1) Cool! Mediocre minds think alike. This was my conclusion as well. If we can't directly mirror / fip / rotate / translate android or video drivers... perhaps a VNC / RDP app with flip / mirroring is easier.

2) as to the difficulty to control tablet on dash: I have found voice controls and a bluetooth mouse such as this one:

http://www.ebay.com/itm/HP-MoGo-Pre...use-/321134976039?pt=Mice&hash=item4ac522dc27

resolve that problem.

3) TWO (2) tablets in your car?!? This is simply badass! Please post pics of setup (including license plate and gps coordinates) I will rob you blind :) JK JK JK but seriously ... if the mini is to be permanently mounted on dashboard during the day time... I'd consider a reflective cover or at least an IR/UV resistive/reflective film on the windshield above it? Hopefully WHITE mini... that sun can do some serious damage I'd imagine. That mini is going to get HOT with wifi and screen on full all the time.

***the easiest solution to this is either use a windows XP tablet or a pico projector connected via mhl / hdmi to your double din tablet.***

pico can bounce off a small mirror and then windshield so orientation will be correct natively.*******
[General Questions and Answers] mcdull:
bluetooth mouse is not as good as original pad and even more difficult if the image is not clearly projected.

2 tablet in car, the android nexus 7 should be fixed in car and the ipad mini should be portable and carried with me.

So you just need to start an app and establish connection and place it under windshield and the projection is ready.

When you off the car just pick the mini and go with you.

Why in God's name would you want to carry an ipad when you could carry nexus 7? :)
[General Questions and Answers] cbroughton:
Old post I know but I'm fairly new to Android. Anyway here's my idea building on the VNC option.

1) HDMI out of your Android to an HDMI screen like a 7" Liliput field monitor.

2) Either find a screen that gives you the option of flipping the display (the Liliput only seems to flip analog video) or take apart the screen and physically flip the lcd panel and place it back over the backlight.

Didn't say it'd be easy or cheap but I think HDMI out is the way to go if no root software solution is possible. Control does seem like an issue although Google Now's voice commands are getting pretty good.
[General Questions and Answers] willfck4beer:
Good news bro!

If you are willing to physically flip the LCD panel ... you don't even need VNC involvement at all.

That's a great EFF'ing idea - certainly out of the box but hell yeah! Provided that the housing can accomodate the flipped LCD portion and there are no polarizer issues and no localized LED brightness (this would be reversed).

Simple. HDMI out to the flipped screen and it should work just fine.

That's odd that the liliput only flips analog. Every projector and pico I've ever tried has this option IIRC for all inputs, digi too.

That would seem to be the easiest solution, just find a fieldmonitor that has digital flipping/mirroring.

Alternatively, if we could isolate the HDMI out signal and DSP it to be mirrored that would work too I think.

<vent> Odd isn't it that we can't software flip in an OPEN SOURCE OS. What was the point again, why not MS or Apple? </vent>

Don't ever apologize if you are putting forth suggestions to someone else's problem. You rock. All input is always appreciated. Thank you.

[General Questions and Answers] 1454:
Thats cool man. I eagerly await the addition of navigation. Btw, off topic question, you have I radar integration so I assume this means you have one? If so, is it worth the money?
[General Questions and Answers] jhanson:
Yes, I have the cobra iradar irad-100, and I really like it. It's better than a standard radar detector IMO because of the online database. When it's connected to your phone, it is constantly taking your gps location and checking against user reports for last known locations of radar traps. If you get a radar hit it asks you to verify if it is a real trap and if so, it reports it up to their database. I don't really speed, but its still a nice thing to have. I got lucky and found it on a deal site for about 60 bucks and have been very happy with it.
[General Questions and Answers] willfck4beer:
I bought the iphone iradar on accident... I am lying. I actually bought it knowingly... but it was on sale at Radioshack for like $30 compared to android $80ish.... I figured we'd be able to get it to work (quite naively I guess if we still can't even rotate a screen on an open source os)... have you guys had any luck with the Iphone version?

On a side note; I just used an obd2 to bluetooth gateway to have my note2 talk to ECU with Torque app; and I used the torque liveview plugin (in HUD mode) to mount the liveview on the dash and have a cluster of gauges in HUD. SICK!
[General Questions and Answers] Fat Albert:
It's been done commercially, at least for Froyo

The Seeser is an Android Pico projector using a laser to generate the image, download the user manual from espluskorea dot com, customer, manual & download and search for mirror to see the function

I'm intending to use one to wirelessly replicate (using MirrorOp) the screen of my flight navigation software (XcSoar) as a head up display on the canopy. The main advantage of laser projection is obviating the necessity for focusing the image, even on curved surfaces. The big issue will be image brightness, it's just about impossible to find a more hostile environment given the ambient light level several thousand feet above the ground amongst fair weather cumulus...
[General Questions and Answers] willfck4beer:
DUDE!!! Good find!!! Thanks!!!! That's soooo cool!!!

Can you upload kernel somewhere?

I'd imagine this would need to be in kernel right? Or am I totally offbase?

Could the portion of code that does this be copied from Fro Yo to KK?

I'll definitely set up some alerts for when they release source for FY and KK.

Anyone have any more input on this? (and/or a way to do it under windows x86?)

I'm so envious of your laser... been so annoying constantly adjusting my optoma pk201. It's hardware rotate was almost enough to get me to install it in the car. I've been investigating thin film fresnel lenses too.

Thanks again for the info!

[General Questions and Answers] keliuss:
Wow! This thread is ongoing since 2010. I've just tried out one of the many speedo HUD apps on the play store and thought it was great, but would love to be able to do what the OP [MENTION=611699]Phexi[/MENTION] asked for; mirror/invert/flip/reverse the display (any app) to use as a HUD. This way we could use it for navigation. There are navi apps that offer this now but they are few and have limited options.

Some 2014 searching on the play store reveals some HUD apps but nothing like OP asked about.

I would love to see a simple app/toggle to invert the display. Can't believe nobody (devs) has done it yet.

Navier does it well enough as a stop-gap. The problem with Navier is it uses cell network for map data, not good if you have a data limit, or outside of network coverage.

I mostly want to mirror my texting apps. Wha? Texting while driving is dangerous, right? Well, what if you don't have to take your eyes off the road to read them? With a bluetooth headset you can even reply...then again, I'm betting you could just use voice commands to activate all that somehow.

I can't believe this thread has been going for FOUR YEARS and nobody has come up with a way to simply flip the screeen.

If you google your favorite sat nav app with 'hud mode' in the search term then you will find a addon or hack has been written for it. For example iGo has one and I believe Google Maps has a few.
[General Questions and Answers] ctzn1:
even though android is open source, allowing modifications to be made to what us displayed is a huge security risk so they probably locked it down.

If we are able to flip the x-axis coörds then any hacker can mitm your mobile banking apps.

Https an ssl encryption won't protect you against that.

But i also want to be able to mirror over the X axis.

I searched for xposed modules and kernels that can do this but i found none.

when i get to my laptop i will investigate the possibility of making an app that does this.
[General Questions and Answers] sosodemi:
+1 looking forward to see this happen "display flipping"

Than it would be possible to use any navigation app with the display projection on the windscreen.

If it (the hud apk) would be gyroscope sensitive than, when the user would pick up the phone of the dashboard, the screen would offer a possibility tof turn it on/off.
[General Questions and Answers] ctzn1:
I don't think that that gyroscope thing will work, if you drive over a curved bridge then your screen will turn off.

Guys, its only a small step away for cyanogen mod users (at least for some).

I am running "Native SBS" for Android:

https://plus.google.com/u/0/communities/117807409036006925326

This little app takes the screen contents and doubles it.

While this is not what you guys look for it still does 99% of the trick: It can take the screem and process it in realtime.

Source code is there (i built the apk myself).

Its just a few lines of code to make it mirror the screen instead of scaling it down and doubling it.

Of course if you browse the comments it only works on Cyanogen Mod phones and only some of those.

It runs fine & fast on my Oneplus One.

Greetings,

Ender

P.S. key is if the developer releases the code of his "workhorse" lib surfaceflinnger or if he is willing to modify it.

HUDWAY

done.
[General Questions and Answers] DanLynch:
Yeah, done other than the fact that Hudway doesn't even vaguely address the screen flipping issue which is the only part of this discussion that hasn't already been solved 12 ways.

Nobody cares about one more app with a screen flip mode for that app and nobody needs one more example of a screen film or a plastic reflector. I can link a dozen examples for each of those. Most of the people on this thread want to flip the entire screen so you can use whatever nav app you want.

[General Questions and Answers] working man:
Another one that would pay for that right here!
[General Questions and Answers] fleamage:
Agree.

We are not looking for a simple application that can mirror some glyphs or static images. We are looking for an application or mod (Xposed, maybe) that can mirror the android screen itself.

If somebody can develop it and put that on google play or some other purchasable place, I would buy it for sure... (I think $10 for a license is a fair price)

That way, you could use Waze, Sygic (full interface), some simple text applications or even minimalistic texts, tasker and many other useful things that can turn your night drive experience even better.

My guess is that this is something kernel related, I think this is not achievable by the OS level. I can develop very simple android apps, but I never messed around with kernels, I don't even know where to start.

Hi,

would be great if i put my tablet under the windshild and this all mirroring to me as driver,

because, i can look on the windshild and can controling my Galaxy 10.1 over my windschild..

and can selecting all apps what i want, include OSMAnd~, speedometer and others.. and all

it is reflecting-wrong on the tablet direct but become on the windshild the right mirrored reflected :)

this is the sense behind . for using tablets to have an head up display..

and in front maybe a dark foil for it.

We are need only a HUD-App for tablets and handy's ;)

Tis one always gets me crazy searching. .no, digging!!always tot its a gud idea.. i put ted on while i drive and hud it backwards .but just a tiny bit coz place at end and out of the way enough just to grasp a a rough image of wats going on in the video..as forr navi, most hud mode navi ive tried.. none gives the same exp like when using something like waze or maps.. i guess the safety thingy is cocblock them to dev a ful disply hud version.. and mayb the the brightness issue, but im suprised with all the motion and glasses fad going around they cpuldnt find a compromise.still gptta settle for phonr+mirror-windshield if wanna get the full flip.. i place it in a position backwards enough to hav thr screen project only on the top tintsun blocker thingy so i can hear evrything n only can see some of it .. like catching something at the corner of ur eye but cant really tell.. onlu until i look up i can realy view.. but i guedd if the tints too heavy it defeats the purpose of hud.. so i tried far right drivers side .. at the front . I realised its still ok.. doesnt affect much sight.. but i think ive come to the conclusion if its ever gonna be effective is had to be able to shift possitions at an instant and include other controls to aid like motion , voice etc. And i think i only put atention towards the display when the car is more idle.. so im thinkin how bout calls,reminders ,those typr function can be left on, and only when speed decrease to a ceratin level tje full function will be unlocked.. sprta like the treadmills at the gym.. itll stop webbrwsing,youtubing if runing speed is below 40 i think.. ill keep thinkin..

Sorry 4 d messsy writing. Well.. just had to get something out after hours trying dif keywords, came out same..

Ill keep learning n thinking.. hope some gud wil come out of all this.. cheers

Wow, now here we are in 2016 and still nobody had figured this one out yet !!! How hard can it be? I've searched for days now and can find nothing ANYWHERE ? I just drove 7 hours from San Francisco and used a hud speedo while my wife watched movies on her note tablet. And so I thought hmmmmm ?↩↪? Of course I wouldn't want my eyes to be distracted from the road while driving and watching porn on my windshield ! But just other useful hud of screen would be useful, btw could other drivers or passengers of other vehicles see my hud ? I mean just in case of privacy issues you know like banking or shipping on amazon or watching porn. Are there laws against hud in vehicles? What about using a fresnel (sp) lens? Or 2 ,one reversed? Or how about a simple app with screen orientation control flip flap and floor ? No? I will I await answers until then I well just continue practicing my mental flip image skills by standing in front of a mirror and using my android phone, I've almost got it down but when walking I tend to bump into things because I turn the wrong way! So now I stay clear of sidewalks and cliff edges.

We can buy and fly drones fpv smaller than a matchbook that cost less than a $100, but we can't flip our phone screens??? I guess I'll just have to go for a fresher lens and full windshield reflective film, you know for that BIG SCREEN effect. Lmao.

reversing Fresnel wide angle lens 8 x 10' on ebay for 7 bux.. Flip it over should magnify and still reverse left to right.... rotate 90 degrees and presto instant hud mode. You'll need a reflecting sheet behind it. alternatively, cut out a much smaller piece of the lens and stand it on edge in the light path from phone to windshield... this lens is like a thick sheet of plastic so no shrapnel.

probably best would be to leave the phone on the dash close to thee windshield and hang the lens vertically in the light path from reflection to your eyes

[General Questions and Answers] mcdull:
It cannot be an app. App development is simply impossible to implement this feature unless you are going to simulate the entire android system on an app. If it has to be done, would temper the hardware abstract layer HAL and is device specific. It seems possible to implement this in a specific device using a specific custom kernel but won't make it generally usable.

Another possible solution is an app that mirror and flip the screen of another pad. E.g., you have a nexus7 put on the stereo din and broadcasting screen to an 5.5 inch phone (e.g.nexus 6) putting under the win shield. The nexus 6 would only act a screen of hud. Operation had to be done on nexus 7 which is not flipped. That would be a lot easier and practical.

[General Questions and Answers] nijohnson:
so here's my thinking. You don't need to reverse the entire display. just one app at a time. how would this work?

there are apps like "floating apps" which esentially widgitize an app

there are apps like "mirror reversal" which flip an image.

is it possible to take code from the latter & insert it into the former?

Oh. Sorry. I just read the previous couple of posts. Sounds like my idea is infeasasle
[General Questions and Answers] braxxx79:
Until the app is developed. Simple DIY fix

Just place a small mirror flat under the windsheild where you would normally place your phone. Just in front of that mount one of those angled clear acrylic buisness card or photo holders from office supply store. Then when you place your phone (facing away from you) against it the image will get corrected before displaying on windsheild. If the acrylic isnt quite the right angle just use a lighter to heat it just enough to bend to the desired angle and it will harden again when cool. Someone may have already suggested this. I dont feel like reading back that far.

Here's a thought guys, why can't we setup the Android with something like a VNC server and VNC client and connect to itself with the VNC and have it rotate or mirror the screen. Then once you connect you hit the button to show all your open apps (in a mirrored POV) then once it's open you set it on the dashboard and there's a HUD reflected with the correct mirror.
