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

Abstract

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

Human-Machine Interface Evaluation of CNC Machine Control Panel through Multidimensional Experimental Data Synchronous Testing Analysis Method

“…Lin and Zhang [16] presented a study on a more objective evaluation technique based on the combination of operators' eye movement and hand movement behaviors. Andreoni et al [4] evaluated portable ultrasound systems user interfaces using motion analysis and eye tracking technologies. They described the ergonomics and usability preliminary tests regarding the human upper limb kinematics and cognitive evaluation of two diagnostic portable ultrasound scanners.…”

Usability Engineering of Games: A Comparative Analysis of Measuring Excitement Using Sensors, Direct Observations and Self-Reported Data

“…On the other hand, the authors state that Tobii Studio has the advantage of using the eye-tracking feature which help in capturing the eye movements of the participant [1]. Another user experience study has been conducted to compare the interface design of two portable ultrasound scanners [7]. In this study, cameras and eye-tracking device were used to observe the sonographers' eyes and upper-body kinematic while they were using the scanners.…”

Eye Tracking Based Experimental Study on Basic Digital Control Panel Usability

“…The authors developed a methodology for evaluating such interfaces that takes into account, among other things, the oculographic data. In a study of [1] on control panels researchers examined usability of portable ultrasound systems interfaces by means of the motion and eye balls movement analysis.…”
