Recently, medical records can be accessible from Electric Health Record(EHR) in some regions such as e-maiko.net. EHR provides patient's records in patient's hands even though the authorized access requires the information literacy. Therefore, this research aims to provide an environment of short-step EHR access. The authors propose the EHR design to separate the data handling layer and the visualization layer. By the construction of the web access data interface and the visualization of the device optimized viewer, the system can select the visual interface depends on the situation and the viewer devices. Especially, the environment was implemented on the e-maiko.net. Also, the iPad application was provided for the experiment of the optimized visualization. The experiment was carried out with 9 subjects who are the expert of computers, are the novice of tablet terminals. The experiment compaired the perfomance of the access time to find a document between the conventional web interface and the iPad viewer interface. The result of experiment suggested that the iPad viewer makes the EHR access much more easier than the conventional web interface. Also, the result of interviews, the half of the subjects pointed out the security concerns to use mobile devices to access EHR. On the other hand, the rest of the subjects insisted the benefit of short-step access rather than the security issue. For the conclusion, the proposed system will be acceptable as an EHR browsing environment if the system is enough explained about the security issue.
