Hi,
If you have a Android tablet/device with Resistive Touch screen and HDMI out, you can probably connect an external LCD screen with Touch panel to it.
Based on- / inspired by- the Martin Drashkov experiment (martin.drashkov.com/2011/09/android-megapad-23-android-tablet-for.html) I tried a mod with a 23 inch Resistive touch Panel (and external LCD screen) on an Android Tablet with Resistive Touch screen and succeeded.
The Resistive screen tablets use - in most cases - 4 wire Resistive Touch panels.
These panels are "interchangeable". The 23 inch Resistive touch panel I used for my proof of concept worked absolutely fine and without the need to adjust settings on touch positions.
See my blog post about it:
beyondthekeeboard.wordpress.com/2011/10/05/bigscreen-android-with-touch/
If anyone is doing similar experiments, please share.
It is fun to know what else is going on.
Different approach
I`m digging your post out, since I´m just about to evaluate a different approach on adding a larger, external TS.
Since recent Android revisions have full support for USB host mode, it should be possible to use a large Multitouch-Monitor as output device (MHL to HDMI). The Touchscreen (Acer T231Hbmid MultiTouch) has an USB-Output for parsing the HID, which (I hope) should work with my SGS3.
I will post the results after testing this setup on weekend.

Hello, look your messages please)
Seriously would love to know if this worked.
I am thinking of getting a Android on a stick for use in a 23" touch panel exterior monitor for use as an interactive display at a trade show.
Wondering if this concept will work.
I have an Acer T231Hbmid MultiTouch and a MK802II Rikomagic device. I try, but i don´t get it to work. If you have any idea, tell me, i will test it.
Acer T231Hbmid + MK802II works (USB connected). Search for "Acer T231Hbmid + MK802II" at youtube.com (its a bit laggy). Just get the right driver compiled and insmod them with a terminal.
Here are some links that seem relevant. I have been wanting to try a similar thing over bluetooth (which is proving to be difficult so far). I am going to take a step back and try usb first now.

The Asus Transformer seems to use an input device configuration(idc) file, as I had my friend take a look and indeed there existed more than on my GS3. I think it is for the touchpad equipped keyboard.
I've been trying to do this for a while with my Dell 22" touch screen and my Motorola Xoom and it finally worked by using a USB OTG adapter from Amazon for about £1.50. Winner.
The only problem I have is having to use a keyboard to go home as the bar at the bottom of the screen is not displayed to touch. Is there a work around to this?
you guys are awesome!
There is definitely a market for this. A lot of people I know would love to have a larger touch display that can be set up in a car that can be used to control music, maps, and that plays movies while connected to an android phone.
I say you guys should put these ideas together and work on getting patents before someone exploits the market.
If you hold patents, other people with more time and resources can further developed the concepts, while you still get a piece of the pie.
Brilliant!
Hi there.
Is there a small screen for this?

Another company looks like they have something similar to the MimicsX2 thing called "Smartphone Uplink SPU700". I am trying to find someone who has used it (or both would be excellent for an actual review/comparison ) before I buy one...
Woow interesting subject! :good:
I was wondering is there any possibility to do this with a nexus 5? My point is: can I make myself an external touch screen using the phone's slimport to hdmi capability to use it like an asus padfone or so (without additional battery)?
I would like to control my Samsung Galaxy S3 (MHL compatible) via a MHL 3.0 cable and this touchscreen. Any ideas/advice?

stackoverflow.com
I have been searching but sites don't give much details.
My friend has a A500 and another has an Asus and they both have poor touch sensors, when selecting a word when typing it chooses the 4th word instead of the 3rd for example.
So I am looking for an Android tablet with a good sensor.
Dont care to wait for a Tegra 3.
My requirements in order of importance:
Very good touch sensor.
Needs HDMI out and 2 USB. for keyboard, mouse/controller and TV out.
10" screen.
Available to have Android updates either through being Rooted or not if possible.
Headphone out.
non-pentile screen.
things I dont care about:
Hardware keyboard
Software UI mods and additional apps
Camera
Sim card
removable SD card
overall size and weight
I think the word selection is a problem on most honeycomb tablets. I myself have a transformer and i mean maybe once every few weeks the touch sensor doesn't work but you just turn the screen on and off and it's fixed. The TF/Prim has hdmi and and you get USB with the keyboard dock. I would highly suggest you wait and pick up a Prime assuming they didn't go the route as later transformers and lock them down. But anywho Asus has proven they are good on updates

I had this on my Nexus One, it drove me crazy for a long time always having to turn the screen off constantly when using it at certain angles, sounds like a hardware problem, I wouldnt be surprised if Asus and Acer get their touch sensors from the same company.
Well with me it's a "ohh it will only take 10 seconds" really it doesn't take that long
I don't like any of the tabs out right now that most can buy, I would say the 10.1 seems like the best. I think the 8.9 could be better, but I have not tryed it yet. I would wait for the prime if you can.
i recommend these two to u, my brother decides to buy a tablet, too. These two are his results of searching. He will buy either of them. so posting here and offers u more options. : )

also IPS screen, and the ability of game-playing is stronger than the former tablet.
as far as i'm concerned, i suggest u not to wait for tegra3, it must be very expensive.

Moved to proper section, please read the rules before posting.
I would like to get some opinion from you guys....
I am a startup developing a new kind of mobile device that combines a phone and tablet - putting a 7" screen on a less than 5" phone body. (It is not like the Galaxy Note, where the size is fixed.)
SO when you just want to make calls, check SMS and emails, just use the "phone mode" with a 4"+ screen.
When you want to surf web, watch videos/photos, transform it into a 7"-screen tablet.
Now my question is about the potential market for this device, as it seems that no company is creating a device like this, I am worried if there's no market for it.
a) For those of you carrying two devices (a phone and a tablet), are you feeling a bit inconvenient, annd would you like to have this device?
b) For those of you carrying only a phone, would you like to have a bigger screen, perhaps 7", while retaining the same portability?
c) Would you still buy a 10" tablet after you have this device? (assuming you already have a laptop)
Your help will be very much appreciated!
the first thing that came to mind upon reading this post is the asus padfone.
i do carry the 2 devices (S2 + TF101), and IMO it isn't really a big inconvenience, thus i might not be that interested. Unless it comes with a unique feature / selling point?
cheers.
if the tablet could make calls and i could pair a Bluetooth headset to it, i would get it. maybe it would stop me from texting and driving if it was 10 inch
I see no market for it. Some will buy it for what it is but not enough to make profit or even break even. Try focussing resources on let's say the body of the Droid Razr with an edge to edge screen, custom ROM that gets rid of the touch buttons of the bottom of the device so that can be more room for screen. I would buy something like that.
Or how about a smart-watch that can sync with any tablet to become a secondary display.

Thanks for your reply.
There are some aspects of Padfone that we don't think it will be a market success:
1. You still need to carry the 10" screen, and it is not as portable as a 4+" phone 2. When the phone is inside tablet, you'll need a headset to receive and make calls
Anyway our product is not in compete with padfone, although we have something in common - to combine devices from different categories. The key difference, besides the size, is that we emphasize on PORTABILITY; while they probably emphasize on versatile performance.
Our device is small and light and easily slip into pocket, yet comes with a beautiful 7" screen.
BTW, we think the combination of devices (our device + laptop/ultrabook) is more reasonable than (Padfone + laptop/ultrabook), because Padfone size is already very similar to laptop, and almost everyone already has a laptop.

Do you mean Sony's Tablet P?
However, since there is a bezel between the two screens, it cannot be seen as a one screen tablet when unfolded. In fact this is one of the main reason why it gets poor reviews and market reactions (http://www.bloomberg.com/news/2012-03-21/what-was-sony-thinking-with-tablet-p-rich-jaroslovsky.html). The bezel is simply annoying.
Our startup have found a way to remove the bezel.
Yes people now used to carry around many gadgets, because currently we have no choice
I love the idea of the padfone...4 inch phone during the day, 10 inch phone when at home.
If you have something to offer please let me know, as of know i am seriously looking at the padfone to be my next phone.

Tablet s Phone
I really dont understand why Tablets dont incorporate phones, I own a Dell Streak Mini 5, (best phone Ive ever owned) also a sony tablet s.
Both brilliant devices but most of the pros are duplicated by one or the other,
Dell streak, android device, good general purpose but screen too small for word processing or watching vids, not to mention the small onscreen keybord.
Tablet s, android device, good for all things android but no phone.
I dont follow the logic that there would be no market for a tablet device with a phone, I carry a phone and I carry a tablet I would far rather only carry one, i.e. the tablet with a phone in it, I use a blue tooth earpiece for all my phone/music/audio books so its not as if Ive got it stuck to my ear all the time, in fact the phone never comes out unless i want to use an app.
So the answer for me is a resounding YES device of that nature.
This is a great idea. Today's smartphones have all this horsepower but what good is it if the tiny screens make it a chore to get anything done. I'm having difficulty imagining how one would go about incorporating an additional big screen on a phone, but if you can do a clean job at it, I believe it will be success. By clean, I mean the screens should be good quality either glass or matte, not some flimsy folding ****.

Yes we are not using folding screens.
I bought a Samsung Galaxy Note exactly for this reason.
The screen is big enough for non-phone usage but small
enough to fit inside a pocket to carry around like you would
carry around a phone. It's already 5.4" so 7" is not that much
larger, you'd better have a real compelling reason for your
device in order to convince people who would otherwise
pick the Note.
Cool Idea
I don't know of your resource base, but have you seen the new translucent material they have demoed for new tablets. That would make your product something that would stand apart. They demoed the material at one of the electronic shows this year.

I could not find that this question has been asked, sorry if it has.
I was wondering if there could be a way for the galaxy note 10.1 to function as a standard wacom tablet for use on a computer through USB or something, like a bamboo or intuos tablet. Possibly even like a cintiq using remote desktop and photoshop?
Just wondering, thanks

I was also thinking if pressure sensitivity would work through RDP/VNC - that would allow using desktop paiting apps on tablet (although with some limitation - RDP/VNC mostly has less colors and some lag).

That's what I was thinking of. I know the remote desktop clients are a little laggy on tablets and maybe not ideal, but at the very least it would be fun to paint with the Note on my PC. I don't know how small the market is for using this tablet like a wacom pad, and the note 10.1 is kind of niche on it's own, but for people like me who draw casually and don't want to drop more cash on a wacom it's ideal.

As a USB-conncected input peripheral - probably not. "Penabled" digitizers such as the one in the SGN10.1 use a different set of software drivers than the Intuos and Bamboo non-display digitizers. This is because the underlying hardware is different; Penabled styli cannot be used interchangeably with Intuos/Bamboo styli, although many of the nibs (regular, felt, stroke) can fit either type of stylus. Technically it may be possible, but Wacom probably wants to maintain a clear distinction between its' product lines.
With remote desktop software - yes, but there may be mismatches of screen resolution which would complicate fine-line drawing control, and pressure response would be lost. And added lag due to the remote connection.
Best to get a Bamboo or Intuos if you really need a graphics tablet for a desktop/laptop - the software drivers allow scaling the digitizer area to single and multiple displays; more levels of pressure response; and stylus tilt response and touchpad controls are available on the Intuos series. (But not cheap - the Intuos 6x8 runs about $350.)
Search for a cheaper intuous 2, 3 or 4 used. They are good tablets, the new ones are not that different in functionality, just thinner (the 4 is just as thin as the 5) as an added bonus you gain pen rotation and the eraser on the other side of the pen (which I use but not everybody does).
If you really want something smaller and don't care about the rotation of the pen then get a bamboo (as usual if you want slightly cheaper get a used older model).

Yes, good advice - my Intuos2 from 2002 is still good. Doesn't have the touchpad controls of the current Intuos5, but works fine. Wacom driver updates still include the Intuos2, from WinXP to Win7, and probably beyond. Styli, nibs, and most accessories are still available for the Intuos2 as well.

Getting a Galaxy Note at the end of the week, this is the first thing that crossed my mind, if it could double as a Cintiq. My best guess is that its possible, specially considering the power inside the tablet, and maybe a usb 3.0 connection -____- Still haven't seen any sofware up to it though. I would gladly pay for any software that enabled this. Otherwise, I guess Sketchbook Pro for Android will do, I have used it with a capacitive stylus (ugh) and it did ok, can't wait to get Wacom superpowers on the go =) I also own an old HP PC tablet with an active digitizer, but its to heavy lo lug around daily, and a wacom bamboo for my PC tower, so I have high expectations on this. I just cannot wait to put my hands on the Note.
BTW for the phone Note, there is this, dunno if it works on the tablet:

The reasons Galaxy Note 10.1 has potential to become drawing tablet are... 1,024 pressure sensitivity(about 4 times higher than Note) and it's big enough to actually draw on it.
I will buy any app that transform Galaxy Note 10.1 to Wacom Especially if it works with Ubuntu.
Hi Everyone,
I registered on xda-developers just to post on this thread. I'm getting into Android app development, and I will be getting a Galaxy Note 10.1 in a few days. Like many others, one of the first ideas that came to mind after playing around with the Note was finding a way to use it as a writing tablet (WACOM style) for PC. I do a lot of tutoring and having an affordable way to provide a screencast of what I'm drawing to students when working out a problem or teaching would be very useful for me.
I'm planning on writing a simple app to let Note users control their PCs with the S Pen. From there, using some PC based software to transmit a screencast over skype for example should be straightforward. I think the most difficult part will be getting pressure sensitivity information to the PC and into applications, since usual ways of emulating input are just to control the mouse pointer position, and button and keypresses.
I'm not sure how long it'll take, but it's nice to know that there are other people out there who would be interested in this kind of functionality.

Wow, it You succeed You would be a lotta people's heroe including me :laugh:
As I wrote in my OP on this issue the way to a full functional Wacom dig tab function of Note 10.1 could be managed like THIS:
Basic prerequisites:
Note 10.1's digitizer FACTUALLY IS a WaCom digitizer ! I have the Bamboo digitizer connected to my PC via the wireless USB dongle.
Step one:
Download "Bamboo" drivers to PC
Step two:
Write a WiFi and Bluetooth connection interface for Note 10.1 to transmit digitizer info from Note 10.1 to the installed PC drivers via WiFi or Bluetooth
Step three:
Create an app for Note 10.1 that resembles the physical surface of the Bamboo dig tab including multi-touch input (e.g. two-three and four finger swipe functionality) and the four hardware buttons.

It would be a miracle if I do, I think lol
I agree with your idea of how to go about building this, except that I think using the current Bamboo drivers might not be so easy. The drivers will be expecting a real Bamboo tablet to be connected to the computer over USB (direct or wireless dongle) and will communicate with it directly. To be able to use the original Bamboo drivers, we'd have to reverse engineer the communication between a real Bamboo tablet and the drivers, and then somehow write a new device driver that pretends to be a USB device, and then communicates on one side with the Note (not impossible) but on the other side pretends to be a real Bamboo tablet to communicate with the real Bamboo drivers, the same way a real Bamboo tablet does.
What I'm thinking (still have to look into it) is that Wacom probably published some kind of documentation for how third party apps can use the tablet input including pressure sensitivity. This will tell us how for example Photoshop retrieves pressure sensitivity input.
Maybe this project won't be very simple after all.

I looked at that link, it looks like the software part of the development kit isn't available online, only by email if you buy the hardware development kit.
I did a bunch more research and talked to an engineer at Wacom USA, and I think I have a fairly good picture of how this whole thing works.
Essentially, Wacom tablets are USB devices. There are two ways a digitizer tablet can get its information into an application.
1/
The USB protocol includes the HID device class, which any USB device can claim to be. Within the HID device class is a category for digitizers. When an OS finds a USB device plugged in that claims to be an HID digitizer, the basic drivers in the OD take the info (X, Y, pressure, tilt, etc) that the device provides, and makes it available through it's own APIs. In Windows, the Windows Ink API does this. It's pretty recent, and I don't think too many applications use it.

The device can have a custom device driver, which communicates with another subsystem running on the host machine (on Windows it's called wintab), which then communicates with applications like Photoshop. Wintab exposes an API to applications to allow them to get events and info from the digitizer. Wintab is maintained by Wacom and is an open industry standard. Most hardcore stylus apps (photoshop, corel draw etc) use wintab to get stylus info.
The Wacom engineer told me that writing a device driver that will communicate with wintab is a very difficult and long process, and usually takes hardware manufacturers years.
On the other hand, exposing the Note's SPen data (X, Y, pressure) as a USB HID device is equally difficult - it requires writing some kind of virtual USB device driver, which fools windows into thinking a real USB HID digitizer is attached. This would also only make the SPen data available through Windows Ink, which would be useless for everyone uses real stylus applications.
So basically, this project is not very possible, unless someone can come up with a very clever way around all these problems.
In the meantime, I'm going to write a very simple S Pen compatible VNC client for Galaxy Note. VNC servers are cross platform (I use Ubuntu & Windows) and VNC clients are very straightforward. With SPen and palm rejection, this could at least allow someone to use the Galaxy Note as a drawing tablet, albeit with no pressure sensitivity.
I was afraid that what you report could be the outcome of your research.
Your points are very much reasonable and it's also equally reasonable that the Wacom technology, available on the GNote, cannot be so easily exploited as to make the GNote a valid substitute of a Wacom commercial and separately sold product.
Nonetheless your "limited features" project could be very useful for us.
I've recently experimented using Splashtop 2 HD: when opening a basic paint program (MS Paint) on my W7 PC and using Splashtop 2 HD on the GNote it's possible to make drawings with the S Pen.
With this app the pen's responsiveness and accuracy is not bad, but also not completely satisfactory (but I can understand that's not the main scope of such an app) and, of course there's no pressure sensitivity...
Anyway, all this means that it's really possible to have some features of a graphics tablet through the GNote and there's a possible way to go.
I think that an app specifically designed for that could have a very good performance (and ways better than what you can achieve with a generic "remote desktop" app like Splashtop 2 HD) and a good response from Gnote users.
But, for sure, if anyone could find a smart way to read (or simulate) the pressure sensitivity, it could be a wonderful advance in the desired direction.
air display
I use air display and sometime idisplay as an input device with the PC and Mac at home. It turns your phone into a second display, but the lag is noticeable.
air display - works on ios, android, pc and mac
idisplay
If your project install the driver direct on the PC, that would be really wonderful!
Im guessing this forum is meant for software primarily, but im gonna ask this anyways.
If there is a seperate forum for this, i apoloize, but this is primarily a software question.
In theory, shouldn't it be possible to take out the electronics of a phone and hook up a bigger screen and larger battery to convert it into a tablet? I have a LG G6 lying around with a busted screen and a battery that lasts a total of 3 hours, so selling isnt worth it, disposing even less since id pay money to for that. The idea then is to take the completely functional motherboard, get a screen and a battery and 3D print a body that can accommodate it all.
Now the question: is there some sort of hardware ID or driver thing going on for either of the two things? Is it even locked? This is more out of curiosity, but if it is possible, i would try it out if i have the time.
Are batteries that large even available for purchase?

You can't really o that to a phone because the screen will not match
The flex won't match
And the body.

Thats not really the point of the question. It would be put into a custom printed body, maybe i can even manage to mold it somehow. Since the diagonal of the screen is somewhat irrelevant to the software, that shouldn't be a problem either, and finding an 11 inch 2880x1440 screen shouldn't be that hard. The question is if the rest of the phones hardware would recognize there is a screen there, even if its a bigger one. Im not quite sure what "flex" is supposed to mean, but fitting the parts together won't be a problem.
I would imagine it would be harder to get the phone into permanent portrait mode, but Nova Launcher for example doesnt even require root for that. The resolution, if 1440p 18:9 is required for some reason, this would be fixable with root. But the hardware itself is an issue.
So the real question is has anyone ever modified his phones actual hardware?
*edit*
By flex you mean the ribbon cables, right?
This, too, should be possible. Unless LG went to extreme lengths to design a custom exotic connector, im fairly sure you can get it to work as long as the hardware will still recognize it.
You would have to have a phone, like a Samsung, who has the video section separate from the main CPU body. I found the Voyo computer use the Samsung video driver for tablets on their tiny CPU boards. While nice CPU's (Deca-Core) the video out would be an issue.
You would also run into video driver issues with the ROM.
Then there would be the touch screen modules you would have to convert as well (along with software in the ROM).
What you might want is an OTG to HDMI adapter. Run a bluetooth mouse and keyboard and drive the HDMI on a big screen. Problem solved. If you want it portable, then the best advice is one that was already given....
....get yourself a tablet....

If you were to physically make it work, it would still require compiling a custom kernel with support for the screen added to the kernel. The kernel is what allows your software to use your hardware, kinda like drivers on PC except the drivers are built into the kernel instead of installed separately. You can't just install what the screen needs, it has to be built into a whole new kernel compiled from source and then you've got to get the kernel working with the whole device, not just the new screen.

Which would explain why there arent any results online for people doing this. Its way beyond the scope of what could be considered worth it.
Anyways, thanks

Getting a decent tablet would cost me a couple hundred quid, especially one with that hardware. Also it wasn't solely necessity, if i would just need a tablet, i would indeed buy one, but it was also to see if it could be done. Might very well have been a first. Also it would have allowed for some decent creativity. Sadly, were just not there yet, if we ever get to that point where smartphones will have the level of customizability of even a half decent laptop. Things like Project Ara would have been perfect for this, but sadly, money won over innovation
