2 2/11 “Experiential Transcoding” “It differs from plain content transcoding because it is user centred and includes techniques that transcode web pages based on understanding and predicting users’ experience!”

3 3/11 How? For experiential transcoding, we need to be able to understand and predict users’ needs and requirements but how can we do this? We user eyetracking data but we can possibly use: –Log data on servers? –User’s interaction patterns? –Coping strategies? –Mining daily activities, etc.

4 4/11 Eyetracking Approach Eyetracking studies generate enormous amount of data! –Scanpaths are repetitive sequences of fixations and saccades that occur upon a visual stimulus. In our project, called eMine (http://emine.ncc.metu.edu.tr/), –mines the eye tracking data to identify scanpaths and –relate them to visual elements of web pages and the underlying source code –web pages can be transcoded to provide better user experience to disabled and mobile web users.

5 5/11 1: Segmentation

6 6/11 2: Eyetracking in terms of Visual Elements Example scanpath: ABCBDCACACBEBDEBE

7 7/ Patterns in Scanpaths: Existing Work Limitations of existing work: –Reductionist –Ignore complexity of cognitive processes –Eliminating noisy data –Simple inputs

8 8/ Patterns in Scanpaths: Our Approach

9 9/11 Resulting Scanpath

10 10/11 Future Work What are the possible experiential transcoding techniques? Other than eyetracking data, what could be the possible driving input for experiential transcoding? How can we generalise experiential transcoding?

11 11/11 Thanks! Further information: –http://emine.ncc.metu.edu.tr/ –http://wel-eprints.cs.manchester.ac.uk/154/ Thanks to: –The Scientific and Technological Research Council of Turkey (TUBITAK) Contacts: –Yeliz –Simon Harper, Thank you for your questions!
