Abstract

One of the new computational frameworks is physical reservoir computing. Focusing on this method, we have previously developed a soft-matter artificial mouth ”Gel Biter”, which is composed of multiple polymeric materials based on the structure of the human oral cavity. This soft machine can discriminate even subtle differences in food texture with high accuracy. In general, chewing speed differs from person to person. Then, we focus on the result that brittle foods tend to be chewed faster or more finely based on sensory evaluation in some cognitive studies. This study has analyzed the accuracy of the Gel Biter by changing the parameters of its robotic arm and the differences in food texture perceived when the chewing speed is changed. As a result, there is no significant difference in discrimination accuracy for each speed. The cluster analysis shows that the food characteristics are captured and classified. In addition, the estimation results for Fast chewing indicate that the mechanical mouth also generates the illusion that humans perceive different food textures.

凝胶咬器是否会因为咀嚼速度的不同而产生食物质感感知的错觉?
物理油藏计算是一种新的计算框架。针对这种方法,我们之前开发了一种软物质人工口腔“凝胶咬人器”,它是基于人类口腔结构由多种聚合物材料组成的。这种软性机器甚至可以分辨出食物质地的细微差别,准确率很高。一般来说,咀嚼速度因人而异。然后,我们将重点放在一些认知研究中基于感官评价的脆性食物往往咀嚼得更快或更细的结果上。本研究通过改变凝胶咬人器机械臂的参数,以及改变咀嚼速度时感知到的食物质地的差异,分析了凝胶咬人器的准确性。结果表明,不同速度下的识别精度无显著差异。聚类分析表明,食物特征被捕获并分类。此外,快速咀嚼的估计结果表明,机械嘴也会产生人类感知不同食物质地的错觉。
