Hi there. I need an app that mirrors the screen of my android phone to use it as a HUD in my car. I've already found an app that shows the current speed mirrored, but i would like to have it for other apps, too. So that i can use apps like Google Maps Navigation with my front window.

I googled a lot, but i sadly didn't find anything...

if i understand Phexi right, he wants to put his phone under the windshield in a way that enables you to see the reflection of the screen in the windshield. works great during night trips.

usual problem - everything is mirrored.

This is exactly what i wanted to tell you :)

Yeah, the "evrything is mirrored" can be a problem, but with the help of a homescreen widget (maybe with a mirrored text :D) it should be possible to switch back very easily

With an AMOLED display it should look very good (when the rest is black), but it has to be mirrored to work.

should look like this then

I think 5 is enough. Any of these float your boat? (those all *should* have mirrored "HUD" settings so when laid on your dash under your windshield you get the effect of the BMW HUD above. I haven't tried any of them personally, though.)

He isn't looking for a speedometer, he wants to mirror his screen for all apps, so that way he can use the maps app or the navigation app or any other app of his choosing and see it on his windshield. Before you go off on your next pissy fit, read carefully.

Wow... feel better?

You are right, I didn't read carefully - I read looking for a HUD, scrolled down saw more HUD talk, more talking of speedo HUD's, so I wen't on appbrain and looked for some.

Just trying to help. I guess this another forum I'll stop contributing to. I don't need to deal with know-it-all jerks like you, I get enough of you people in real life.


Sorry OP, just trying to help. I don't see any way to do it unless you made the OS and all the apps (at least the relevant ones) mirrored in a custom ROM.


Goodbye.

Any progress on this? This would be an excellent app idea but due to my limited development knowledge someone else will have to work on it. This app will allow anyone to use their phone/tablet to project image on a semi-reflective surface and serve as a cheap full-screen navigation/media center solution.

I will be willing to purchase it as an initial customer and even make a small donation for its development.

No, the app in the link only mirrors some text based info. We need something that can flip the display contents on the y-axis. This way when you project the screen contents the reverse text and graphics appear normal. I do not believe there's anything in the market that currently offers to do this.

    Good app but need to adjust too much. Need to automate the adjustments to make it user friendly.
    I totally agree that the setup is a bit of a pain, and I have an idea on how to improve things, but it's also not particularly nice, and might not work all the time. (It involves creating a new, simple app to run it in the other half, to calibrate the main app. Then I could see exactly which part of the screen is taken by Half HUD and which part is used by the app you want to project.)

    Also, I don't expect improving this would dramatically change the adoption, which is at a grand total of 21 users after it peaked at 23 a few days ago. My question is: After taking the time to set it up, is this something people actually want to use? How many?

    Anyway, when I find some time I guess I could try the approach I described above, to see how well it works. Or, does anybody have a better idea?

    i have been working with custom apps development for work, and I think (I HAVE VERY LIMITED KNOWLEDGE DONT QUOTE ME AS AN EXPERT OR CODER) you are right, this should be a one-button widget/one-option setting under 'settings' of a ROM, not an APP, that simply reverses display on the Y - axis (hell, option for x-axis too, don't know if vertical or landscape display wanted/needed, especially with tablets), reverses control functions, and control locations. (ESPECIALLY ICS controls)

    My understanding of coding for this, you can't have an app that would effect the output of another app, the only 'system wide' apps, like 'Screen Filter' for example, can control a system-wide "overlay" but not change the actual output of display options.

    I am only posting this because we had the same issue come up with something hella specific we were working on, an education in-house app, needed a left-hand and right-hand version, and at first were thinking some kind of library call to either mirror or flip just a specific layer of display within the app, but it turned out it was much much much much easier to just recode a 2nd location for the controls and set it under options within the app to choose which one to use, the 'mirroring' i think proved to be impossible without a custom rom, which most of us would've been ok with but can't add new people or expect to have enterprise control of the app if it was a rom change. See, if you mirror the display, the touch controls work opposite their button location. If you mirror the control buttons as well, the functionality of Left Right becomes reversed too, essentially breaking the app. (think of the old helicopter game controls, only left right instead of up down)

    but, not only for HUD, but for left-hand/right hand, disability access, and other various uses, a ROM-wide setting to control reversing the display of both controls layer and app-display layer would be most excellent for custom roms and eventually the Android core code as well (Here is the problem everyone in this thread is ignoring, if the display output is simply reversed, your touch controls, especially for ICS system buttons, functionality would be broken, controls in the dead center would work backwards and controls on the left or right side of axis would still work on the opposite side of where the display shows the button to be, and this would, for the common user, essentially break functionality of the phone itself) --- Am I making sense? someone who is a better developer should be able to rephrase what i'm saying in a better way.

    But the app controls would also need to be reversed, and I don't think that can be done via an app, at least not to control the behavior of other apps. An overlay wouldn't work, even if it was a mirrored output of display over a blank overlay of the original display output, because control options can't be manipulated by an additional app for the app you are actively using.

    But i agree, this should be easy enough to do for CM10 and other custom roms.

    I would just suggest you separate the two within settings, so there is an option to reverse controls only (for left handed, disabled, special situations, etc -- which should really be included in Android core itself) for accessibility, let apps call on the control layout option so can just code once and have it reverse A) location, for handedness, B)functionality, for special use, options, and HUD, and then C) also reverse display, for either HUD or Mirrored projection/video output/special uses. So, if I understand the android programming correctly, you just need to include 3 separate reverse-output libraries for app programmers to call, which could also just be set system-wide within options, they are 1)reverse touchscreen control location based on a flip of y-axis or x-axis in landscape, 2)reverse touchscreen control functionality based on the gyroscope-detected axis, and 3) reverse the display rendering output along the axis, also gyroscope-detected.

    I guess I would suggest begging CM folks to incorporate this, and once its in use with enough people out there, maybe by the time Android is at Sweetbread or Truffles it will be incorporated into the main libraries. Either that or a group of disabled and left-handed folks (NOT IMPLYING THE SAME THING BETWEEN THE TWO GROUPS PEOPLE, I HAPPEN TO BE LEFT HANDED MYSELF) sue google class action to include these in the programming libraries under the disabilities act violations for accessibility.

    ----

    of course, if someone else knows a much, much easier way to do this with just a standalone app, please speak up!!!!!!!

    not that I've found. you'd think mirroring the display on the y axis would be simple. I'll make it of I ever learn java/linux/android programming

    Do it physically. Make a holder that will let your phone sit upright with a mirror in front of it angled 45 degrees. Now the windshield will show the mirror image of the mirror; ie. not backward / upside down...

    Of course it would be tough to actually USE the phone... maybe voice commands? :)
