In the medical field, a serious problem exists with regard to communication between hospital staff and foreign patients. For example, medical translators cannot provide support in cases in which round-the-clock support is required during hospitalization. We propose the use of a multilingual communication support system called the Petit Translator between people speaking different languages in the hospital setting. From the results of experiments performed in such a setting, we found the following: (1) by clicking the conversation scene, the interface can retrieve the parallel text more efficiently than the paper media, and (2) when a questioner appropriately limits the type of reply for a respondent, prompt conversation can occur.
Five kinds of product search HTML pages -a four-level hierarchy (3 x 3 x 3 x 3), a three-level hierarchy (9 x 3 x 3), a two-level hierarchy (27 x 3), a one-level hierarchy (81 x 1), and a frame structure (9 x 3 x 3)were prepared. Two kinds of task, a simple task and a complex task, were prepared. For the most complex task, a total of 22 clicks were required to complete the task. Then the subjects were asked to search for products over the Internet. They were also asked to evaluate ease of use of the web pages. A total of 89 subjects accessed the experimental pages. The access log was later statistically analyzed. The results were very productive. In most advanced research up to now it has been shown that reducing the number of hierarchies and increasing the amount of information in one screen can reduce the task performance time. Our test results have also shown that this is what happens when a complex task is performed. However, a different conclusion is drawn when a simple task is performed. When a simple task is performed, there were no significant differences in the search time required, whether there were 81 products included in one screen (81 x 1), or in a four-level hierarchy (3 x 3 x 3 x 3). In this case, more people evaluated the four-level hierarchy as being easier to use than a one-level hierarchy. In this study it was found that task performance times and ease of use depend on task complexity and they were not always directly related.
In a ubiquitous computing environment, the operation information on a product is collectable to a homeserver.
Operation information in this paper means that the button on an operation panel are pushed and the door of a refrigerator are opened.
This data is very extensive and is a motion level.
Authors consider analysing this information by datamining method.
That is, it is extracting the information about usability out of operation information by datamining.
The authors propose this called In-Situ Ergonomics: gathering data from products in the actual situation, analysing data with datamining method and extract information for ergonomics research.
In order to realize In-Situ Ergonomics, the following serves as a subject.
- The collection method of the user operation information from each product
- The accumulation method of a lot of data
- The semantic analysis of operation information
- datamining method
- The cooperation method with the existing usability analysis method
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
