| Outline of Final Research Achievements |
For construction a storytelling system in mobile AR environments, we propose a rapid motion retrieval technique to represent motions of characters in stories.
Frames of motions are represented by feature vectors whose elements are integer values. The number of the feature vector dimension is reduced by using the Principal Component Analysis method and values of elements in the vector are quantized into two bits. Comparative experiments with existing methods have proved that our proposed technique can complete retrieval tasks more than 30 times faster than the traditional Dynamic Time Warping method and shown almost the same level of precision and rapid calculation time as existing methods. We also investigated evaluation methods of the proposed system to be used in elementary schools.
