Abstract

Background
Current methods to measure eye–hand coordination (EHC) have been widely applied in research and practical fields. However, some aspects of the methods, such as subjectivity, high price, portability, and high appraisal contribute to difficulties in EHC testing.

New methods
The test was developed on an Apple iPad® and involves tracing up to 13 shapes with a stylus pen. The time taken to complete each trace and the spatial accuracy of the tracing is automatically recorded. The difficulty level for each shape was evaluated theoretically based on the complexity and length of outline. Ten adults aged 31.5 ± 7.8 years and five children aged 9.4 ± 1.1 years with normal vision participated.

Results
In adults, the time taken to trace and number of errors significantly decreased from the first to the second attempt (p < 0.05) but not thereafter, suggesting a learning effect with repeatability after a practice attempt. Time taken and number of errors in children were both higher in monocular than binocular viewing conditions (p = 0.02 and p < 0.01, respectively) while adults’ performance was similar in both viewing conditions.

Comparison with existing methods
Existing EHC tests are subjective in clinics and require higher skills and cost in research, and measure gross EHC. This novel test has been developed to address some of the limitations.

Conclusions
The test is engaging for children and adults and is an objective method with potential for the assessment of fine EHC, suited to clinic-based and research use in ophthalmic or brain trauma settings, and in developmental disorders.
