Figure 2. Mode.TOKYO application screenshots 2.2. Dongle interface The dongle for headphone-jack is a device developed and used in this implementation[8]. The dongle is linked with the smartphone application when the headphone-jack dongle is inserted into the phone. The dongle is recognized and identified when it transmits signals to the smartphone and the application confirms that the headphone-jack dongle is connected. A special characteristic of this device is the boosting and flow of a micro-current, supplied through the headphone-jack, by a booster circuit within the dongle. Thus, there is no need to charge or change batteries, and a user experience (UX) is available at any time through simple use of the device. Table 1 shows detailed specifications, while Figure 3 presents a view of the device. J.Suzuki etal. / System forMotivatingEthicalConsumptionBehavior 165
