Abstract [en]

In this work we assess four prototypes of gaze-supported input devices that aim o be more ergonomic alternatives than the mouse and touchpads for day to day omputer usage. These prototypes (nunchuck, ring, smartphone and trackball)have hree properties. First, they enable a distant interaction from the computer, letting he user have a 135-degree body-thigh sitting posture. Second, they allow one-handed nteractions, a convenient setting for people that can only use one hand due to rgonomic complications in the other one. And last, they are based on familiar nput technologies and conventions, so users can easily learn how to use them. An xperiment on pointing and drag & drop tasks was conducted to evaluate quantitative roperties of the devices and get qualitative user feedback. The smartphone ranked first n almost all the user feedback entries. The measures of speed and accuracy presented everal outliers. According to the measured results, the smartphone was the fastest ointing device and the most accurate for every task; the trackball was the fastest evice for drag & drop tasks. The nunchuck ranked last in all the measures. Based on his study, future work should be conducted on improving the design of the companion evices based on multitouch and trackball technologies.
