The document summarizes a study on eyetracking-based experiential transcoding of web pages for mobile users. The study found that while participants performed better with transcoded pages designed for mobile, old habits from using standard pages on small screens died hard. Participants still expected similar desktop-style support on their phones, though they were dissatisfied with normal browsing. The researchers concluded that more individualized transcoding may be needed but requires further investigation.

Experiential Transcoding…
• Experiential transcoding aims to transcode web pages into
more accessible forms based on the understanding of
user’s experience.
• Focus on eyetracking based experiential transcoding.
• Improve interaction of disabled and mobile web users.
• What is the effect?

3. 3/11
Findings!
• Even though our participants performed better with
transcoded web pages, our study shows that “old habits
die hard”!
• Although people are not satisfied with their current small
screen device web browsing support, they still manage to
use it and look for similar support in transcoded versions.

User Study Details…
• Hypothesis
– Participants who performed tasks on transcoded pages are more
satisfied with their performance and system, in terms of task
completion, system usability, information quality and interface
quality.
• Materials
– Six web pages in 3 complexity group: apple, babylon, yahoo, avg,
godaddy and BBC.
• Measurement
– Used the After-Scenario Questionnaire (ASQ);
– The Post-Study System Usability Questionnaire: system usefulness
(SYSUSE), information quality (INFOQUAL) and interface quality
(INTERQUAL).
• Procedure
– Task based: Browsing tasks and searching tasks

Summary and Future Work
• Even though our participants performed better with
transcoded web pages, our study shows that “old habits
die hard”!
• Although people are not satisfied with their current small
screen device web browsing support, they still manage to
use it and look for similar support in transcoded versions.
• A more individualised transcoding might be better - need
to investigate further!
