Summary:
MCSig, a system designed with multimodal feedback for aiding visually-impaired people in learning to write. Unlike ordinary people, visually-impaired people lack the main form of feedback while writing - the visual feedback. This makes their learning harder. This paper proposes a tool which combines haptics and feedback through sound to help write the characters. A specially designed tool is being used in this tool to guide the user to trace through the character and a sound based feedback to get a feedback on the quality of the trace.
Discussion:
This paper throws interesting aspect of feedback to people. Using ridges on the paper to provide feedback on shapes is an interesting method.
This paper also shows the way we learn to write.
- First we start learning by tracing over the character. This means moving our whole hand and the pen together to trace the whole character. As the pen traces the character, hand also traces the character. This is the also the way we start writing in the cursive.
- As our confidence grows, we fix our palm and trace the characters by moving the pen and the 2 fingers holding our pen.

I liked your discussion on tracing in relation to learning a shape or character. There is a lot of intention put into tracing or overtracing: learning the shape? making it bold? emphasizing it? creative shading?
Interesting paper on feedback and good discussion of how we learn to write and draw and how our confidence changes the way we draw. The information like tilt can help us distinguish between the drawing of learned sketch or not learned sketch if not between text and shape.
