# A Study on the Development of Tourist Support System Using ICT and Psychological Effects
## 6 Experiment of Application Using Prospect Theory  
### Outline of the Experiment  
The experiment aimed to conform to the effectiveness to provide appropriate sightseeing information to meet the traveler's situation. We performed two experiments to evaluate the sightseeing application. The outline is described in Figure 15.

Figure 15: Outline of the experiment.  
The first experiment was carried out on 9 and 10 December 2019. Fifteen students from Utsunomiya University participated in this experiment. Nine examinees used smartwatches (Apple Watch), and six examinees did not use them. The second experiment was carried out on 18 March 2020. Four students from Utsunomiya University joined this experiment, and all of them wore smartwatches (Apple Watch). Because of COVID-19, the large-scale experiment was not allowed by the university and government, so we experimented to confirm the parameters' effect to calculate the information value using the Prospect Theory.  
We evaluated the application by the following points.  
* Awareness of BLE beacon
* Change of value of the reference point
* Distribution of information value
* Evaluation of the delivered information
* Change of image of Nikko  
Figure 16 shows the route of experiments from Nikko Station to Toshogu Shrine. There were 13 BLE beacons on the route, and the distance between two beacons was about 100 m.
