Efficiency or Quality of Experience: A Laboratory Study of Three Eyes-Free Touchscreen Menu Browsing User Interfaces for Mobile Phones

摘要

A growing number of individuals who are blind or visually impaired is using smartphones in their dailyactivities. The touchscreen is a standard component of smartphones. While benefitting people with low vision byenhancing control of the text style and color and the size of images and text, the touchscreen has the downside for visuallyimpaired users in that physical buttons for input of command selection and text entry are replaced with the touchscreen'ssoft buttons. To overcome this limitation, we are investigating eyes-free approaches to using the smartphone'stouchscreen for information browsing. In this article, we present a laboratory study of three eyes-free touchscreen userinterfaces for browsing menu hierarchies. Our findings indicate that quality of experience and familiarity may be asimportant as the time efficiency of completing tasks.
