摘要

This study aims to improve the efficiency of hospital registration user interface by employing user's experience data. Users complete registration task under the guidance of a sequence of dialog boxes that lead the user through a series of well-defined steps, it is usually called Wizard Interface. Wizard Interface is good for first-time users due to its error prevention, but is troublesome for experienced users. This study intend to improve the usability of hospital registration user interface through Personalized Shortcut Options and Group Recommending Options. This study carried out observation study, hospital director interview, case study, and developed a prototype interface with Personal Shortcut Options and Group Recommending Options. Heuristic Evaluation was carried out for usability inspection in the process of prototype development. The evaluation of interface comprehension and learnability was completed by users experiment. Statistical results show that: (1) Applying personal user experience to develop Personal Shortcut Options can simplify the registration processes and improve efficiency. Through the experiment of learnability, users reached a plateaus of development after 2 to 3 times of practice. (2) Applying user group experience to develop Group Recommending Options that prompt options for majority users as priorities, significantly raise the efficiency of searching options. Users who choose option for minority users can also benefits from raising efficiency due to grouping effect of complex options. (3) Application of Responsive Disclosure can lead users to grasp the layout of interface; its effectiveness and feasibility are both verified.
