Recent advancements in brain-computer interface (BCI) technology have the potential to revolutionize various industries, including construction. A groundbreaking study led by SHI Tian-wei from the School of International Finance and Banking at the University of Science and Technology Liaoning has unveiled a semi-autonomous navigation system specifically designed for multi-rotor aircraft. This innovative approach focuses on two-dimensional indoor space target searching, which could have significant implications for construction site management and monitoring.
The BCI system integrates two key components: a semi-autonomous navigation subsystem and a decision subsystem. The navigation subsystem aids in steering the aircraft while avoiding obstacles, streamlining operations that are often fraught with challenges in complex environments like construction sites. “By reducing the burden on operators and enhancing control precision, our system can significantly improve efficiency in indoor target searching,” explains SHI. The study demonstrates that the control precision can be enhanced by approximately ±10 cm, a noteworthy advancement for applications requiring high accuracy.
One of the standout features of this research is its utilization of motor imagery (MI) electroencephalogram (EEG) for feature extraction and classification through cross-correlation and logistic regression methods. This not only allows for a more intuitive control mechanism but also opens the door for operators to engage with their environment in a more seamless manner. In practical terms, this means that construction managers could potentially oversee the navigation of drones or other aerial vehicles through thought alone, significantly reducing the need for complex manual controls.
The implications for the construction sector are profound. Imagine a scenario where site managers can deploy drones to survey hard-to-reach areas or monitor safety compliance without needing extensive training in drone operation. The potential for increased safety and efficiency in monitoring construction progress is particularly appealing. As SHI notes, “Our research paves the way for integrating BCI technology into various operational frameworks, making tasks not only easier but also safer.”
This research was validated through actual indoor target searching experiments, highlighting its feasibility and effectiveness. As construction firms increasingly turn to automation and smart technology, the integration of such advanced systems could redefine how projects are managed and executed.
Published in the journal ‘工程科学学报’ (Journal of Engineering Science), this study not only contributes to the academic discourse surrounding BCI technology but also sets the stage for practical applications in industries that demand precision and efficiency.

As the construction industry evolves, the marriage of neuroscience and technology promises to enhance operational capabilities, ultimately leading to safer and more efficient work environments.
