> Humane’s projector lacks color and grayscale depth. Humane’s display a monochrome cyan (blue-green). There is no ability to even highly anything with color. Secondly, they demonstrated very limited grayscale depth; they showed just “on,” “off,” and a half-level. Even if grayscale is theoretically possible with the Humane projector, the ability fo see a grayscale image is severely hampered by using skin as a screen and the lack of contrast due to ambient light.
Not to mention blue is the hardest color to see already. These people are idiots.

They should have more than enough brightness to be clearly visible in those light conditions on almost any visible wavelength they chose for the laser, so it's weird if they optimize for this instead of the outdoor performance.
Is this ready to use? No. But I'd like to point out what may be novel UX ideas here that are worth improving on.
* raise your hand in front of device to activate the projection
* move hand to increment/decrement a number
* close hand to tap
With image recognition, other gestures with the projection hand like tapping fingers or touching the image with the off hand would allow other interactive inputs.
I’m personally impressed by how you navigate the radial menu by tilting your hand as if you were balancing a marble. With some improvement, this would feel very intuitive!
