Recognizing arbitrarily connected and superimposed handwritten numerals in intangible writing interfaces
作者：
Highlights：
• An intangible writing interface recognizes mid-air gesture trajectories of numerals.
• A key numeral spotting method locates any specific numeral within a gesture trajectory.
• A recognition by concatenation method recognizes connected numerals without using lexical dependency.
• The method achieves good performance without extracting sophisticated character features.
