Abstract

As the number of overseas travelers with smartphones increases, there is a growing interest in smartphone applications, which can assist traveling. Typically, travelers need applications to obtain basic information, such as weather, map, currency, etc. However, existing smartphone applications are not suitable to do so because they require network connection that is expensive and unstable in overseas. For example, one of the most frequently used smartphone map application requires a network connection, and much battery to download images. Since travelers spend most of their time outside, there is no chance to charge the battery. In this paper, we propose a study on implementation of a smartphone application for overseas travelers, called Travel Manager, which aims to reduce usages of network connection and battery. Travel Manager first checks whether smartphone is connected to the network, and then synchronizes the travel information. It also automatically calculates traveling expenses by considering currency rate. That is, the proposed smartphone application can be used regardless of the network connection and minimizes the battery usage.
