The Interface Development of Chinese DAISY Player Operation Procedure

The Digital Accessible Information System, or DAISY, is an international standard by which electronic books are produced for print disabled individuals. There are tens of millions of visually impaired people using the Chinese language. The DAISY reader/player has tremendous potential in giving them the same access to books that the general public has. This research examines the development of a Chinese-language user interface for a DAISY player prototype that can be used by Chinese users. The user interface is designed based on universal design rules and American National Standards Institute (ANSI)/National Information Standards Organization (NISO) Z39.86 2005. The design results are evaluated by using the Goals, Operators, Methods, and Selection Rules (GOMS) for experiments. Three commercial DAISY players and the Chinese language user interface prototype designs are compared by a group of visually impaired subjects in an experiment consisting of four tasks. The operating times, operating errors, and the mental workloads on the four interfaces are measured and compared for the experiment. The results of the experiment indicate that the prototype design has great potential and, as a result, will be included in the next version of the DAISY player.
