User Tracking at Smart Desk.

   Here, the user tracking methods at SD are described and classified into two types, client side and server side methods. As for the client side methods, basic idea is to measure "events" which are generated by users along with "time" information. (Discrete Event System) To measure and analysis had been tried at Java applets. By using NeatTools software, event recording of non-java application was performed, but the data analysis was not tried.(table 1) Server side methods are the ones described in my previous thesis draft. Web log of a user's learning session was analyzed "quantitatively."  Total data transferred, number of hits(requets from client to server) during the learning session, and completion time were mainly compared among original SD and personalized SDs in terms of size of environments , including discussion about adaptiveness issues.

  Tracked Info Analysis
Applets Number of mouse clicks, time and objects information, mouse trajectory(x and y coordinates, sep.), right/wrong answers(percentage and numbers), replay, options, verbal description(crude data)  Yes
other application Mouse clicks and movements are recorded and replayed by a local process(programmed in NeatTools module) at a client machine. No*

* The recorder object generates a text file which is not legible by itself but contains certain time information and basic type of inputs. It can be analyzed to show when a user changed type of inputs. If necessary, I will analyze the data file.
