Hi out there, I am not sure whether this is the right forum, so sorry in advance if not. But I saw some questions regarding eye tracking so I hope you could help me. - BTW do you know forums that are completely dedicated to eye tracking?
Okay, here is my challenge: I am working since two years with eye tracking in the context of dialogue systems. Currently I try to build a system which displays information for several objects (e.g. buildings, touristic info etc.) and tries to recognize (via eye tracking) whether the user has enough information displayed on the screen or whether he/she is seeking for additional information somehow. So my question is: Is there a way to determine this by simply ana- lysing the properties of the scanpath (measuring angles between saccades, transition densitiy for directness of search, or even better because simpler solely fixation length or saccadic amplitude) without the underlying stimulus (making AOIs and such)? The user wears a head mounted eye tracker (SMI iViewX) and watches the information on a large screen. Interaction is usual mouse interaction, clicking on objects for getting context information about them. I know there's much about reading research, so ones maybe could distinguish whether the person is reading something. But I think also need to distinguish whether the person is somewhat relaxed because he/she is content and has enough information or whether he/she is seeking for something. Maybe pupillometric data could help here additionally, but I would be happy not having to base the system on pupillometric data because I have no experience with that and don't know how robust that would be. If anyone of you had some ideas how to do this or some hints where to further read (papers, names of persons who do research with that) I would be very thankful. Thank you in advance and hopefully see you some day. Best regards, Peter. ________________________________________________________________ *Come to IxDA Interaction08 | Savannah* February 8-10, 2008 in Savannah, GA, USA Register today: http://interaction08.ixda.org/ ________________________________________________________________ Welcome to the Interaction Design Association (IxDA)!
