We are investigating the
user response to Microsoft's ClearType font enhacement technology.
ClearType is a setting that is manipulated through the operating system of devices using
Liquid Crystal Display screens. ClearType works by altering the vertical color stripe within a pixel,
allowing for changes in how the text looks at fractional levels. These changes are intended to enhance
the resolution of the screen text and improve readability.

Regular text (without ClearType)
Spring 2006 Update
The results from Study 3 will be presented at CHI 2006 (Montreal, April 22-27).
Here's the unofficial version of the CHI 2006 paper (after April 27, 2006 please cite and use the copy available from ACM's Digital Library):
Since Study 3, we've collected and analyzed data on how users transition back-and-forth between ClearType and regular text. Further results on our ClearType work will be published later this year in a comprehensive article.
In Study 1 we looked at
whether individuals have a preference for choosing ClearType text when
given a choice of three different font styles--some of which had ClearType, and others that were
just regular text. We found that people selected text with ClearType 80% of the time.
In Study 2, we investigated
user behavior as participants completed standard everyday office tasks
(with either ClearType on or off) such as editing a Word document, scanning an Excel spreadsheet,
and reading an on line article. When ClearType was present, participants read from a computer screen
approximately 30 seconds faster.
In Study 3 we followed up on the results of Study 2 by examining separately the scanning and reading tasks.
In this report, we find continued support that on average, users perform tasks faster with ClearType.
