This drawing system beautifies your free hand strokes, and predicts your next drawings.
This applet works only on Microsoft InternetExplorer 4.0 !!

Detailed manual is here.

How to play

• Drawing lines
  • You can draw a free stroke using left button dragging.
  • The system beautifies it when you finish drawing. Red line is the primary candidate, and magenta lines are secondary candidates.
  • You can select another candidate by clicking a magenta candidate.
  • Primary candidate is settled when you click other area then magenta candidates, or you draw the next free stroke.
• Predictions
  • When you settle the primary, the system predicts the next drawings, and shows predicted magenata lines.
  • If you like a predicted line, click it. The system generates next predictions. If not, click somewhere else, or draw a free stroke.
  • If you click on a black line, the system generates predictions around the line.
• Erasing
  • You can erase existing line by drawing scribbling stroke. Note that what is erased is one closest to the starting point of the scribble.
  • You can also erase lines by click-dragging of left botton. (click-drag is similar to double click, but not to release button after the second button down)
• View Control
  • You can scroll screen using right button dragging.
  • You can zoom in/out using right button click-dragging.
• Misc
  • Save/load is not supported. Please use "Print Screen".
