Application of the angular indication measurement and foraging interactive D-prime paradigms to tablet-based color...

Area of Science:

• Ophthalmology
• Vision Science
• Human-Computer Interaction

Background:

• Computer-based tests are common for evaluating color vision deficiencies (CVD).
• Existing methods require validation for new, portable platforms like tablets.

Purpose of the Study:

• To apply and evaluate the angular indication measurement (AIM) and foraging interactive D-prime (FInD) paradigms on a tablet for color vision assessment.
• To compare the performance of these tablet-based tests against established methods for CVD detection and discrimination.

Main Methods:

• Utilized tablet-based implementations of the AIM and FInD paradigms for color detection and discrimination tasks.
• Compared results from AIM and FInD tests with traditional assessments, including the anomaloscope, Cambridge Colour Test (CCT), and Mollon-Reffin test.

Main Results:

• AIM and FInD tablet tests demonstrated good agreement with the anomaloscope in identifying color deficiencies.
• AIM color discrimination showed higher concordance with anomaloscopy than AIM color detection.
• Combining detection and discrimination data from AIM or FInD yielded superior agreement compared to individual tests.

Conclusions:

• Tablet-based AIM and FInD tests offer a rapid, informative, and portable solution for CVD screening.
• These methods are suitable for both clinical settings and field research applications.
• The integration of detection and discrimination metrics enhances the diagnostic utility of these novel tests.
