Validation of a Smartphone-Based Flicker Fusion Test
The purpose of this project is to validate a quick, easy-to-use and administer smartphone
flicker fusion test. The app (called eyeFusion) can potentially be used to easily and quickly
collect critical flicker fusion measurements on patients admitted with optic disorders as
part of the clinical care process.
flicker fusion test. The app (called eyeFusion) can potentially be used to easily and quickly
collect critical flicker fusion measurements on patients admitted with optic disorders as
part of the clinical care process.
The smartphone app developed is a flicker fusion that presents the subject with a series of
stimuli consisting of a flickering pattern of bars above or below a static rectangle. For
each stimulus presentation, the user has to tap the region that is flickering. The duration
of the app is less than 2 minutes.
This study will assess the validity of the test construct in measuring flicker fusion
thresholds, and serve as a foundation for further iterative designs of the app and future
validation and characterization studies.
