Development of Dynamic Real-Time Navigation System

Abstract

Abstract-This study aimed to develop a system that considers dynamic real-time situations to provide effective support for tourist activities. The conclusions of this study are summarized in the following three points: (1) The system was developed by integrating Web-GIS, social media, recommendation systems and AR terminals (smart glasses) into a single system, and operated in the center part of Yokohama City in Kanagawa Prefecture, Japan. It enabled the accumulation, sharing and recommendation of information and navigation to guide users to their goals both in normal conditions and in the event of disasters. (2) The web-based system was aimed at members of the general public over 18 years old and operated for seven weeks. The total number of users was 86, and 170 items of information were contributed. A system using smart glasses operated for two days, and the total number of users was 34. (3) Evaluation results clarified that it was possible to support user behavior both in normal conditions and in the event of disasters, and to efficiently and safety conduct navigation using smart glasses. Operation premised on disaster conditions showed that users who accessed the system via mobile information terminals increased, and actively used functions requiring location information.

A Sightseeing Spot Recommendation System for Urban Smart Tourism Based on Users’ Priority Conditions

“…Okuzono et al [6] took into consideration the preferences of several people using photos, and proposed a system that recommends sightseeing spots. Fujita et al [7], Sonobe et al [8] and Sasaki et al [9] proposed tourism support systems using augmented reality (AR). Among these, Fujita et al [7] used Web-GIS and social media in addition to AR in order to support sightseeing activities during normal occasions and evacuation in case of a disaster.…”

A Sightseeing Spot Recommendation System That Takes into Account the Change in Circumstances of Users

“…When each user registers at first, he/she is asked to rank the eight evaluation items (satisfaction level, access, non-crowdedness, accessibility for those with special needs, cost effectiveness, atmosphere, amenity and recommendation degree, which are the same evaluation items of the evaluation system mentioned in the previous section) on five levels, and the preference information is created. This is set as the user's feature vector, while the evaluation value (evaluation information) created by the evaluation system in the previous section is set as the feature vector of sightseeing spots, and the degree of similarity between these values is calculated using Equation (8).…”

“…The conceptual diagram concerning this process is shown in Figure 7. Regarding the evaluation information of sightseeing spots and user preferences (or group preferences) accumulated in the database, the degree of similarity will be calculated using Equation (8) shown in Section 3.4.3. Furthermore, the sightseeing spot information and evaluation values of the top 20 in similarity will be selected, sorted (filtered) according to the value of priority evaluation items, and the top 10 sightseeing spots will be displayed as recommendation results.…”

“…However, if the number of evaluators is extremely low, the evaluation values obtained from the aforementioned preceding study are used, and the evaluators are each counted as one person. Referring to Ikeda et al, 2014 [29], Fujita et al, 2016 [8], and Zhou et al, 2016 [16], the system categorized all sightseeing spots into six categories including "food and drink", "shopping", "amusement parks and parks", "famous and historical sights", "art and historic museums" and "others (events, etc.)". …”
