Drawing on Paper Maps: Reliable On-line Symbol Recognition of Handwritten Symbols Using a Digital Pen and a Mobile Phone

We present a reliable on-line handwritten recognition system which recognizes symbols, such as NATO symbols, drawn on a paper maps using a digital pen and a mobile phone. Our user evaluation shows that maximal accuracy can be achieved. Furthermore, our proposed system has low latency running on off-the-shelf mobile phones. The recognition system is part of a research effort providing field soldiers with lightweight computer support.
