This research aims to design a sensor-based hand-eye coordination measuring tool and test its validity and reliability. A total of 9 experts were involved in assessing its feasibility, each of them 3 sports measurement experts, 3 motor experts, and 3 technology experts. Meanwhile, 50 students at one of the Faculty of Sports Sciences, Indonesia participated in field trials. Participants were students taking physical condition courses (aged 18-20 years), consisting of male (n1=30) and female (n2=20). A validation questionnaire was prepared and discussed with experts as a guide in providing an assessment of the relevance of the instrument (suitability, accuracy, ease, and practicality of the tool), and test-retest reliability for field trials carried out twice with the difference between the first and second tests being one week. Data were analyzed using Aiken's V Index, Intraclass Correlation Coefficient (ICC), and Pearson correlation. The research results showed that the assessment of all aspects of the measuring instrument was in the high category, and the ICC value also showed no differences between assessments (P>0.05). Then, the test-retest reliability testing results obtained a significant regression analysis with a high correlation coefficient (r=0.801; P<0.05). In conclusion, this measuring tool can collect data to improve performance in sports involving hand-eye coordination (such as volleyball, badminton, tennis, basketball, hockey, martial arts and other sports that predominantly use the hands), both for coaches, athletes and sports practitioners. Keywords: validity, reliability, coordination, sensors
