[Q] App that mirrors the screen to use it as a HUD

Thread starter Phexi
Start date Sep 9, 2010

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...

I am working on a solution that allows you to get a readable reflection of the phone on the windshield. You can use a special film on the windshield (50% reflective - 50% see through) to improve the quality of the image (eliminate ghost image). I have made a working prototype, the solution is simple, compact and doesn't require one to hack the phone. Using it in HUD mode works great at night and also on a cloudy or overcast day but it doesn't work on sunny conditions. On a sunny day one would use it as a regular phone mount on the dashboard. Is there real interest from this community for such a product?

like this... its ready out there https://www.amazon.com/Techstick-Di...8&qid=1495733011&sr=1-24&keywords=hud+display

The film that goes on the windshield is like the one in the link. The one I am using is made of different material so it doesn't leave bubbles when you try to install it. The big difference is not in the film, it is in the fact that the image reflected off the windshield is the exact image you would see on the phone screen. No need for HUD apps, you can use Google Maps, Waze, Uber, Lyft or any app on the phone.

o that is great i would be very interested in buying it

That's great. I'll send you a message and keep you posted as I make progress.

#147

Found this today:
I think it will do the job.

#149

Yes, I know. I've posted just in case anyone is interested. I also want a software solution and not an expensive hardware. But from the video (including iOS') we have an idea that it's possible.

#150

Sygic is the best but you have to buy the HUD as an extra though

#151

Vision HUD

The android app you require is Vision HUD. It is designed for use with the HUD or just your window screen.

Phexi was not looking for an app that has HUD mode, there are lots of apps designed to work in HUD mode including your suggestion. The tread is about finding an app that would reverse the display of other apps or the entire device screen. It looks likely that this would require a modified kernel though so thanks for the suggestion.

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.
This doesn't seem to hard to me however sitting here 10 beers deep wanting it for Waze on my droid as a HUD on the truck windshield in a friends truck isn't the time to do anything more than throw this idea out. I love a challenge! Someone tell me I'm right or at least onto something that could work without development.

Hey sumerboard, you are probably nearest to a possible, sort-of solution, have another beer for your thoughts

VNC displays an image of what is on the screen already so I think this would require two devices, plus some programming. I agree with mcdull in below about the android system and that a full solution would require a modified kernel on a rooted device so this suggestion is a combination of what you suggest and what mcdull suggests in his post #114t:-

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.

Now I know that what he suggests, an app that mirror and flip the screen, is essentially what we are looking for already except that he mentions two devices.

..So if you had the server device running any required app and mounted normally in the car (or truck in your case) with a VNC server running in the background, that device could be linked to a client device running a modified version of a VNC client which mirrors the screen before displaying it - that should work as long as the updates didn't need to be ultra fast - and providing you have access to a spare device for the HUD. The devices would also need to be linked together through wi-fi or bluetooth.
Yes I know that involves editing the VNC client source but the extra overhead to flip the screen would be on the client side and the primary device could get on with the main job of producing the display. No, I doubt I will get around to looking at the VNC client source to do that but this is xda forums.. must be someone here up for that challenge?

#153

Woo. It has been an really old post. The beauty of having the client server approach is that you really need the primary device that you can interact with to be mounted on the dash board. Or even there are tech to flip and invert the screen, you will need to remove the HUD from wind shield, set it to normal display and operate the UI and activate the HUD mode and put it back. Which is not acceptable during driving of course.

As most ppl interested in this topic has already mounted an android in the 2DIN spaces of the car audio, there will be least effort to add a dump device (preferably OLED) just to mirror and flip the screen. All operation is done on the primary device nice and easy.

Hi! This app work fine for me at the moment, waiting for google's full screen mirror option instead!

Name : HUDdle - Head Up Display
Link : https :// play.google . com/store/apps/details?id=co.aquaapps.huddle

Fully personalizzable interface for display the data that you need!

Hi. Don't know if this has been suggested before.. I have been waiting for a way to mirror the screen for hud display of ANY app for years now.... what if you used two reflective serfaces? So have the phone facing down at a 45 degree angle and letting the screen reflect off a mirrored surface sitting flat on the dash then reflected again off the windscreen. Wouldn't the light being reflected twice make it appear normal? Ok so it's not pretty but surely easier than having a whole other device to stream a vnc from. Thoughts?

#156

I know this is an old thead, but I'm still looking for an app like this and can't seem to find it anywhere. Any new information?

I know this is an old thread, but I'm still looking for an app like this and can't seem to find it anywhere. Any new information?

I have been working on an optics/mount solution that will achieve this. I attach a photo that I took at night:

For this photo I was using Google Maps, but this would work with any app such as Waze, Uber, Lyft, Android Auto etc. A few other things that might not be evident:

1. The virtual image (reflection) appears to be floating 1m or more in front of the windshield. In the photo the virtual image is focused closer to the white wall. With the current mode of reflecting the phone directly on the windshield the reflection is at the windshield, so the driver's has to refocus close.
2. The double reflection is "virtually" eliminated. It is never actually eliminated but the second reflection becomes more aligned with the first reflection. This will depend on the car, as each car has slightly different windshield.
3. No special wedge windshield or reflective film is required.

So this solution does more than what a software fix would do. Also during the day the "gadget" could be used as a regular mount.

I can't give away the secret but I wanted to gauge if there is any interest in such a gadget.

#159

Finally did it!!

I know im late. But thanks to this thread. After reading all these posts, i was convinced that there are no existing mods, or any other ready made solution available.
So thought of doing it myself. Changed the source and built a custom ROM on top of lineageOS. Added a new option (HUD Mode :cool: )
Here is a working video of my HUD display. cheers.
