Intelligent User Interface of Smartphones for On-vehicle Information Devices

The current technological trend in automotive navigation systems is toward “Display Audio” systems connected to a smartphone. However, there are some issues stemming from the differing life cycles of on-vehicle information devices and smartphones. Therefore, we expect that Display Audio will result in simple I/O devices connected via smartphones and a car-based network (e.g., Controller Area Network). However, there are numerous situations when it is necessary for a driver to easily and safely operate on-vehicle information devices. In this paper, we first discuss various types of on-vehicle information devices, and their intended use in driving situations. Second, we discuss the relation of those situations to various on-vehicle information applications. Third, we propose a simple user interface (UI) for connecting on-vehicle information devices. To conclude, we discuss the UI for on-vehicle information devices, based on context-aware technologies
