One of the key elements of any eccescope is its display module — the part that actually directs images into your eye. Light doesn’t bend around corners by itself, so the question remains of how to direct those light rays into your pupil. One possibility is to take the concepts suggested by the Brother Airscouter, and push them to their limit. Here is my visualization of how such a display module might appear:

What is going on in this visualization is that components within the earpiece (not seen in this image, because they are blocked by the head) are generating a tiny collimated image that is directed to that little optical deflector you can see positioned in front of the eye. Different parts of this generated image are deflected by different parts of the optical deflector into the user’s pupil. The result is that collimated light rays enter the user’s pupil from different directions.
Like the Airscouter, this is a form of “retinal display”, since the user’s eye is left to do the work of converting those light rays from different directions into an image. In a retinal display, there is no physical display screen, just a virtual image that appears to be floating out in space, similar to the virtual image that you see when you peer into the eyepiece of a microscope or telescope.
With the proper engineering, a display module with this form factor is perfectly achievable. In fact, it might even be possible to create a display module that is even smaller. But there is more to an eccescope than its display module. It also needs to track — with high speed and accuracy — the user’s head position and orientation. Also, it is useful for the eccescope to gather information about what the user is looking at.
More to come.
