Reliability of the Hand-Eye Coordination Test among Adults Using a Software: A Longitudinal Follow-up Study

 This study aims to determine the reliability of the hand-eye coordination Software. The integrated control of hand and eye movements, as well as the processing of visual information to support attainment and acquisition and the use of hand proprioception to guide the eyes, are known as hand-eye coordination. Thus, this study aims to determine the reliability of the tests, so the research was conducted thrice with an interval of 6-7 days (test-retest). 28 Young Adults (18- 35 years of age) have participated in the study. The analysis includes finger-pointing tasks performed only with the use of Hand-eye coordination software prepared by the Software engineer.In this Software, Visual targets in the form of a ball then appeared on the screen on the left, on the right, or in the center in random order., and participants were asked to point an index finger of the leading hand as rapidly and precisely as possible at all targets on the screen. After touching the target (indicated by its disappearance), the participant immediately placed his/her hand back in the designated starting position (touchpad).Each participant was required to repeat this finger-pointing task. The accuracy value after 1 minute was recorded and the average accuracy value was calculated and used in the analysis A smaller value indicates greater touch accuracy. In addition, the average reaction time (in milliseconds) was also measured. Based on the data analysis, the reliability score is 0.806 (Cronbach’s Alpha), which indicates a high level of internal Consistency.
