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.

f1-sensors-15-16083: Dynamic LED marker.

Mentions: In this work, we propose a new type of optical AR anchor that allows precise definition of the area of interest for media overlays while providing a direct low-bandwidth communications channel for dynamic information. To achieve this, instead of static markers based on images or QR codes, we employ an LED matrix that can be easily read by most personal device cameras nowadays. A basic diagram of this dynamic marker is shown in Figure 1.
