ABSTRACT
In this chapter, we present novel wearable systems for first-aid assistance based on video conferencing and augmented reality (AR) technology. The concept of a wearable computing system is under active research since components such as computers, sensors, and actuators are becoming smaller. Similarly, wearable virtual reality (VR) and wearable robotic systems have become a popular research topic [1-5]. Most mobile phones are now equipped with navigation functionality based on the global positioning system (GPS). However, the demand for guidance not only for transportation but also for other activities in daily life is expected to arise from the development of wearable technology [5-12]. Although people rarely need guidance from other people with respect to everyday activities, if, for example, one goes to the aid of an injured or ill person, receiving proper

instructions for first aid from an expert might be necessary. Potentially, there are a large number of tasks for which receiving guidance from the experts would be useful. In this context, we have proposed and developed wearable guidance systems for the purpose of providing general or specific guidance in various situations [9-12]. Hereafter, BNS stands for behavior navigation system and WBNS stands for wearable BNS, where the latter is expected to enable the wearer to perform first aid with the accuracy of an expert.
