written in the space below the pre-printed character, and each text was written on a separate page with the template text printed in the upper part of the page. during writing, the online data (stroke trajectory: sequences of (x,y) coordinates) were recorded by the anoto pen and later transmitted to computers. <h3>online data examples</h3> <img src="source/image12.jpg" width=437 height=302> (a)
