Quantitative Analyses on Effects from Constraints in Air-Writing
Songbin Xu, Xue Yang, Yuqing CHEN · IEICE Transactions on Information and Systems · 2019
Very few existing works about inertial sensor based air-writing focused on writing constraints' effects on recognition performance. We proposed a LSTM-based system and made several quantitative analyses under different constraints settings against CHMM, DTW-AP and CNN. The proposed system shows its advantages in accuracy, real-time performance and flexibility.
