Motion analysis and eye tracking technologies applied to portable ultrasound systems user interfaces evaluation

The present work describes the ergonomics and usability preliminary tests regarding the human upper limb kinematics and cognitive evaluation of two diagnostic portable ultrasound scanners. The tests were performed by two sonographers (an expert one and a novice one) on one subject in abdominal and vascular clinical applications. The two portable systems had different user interfaces: one system had a classic Software keys interactive Menu, placed in the lower part of the screen, with toggles and buttons for the activation and adjustment of the functions, then physical qwerty keyboard and control panel. The other system had a touch screen integrated in the control panel with an interactive user interface and reduced number of physical buttons. Comparisons between the two systems considering the two sonographer's use are provided. Motion control and eye tracking scan path results will be presented and discussed for both users on both systems.
