I have RCA connections in my CAR touch screen panel and can view the screen from galaxy s i9000. But is there a way by which i can transmit the input from my touch screen Car nav panel to android phone?
I think is not possible, there are people working on otg usb but i don't know if will work for that
but, i think it's possible.
cause i connected a Bluetooth mouse and working perfectly.

I have one of those Android HDMI TV sticks (A variant of CX-01, to be exact.) running 4.0.4, successfully rooted and hacked up to my liking. There is one thing I would like it to do, which, in my case, is the reason to own it in the first place: I need a very portable presentation device, which I could plug into anything with a HDMI socket and play a presentation. (As a side note, it boots whenever it gets power supplied, so you can use it as a very hidden cheap web server - it's smaller than a Raspberry Pi.)
There is a problem with this usage, however. The device comes with a 2.4 GHz wireless accelerometer-based mouse with a few buttons, which is it's only input device, connected over USB OTG. (Replacing it with something else would be very much not cost-effective) That mouse is only usable because when it is connected, ICS displays a mouse pointer on screen, otherwise, navigation would be way too cumbersome. I have replaced the stock mouse pointer with a smaller one by replacing the png image in framework-res.apk, and it's good enough. Using Hide Bar, I was able to hide the status bar (the wireless mouse has back and home buttons) so I get the full screen for my presentation.
During the presentation itself, I need an input device to move between individual slides and otherwise trigger execution, buttons on the wireless mouse work, or can be reassigned in various ways. However, I need the mouse pointer to invisible during that, as the motion sensitive wireless mouse would make it move constantly while I'm talking with the mouse in my hand.
There is apparently no way to temporarily disable the accelerometer in the mouse itself, while it has a power button that disables it entirely, it turns off everything, including the buttons, and pressing the buttons enables the mouse again.
This means I need a software means to temporarily hide or disable the mouse pointer. (I can obviously permanently hide it by replacing the pointer with a transparent PNG. That would make it very hard to control the device, because the only button it has to trigger a control actually simulates a left click, so it's out.) Extensive googling failed to provide an answer -- most of the time people who get a mouse pointer they don't want seem to eventually give up and pick a HID device which does not produce it instead. As far as I can see, there can only be two ways to do it:
Somehow get the OS to think it has no mouse HID device, or that it's not moving.
Somehow force the mouse pointer to stick to a corner of the screen and keep it there while it's not needed.
Unfortunately I could find no clear sources on either method. I'm not above some hacking and programming to get it done, but I would appreciate an advice on what to look for.
I've purchased this keyborard from Amazon and it paired flawlessly. It's funny to see the tiny pointer running acros the screen.
-
The media keys don't do the required functions for android, but all the other normal keys do well. The touchpad is excesively small (as for my fingers....) for the dimensions of the keyboard but do its work altough sometimes the pointer freezes if the click is repeated quickly.
-
It sleeps if not in use, and awakes if I pulse the mouse buttons.
-
It has the dimensions of a full keyboard without the numerical pad, replaced by the touch surface, ideal for use the kindle connected by HDMI to the wall TV....
I'm surprised to learn that we must keep our eyes on the tablet while clumsily tapping even when the tablet is connected to a big display.
Instead of plugging a mouse into the touchpad (I guess that's the current workaround), why not turn the tablet into a touchpad when mirroring the display of the tablet on a large screen? With that setup, the tablet display wouldn't actually be mirrored, the big display would look like a desktop computer display with a pointer floating around on it. Also, the virtual touchpad on the tablet could be resizable so that you could simultaneously show a virtual keyboard (neither of which would show on the big display). Or there could be a spot on the tablet display tapped to switch between virtual keyboard and touchpad. Again, neither showing up on the big display.
Let me know if I'm not being clear enough. This has nothing to do with simply mirroring the tablet display to a monitor/TV, I know that can be done through MHL and HDMI stuff. Also, it has nothing to do with using the tablet as a touchpad for another computer. The only components are the tablet and the big display (monitor or TV).
And of course if it's already been done, please let me know.
The simplest of implementations...
The big display would mirror the tablet display. The tablet would show a tiny pointer. How small doesn't matter because you won't be looking at the tablet. The pointer location would correspond to the current pointer location as shown by "developer options" on anAndroid. That pointer would be driven by touch. That should be easy enough, the only difference is that a relative pointer position would be used instead of current finger point position.
Apparently 99% of the programming for this stuff is already done on Android tablets. Probably also on iPads or whatever. It would just need a GUI switch and to make a few tiny adjustments when connected to a monitor.

Anybody connect their tablet to a large monitor? Enjoy fumbling around on the tablet when you could be using precise pointer control? Think this might help for stuff like browsing?
Anybody?
i bought a
2GHZ Double Din Multi-Touch Capacitive Android 4.1 GPS Nav Car Stereo DVD Player
it wont lt me link to the item but if you go to ebay and type item number:261318867404

Hey guys, do you know that you can attach Computer's keyboard and mouse on your broken touch panel phone if your phone supports OTG.
And till the replacement of demaged touch display panel you can still use your phone.
