As the convergence era with enhanced multimedia functions has been developed, various devices have been developed in the form of touch screens for efficient operation of the users, and these changes have also affected the medical devices, and the touch screen panels have been used. The purpose of this paper is to analyze the interface design of the touch screen panel, which has been used from the ultrasonic diagnostic equipment, and to propose a design improvement. First, we set up a Task Process through a FGI interview with a group of experts using ultrasonic diagnostic devices and then perform usability evaluation by task process. The usability evaluation of each screen element was made based on Jakob Nielsen 's heuristic evaluation, Norman's evaluation and HIMSS usability evaluation. As a result, firstly, it was found that GE and Philips products showed high evaluation results in usability test evaluation by task process, so they developed products considering usability for each task process considering user 's workflow. Secondly, in the evaluation of Graphic Uer Interface elements, Medison and Alpinion products were highly evaluated in terms of the emotional element which shows the overall aesthetics. |
