| Kudan | We are accelerating the evolution of Virtuality (AR/MR/VR) and Robotics (automobile/drone/robot) by developing computer software algorithms classified as Artificial Perception (AP).Over the years Artificial Intelligence (AI) has become the backbone technology for machine vision, however it only consists of functionalityequivalent to the left-side human brain, such as learning for semantic extraction.On the other hand, current machines are extending their capabilities from closed virtual worlds to the real-world, which requires the right-side human brain related to instinctive geometric acquisition.We are working to fill up this missing piece by developing AP algorithms that are the machine equivalent of the right-side human brain. Our AP complement AI, by providing 3D and kinesthetic senses to the machine to access the real-world, for virtual-real mixing and robotic control. With the combination of AP and AI, machines are getting closer to sensing and interacting with the world like we do, utilising both the left and right side of the brain. | $28.8M |  | Jul 02, 2016 |  |
