FontsApp-Eye-Tracker

SPECIFICATION OF THE APP

The app may be called the “Fonts” app.

Objective of the app is to determine for (a) typeface, (b) font size and (c) line spacing that a child finds easy to read from the screen of a smartphone.

--> FIRST SCREEN

The app allows the user to select typeface, font size and line spacing. Three dropdown menus will be used.

Typefaces:

  • Arial
  • Sassoon Primary
  • Times New Roman
  • Bodoni MT

Font size:

  • 12
  • 14
  • 16

Line spacing:

  • 1
  • 1.5

There should be a “Next” button at the bottom of the first screen.


--> **SECOND SCREEN**

  • The app will display a paragraph of text with 100 to 110 words.

  • The app will have 24 paragraphs which will be used randomly with different combinations of typeface, font size and line spacing.

  • The selected typeface, font size and line spacing will be used.

  • Portrait orientation will be used.

  • Vertical scrollbar will be used if necessary for any combination.

  • However, the reading area will be the same for all combinations.

  • There will be three buttons at the bottom of the screen which will be always visible, viz. “Start”, “Stop” and “Next”.

  • The observer will press the Start button and the child will start reading the paragraph.

  • When the child ends, the observer will press the Stop button.

  • All observations will be made during this period only.


THIRD SCREEN

  • The app will show the following results:
  • Reading time (in milliseconds)
  • Number of eye fixations
  • Cumulative eye fixation duration (in milliseconds)

At the bottom, there will be a button “Another Trial” which will take the user to the first screen.
