| Outline of Final Research Achievements |
A Wearable HandWriting Recognition (WHWR) System is developed.
1. Through continuous testing on the prototypes of the WHWR sensor node, we have successfully developed a tiny size wearable sensor node. Moreover, the powering issues, which arose from the deployment constrains on the finger nail, have been solved as well. 2. A database for the handwriting data management is developed, together with a visualization function of the data waveforms and the 3D demonstration on the handwriting trajectory, which greatly improve the efficiency of the data analysis. 3. DTW (CDP) is adopted for the segmentation on the continuous handwriting and kernal SVM is adopted for the handwriting characters recognition, which accuracy is about 97% on a 10 digits data set.

申請者はICDAR17に提案したウェアラブル手書き認識方式（WHWR）を指先に付けられる手書き動作記録装置、およびそれに適用できる認識手法の研究開発によって、発展させました。
「筆記」は、空間と時代を超えて、人間同士がコミュニケーションするために欠かせない手段である。 WHWRは既存の手書き認識手法と比べて、任意のペン、あるいは指だけで、自由なスペースで入力できること、さらに、アナログおよびデジタルの情報を同時に記録できることが独自の優れた特徴である。WHWRを発展させ、筆記データのシームレスなデジタル化を実現し、新たな筆記方式の創出に貢献することが期待できる。
