| 概要 |
We propose a haptic database retrieval system based on user’s perception and media converter that translates it into a physical haptic feedback. We have developed a three-dimensional psychological spa...ce that expresses human perception haptic stimuli by using semantic differential pairs. Differential Evolution (DE) algorithm searches and retrieves haptic stimuli within a haptic physical feature space. Moreover, Neural Networks (NN) maps the searched physical feature vectors into the psychological space. The distance between the mapped positions and target position in the psychological space is used for the GA search, and when the distance becomes less than the threshold value, the retrieval search ends. In this study, we have conducted a preliminary experiment to construct psychological space and the NN part of the proposed system. The result of the preliminary experiment and the configuration of the NN will be discussed in detail.続きを見る
