Abstract
Some criticisms, such as input difficulty, security, and so on, have been pointed out as flaws in systems of electronic medical records. We have been long engaged in development of the pen-based interface to improve these flaws and promote the use of electronic medical records. However, the evaluation of effectiveness of this interface has not been performed thoroughly enough yet. We did conduct a survey using questionnaires, which asked 244 people about this interface in seminar. Responses were obtained from 82 people. Of these people, 67(81.7%) agreed that the assistant functions in this interface were useful. Particularly, the pen ID function scored higher than all other assistant functions. As well, 57(69.5%) people answered that our pen-based interface would promote the use of electronic medical records. Wilcoxon's signed ranks test showed that the pen-based interface is significantly easier to use than a keyboard interface, especially for outpatient consultation (p<0.01). It turned out that most of the respondents expected that the pen-based interface could have potential to improve shortcomings in the systems of electronic medical records. These results suggest that the pen-based interface will be effective in popularizing electronic medical records.
