Abstract

Although various types of electronic mobility aids for visually impaired persons have been developed as alternatives to the conventional white cane, users still have much doubt on the effectiveness and usability of these newly introduced aids. To identify ways to improve usability and effectiveness of electronic cane, a task performance study was conducted to examine the usability level of electronic canes using performance metrics (based on time-consumption and error rates). 20 visually impaired persons with and without prior experience using a white cane participated in a 2x2 factorial mixed-design experiment, in which they used two types of cane (white vs. electronic). Results showed that an electronic cane was more effective in avoiding obstacles than a white cane for both experienced and inexperienced users, and previous experience with a white cane was found to be beneficial for timely task completion.
