项目摘要

The researchers have constructed a prototype system through production and evaluation of cross-modal contents for specific situations, focusing on the characteristics of human brain function. Multiple approaches were used in developing cross-modal contents within the range of synesthetic cross-modal representation.As specific content production, production of virtual reality (VR) content for safety education utilizing the induction of body image was created. A survey was performed to examine the possibility of practical application, and content development for various cognitive statuses was suggested from the results.As the evaluation method for cognitive experience that involves obtaining the participant's body image in a virtual space, a brain function measurement technique, near infrared spectroscopy (NIRS), was used to examine whether objective evaluation is possible. The results indicated that the induction of body image could be evaluated by observing specific brain regions. The method of analysis of data obtained through brain function measurement was also examined, and the researchers were able to remove noise through trend analysis.During examination regarding induction of body image, the researchers showed that by applying visual and tactile cross-modal stimulation, an illusion of haptic movement is perceived, which is different from what is presented. The researchers evaluated this illusion, and found a relationship between subjective evaluation and NIRS data results. In addition, the researchers examined this synesthetic phenomenon causing a sense of touch that is not actually presented to the participant The results from NIRS data indicated the presence of a synesthetic experience. From the results of this research, the researchers obtained many specific and useful findings. These results will contribute to the development of core technology that may facilitate the future development of new types of media content.

研究人员围绕人类大脑功能的特点，通过对特定情境下的跨模态内容的生成和评估，构建了一个原型系统。在联觉跨模态表征范围内，采用了多种方法来开发跨模态内容。作为具体的内容生产，创造了利用身体形象诱导的安全教育虚拟现实（VR）内容生产。通过调查，探讨了实际应用的可能性，并根据调查结果提出了针对不同认知状态的内容开发建议。作为认知体验的评估方法，需要在虚拟空间中获得参与者的身体图像，因此使用近红外光谱（NIRS）脑功能测量技术来检验是否可能进行客观评估。结果表明，身体形象的诱导可以通过观察特定的大脑区域来评估。研究人员还研究了通过脑功能测量获得的数据的分析方法，并通过趋势分析消除了噪声。在身体形象诱导的检查中，研究者发现通过视觉和触觉的交叉模态刺激，可以感知到一种与所呈现的不同的触觉运动错觉。研究人员评估了这种错觉，并发现了主观评价与近红外光谱数据结果之间的关系。此外，研究人员还检查了这种导致触觉的联觉现象，这种感觉实际上并没有呈现给参与者。近红外光谱数据的结果表明，联觉体验的存在。从这项研究的结果中，研究人员获得了许多具体而有用的发现。这些结果将有助于核心技术的发展，这可能有助于未来新型媒体内容的发展。
