I study photonic engineering. My current main interest is in physical phenomena, including Fourier optics, holography, light sources (e.g. lasers) and optical components (e.g. LCDs).

What do you think of a non-invasive brain interface?

Preferred programming language: C/C++
- Once I learned something about OpenCL, OpenMP, Qt,.....
Favorit operating system: Xubuntu/Win/Mac -> Cross-platform

Favourite musical instrument: Didgeridoo

Nice to be here.

@MaxDH hello and welcome to the instance and community! Thanks for the TED talk also, I have yet to watch this video and hopefully I'll get a better understanding of some of the things you're interested in. Can you share some of your thoughts on as it relates to spacial computing (i.e. Magic Leap)?

Thank you for the warm welcome =)

My first thought was, how does the display work?

I found a patent from Magic Leap, Inc.
Maybe the Magic Leap One works like this =)

In order to obtain a real 3D image, it is necessary to create a light field as if from a real object.
This can be done by modulating the wave field, e.g. as a sphere, Fig. 2A[pat].
When we "see" such a spherical light field, it looks as if it comes from a (virtual) point source.

The patent describes the stacking of the light-guid optical elements to a 3D display (WRAP), see Fig. 5A[pat].

By using a beam deflector, any 3D pixel can be addressed. The result is that the calculated virtual environment can be projected into the wearer's eyes.

Some interesting points of the patent
- Section 0034: limited number of slices of a 3D volume ("...less than 16 to 36 or more...")
- Section 0036: How is the light field generated?
- Section 0048 ff: WRAP device
- Section 0052 ff.: How the WRAP works (in particular section 0055f)


Please correct me if I’m wrong.

@MaxDH We just added emoji for most of what you listed :) should tell you how well you will fit in here :)

:cpp: :xubuntu: :windows: :rainbowapple:

@MaxDH Welcome here! I'll give a look to the TED later =)

@MaxDH I just watched the TED talk. That kind of noninvasive brain interface is amazing! I was blown away by the medical imaging she was showing, but what could potentially be done with that for things like prosthesis development really is fascinating to me. I'd love to see how far she can take it. I'll definitely be keeping an eye on what she does from now on. It ties in closely with my own areas of interest.
