Mapping unused Touch Screen Area to Soft Buttons / Commands

Hello,
I've got a resistive touch screen, where the touch area is larger than the display area. I'd like to map "soft buttons" (e.g. ESC or num block ENTER) to the area outside of the screen -- similar to androids [BACK], [HOME], [MENU] buttons at the bottom.
On the linux-side, the device is handled by AD7879-i2c driver -> /dev/input/mouse0. Using xinput_calibrator (creating some X rules), I can calibrate the mouse to the "display" area.
The two main questions are:
* can xorg (or modules / w/e) still see the absolute coordinates, that are outside of the screen? (Compare to "a window that's just outside of the screen is not clickable")
* is there a module that can map virtual hardware buttons to mouse-click-locations?
I'd love to do it in X because the calibration process using X and xinput(_calibrator) is very straight forward for the user.
so long..
Andy

Any pointers?
Ad. question 1: what is the command line to display ("debug") the (transformed) mouse events?
Ad. question 2: what's the best place to ask?

Periodically the home key and touch screen are unresponsive

Hi,
I have an iPhone4 and have recently noticed that the home key and touch screen are becomming less responsive. Sometimes I have to press the home key a few times to get it to respond also with the touch screen very rarely does it respond when i swipe to unlock or answer a call. The only way to get the swipe to unlock or answer to work is to press the sleep/wake button which is annoying if trying to answer a call.
Any suggestions?

it's the hardware issue.
someway you show may act the lifetime of Home button .

IPod Touch 16GB 1st Generation - touch screen area stopped working

Hello there, the last 2 days I'm experiencing a problem with my 16GB 1st Generation iPod Touch. One cm under the top of the touch screen and for about 10mm height, the screen is not functioning. I noticed this when I was on the AppStore and tried to buy an app. Exactly at the "Buy" button and on full width the multitouch screen doesn't work at all (touch/scroll/zoom etc.). I use OS 3.0 and I've installed it from my PC with the latest iTunes. I use the latest OS since it's release day and only yesterday the problem appeared.
The iPod is protected with silicon case since day 1, also has a screen protector and it's never dropped, scratched or anything that could cause this problem. I believe the problem/bug/dysfunction it's software related, even tho, I've restored the iPod erasing all it's data to the factory settings with the last OS, the problem remains.
Do you suggest me to downgrade back in version 2.0 and see what happens? Do I have to to downgrade to version 1.0? Please advise cause here in Greece the service doesn't exist as in the rest European countries and as in the rest of the world who has official Applestores.
I use both Mac and PC with my iPod Touch, so you can suggest solutions for both platforms. (Leopard/Vista)
I'm waiting for a response as soon as possible, thanks in advance and please advise me as an experienced user
The iPod Touch is bought from US and brought here in Greece on January 2008. It's the iPod with the January Update in case you're wondering.
Thanks for your time,
Vangelis Makridakis.

Seems that the problem isn't software related.
I've downgraded to 2.2.1 from 3.0 and nothing happen.
I can't buy apps from AppStore, I can't join a WiFi network and much more...
Apple made *faulty digitizers* (touch screens) cause as I've searched on the internet, many others have the same problem. Since it's out of warranty, Apple is covered... BUT customers should know that even if they don't drop their device or if they protect them, no matter what, one day they won't be able to touch some random areas of their screens.
As a customer _I demand answer_ and also a replacement program for faulty digitizers since will be confirmed that the customer never dropped or scratched the faulty device.
Also, since in Greece (where I live) we don't have Apple official representation as the rest of the European countries, I probably will have to pay A LOT to Rainbow S.A for a digitizer replacement and also to wait about a MONTH to get my device back.
Thank you Apple for making perfect products with the chance becoming lemons instead of apples.

HELP!! need to restart but home button and touch screen not working.

my ipod touch 5g wont let me slide to unlock. I want to figure out a way to restart the ipod wihtout using the home buttton or touch screen because my home button is broken. (ps. I have assistive touch on.)

Try:
- iOS: Not responding or does not turn on
When it says place the iPod in recovery mode
Place the iPod in recovery mode using one of these programs:
For PC
RecBoot: Easy Way to Put iPhone into Recovery Mode
If necessary:
Download QTMLClient.dll & iTunesMobileDevice.dll for RecBoot
and
RecBoot tip
For MAC or PC
The Firmware Umbrella - TinyUmbrella
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Soft Buttons not appearing on the 525G (UC520)

Hi,
We have installed a 525G2 on a clients phone system (UC520, Version 15.1(4)M60). The handset is working, in that it can make and receive calls. However there are no soft buttons displaying on the screen.
It has been configured with a template for the soft buttons that works for all the other phones on the system (mostly 504G). However its not working. I have tried restarting and a factory reset but it has not helped.
Can anyone advise?
Thanks
Adrian

Strictly speaking it's a bug in client server - items should not be able to directly overlay each other, unless only one of them is visible. (or you are using a stacked canvas)

Touch Screen Icons for dzen2

Hey guys,
touch screens are more and more prominent in the modern computing world so I'm looking for ideas and scripts to make them useful with dzen2.
As you might know dzen2 (SVN) does support stackable, clickable areas using the ^ca() command. That way it's extremly easy to create simple
touch bars that will launch any command you could think of, e.g.:
echo '^ca(1,uzbl-browser)^bg(blue)^i(/path/to/uzbl.xpm)UZBL^ca()\
^ca(1,xterm -e mc)^ca(2,pcmanfm)^bg(green)^i(/path/to/filemanager.xpm)Files^ca()^ca()'\
| dzen2 -p
The above code will create a simple dzen bar with two items, Uzbl and Files, when clicking with the left mouse button into the former it will spawn uzbl.
While the latter will either launch mc when cliked with the left button or pcmanfm when clicked with the middle button.
So what I'm looking for is icons suitable for touch screen use and ideas on how to integrate dzen2 into touch scenarios.
Some already available custom icon packs can be seen here: Dzen icon packs
Thanks for your attention, Rob.

Have you tried your good friend Google?
I found this during a quick search: Add-On Touch Screens
I am sure there are plenty of companies that make such devices, the only concern being that it is both Mac-compatible and of a desirable color.

Touch screen & Forms10g

Hello all,
i am looking for some help here on how to use a touch screen to run one specific form. we have one employee survey form developped in 10g, now we are asked to put the form in the touch screen monitor environment . so my questions is will oracle forms work with the touch screen (will the when-button-trigger fire automatically when pushing the button thru the touch screen) ?, is anybody implemeted the touch screen feature with the forms application?
Any help would be greatly appreciated.
Thanks in advance.

I tried this like 4 years ago with a lenovo tablet that was multitouch and my recollection is that one would really have to be able
to customize things more than I have a feeling it is going to be feasible to do. I think you should look at this from the perspective: "we'll test forms for this and if it is not going to be up to the task we are either going to change the idea of supporting touchpads or we going to use a different type of application to do this". Touchscreen as I recall generated mouse events. How there could be a problem is that the pointing device,
a stylus and/or an actual finger is bigger than a mouse pointer and not as precisely moved and "clicked". So basically some things would have to be way bigger for touchscreen. e.g. checkboxes and radio buttons and other buttons. I never got any useful advice about how to deal with
this back in 2007 when I brought this up. You are definitely not going to be able to do this without one or more touchscreens of the
sizes and types the users would be using.
Nowadays I think things are even more complicated as you have to know what platforms the users are expecting to run this on.
There is no forms for android or ipad, right?

Track pad and touch screen stopped working

My phone was out of charge and it turned out as soon as i plugged it in the charger but i noticed that neither my track pad or touch screen are working. i tired removing and putting back the battery and restarting it but with no use please post the solution asap thankyou.

Hi and Welcome to the Community!
Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain directly connected to a known-good wall charger (not PC USB, not a cradle):
With the battery inside, connect your BB to the wall charger
Leave it alone for 2 hours, no matter what the LED or the display does
Remove the battery
Wait 15 minutes
Insert the battery
Wait another 2 hours, no matter what the LED or the display does
This has been known to "kick start" some BBs.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
Obtain an known good and already fully charged additional battery...use it in your BB and see what happens
Obtain access to a known good and identical BB...use your battery in it and see what happens
The results of this will indicate if it's your BB or your battery that has the problem. Note carefully please that "new" and "know good" are not necessarily the same things. While rare, a "new" battery certainly could be defective. Rather, the simplest (and least costly, btw) method to conduct this test is to find someone with an identical BB who has no issues...trade batteries and see what happens.
Good luck and let us know!

LaserJet Pr0 200 color MFP M276nw Touch Screen not Working correctly

Hello, I'm having an issue with a LaserJet Pr0 200 color MFP M276nw Touch Screen not Working correctly. I have followed the instructions to reset the printer, but now am unable to select 'English' as my language because every time I select the 'English' option 'Spanish' is selected. I am then given two options to select 'Si' or 'No' both of which can not be selected on the touch screen?
Anybody know of a way round this?

Hi @dnhowes ,
I see that you are having issues with the touch screen not working correctly. I will do my best to help you.
Make sure the printer is connected directly to a wall outlet. (don't use a power hub or a surge protector) This ensures the printer is receiving full power and may help this situation.
Was it the Nvram reset back to factory settings that you tried or a hard reset?
Try selecting the option on the display a little higher above the icon to see if that helps. Some touch screens are finicky.
I find that on the Lab printers when I am selecting different menus.
If the issue continues, please call our technical support at 800-474-6836 for further assistance. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

Touch Screen Retrofit for iMac9,1 Screens

I am currently conducting research on virtual organs using the Hauptwerk/Classic MIDIworks systems. These are heavily dependent on touch screens. According to Darryl Wood of Classic MIDIworks " . . . there are a lot of switches inherent in organs. There's no way to implement that many physical switches, multiplied by all the different sample sets, practically or economically." This is why touch screens are recommended. That is to forgo the expense of independent drawknobs ($25 to $50 each) to say nothing of all the pistons, couplers, swell shoe displays and memory level displays that would cause a $7,000 organ project to drastically escalate in cost. I have found a retrofit in the form of the 3M MicroTouch System 3250EX. This is a surface capacitive touch system based on the 3M MicroTouch Controller EX and optimized for displays ranging from 6.4 to 32 inches.
If you do not recommend the 3M system, please send a list of touch screens and necessary connection hardware.

Hi @Bobi617 ,
Welcome to the English HP Consumer Forums!
Please feel free to post a revised message in English.
I understand you are having issues after a possible update on your HP Notebook and your touchscreen not responding. You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook.
When performing a System restore please note remove any and all USB devices. Disconnect all non-essential devices as they can cause issues.
Here is a document on troubleshooting the Touchscreen if the system restore does not help.
Thank you, and have a great day!

Miix 10 Windows 8 Touch screen problem

I am using this tablet for last 5 months. There was no problem but I faced a problem with the upper part of the touch screen. About 1.5 cm lenth of upper part of screen is not working. The rest is ok. There is no problem with display but I cannot click on that part.
First I think that maybe I have changed some setting accidently but I couldn't find any related setting about defining the touch screen area.
Is there any solution or do I need to change the screen ?

hi NetSurfer,
AFAIK, Windows 8 has an INF driver database that automatically installs the Touch Screen driver whenever a touch screen capable device is installed (it's like a usb device that's plug and play).
If you're having issues with the Touch Screen, try to:
1. Calibrate the Touch Screen (see page 18 of the User's Guide)
2. If you're getting touch screen insensitive issue, check this article.
Hope this helps.
