Applying UML to Task Analysis of the User Interface for Rehabilitation Robotic Systems


The importance of usability has been largely increased in designing user interface when developing interactive systems. A user-centred approach is getting a popular standard to achieve better usability from the early stage of development. Usability issue is urgently required to rehabilitation robotics because the users of the rehabilitation robotics need more intuitive operation of the robotic systems. Task analysis can be one of the best methods to satisfy usability for user interface design. This paper reviews the roles of task analysis in designing user interface. Advantages and disadvantages of task analysis are briefly described, and UML (Unified Modeling Language) notations, which are presented as a solution in order to overcome the disadvantages of task analysis, are introduced. The use cases and activity diagrams are applied to the rehabilitation robotic system for limb injury recovery as a case study. The proposed system represented by UML will be helpful to communicate each other among people involved in developing the system including physiotherapists and other medical professionals. Also, the proposed system will be helpful to implement the usable and safe system.
