The human primary somatosensory cortex corresponds to an organized topological map of all body parts (somatotopy). However, the representative proportion of body parts in the brain differs from that of the physical body. This distorted representation is called the cortical homunculus. Body parts with extensive cortical representation have a greater sensitivity in spatial resolution. We have developed the software, Face Homunculus Viewer, that can modify any facial images to homunculus-like faces with sensitivity parameters. The software was employed to support children and adults in understanding the cortical homunculus and the sensitivity differences of various body parts. Several workshops were held in which participants measured two-point discrimination thresholds at the forearm, lip and forehead to create a personalized homunculus. The software may contribute to user knowledge on the mechanisms of somatosensory perception in the brain of humans through their own embodied experience.

In science education, it is crucial to create teaching materials that are directly linked to students' individual experiences. On “The Japanese Psychonomic Society Committee for Developing Teaching Materials for High School Students,” using computer graphics technology, we developed a visualization system called “Face Homunculus Viewer” (FHV) that provides an opportunity for students to gain a deeper understanding of the relationship between brains and minds. Additionally, we conducted a workshop on human touch perception using FHV. In the workshop, we defined the two-point discrimination threshold of touch as “tactile acuity,” and students measured their tactile acuity with the methods used in psychological experiments. Our contributions are the development of an interactive system for visualizing differences in tactile acuities between bodily sites within each individual and differences between individuals. We believe that this study will indicate a new direction in science education in which computer graphics can be applied.
1 0 0 0 OA 聴感評価に基づく雰囲気音制作手法の開発
特にインタラクティブな映像作品制作を想定した効果的な音響デザインの指針を得るために、物理的な「正しさ」よりも聴感上の効果の面から、要素となる音を組み合わせることで狙い通りの効果をもつ雰囲気音(後景となる音)が合成できるか、また、後景となる音や前景となる音がそれぞれその時々の情動状態や他の前景情報の理解にどのような影響を与えるかを検討した。その結果、前者については要素の単なる加算を超えた何らかの直接的な音響的特徴による表現が必要なこと、後者については音がその時々の情動状態や前景となる情報に確かに影響を与え、またその与え方には一定の傾向があることが見いだされた。
