Development of a mobile application for testing fine motor skills disorders

The purpose of the article is development of a mobile application to test graphic skills and disorders of fine motor skills determination. 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 was developed to test basic graphic skills and level of fine motor skills development. The algorithm for the determination of 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 Engineering of 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.
