最近，触觉的渲染在多媒体和通信领域引起了人们的关注。本研究的重点是热感，这是呈现触觉的重要元素之一。人类通过手感觉物体的运动，如跟踪、抓取和抚摸。为了响应这种移动，有必要考虑系统上接触点的变化。然而，大多数传统的热渲染研究在其系统设计中并没有考虑到这些情况。本研究旨在通过提出一种通过检测单个接触部分来再现热导的控制方法来填补这一空白。在本研究中，将连接在Peltier器件上的铜板视为一个热系统，并将其建模为三个部分。然后将热扰动观测器和热流入观测器分配给每个部件，并且虚拟地再现任何单个部件的热导。此外，在该系统中还引入了单接触部分的检测方法。将检测方法与控制器相结合使得能够根据接触部分呈现不同的热感觉。
The rendering of tactile sensations has recently been attracting attention in the fields of multimedia and communication. This study focuses on thermal sensation, which is one of the important elements for rendering a tactile sensation. Humans feel an object by hand movements such as tracing, grasping, and stroking. In response to such movements, it is necessary to take into account the change in the contacting point on the system. However, most conventional studies on thermal rendering did not take such situations into account in their system design. This study aims to fill this gap by proposing a control method for reproducing thermal conductance with the detection of a single contacting part. In this study, a copper plate attached to a Peltier device is regarded as a thermal system, and the system is modeled with three parts. Heat disturbance observers and heat inflow observers are then allocated to each part, and the thermal conductance at any single part is virtually reproduced. Moreover, a detection method of single contacting part is introduced in the proposed system. Combining the detection method with the controller enables different thermal sensations to be rendered depending on the contacting part.
