Description
We present implementation of navigational devices in application for viewing 3-d medical images obtained with CT scan. Those devices are Leap Motion - device which detects the movement of user hand in space and allows user to interact with computer with touch-less interface. And Connexion SpaceNavigator 3-d Mouse which is frequently used in 3-d modeling applications. In addition to the implementation of support for the device in the application we carried out a user study in which we assessed the usability and ease of use of devices in the application. Main goal was to obtain feedback from people who work in medical environment and are met with image analysis challenges on daily basis. The results consisted from data we collected from the users' experience while they solved various manipulation tasks and the answers received from questionnaires SUS (System Usability Scale) which constitute one of the tools with which we can assess interfaces. Analysis of the results confirmed that the 3-d mouse is more useful in such an environment and also highlighted some shortcomings of the hands free navigation device Leap Motion.
