The purpose of this research is to develop a mobile application to identify fine motor disorders and help in their development.Many techniques are used to test fine motor skills, including drawing, cutting, folding, creating compositions from various materials, and more. However, using digital devices to test fine motor skills will be automatic, useful, and helpful. Digital devices such as sensor and graphic tablets, sensors, digitizers,and smartphones can provide accurate measurements of reaction times and movement speed, and allow real-time data to be recorded and analyzed.A cross-platform tool wasdeveloped to test basic graphic skills and level of fine motor skills development. The algorithm for the determinationof the graphic abilities of users is based on the Frechette discrete distance formula, which allows measuring the deviation of an experimental figure from the etalon figure. Experimental results were conducted at the Laboratory of 3D Biomedical Technologies of the Department of Biomedical Engineeringof Kharkiv National University of Radio Electronics.The application is designed to analyze graphic skills through a series of exercises that test various skills, such as drawing, shading, and coloring shapes.
