Periodic Reporting for period 1 - NGEAR 3D (Next Generation Enhanced Augmented Reality 3D Glasses for medical education, pre-procedural planning, intra-procedural visualization, and patient rehabilitation)
Reporting period: 2020-07-01 to 2021-06-30
NGEAR3D is a state-of-the-art multi-focal accommodating AR headset that eliminates all adverse effects of existing headsets and outputs holographic look 3D images. It completely solves current pains of near-work application with VA conflict for true application of AR in the healthcare sector. The NGEAR3D is compact, lightweight and wearable around the head and fits comfortably to both eyes (binocular vision). It is ideal for healthcare professionals who require 3D glasses for near eye imaging and can be safely used for long hours without discomfort to eyes and mind.
The core technology of NGEAR3D is the proprietary liquid-crystal optical switcher elements, that can be electronically switched between transparent and optically diffusive state in <500 microseconds. Several optical diffuser elements are stacked to form a discrete volume - volumetric 3D display. This static volumetric technology provides real 3D volumetric holographic imagery, thus matching it perfectly to the real world.
When applied for healthcare applications, it improves efficiency of surgeon & reduces time required, risks and medical complications of operations leading to more patients receiving treatment sooner. NGEAR3D will be a disrupting link for the image guided surgery to really take-off and benefit patients and medical patient & medical personnel.
It followed by Headset product development and engineering. Detailed engineering specification and requirements document and specification have been developed. Important specifications were included, including definition of number and positions of optical focal planes, head tracking technology and eye tracking technology. Optimal fast data transfer and MFOE driving platform development has started including work on optimized data transfer. The image formatter PCB has been redesigned and prototypes built that improves image quality, reproduction and data interface (using standard Display Port 1.4 specification) to the image source (GPU computer) and to interface the DLP unit (also image display unit based on micro-OLED displays) with PCB connection. This has been achieved by improving image data transfer (up to 24Gbps) and introduction of high-speed INTEL FPGA based data formatter processor chip.
Development and optimisation of AR projection optics of NGEAR3D has been performed to ensure required optical performance, functionality, dimensions, weight and manufacturability. The NGEAR3D has been redesigned to be lighter, with an optical combiner that will limit parasitic reflections. Signal data path development started, including small size data source device development. Task involves the development of a compact graphical computer for transfer of image data for the NGEAR3D headset. Optionally a single PCB are in design process to carry out required functionality. Several interim prototypes have been tested and connectivity data transmission path has been developed to verify key parts.
Further development of rendering engine was continued including developmentof the computing pack platform including rendering pipeline and control of the NGEAR3D headset device, with minimal motion-to-photon latency. The firmware stack data path development started with high-speed digital signal transfer implementation over appropriate carrier (USB-C, DisplayPort, or WiFi6E).
Inittial work started un industrial design of the product and packaging for user experience and ergonomics. Work include modeling and manufacture prototypes.
Prototype pilot tests and validation - execution of task has started earlier than scheduled by project plan – the first early prototypes has been already validated by two global leading robotic surgery technology teams, Karolinska Institute neurosurgery and AR technology teams. Project schedule has been changed for the reason that Lightspace team has managed to attract global players also for early product validation phase. Validation process will be continued by repeated project activities with another global healthcare market leadear in robotic navigation systems. Several automotive manufacturerd also has been attracted to start validation phase of our product – task execution has already been started.
IP Management work been executed extremely productively with filing of 6 new patents.
During project first half team filed 6 patents enabling freedom of operation into new technology area further improving existing technology.
Several validation tests carried out with global leading healthcare technology providers in surgical and specifically robotic surgical navigation have validated superiority and uniquness on market with companies multi focal near eye display technology.
Team expects to complete pilot testing with products and lounch of manufacturing at the beginning of Year 2022. High image quality near distance AR visualization headset would enable number of enterprise applications and especially would make impact to hoe varios medicla procedures will be carried out.
