“…There are also some expensive options like the head-mounted displays (HMD) that can detect hand gestures. Some examples are Google Glass [34] and Microsoft HoloLens [35], the Oculus also can be included with a mounted Leap Motion, but we are interested in a more natural way for the user, without using wearable or touching devices. These approaches are limited in accuracy and precision of current visionbased devices for tracking hand movements, as well as their inherent issue of visual occlusions.…”

Hand gesture recognition is an important topic in natural user interfaces (NUI). Hand features extraction is the first step for hand gesture recognition. This work proposes a novel real time method for hand features recognition. In our framework we use three cameras and the hand region is extracted with the background subtraction method. Features like arm angle and fingers positions are calculated using Y variations in the vertical contour image. Wrist detection is obtained by calculating the bigger distance from a base line and the hand contour, giving the main features for the hand gesture recognition. Experiments on our own data-set of about 1800 images show that our method performs well and is highly efficient.

“…As most other devices are one-body structure, and head-mounting may cause headache or neck pain in the surgeon. An eyeglass-type recording device may reduce these disadvantages, but the image quality of current models is low and have shorter battery time 6,9,10) . Surgical lighting is important for the recording image quality due to the performance of the action camera.…”

Video recording is essential to training and education in the medical field. The recorded videos are used to education. There is less chance of experience in emergent or urgent traumatic brain injury (TBI) surgeries for residents. We used wearable action camcorders for surgical image recording in TBI, then evaluated its safety and feasibility for education. Methods: A wearable action camera was used to record surgical procedures. High-definition (1920×1080 p resolution, 60 frames per sec) quality was set and the camera was attached to the surgeon's head and recorded the view of the surgical field as seen by the surgeon. Burr hole trephination, craniotomy for hematoma removal, and decompressive craniectomy surgeries were recorded. The recorded video clips were stored securely and reviewed. To evaluate the usefulness of the images, we conducted reviews and surveys of the residents. Results: From January 2015 to December 2016, 81 cases of TBI surgery were recorded. Most video clips had a favorable view and image quality. Image distortion by overexposure occurred in 5 cases. Shut down due to misuse of device occurred in 2 cases and the recordings were out of focus in 5 cases. Results of the survey showed that TBI surgical video clips were helpful for understanding the sequence of surgery and sharing the field of view of the main operator. Conclusion: Wearable action camera can be used to record surgical video clips, including TBI surgery, and its videos may be helpful for the training and education of neurosurgery residents.

“…This technology has the potential to be used by medical and surgical practitioners in both practise 2, 3 and education. 4 The potential for smart glasses in interventional radiology has previously been considered, [5][6][7] concluding that they can offer improvements in patient safety, operator comfort and procedure efficiency. During these procedures the clinician may be looking at their hands, equipment or a real time image on a computer monitor produced either by a Computer Tomography (CT) scanner, fluoroscopy or an ultrasound machine.…”

Radiation protection value to the operator from augmented reality smart glasses in interventional fluoroscopy procedures using phantoms

Introduction: Smart glasses can be adapted to display radiographic images to allow clinician's gaze not to be directionally fixed or predetermined by computer monitor location. This study presents an analysis of eye lens dose during interventional fluoroscopy guided procedures, comparing fixed monitor positions against the use of smart glasses.Methods: Using a head phantom (simulating the clinician), thermoluminescent dosimeters and lead shielded glasses, the dose to the eye was measured for different head 'rotations and tilts' for: gaze directed towards the main scattering source (patient / primary beam) to represent potential gaze direction if smart glasses are used; gaze directed to a range of potential computer monitor positions. An anthropomorphic pelvis phantom was utilised to simulate the patient. Accumulated dose rates (µGy.sˉ¹) from five 10-second exposures at 75 kV 25.2 mAs were recorded.Results: An average DAP reading of 758.84 cGy.cm 2 was measured during each 10 second exposure. Whilst wearing lead shielded glasses a 6.10fold reduction in dose rate to the lens is possible (p<0.05). Influence of the direction of gaze by the clinician demonstrated a wide range of dose rate reduction from 3.13% (p=0.16) to 143.69% (p<0.05) when the clinician's gaze was towards the main scattering source. Increased dose rate to the clinician's eyes was received despite wearing lead shielded glasses, as the angle of gaze moved 45º and 90º from 0º.Conclusion: If the clinician's gaze is directed towards the main scattering source a potential exists for reducing eye lens dose compared with fixed location computer monitors. Introduction of lead lined smart glasses into interventional radiology may lead to improvements in patient care, reducing the need for the clinician to look away from the patient to observe a radiographic image.
