Light Coded Language (LCL): Infrared-Thermography* based 3D Interactive Touch Sensing Display for Handling Medical Emergencies

Abstract

The human body radiates a long-wavelength IR of about 10 microns or 10 μm. Planck's law allows us to describe the amount of energy the body gives off as radiation of different frequencies in mathematical terms. The paper harnesses these IR properties for allowing surgeons to perform surgeries remotely. The paper proposes a system composed of a novel medical device [IR camera + Projector] with a pair of attached robotic arms that capture an image of a target organ of a patient and reproduce it at a remote location having another device [IR camera + Projector]. The paper discloses a method to reimage a 3D interactive display for the captured image that enables in-volume interaction with the stereoscopic 3D volume. The method provides an integrated touch sensing mechanism where IR cameras detect human hand, finger, and body interactions within the floating 3D display volume. As the surgeon interacts with the 3D display at the remote location, the actions are reproduced by the robotic arms provided on the medical device at the patient's location. Thus, by using 'Light Coded Language' in the form of 'infrared thermography,' depth sensing technology is employed for operating the patient remotely. The proposed system is explicitly outlined for conducting medical emergencies.
