Nah there are studies that show that if you go blind suddenly you will start to learn decent echolocation within a few hours, meaning in a room they've never been in they can use a clicker and not walk into things. You can already do it you just haven't ever done it consciously. It's your phone.
No for real. You can do a 2-second Google search and find a bunch of studies showing that humans can learn to do it very well within a 10-week course of 2 hours a day. But I know there is a video floating around of some students who managed to prove that even within just a few hours of training test subjects did remarkably better navigating a room using clicks whilst blindfolded then they did before the training and with no clickers. The research speaks for itself. You already have the skill in your brain and you're using it all the time when you move around in the world, you just don't consciously realize it. It's why you have two years instead of like one big ear right in the middle. Your brain can discern the difference in sound from one ear to the other and use it to triangulate the source of the sound and sources of reverberation and echoes. I'll see if I can dig up the video.
I can't seem to find the video. It was some research college and the experiment was to see how quickly humans could adapt to echolocation after being blinded. So you took regular people and put them in a room about the size of gymnasium with a bunch of lines and marks on the floor, They had a bunch of generic shaped furniture like from Ikea that they would move around the room using the different marks for the different tests, and one of the tests was to just take a group of people and leave them in this dark room for like three hours, walking around bumping into everything, then they move all the furniture and bring the subjects back in, and the collisions with furniture drops way off. The camera angles from the study are shot from above and shows I believe groups of two trying to navigate. It may well have been the study that showed it took 10 weeks and my memory is just not correct, but I have a very specific takeaway that was just a few hours the results are not only measurable by stark.
Very definitely documented cases of blind people who are apparently masters of echo location, most use a hand clicker, their mouth to click, or taps with a cane.
Standing on the bus stop, so, uh the road? But that wouldn't be useful without the buildings and all the activities in them that bring people here. Or since the room could be considered the general "outdoors", oxygen, or stuff like that.
The chances of the most useful thing in the room being my phone is pretty high no matter what room I am in, since my phone is usually in my pocket and also modern phones are one of the most useful tools in existence.
Depends on purpose. We’re complex creatures. Sometimes we need food. Sometimes we need to stay warm. sometimes we need to battle the dark thoughts in our head.
My computer. It was the most expensive one in the store when I bought it, and besides a not so great wi-fi adapter and ageing HDD's, this computer's been amazing for gaming sessions! The only physical console I've touched in years has been the Nintendo Switch due to the exclusives.
I'm out in a gazebo with nothing around me, so probably the sleeveless argyle sweater which is doing a better job keeping me warm than my blouse/skirt.
Arguably. Though I could just use a hole in the ground. I'd say the sink is a close second. If I was in the wilderness and I needed to choose one though, I'd choose the toilet paper.
My job occasionally takes me out into middle of nowhere unmanned industrial facilities. I keep a roll of toilet paper in a plastic coffee can, because these facilities usually don't have facilities.
I'm rocking in a hammock in my backyard, while the portal solar panel I got for camping charges my bike battery. The sun is definitely the most useful thing right now, giving me next week's commute!
Want to sit? The chairs. Want to see? The lights. Want to not fall under the building? The floor. Want to get out? The door. Want to swim? The pool. Want to get out of the pool? The ladder. Want to get changed? The changing room. Want to warm the room? The heater.
Uhhhh. Probably the fridge. Maybe the microwave/oven combi, but the microwave no longer works so it's a bit less useful. If you purely look at the basics of survival then those would probably do it. Maybe the heaters, because surviving in a cold room is also pretty shit.
You could also argue that the smartphone I'm typing this on or the laptop are the most useful. It really comes down to semantics of "useful".
My iPad. I can not only doom scroll Lemmy, but keep up on news, read, play music or video, consume all the worlds knowledge. Also I can order food or anything really
