Many people use on-vehicle information devices on a daily basis. These devices have many useful functions for route guidance, audio services, and gathering traffic information. In addition, smartphones are being used as on-vehicle information devices because of the ubiquity of low-priced applications that can be used.
Recently, smartphones have become widely used as vehicle information devices. As a result, several advantages haveappeared. First, a smartphone can log driving data such aslocation, vehicle status information, and so on. The logs donot depend on the car, but on the smartphone user. Second, a smartphone can gather driving-related information via theInternet. We believe that the advantages enable us...
Smartphones are replacing conventional on-vehicle information devices, and many driver-related smartphone applications are available in the market. On-vehicle information devices can recognize driver and environmental contexts in addition to the vehicle context. We discuss how to use these contexts to advance the operability of on-vehicle information devices and the user's experience. Then, we implement...
The current technology trend in automotive navigation systems is “Display Audio” devices. These are display devices that connect directly to and are controlled by the user's smartphone. However, such devices suffer problems of driver distractibility as well as problems related to differences in the life cycle of the Display Audio device and the smartphone. In this study, we discuss the state of current...
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)...
