Uses Rembrandt.js as a browser-side library to grade the accuracy of the user's drawing when tracing a kanji. Displays a notification bar containing the user's score, on a scale from 0 to 100, which fades away shortly.
A grading scale relative to the complexity of each character is used. Once the user's drawing is graded against the correct drawing, a blank canvas is also compared against the correct drawing. The final score is then the drawing percentage divided by the blank percentage. Doing this achieves a grading scale relative to the complexity of each kanji, making each grading between kanji more accurate.
