I work at a University where we plan to use a digital pen for an exam. We would very much like to ensure that students don't switch pens. Elaboration: We have a number of identical pens (Nokia) and would like to make sure that each pen can be used on one single computer only. The pens each have a unique pen ID and possibly serial nr. that is can be read by software (the software control panel of the pen does this).
Question 1: Do you know of any existing software that might accomplish this task?
Question 2: If not, what available tools and SDKs are the for the Digital Pen? I only managed to find the anoto stuff which appears very expensive (1000$+). And where might I find protocol / other specs for the pen allowing me to code the stuff myself.
thank you very much for your help - any comments regarding the problem are very welcome :-)
