Most night-flying bats make distinctive ultrasonic clicks when flying.
The proposal is for a set of augmented-reality goggles equipped with four microphones and audio processing equipment that can locate multiple bats within the wearer's field of view and display moving bat symbols in different sizes and colours according to the estimated species of bat (the squeaks are unique to each species); it is even possible (although difficult ) to identify an individual bat by its unique "voice".
That is all.-- 8th of 7, Sep 20 2019 Bat Sensitive Sunglasses https://www.youtube...watch?v=F-u9lnhx_Hk'Your mad' [Skewed, Sep 21 2019] Won't this produce a long string of bat images like a string of sausages from where the bat emits it's sonic chirp to the point of impact with a solid object then back to the bat & beyond? In fact not just a string but an expanding cone.
Three or four bats flitting about back & forth are going to cause you glasses to go black with overlapping bat images in all directions throughout your field of vision.
Congratulations! you just invented sound activated sunglasses, worn at night [linky] [+].-- Skewed, Sep 21 2019 // a long string of bat images //
No, it doesn't have "trails" - just a little image of a bat (or bats) that moves as the software quadrangulates on the strongest source with that "signature'.-- 8th of 7, Sep 21 2019 //No, it doesn't have "trails"//
Disappointing.
The //Pure entertainment// value (of watching wearers, maybe even carrying a few bats for release in their presence at opportune moments) has (for me) been severely curtailed.-- Skewed, Sep 21 2019 // Disappointing //
Well, you can turn that feature on if you pay for the software upgrade ...-- 8th of 7, Sep 21 2019 That's what they told Sturton. "Lifelike" the advertisement said. "Real Hair!" they said. "Speaks over 100 phrases" they said. "Voices other than Simon Cowell are available at an extra cost", they did not mention.-- MaxwellBuchanan, Sep 21 2019 We never got a chance to tell him. We only got as far as "All bodily orifices fully functional" and he threw down the payment, grabbed it and ran.
He never even came back for the free extra set of batteries or the complementary bottle of water-based no-stain lubricant... he's quite weird at times.-- 8th of 7, Sep 21 2019 What do you mean, "at times"?-- MaxwellBuchanan, Sep 21 2019 Well, when he's awake, and most of the time when he's asleep except when he's actually unconscious through drink. Then he's just repulsive.-- 8th of 7, Sep 21 2019 ^> sp: goggles-- wjt, Sep 22 2019 Hang on a moment.
What we're talking about here is some glasses that can hear frequencies you can't hear because they're too high, and then use that information to project symbols representing things you can't see because it's too dark.
If MaxCo. decides to implement this, our first move would be to cut out the microphones and sound analysers and simply display plausibly-moving symbols. An advantage of this is that our goggles will enable you to see a much wider range of bat-species-symbols.

And some claim the old skills are dying out. No wonder your family's done so well over the centuries ...-- 8th of 7, Sep 22 2019 //engineered to separate the gullible and credulous from their hard-earned money// No, we can't do gulls. Just the bats.-- MaxwellBuchanan, Sep 22 2019 That will probably Tern out to be a good thing in the end.-- 8th of 7, Sep 22 2019 random, halfbakery
