Shoot lasers from your wadded up Napkin or Jeans

 While not drawing attention to yourself or holding anything; prosocial uses include holograms and romantic tree-name carving, mosquito zapping, QR code reading, and wellness spectroscopy

Just a prosocial, mutually enjoyable variation of [KDF]'s idea [link].

My first thought was "Shoot lasers from your ice cream"; you could just carry an ice cream around, and it would have a laser, a coneful of batteries in it, and a little quarter sized display on top. It does track your eyes, just like [KDF]'s invention, but also puts a separate very low energy laser listener on your throat so "subvocalizations" or commands to the laser can be made that are inaudible to others.

So, you subvocalize "funny meme hologram", and the hologram of the funny meme hangs there in the air above the girl you'd like to talk to but are perhaps shy around.

As things proceed you dare to use the "laser carve names in a tree" energy setting, on occasion, it's easier to look at a QR code or object and subvocalize "Bing, look that up!" (your phone then gets the data). Some people might get rid of mosquitos near their face as well.

So as wearable computing and lasers go, it's a toss up between a wadded up napkin (you can carry a wadded up napkin anywhere, for some ice cream, for others a vegieburger), or actual garments:

Shoes: These contain an ultrasonic transducer (or maybe ThZ) that can see what your eyes are pointed at, even though they are through-body; the shoes, or your cargo pants contain 2020 batteries (or better)

Country western, or petite chic belt buckle or Levis Top Button. The levis top button contains 40x bright lasers, and a 360 fisheye lens or better, a plural digital waveguide array. Now everybody knows things look terrible and dim and far off at the edges of a fisheye lens which is why you use the 40x IR night vision strength laser, and the 1 cent alibaba 32 bit CPU to remove distortion from the video. There are several other festive lasers on the button like hologram makers and tree carvers.

If all that research on Ultrasonic vertical body imaging socks worked then your shoes, and maybe or maybe not your belt buckle or pants button can see what your eyes are gazing on. The ultrasonics can easily see you move your tongue on your teeth (keyboard) 3-5mm at a time to type on a 32 location keyboard; if The ultrasonic socks work really well they can see your throat subvocalize.

If you carry a purse you can use .5B Plaid Conductor (RAIC) to sling it on any shoulder, anytime, at a conductive garment and have it be full of batteries that autoconnect to the system.

That brings this idea to sort of the *only new idea content here*, and It could matter:

Lets say you want to stand outside and "pee-angle" a hole in the concrete with the pants-buton laser and drop in a tree seed. The reflecions/retroreflections of that could be dangerous to you or others. Now let's say at first you assume an array of laser dots the size of a period . and extremely powerful, and you put :: that is # that is 121 of them next to each other at a grid. This is no ordinary 121 element array, just like a dot matrix printer each of the dots is activated sequentially (raster, asterisk, etc) and momentarily, but at very high power.

You are turning a big diameter hole drilling laser on just one, very micro-micro-dot on at a time. Then to sort of swab out the tree-planting hole you just rotate the ::-># laser microdot array and the individual little holes they make smear into each other.

If you've got an alibaba 2c 32 bit processor checking the camera 1000-10,000 times a second, you can look at everything in the fisheye lens/waveguide array. To watch you and the people near the tree-planting aperture you are making.

If the CPU sees a stray reflection in a person's eye, a specular dot of any kind at any location, it can turn off the laser. The thing is, this is so fast only a micro-micro-dot 1/121 of laser tissue area contact occurs. The laser accident is 121 times less injurious and probably undetectable. That is much safer than if you had been swabbing away at the concrete with a gigantic O 3-11 mm solid beam all at once.

The 121 times less risky safer scanning micro-micro-dot drilling laser is new to me. All that it requires to be as speedy at drilling a hole as a big O laser is to be 121 times more powerful.

       Shoot text from your (my) computer into the mainframe using a keyboard - prosocial uses include receiving fish croissant sandwiches for prolific output. Much food for thought, to be sure, especially that part about pie angles, but one possible issue is the difficulty of projecting a well focused spot with a very small lens (Airy limit).

       [snictown] I'm reading up on the Airy disc now. (At first thought it was the Abbe effect).   

       At Wikipedia [link] I found out that light optics had (various ways) surpassed the Abbe limitation.   

       The current highest resolution light microscope is not, as I thought was "just the way it goes" 400nm it is a light microscope near 50 nanometers.   

       I'm not sure what that says for the 360 degree fish eye lens Jeans button, compared with the optical waveguide Jeans button, but it is encouraging.   

       Also, There's a great performance enhancer to Shooting lasers out of your ice cream/napkin/jeans: Contrast enhancers. I could wear comfortable contact lenses loaded with Something ultrasound really likes to see, like maybe, an outside-the-pupil area annulus tuned to ring like a bell when stimulated by sound of certain scanning frequencies. I read ultrasound has a 50 micrometer resolution at tissue these days.   

       Alibaba has dermal filler (hyalonuric acid) needleless-airjectors for $14. you could airject your tongue with a little interior tongue-tip blob of some special polymer ultrasound contrast enhancer. 1-2mm large at the underside of the tongue. That way your ultrasound reader shoes could have something much easier to see when you do keyboarding with your tongue.   

       The WOW part:   

       One of the most exciting things I read today was this kind of long thing from wikipedia[link]. It's great, enjoy!   

       "Structured illumination microscopy (SIM) enhances spatial resolution by collecting information from frequency space outside the observable region. This process is done in reciprocal space: the Fourier transform (FT) of an SI image contains superimposed additional information from different areas of reciprocal space; with several frames where the illumination is shifted by some phase, it is possible to computationally separate and reconstruct the FT image, which has much more resolution information. The reverse FT returns the reconstructed image to a super-resolution image.   

       Although the term "structured illumination microscopy" was coined by others in later years, Guerra (1995) first published results[24] in which light patterned by a 50 nm pitch grating illuminated a second grating of pitch 50 nm, with the gratings rotated with respect to each other by the angular amount needed to achieve magnification. Although the illuminating wavelength was 650 nm, the 50 nm grating was easily resolved. This showed a nearly 5-fold improvement over the Abbe resolution limit of 232 nm that should have been the smallest obtained for the numerical aperture and wavelength used. In further development of this work, Guerra showed that super-resolved lateral topography is attained by phase-shifting the evanescent field.   

       Or to put it another way,   

       Exciting: "(SIM) enhances spatial resolution by collecting information from frequency space outside the observable region. This process is done in reciprocal space:" I think people that like casual extra dimensions of nature in usable physics would just be saying, "Sim microscopes and hypercubes".   

       Can you do SIM with water waves and sound waves? How about wavelike periodic phenomena that are sort of like recurring sinusoidal distributions (Fourier systems)? Can you look for SIMlike phase spaces in data, like the internet, or corporate data mining and do something useful with the information?   

       contemplating a, non-time mathematically revealed (phase) dimension, hanging out in a SIM then, just analogous to the way cutting a mobius strip down the middle makes two interconnected rings, what does cutting a SIM down the middle do?
