NESS - navigation endoscopic sinus surgery with virtual endoscopy (VE) as well with virtual surgery (VS); While navigating through the narrow pathways in 3D/VE preoperatively, we noticed that the camera could stray into the tissue. Following this, getting back on the track seemed hard, sometimes even impossible without going back to the starting position

NESS in Klapan Medical Group Polyclinic – navigation endoscopic sinus surgery with virtual endoscopy (VE) and with telemedicine discussion during the surgery, with MDs from various medical institutions; we developed our special plug-in application for OsiriX platform, enabling users to use LM sensor as an interface for camera positioning in 3DVR and VE views

NESS – navigation endoscopic sinus surgery with virtual endoscopy and with Leapmotion surgery; our team defined different types of gestures for the 3DVR and for the VE which enable navigation through virtual 3D space, adjusting viewing angle and camera position, using only one hand

NESS – navigation endoscopic sinus surgery with virtual endoscopy and with Leapmotion surgery; we minimized surgeon distraction while interacting with the positioning system

NESS – navigation endoscopic sinus surgery with virtual endoscopy and with Leapmotion surgery ; we chose gestures that people can easily correlate with natural movements while interacting with real-world objects, making navigation as fast as possible, while maintaining precision and shortening learning time

NESS – navigation endoscopic sinus surgery with virtual endoscopy and with Leapmotion surgery; we integrate the speech recognition as a VC solution, in our a original way, which is not comparable with some projects which already exist on the market

NESS – navigation endoscopic sinus surgery with virtual endoscopy (VE) as well as virtual surgery (VS); there is a distinction between the interpretation of gestures in 3DVR and VE because of a different manner of movements while navigating throughout the virtual space

NESS – navigation endoscopic sinus surgery with virtual endoscopy (VE) as well as with virtual surgery (VS); the navigation in virtual space is achieved by assigning the three orthogonal axes

NESS – navigation endoscopic sinus surgery with virtual endoscopy (VE) as well as with virtual surgery (VS); the first evaluation of our system allowed us to observe users operating 3DVR and VE and adopting the principles of our proposed contactless interface

NESS – navigation endoscopic sinus surgery with virtual endoscopy (VE) as well as with virtual surgery (VS); we propose using the angles of palm position as values that represent speed of camera deflection. This approach would assure more precision while navigating VE space while also reducing working complexity

NESS – navigation endoscopic sinus surgery with virtual endoscopy (VE), virtual surgery (VS) and LM; the surgeon should have the option to look around and change camera orientation, while camera position cannot leave the predefined path

NESS – navigation endoscopic sinus surgery with virtual endoscopy (VE), virtual surgery (VS) and LM; using this approach, the surgeon can use swipe-like gestures for positioning which are more natural to humans than sign gestures

NESS – navigation endoscopic sinus surgery with virtual endoscopy (VE), virtual surgery (VS) and LM; in many cases, when entering sensor active area, the surgeon would keep an open hand (active state) which mostly resulted with sudden change in position and loosing orientation in space

NESS – navigation endoscopic sinus surgery with virtual endoscopy (VE), virtual surgery (VS); and ; is concentrated on the surgery being performed, and after he makes a decision to use VE, he doesn't think about the hand position which should be used when entering the active area (closed fist, indicating for inactive state)

Leap motion 3D - navigation surgery in rhinology (with "commands in the air") supported by virtual endoscopy and virtual surgery. Navigating through narrow pathways in VE, we noticed that the camera can stray into the tissue. Following that, getting back on track seemed hard, sometimes even impossible without going back to the starting position

Leap motion 3D - we propose a solution with predefined paths that would allow the user to navigate through the VE, which would reduce the interface control difficulty

Leap motion 3D - observing user interaction with the application we have seen that there was a need for voice commands that could reveal additional parameters and applications functionalities using a dashboard interface that can either overlay the current view or be shown on a separate computer screen if the environment allows it

Leap motion 3D - when choosing a ROI or a checkpoint to be activated, the user should be presented with a clear 3DVR or VE view with an unobtrusive list of ROIs or checkpoints with associate VCs

Leap motion 3D - in this way, we tried to understand the new, visualized “world of anatomic relations within the patient's head” by creating an impression of virtual perception of the given position of all elements in a particular anatomic region of the head, which exists in the real world and having an impression of the presence in VW12, navigating and/or tele-navigating through it and manipulating with virtual objects

Leap motion 3D - using 3DVR as a perception tool in OR requires preparation of slice images prior to joining the OR in order to identify and properly label critical concerns for the specific case

Leap motion 3D - definition of the system setup, as well as all the other important factors which we took in the account during the conclusion/decision of the computer and LM controller position in the OR are already described in our publicized literature

Leap motion 3D - LM - with the continuous usage, application and perfect control of 2D-MSCT and/or MRI medical images, as well as the navigation of 3D-models, VE or VS, simple no-touch “in the air” motions/commands of the surgeon’s hand in the OR, we have demonstrated the application of special plug-and-play devices for conducting of this sophisticated surgery to be unnecessary

Leap motion 3D - LM - the plug-and-play devices impose a burden for the surgeon and negatively contributes to their focus on the actual surgical procedures. Seeing how they are designed as additional HD which is placed on the side of the operation table17, it disrupts the focus of the surgeon how would have to be completely focused on their surgical procedure

Leap motion 3D - LM - therefore, during the planning and defining of the setups of all the important elements in the development of our form of this sort of surgery, in which the surgeon becomes “the master and coordinator of time and space” in the OR, we evaded the basic problems which self-impose with the development of this surgery strategy

To understand the idea of application of VR in tele-surgery of the 21st century it’s necessary to recognize that the perception of surrounding world created in our brain is based on information coming from the human senses and with the help of a knowledge that is stored in our brain
