The sophistication and power of our micro-processor controlled, high efficiency high output LED flashlight front ends is
NOT matched by a correspondingly sophisticated and capable control surface. This is a huge problem.
Back when I was predicting that Apple would release something like the iPad, there were two posts about the
MacBook Wheel, which is a satire by The Onion about how Apple has the tech world buzzing with its move to do away with the keyboard in favor of a giant wheel and button combo (like the iPod). In the video, one Apple representative says:
"At Apple our philosophy is to create products that are simple to use. And nothing's more simple than a single giant button."
Yuk yuk yuk. It's a freaking riot. As if making an interface
simple makes it
simple to use. Although, it actually IS simple to use--but oh so painful. The person demonstrating in the video takes forever just to navigate and accomplish things. It's funny because it's ridiculous. Because forcing all the complexity and sophistication of the input (text, file structure, file names, programs, actions, screen information, cursor location, etc.!) through this interface is ridiculous!
But this is exactly what I think of when I see all these flashlights with multiple levels and multiple modes all trying to force them through the bottleneck of a single clicky switch!
A simple interface is only appropriate for a simple function. A single level light mates well with a clicky switch or a SureFire type lock out tailcap.
A dual level flashlight mates well with a progressive twist switch like the SureFire A2/L1/L2 LOTC or with McGizmo's Piston-Drive.
But, beyond that, I think you run into trouble! My favorite single-clickie UI for a smart light is McGizmo's 3S scheme where a short off time is used for switching levels. But I still think it's a workaround for the overly simple single-clickie
UI bottleneck. And
we need to remove this bottleneck.
We all need a more sophisticated and elegant control surface for our flashlights!. And the technology is already there! Has been for a long time! Remember this product?
I do. It was Christmas break and my sister and I were both at my parents and she took about 5 seconds or so showing me the basics of how to work the ipod, then just handed it off to me. I was blown away. It was incredible. Anything I intuitively thought should work in terms of controlling or changing stuff with that UI just ended up working that way. I was like "Oh, this is why people are so impressed with this thing!" It was a seriously awesome UI. It was complicated enough, but no more so. And it was intuitive and easy to use.
Adding extra buttons to a flashlight does not improve the situation much over a single clickie! Adding a rotary dial or selector ring, like HDS Rotary or Spy 007 or NiteCore SRT models is going in the right direction, I think (especially the Spy).
But what would really excite me--and what I think is absolutely necessary for the more complicated light front-ends--is something like the iPod controller, but in a single tail-end touch surface--like a laptop trackpad. Like the Apple trackpads, actually, in that pushing in will cause the whole thing to click, which is registered (or can be) as different than a touch.
So . . . imagine it. Push the rear touch button in until it clicks to wake the light up from OFF (and it's been off so there's no parasitic drain). At this point, simply touching the rear switch-pad gives you momentary on in the scheme of your choice (last level, always low, always high, --whatever).
Want to make the light brighter? Rotate your thumb or finger clockwise--just like raising the volume on the old iPods--and you get increasing brightness. Could be in jumps, could be continuous--whatever. Rotate counter-clockwise and you get decreasing brightness. For mode changes swipe straight down or up--assuming there are mode changes (like flood vs throw a la SureFire A2 or LunaSol 20).
For constant on, push in further to click.
And you could add a capacitive touch strip or surface or ring to the head or up near the head with a similar scheme. You'd need to have a more sophisticated connection of the head to body, however. Think a camera lens. Used to be there were very fine threads and you screwed your lens on. Until some company came up with something better. Then later, electrical connections were added, then more. Now, with a quarter turn you mechanically and electrically connect your lens to your camera body and get autofocus and all sorts of control over and information from the lens.
But what do we have with flashlights? Eh? Only a screw on head. But if we had something more like a camera type connection, then we could separate out the body from the electrical pathway--which is what the Piston-Drive also did and is part of why I loved it so much. Don actually made a PD light with a plastic body once, he told me! LOL! Point is that you could use electrical connectors or contacts and cabling for the circuit path and controller interface connections. And the body material could be chosen for other reasons. I'd love to see a magnesium alloy with some kind of surface coating. Again, think camera bodies. Plenty of magnesium ones out there.
The point is that we're way WAY behind in terms of the UI (and body) for flashlights. They freaking SUCK to use. They are so inelegant and so annoying. Just like Greta said at the beginning:
And see... I wish we could see the "re-birth" of simplicity. Two modes - high and low. No programming, no click five times for this or that or stand on your head while turning the head three twists to the left then two to the right, blahblahblah. KISS - keep it simple ******. On - off. One hand operation.
The feeling of "simplicity" is when the user interface is appropriate to the reality with which you are interfacing. If you need to TYPE a click wheel is a nightmare! And if you have multiple levels and multiple LED's and multiple modes, a single clicky switch isn't great either, even with the best schemes for switching. And we don't need MORE freaking switches! We need something elegant!
There's a reason why all modern smart phones are using a touch screen interface now. Why can't flashlights?
I was talking about this with SilverFox today and he pointed me to this review:
Imalent EU06 which is a flashlight with an actual touchscreen! LOL! And I like that this is getting outside the box, so to speak.
But it's not appropriate for a flashlight. A touch screen is too complicated and uses too much power and is too big for a flashlight. Plus, you need an interface that you don't have to
look at in order to use! If you're using a flashlight it's because you want to look at
something else. So I think the right degree of sophistication is a capacitive touch surface interface--something like 9 sensors--one in the center and 8 around the outside--that would probably be about right. And this kind of thing is readily available and small and inexpensive. Or it could be a lot more sensors than that if you wanted. That's the stuff under the hood. The idea is the same. To take simple gestures and map them to appropriate functions. And if you already have your thumb on the rear activation surface, or another finger(s) at the front surface, then it's easy and simple to manipulate things with them via simple gestures.
And imagine only having to grab the head of your light to make it turn on! Let go and it turns off. (assuming it was in momentary mode and ready and waiting).
Because, once again, I think it's important that after a certain amount of time of inactivity, the touch uC would turn off and thus stop the parasitic drain.
Anyway, this is all just one vision of how it could be implemented. There are many others. And it's easy to imagine a bluetooth connectivity (mentioned earlier) with an app on your smartphone so that people could customize the heck out of the implementation to their liking. But however it is implemented,
we simply desperately need a better, more sophisticated (but still elegant) UI.
That's what I want to see. That and more truly High CRI emitters, like the Nichia 119 and 083. I see all these lights all using the same Cree emitters, and I'm like, yeah whatever. I feel the same way about them (to a degree) that I used to feel about the 5 mm Nichia white LED's back after the Luxeon Stars had come out. People at work who knew I was into flashlight would show me all their lights that they picked up for super cheap at the dollar store or at Home Depot or wherever, and they were always using multiple 5mm Nichias, sometimes in a beehive type configuration. And that was fine. And I never rained on their parade. I was always positive and excited for them. But at the same time, I was always glad of my Arc LSH with the Luxeon Star.
And that's how I feel now after having lived with the High CRI Haiku and the SunDrop. Those beams really freaking excite me! Nothing against the Cree's at all, though! It's just personal preference. I value high CRI over output. It's why I carried the SF A2 for so long and why I was into incans. But now LED's have surpassed incans in terms even of color rendering. Or they rival them, anyway, at least. And with greater efficiency and way greater longevity.
It's exciting. And I don't see very many high CRI LED lights. I mean, some say they are (with like an 80 CRI) but that's really nothing special. 90-95 CRI on the other hand combined with 4000+ K CCT? Now that gets me excited! LOL!
YMMV. Just my personal preferences.
