*3.5. The Mystery of TIKI TAKO*

The TIKI TAKO system for young T1D patients is an instantiation of the general PERGAMON framework. The characteristics of the TIKI TAKO system are presented in Figure 6 and Table 1. The Ground Layer of the TIKI TAKO system supports the storage of data and measurements about physical activity, glucose measurements, insulin intakes, and food. The Sensor Network of the TIKI TAKO system supports different channels and devices that are able to collect information about daily life activities via sensors. It supports the Google Fit service which collects information about physical activity (number of steps and activity intensity). Other sensors compatible with the Google Fit service could be used in the TIKI TAKO system to also collect data about physical activity. We used the Google Fit ©Pedometer (as a service on the smartphone itself, or on an Android Wear smartwatch) and the Xiaomi Mi Fit Band ©(in combination with the Mi Fit app) as sensors. Also the services and devices of iHealth are supported to collect physical activity or blood glucose measurements. Menarini ©blood glucose sensors are also supported to measure blood glucose. The Sensor Network also allows for manual input of information about diet, insulin and sleep.

Within the Gamification Platform five types of goals and tasks for young T1D patients have been implemented:


**Figure 6.** Main characteristics of the *Tako Game* (see Table 1 for explanation).

**Table 1.** Main characteristics and game elements of the *Tako Game* for diabetic children (see Figure 6).


The Serious Game component of the TIKI TAKO system consists of the main "Mystery of TikiTako" game and seven mini games. The main game is an adventure and puzzle game in which the player takes on the role of an investigator who tries to solve a mystery. The investigator, the main character in the main game, also has T1D. The player progresses in the game by successfully directing the main character to control his diabetes and solve puzzles through the mini games that have educational

goals, such as how to do insulin injections or how to balance blood glucose levels. Table 2 provides an overview of the seven different mini games and their learning objectives.
