Providing IoT Services in Smart Cities through Dynamic Augmented Reality Markers.

Area of Science:

• Computer Science
• Urban Planning
• Electrical Engineering

Background:

• Smart cities leverage the Internet of Things (IoT) for improved urban living.
• Mobile devices and augmented reality (AR) offer intuitive interfaces for complex systems.
• Current AR applications in smart cities often rely on static markers for device identification.

Purpose of the Study:

• To develop a novel method for enhancing smart city maintenance services.
• To improve the accessibility and real-time data retrieval from urban IoT devices.
• To integrate augmented reality (AR) with dynamic markers for seamless field service operations.

Main Methods:

• Proposed a system combining IoT and AR for smart city maintenance.
• Developed dynamic markers using LED communication for data transmission.
• Utilized smartphone cameras to decode dynamic markers and retrieve information.
• Replaced traditional static AR markers with a more efficient dynamic system.

Main Results:

• Dynamic LED markers successfully replaced static AR markers.
• Smartphone-decoded markers provided direct access to sensor data and object IDs.
• Eliminated the need for additional network interaction for data retrieval.
• Demonstrated improved accessibility and responsiveness in a smart city maintenance scenario.

Conclusions:

• Dynamic LED markers offer a novel and efficient approach for smart city IoT device interaction.
• This method enhances the usability of AR in urban maintenance by providing direct, network-independent data access.
• The integration of dynamic markers with mobile AR has significant potential for future smart city applications.
