Andrew
DeVigal outlines some of the preliminary findings
and observations of the Stanford Poynter Eye-Track
Research study. Final results are expected at
the beginning of 2000, he says.
I.
Where Eye-Tracking Ranks in Research
A.
Online Survey
B.
Log Tracking
C.
Focus Groups & Survey
D. Eye Tracking & Post Questionnaire
II.
The Stanford Poynter Project: Eye-Track Research
collaborative study between The Poynter Institute,
Stanford University's Department of Communications,
and the Center for the Study of Language and Information
(CSLI). The Stanford researchers are Marion Lewenstein
of the Department of Communications; Greg Edwards,
the project leader for the Advanced Eye Interpretation
Project, of CSLI; and Deborah Tatar, a research
associate.
A. Subject Recruitment & Criteria
1. Subjects are recruited through a
news brief and an article published in the
local newspaper's website and print edition.
San Jose Mercury News in California, the St.
Petersburg Times in the Tampa Bay Area, and
the Chicago Sun Times in Chicago.
2. Subjects must read online news at
least three times a week.
3. Those with bifocals, or those who
experience constant migraines or are susceptible
to seizures, are prescreened.
4. The task: simulate a single session
of their reading/browsing online news.
B. Statistics & Logistics
1.
Three city/region study: Northern California,
Tampa Bay Area, and Chicago.
2. 25-30 subjects per city, though
we will go through 35 to 40 interviews to
get 25 to 30 usable subject.
C. Computer Setup
1. Computer browsing with Communicator
4.0 or Internet Explorer 4.0 connected to
a T1 line. Monitor set to 800x600.
2. Subjects are asked to bring a disk
copy of their bookmarks, or a list of bookmarks
or asked to simply type in their URLs.
3. Standard plug-ins such as RealAudio,
Shockwave, and Flash are preinstalled.
4. The Eye Tracker.
D.
Software
The software included the Eye Tracker machine's
EyeLink software, which tracked the eye movements
of the subjects and Greg Edwards' proprietary
software, which has three main features:
1. Capture Software (automated):
a. Captures eye movements and deciphers
patterns such as reading, searching, and
scanning.
b. Captures the entire screen every
five seconds and every instance of a mouse
click, an arrow key, page up, and page down.
c. Captures a small thumbnail of
the eye's focus every fraction of a second.
d. Captures time.
2. Describer Software: A coding tool
that allows a researcher to define elements
of the web page.
a. Define the state of the screen
(the launch of a browser and a change to
a different news provider).
b. Define the elements of the screen
such as the Windows tool bar, the browser's
chrome, and active space.
c. Define the elements of a web page.
d. Define the content (news, sports,
features, breaking news, etc.).
3. Analyzer Software: Once all areas
are defined, the data is sent to an SQL (Structured
Query Language) database where we can ask
questions referencing across several levels
of information at once. [Examples expressed
in sentence].
a. (easy) How much time was spent
reading in proportion to total time?
b. (medium) What are the content
types of briefs that were read and clicked
on to get the full story?
E.
The Process
1. Respond to online and print promotion
by e-mail.
2. Prescreening to qualify for the
study by telephone interview.
3. Fill out demographic sheet at study
location.
4. Eye Tracker is setup.
5. Subjects read/browse their online
news while being observed by a researcher
and video taped.
6. Post questionnaire qualifying some
behavior based on observations.
III. First Tentative Report from Marion Lewenstein,
based on preliminary research study before the
start of the official Stanford-Poynter Project.
Here are some highlights that we have found consistent
through current observational-only data
A.
Interweave news sites: most people interlaced
between sites, moving back and forth between
them by topic, often times comparing or getting
more information. In addition, many wanted to
read more on items they had read, heard, or
seen earlier in newspapers, radio, or TV.
B. Checking the news throughout the day:
many people would "dip" into their
online news sources in the morning and then
return to them in the afternoon and evening.
C. Familiarity: Subjects commented often
that they had bookmarked newspaper sites from
places where they had formerly lived or where
they still had relatives.
D. Customized news: A few (1/3 in the
original study) subjects customize their online
news sites. However, they always moved on to
general news sites, specifically commenting
that they want to stay well informed on many
subjects.
