# A Study on the Development of Tourist Support System Using ICT and Psychological Effects
## 3 CogInfoCom  
In this section, we discuss the relationship between the cognitive model of our application and the CogInfoCom model in [38; 39]. The CogInfoCom model includes \"intra-cognitive infocommunications\" and \"inter-cognitive infocommunications\" (p. 77 in [38]). \"Inter-cognitive infocommunications\" describe the relationship between a human and sensors or other autonomous cognitive systems. However, in the case of a cognitive model of sightseeing, we have to consider our memory, in other words, the inside of our brain. Figure 2 presents an idea to extend \"inter-cognitive infocommunications\" to describe the cognitive model of sightseeing and our application that works with BLE beacons. In [40], we extended the original model outlined in [38]. Figure 2 shows the original model of \"inter-cognitive infocommunications\", and Figure 2 is the extension of it to describe the cognitive model for sightseeing. The difference between Figure 2 and Figure 2 is the position of \"cognitive informatics\". In our sightseeing support system, BLE beacons are used only for providing location and not an active sensor. A smartphone receives a signal from the beacon, and a user reacts inspired by the information provided by the beacon. The activity causes the good or bad memory of the location and of the activity itself. This process is an example of cognitive informatics between the human activity and the memory in a brain. What is established between the location (beacon) and the cognitive model in a brain is instead an example of \"inter-cognitive infocommunications\". In this paper, we extend the model again as shown in Figure 2. This figure introduces intra-cognitive informatics to explain the information delivery path between a smartphone and a tourist. Usually, a tourist uses a smartphone for navigation. However, using a smartphone during sightseeing, especially while walking, is dangerous. Moreover, a tourist may miss noticing the beautiful scenery and historic buildings while he/she looks at the small screen. Therefore, we think it is essential for a tourist to use a wearable device instead of a mobile phone. Figure 2 explains that information from a smartphone is selected and prioritized based on his/her interest and behavior during sightseeing. A wearable device changes media of communication using vibration or audio. We defined this process as \"intra-cognitive information\". We think selection and prioritization are essential for a tourist in this model. One of the problems in retrieving the information about a traveling area is the presence of excessive information on the Internet. If a tourist can use a smartphone, he/she can select the most appropriate information

from the content listed on the screen. However, if a tourist does not use a smartphone, he/she can receive a small amount of information. Therefore, the quality and value of information should be high and minimized after the filtering. In this paper, we would like to explain how we designed the \"intra-cognitive information\" function in our sightseeing support application and discuss the results of our experiments.
