Letter Reaction Time

Compare the legibility of different typefaces.

1. A random term appears on the screen.
2. The tester needs to recognize the part of speech of the term by tapping V or N.
3. The app records the response time and correctness of the answer.

Features (For Researchers)

Researchers can configure typefaces and terms used in the app.

1. Add more terms in VocabSources.plist.
2. Add more typefaces in FontDescriptions.plist (can be more than 2).

The app will output a plist file after a test.

How to Use (For Testers)

• Press V if the term displayed on the screen is a verb.
• Press N if the term displayed on the screen is a noun.
• Press B to continue.
