The use of information technologies in the tasks of medical rehabilitation is an effective method, but it is often complicated by the problems of using standard control devices and input into the computer by people with motor impairments. The developed hardware and software complex allows one to obtain data on the orientation of the joint in space, "turning" them into the movement of the mouse pointer, allowing one to interact with computer software, instead of the mouse manipulator. By changing the sensitivity of the sensors, the process of rehabilitation of patients is corrected. The used component base of the complex being developed and the technologies used make it possible to form a significantly lower cost, the possibility of using it outside the clinic, working without the help of specialists, application in control actions with computer software not only for rehabilitation but also for people with disabilities. The paper defines the tasks and functions that are solved by the hardware and software complex. In the 3D editor, the body frame and the internal arrangement of components are modeled, hardware and software tools are selected to ensure the implementation of the project. The functional scheme of the "Limbtracker" device has been developed. During the execution of the project, the following was implemented: reading data from sensors and writing them to a text file, filtering data by the Kalman algorithm, calibration of the device.
