**6.1. Evaluation based on Web questionnaire survey**

#### *6.1.1. Overview of the Web questionnaire survey*

Along with the purpose of the present study, a Web questionnaire survey was implemented in order to conduct an evaluation on the use of the system, an evaluation on system function, and an evaluation of the entire system. The Web questionnaire survey was conducted for 1 week after the start of the operation. **Table 1** also shows an overview of the Web questionnaire survey. As shown in **Table 1**, 36 out of 73 users submitted their Web questionnaire survey, and the valid response rate was 49.3%.

## *6.1.2. Evaluation on the use of the system*

Regarding the viewing frequency of the Website, 75% viewed the Website every day, and 19% viewed the Website several times a week. Regarding the access methods to the system, 44% were PCs, and 56% were mobile information terminals. Therefore, it was made evident that the system developed using the Web-GIS as a base system is useful. Additionally, because the access method from the PC and the mobile information terminal was hardly different, it was effective to make the system available from both terminals.-

#### *6.1.3. Evaluation of system function*

The evaluation results for the usefulness of the main functions to support walking are shown in **Figure 8**. Specifically, **Figure 8** shows the results that asked the users whether these items are useful.

**Figure 8.** Evaluation of the usefulness of the main functions to support walking.

Regarding the display function of walking course, 94% answered "I think so" or "I somewhat think so," 3% answered "I don't think so," and 3% answered "I don't think so at all". Because it is important to select a suitable walking course, the usefulness of this function was highly evaluated. Regarding the display function of the elevation difference of walking course, 69% answered- "I think so" or "I somewhat think so," 28% answered "I do not think so," and 3% answered "I do not think so at all". The reason for this result is that 56% of the users of the system were in their 20s, and they did not pay attention to the elevation difference of walking courses.-

Regarding the viewing function of the sightseeing spot information related to walking courses, 89% answered "I think so" or "I somewhat think so," and 11% answered "I don't think so." Because most respondents tended to select the walking courses with a lot of sightseeing spots. Regarding the viewing function of information related walking courses submitted by Twitter, 53% answered "I think so" or "I somewhat think so," 36% answered "I don't think so," and 11% answered "I don't think so at all." Consequently, 47% of the users did not highly evaluate the usefulness of this function. Because these users did not have their Twitter accounts, and it was impossible for them to directly submit information to the system.

Regarding the registration function of walking information, 61% answered "I think so" or "I somewhat think so," 6% answered "I don't think so," and 33% answered "I don't think so at all." However, the function may be used more often by the continuous operation of the system, and this may advance the usefulness of the system when walking.

#### *6.1.4. Evaluation of the entire system*

The evaluation results for the usefulness of the entire system are shown in **Figure 9**. As with **Figures 8** and **9** shows the results that asked the users whether these items are useful.

Regarding the entire system when walking, 81% answered "I think so" or "I somewhat think so," and it was evident that the system was highly evaluated. Though it is necessary

to improve some functions according to the users' evaluation results, it can be said that the system was useful to select a favorite walking course in responding to each user's preferences, aptitudes, and situations.

Regarding the interface of the entire system, though 53% answered "I think so" or "I somewhat think so," 47% answered "I don't think so" or "I don't think so at all." The reason for this result is that the interface optimized for mobile information terminals was not developed. Regarding the selection of suitable walking courses, 89% answered "I think so" or "I somewhat think so." Therefore, the system is useful for almost users to select their suitable walking course.
