63 Étienne Léger parts of the operating field through a movable AR window for instance. All of these customizations can be done directly on the device using touchscreen interactions and enable real-time control over the guidance for the surgeon. The results of his work show the feasibility of using mobile devices to improve neurosurgical processes. Augmented reality enables surgeons to focus on the surgical field while getting intuitive guidance information. Mobile devices also allow for easy interaction with the neuronavigation system thus enabling surgeons to directly interact with systems in the operating room to improve accuracy and streamline procedures. To encourage further research and accelerate the pace of innovation, Étienne released the developed application under an open source license, making it accessible to others to reuse and keep improving upon.
