Testing the usability of my portfolio:
An eye-tracking study
Skills
Web design, Eye tracking, User ability
Goal
-
Where they are looking.
-
What the ratio of their looking at the crucial information.
-
What parts of the interface they miss.
-
What size and placement of items on my existing site affect attention.
-
Adjusting the most important information to their most focusing place.
​
Design
-
Leave a participant alone during browsing the web page, and therefore capturing real physiological data about their conscious and unconscious experiences.
-
Based on the eye movements of initial version and interviews from participants, I adjusted the structure and front of items.
-
Leave a participant browse the final version to check out the results of design.
Key finding
-
The heat map above shows: Eye movements of the initial version on webpage scatter and participants can not focus on the most important text. However, when changing it to the final version, participants fixated on the most crucial information of pages, and it can be assumed that I achieved the goal of conveying useful message.
-
People see large, bold headlines a lot. Smaller paragraphs and shorter pieces of information are better.
My contribution
-
I abtained the relative intensity of a user’s attention to different parts of my web pages.
-
Eye tracking helps me determine what led to that problem in conjunction with performance data, facilitator observations and user self-reporting.

Goal
Aberrant eye gaze is one of important indicators for autism spectrum disorders (ASD) according to previous studies. However, recent eye tracking studies yield inconsistent findings on whether ASD may pay less attention towards the mouth region compared with typical development (TD) participants.
​
Design
A meta-analysis is conducted with fixation durations on both eyes and mouth regions as dependent variables. And two moderator analysis follow the meta-analysis.
Key finding
-
As project leader, I learned how to instill the main point and convey the vast information with brief words during group meenting.
-
Fixation duration on the eye region is a potential indicator of ASD but the mouth region may not be.
-
Age of autism and whether a face present inversion moderated eye-related fixation duration. And age, verbal IQ, nonverbal IQ , the severity of autism , and task types moderated the effect of experimental manipulation on the mouth-related fixation duration.
-
In order to complete the systematic review, I read hundreds of relative literatures and main textbooks about the development of autism. Through various of face-scanning programs and psychology theories, I found several key moderators can analyze the difference between those inconsistent results.
