> most tasks we achieve via computers and phones do not strictly require a screen.

X (doubt). There are unfortunately only 5 senses that our brains can interact with the outside world, and visual ways are the most information dense and the easiest to utilize. The screen isn't going away anytime soon.

Projector to me are same as screen - they've been around for as long too.

Though I do look forward to direct computer-brain interface, like introducing a 6th sense.

Projectors really love flat, non-moving surfaces. Will be interesting to see how they've coped with a wiggly hand wiggling around or in motion.

I highly doubt this thing is even usable outdoors. You would need pretty insane brightness levels for this to work in the sunlight. Companies have been trying to make projects with touch input for years, and nobody has gotten close to anything resembling a consumer product, I highly doubt they achieved it here

[gizajob]

I agree, even though I'll reserve judgement until trying it. But it remains that limitations in power are unavoidable, and projecting a laser image onto a hand in daylight is going to use an awful lot of juice, particularly given the projector is so tiny I've no idea how this can be done so it's functional, nevermind "insanely great". Same goes for their claim that the speakers inside this tiny device are worthy of getting sound to the ears while skateboarding outdoors. You can have all the Head Related Transfer Functions in the world but again, you need speakers and amplifiers on the order of several watts to get the sound up to the ears. My iPhone Pro Max sounds great and loud in a quiet room, but take it onto the street to play music, it's barely audible. Also not sure how the device will know what kind of HRTF to use given its placement is going to vary so much.

The 5 senses thing is long-disproven rubbish. Humans have hundreds of senses.

[Aperocky]

Would love to hear what the rest of those are, please be specific.

[TylerE]

Well, for instance, what is commonly referred to as "touch" is actually a whole bundle of senses. There's the actual sensation of pressure, but also texture, temperature, surface finish, the physical position of your various body parts, your sense of balance, etc etc.

[paledot]

Okay, but unless you're suggesting a computer interface based on proprioception, I'm not sure that that's relevant to the topic at hand.

I too would be interested to see an enumerated list of over 100 senses.

[TylerE]

Isn't that what all the various VR glove type controllers are?

[paledot]

No, but points for a solid attempt. Senses are input (to the body), not output. Glove controllers are just output via movement, just like keyboards and touchscreens.

True, part of what makes them cool is that your proprioception more or less agrees with the virtual hand that you see in your headset, but that's just window dressing. The computer has no way to control that.

[albedoa]

Can't help but notice that you again didn't answer the question. I will third the request.

[chagen]

Ok, 100 senses could be too many for you to type. Maybe could you list 20 human senses?

[Aperocky]

I mean you can separate a screen out into a bunch of pixels as well, or specifically blue, red, green pixels.

Even on the vision front, we have rods and cones that works differently to generate ONE vision.

This is entirely semantics.

[sassifrass]

Not sure there are hundreds, but just to add one example beyond “the five”: Proprioception [1]
