about sensory properties in the fusion of visual/haptic stimuli by using Mixed-Reality (MR) technique. Especially, we focus on the discrepancy between the two stimuli. When making a purchase from TV or online, we are sometimes disappointed by a product whose actual scale and material differ from our image, even though its appearance originally impressed us. This case indicates the use of integrated multiple sensory cues that include not only the visual but also the auditory and haptic to extract the properties of objects. However, the fusion of multiple sensory cues by interaction with each other has not been well examined. We introduce our developed system that can independently control the sensibility parameters of visual and haptic cues to study the effect of these cues on sensory properties. MR techniques have been applied in factories to assist assembly, inspection and maintenance operations (Ohta & Tamura, 1999) (Wiedenmaier, et al, 2001) (Friedrich, 2002) (Fiorentino et al, 2002) (Nolle & Klinker, 2006). Recently, designing operations for industrial products are gathering attention as the next generation of MR applications (Navab, 2003) (Lee & Park, 2005) (Sandor et al, 2007). In ordinary designing operations, first, designers develop a broad plot of shape, appearance, and inner structure using a Computer Aided Design (CAD) system. After that, a mock-up, which is a dummy model of the designing product, is generated to examine such detailed information as a sense of touch and surface texture that is difficult to represent by CAD. However, generating a mock-up is very expensive, especially since it uses temporal resources. Thus, it is not practical to regenerate a mock-up whenever a design receives a minor change. The display system shown in Figure 1 might create a new style of product design to reduce operation processes. For example, in ordinary product design, when a designer wants to evaluate different impressions caused by subtle changes of surface material, many similar preproduction samples must be generated that correspond to each change. However, design variations are usually limited because they are too expensive. On the other hand, using our proposed system, evaluation is possible by superimposing computer graphics (CG) textures of various appearances onto a design mock-up that solves not only cost problems but also the limitations of trial design variations. 30
