This would ideally be done in C# and is intended for larger form factors (NOT mobiles.).
I'm a novice in this area, but would users suggest Silverlight (Can it process touch screens?) or WPF or are other technologies better?
Ideally this would involve users tracing shapes with their fingers or a stylus, and the system automatically marking it.
My background is .net/c# web development. Thanks
