The Design and Evaluation of an Eyes-Free Touchscreen Interface

The eyes-free touchscreen interface is a category of interfaces for controlling devices with minimal visual attention. We apply design framework the generation imaginary layouts and propose series input menu selection, arrow control, data entry. These are oriented around U-shaped diagonal optimized one-handed thumb interaction. experiment tests participants’ cognitive performance toward specified layouts. In addition to examining accuracy discrete serial tasks, interviews conducted more qualitative feedback on user perception. results demonstrate that new formats viable interaction in line previous practices interface. Spatial straight alignment (1D) placed closely object reference frames within functional area unified frame, enhance accuracy.
