How much computing power and memory for the library and software... How much difference in the camera from standard detectors, lens materials.
How long until all the smart phones are reporting environmental background chemistry to whoever on demand, or just continuously.
Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.
Anatol Rapoport was a Russian-born American mathematical psychologist (1911-2007).

I was also curious about the footprint of the library and the API. but their SDK for the standalone detector using BLE is $499 USD and will not ship
for 6-8 weeks.
I looked at their patents but didn't see anything related to what type of processor is used for detection. My guess would be a dedicated DSP but maybe
they are able to run their detector using SIMD instructions.

Interesting you mentioned that - Consumer Physics has a patent for monitoring the food consumption of a person.
Wearable Spectroscopic Sensor to Measure Food Consumption Based on Interaction Between Light and the Human Body
Ideally there would be a option to enable/disable detection.. But you never know about those firmware engineers! ;-)

In the link the phone says "Scan Body Fat ... Creating Spectrum"
Then it turns over so you can't see the screen.
ROFL !
Edit:
Got to get me one of those before they change the programming.

I have much doubts about this...
How can the device emits medium intensity light onto an object surface and determine the chemical content inside the object? It works on mars because
of laser ionisation and vapourization of matter.
Usually spectrometry works with light passing through a material (absorption) or under a specific angle (emission).
--> The sugar content of an apple (usually made by refractive index/brix meter of a slice) without direct view of the juicy part...to my knowledge
the skin of an apple doesn't contain any sugar...no sugar taste if you don't bite into it!
--> The chemical content of a drug/med pil without visibility of the inside and only by interaction with its outside seems also stange because most
pils are coated with products (colourizers, gels, polymer, sugar, ...) that have nothing to do with the internal active ingredient.

NIR can penetrate into the sample a little bit. At work, a colegue has bought a few SCiO sensors to compare their performance to other methods we use
(mainly LCMSMS, GCMS, Raman/IR and NMR) and to 'play' with. Preliminary tests indicate it is capable of distinguishing between pills and sometimes
able to identify the active ingredient but coatings definately impact the result.
