I'm sorry but you obviously have no experience with augmented reality (what you are actually trying to do). There are so many problems with your approach...<p>1. In order to be able to render virual objects on top of the real image (camera image or directly to the retina) you should know the pose of the eye with respect to the outer world. For example if you are a surgeon and want to overlay an MRI scan on the patient, you need to know the pose of the eye (camera) in respect to the patient and this is a VERY hard task as everybody doing computer vision can tell you. You only mention how to find the pose of the eye with respect to the head but this is not enough.<p>2. Processing large 3D models like 3D scans requires a lot of computational power. It won't be very portable.<p>3. You will also need a depth image along the camera image in order to achieve some of your goals (like bluring the image according to the focus distance). Do you have any idea how difficult this task is?<p>You have cool ideas, but should be more realistic about your goals. Also reading some things about augmented reality and computer vision will help you a lot to understand how difficult this is.
Cool project, but the intro on Kickstarter is grossly misleading. It implies that you have a way to obtain the data about what should be rendered in addition to projecting it, when in reality this project is only about the projection part. It's not bad to talk about potential applications, but you're implying that they're part of the project when they're not.
All that is mentioned here so far as I can see is a method for getting focus information coupled with a virtual retinal display. How are they proposing to get the image on the other side of the arbitrary thing you are supposed to be able to look through?
