Mobile Application Development to Measure Smartphone Screen Readability

Abstract

This study aimed to develop an application which can be used to measure the
response time needed by subjects to find a set of predetermined “words” in order
to determine the level of readability of smartphone screen. The development
steps began with concept development, interface design and software testing and
verification. The results of this study is a software which can be used for
typography experiment in which the subject is asked to find a predetermined
word. The software could be used for the experiment of 4 typography factors i.e
font style (FS), font size (FZ), contrast (CT), and screen rotation (SR). This
software could be used for the 5x3x2x2 factorial experiment with 60
combinations. The response time of subject for each treatment combination has
been computed and saved in the smartphone. Finally, the response time could
be used to determine the best combination of factor and level factor for
readability of smartphone screen.
