What is Tibi

Tibi is an Open Source handwriting recognition system focused on Chinese charateres. Tibi is an intended frontend to Chinese dictionaries that speeds up character look up. Further possible applications are hand held devices without a keyboard and the entry of characters without input method, such as chinese radicals or pictographs.

Tibi is an online character recognition system. It uses the stroke order and the stroke direction to determine which character a user has entered. If for instance three strokes are drawn on top of each other a "三" would be recognized, although its visual appearance is indistinguishable from "一". Permutations in stroke order and errors in stroke directions are checked if a character is written clearly and with pen up after every stroke. With correct stroke orders cursive writings is recognized in many cases.
