A Wearable Ad Hoc Device for Situational Awareness and Trusted Collaboration

We develop a new wearable situational awareness and trusted collaboration system to solve several problems with existing wearable devices: a low degree of functional integration and use efficiency, the credibility of data and depending on some external facilities (such as the Internet and servers). We implement a variety of features on a wearable device, improve interaction efficiency by introducing Mixed Reality (MR) to the system. Besides, unlike existing infrastructure-dependent (e.g., for positioning or identification) devices, we use ad hoc network and embedded local modules to reach a offline implementation of information analysis and processing. Moreover, to guarantee the credibility of information in the ad hoc network, we use a lightweight blockchain among the devices. In this way, each device in the network can conduct local situational awareness and instant interaction with the user, and the information passed among users can also be considered credible.
