Bottom Line: These IDs allow information about the objects to be retrieved from a remote server.In this work, we present a novel solution that replaces static AR markers with dynamic markers based on LED communication, which can be decoded through cameras embedded in smartphones.These dynamic markers can directly deliver sensor information to the rendering device, on top of the object ID, without further network interaction.

ABSTRACT
Smart cities are expected to improve the quality of life of citizens by relying on new paradigms, such as the Internet of Things (IoT) and its capacity to manage and interconnect thousands of sensors and actuators scattered across the city. At the same time, mobile devices widely assist professional and personal everyday activities. A very good example of the potential of these devices for smart cities is their powerful support for intuitive service interfaces (such as those based on augmented reality (AR)) for non-expert users. In our work, we consider a scenario that combines IoT and AR within a smart city maintenance service to improve the accessibility of sensor and actuator devices in the field, where responsiveness is crucial. In it, depending on the location and needs of each service, data and commands will be transported by an urban communications network or consulted on the spot. Direct AR interaction with urban objects has already been described; it usually relies on 2D visual codes to deliver object identifiers (IDs) to the rendering device to identify object resources. These IDs allow information about the objects to be retrieved from a remote server. In this work, we present a novel solution that replaces static AR markers with dynamic markers based on LED communication, which can be decoded through cameras embedded in smartphones. These dynamic markers can directly deliver sensor information to the rendering device, on top of the object ID, without further network interaction.

f10-sensors-15-16083: 6LowPAN protocol stack.

Mentions: The CoAP protocol [37] was chosen for the application layer, using UDP as the transport protocol (Figure 10). This protocol allows the implementation of REST interfaces over constrained networks formed by nodes with limited resources. Thus, each node can be accessed and its resources modified using CRUD (create, read, update and delete) methods. Moreover, CoAP has been designed to support HTTP bridging, so external devices (outside the network) not implementing the CoAP protocol may access node resources directly if an HTTP/CoAP bridge is included in the network.
