A tablet computer is a mobile computer with a touchscreen display, circuitry, and battery in a single device. Tablets come equipped with sensors, including cameras, a microphone, and an accelerometer, and the touchscreen display uses the recognition of finger or stylus gestures replacing the usage of the mouse and keyboard. They usually feature on-screen, pop-up virtual keyboards for typing. Tablets may include physical buttons for basic features such as speaker volume and power, and ports for network communications and battery charging. Tablets are typically larger than smartphones or personal digital assistants.

Javascript routine works on PCs but not on touchscreen phones or tablets:

Zakaria Acharki helped me at www.experts-exchange.com/questions/29129533 with a webpage I designed in 2012 to get it partially working on touchscreen phones and tablets.

Here is a link to the webpage modified so it doesn't send data to me: www.barnwellmd.com/PainDiagram/Testdrawing.html

But this routine which works great with a mouse on a PC does not work on phones or tablets:
function clearGray()
{
	var imageData2 = context.getImageData(0, 0, 700, 643);
	var newPixels = imageData2.data;
	for (var i = 0, il = pixels.length; i < il; i += 4) 
	{
		if((pixels[i] == 255 && pixels[i+1] == 204 && pixels[i+2] == 153) 
		|| (newPixels[i] > 235 && newPixels[i+1] < 150 && newPixels[i+2] > 75 && newPixels[i+2] < 110))
		{
		}
		else
		{
		   newPixels[i] = pixels[i];
		   newPixels[i+1] = pixels[i+1];
		   newPixels[i+2] = pixels[i+2];
		}
	}
	context.putImageData(imageData2, 0, 0);
	context.fillStyle  = "#CDCDCD";
	context.fillText("Referred pain",275,600);
}

Open in new window

This routine deletes the markings not on the body image when mouseup is fired.

This is what it looks like on the pc after swiping the mouse across the entire image: desktop imageThis is what it looks like on my phone after swiping my finger across the entire image:phone image
So on the phone, lines drawn on the image are not deleted outside of the body image.

What do I need to do to get this to work on touchscreens?
Thanks!

I have three Toshiba Encore 2 WT8-B tablets.   32 bit 8.1 Connected is the current OS
the tablets won't activate Windows with the imbedded keys.
Microsoft says the keys have been used too many times...Toshiba support blows.

so, if I want to upgrade Windows to get out of this mess....what is the proper ISO to upgrade a Windows 8.1 tablet to windows 10?

another option is trying to find a good key to enter - so, what kind of Windows 8.1 key works with Connected?

...this is a pain in the neck I just want to go away!

Hi , we just purchased a Samsung Galaxy Tab S4 ,and would like to know a few things before we use it...
 
1. What would be the best way to set it up initially?
2.Is there a way to trace the device if ever we lose it and it is offline ?

Any suggestions to make it more secure would be awesome .

Hi,

I have this as part of a different issue I posted here on EE, but that's gone quiet, and wanted to repost this as a new issue.

We have an online video having issues with the audio not being on by default.  This only occurs in IEv11.  I spoke with an MS Premier engineer and he mentioned it seems the code for the video is set to be disabled for tablets and enabled for desktops.  The newer laptops do have touchscreens available, and we were wondering if this then considers a touch-screen enabled laptop as a 'tablet' and so disables the sound toggle by default.  I tested several different laptops, and all of the touch-screen ones had the setting disabled, whereas the non-touch screen laptops had the audio toggle enabled by default.

I went through Device Manager and disabled/uninstalled the 'HID compliant touch screen'; no change.  I also went through and disabled several different 'touch' related registry entries (hkcu and hklm\wisp\touch), by setting them to 0; no change.

I checked the BIOS as well, and do not see any touch-screen related settings there.

Are there any other touch-related settings I should be aware of that can be disabled?

Thanks,

Good Afternoon Experts,

Just a general question really..

I have about 20 tablets that are being used by our employees who are out and about around the country.

I was trying to find out if there is a way to do a remote desktop connection to the tablets so that i can run maintenance jobs on the tablets.

Instead of the employees bringing them back to the office to have the maintenance jobs done to save time and effort.

We have some Dell rugged tablets with on board verizon cellular data. We want the tablets to prefer wi-fi over cellular data and, according to Microsoft, this happens as a default behavior. In our testing this is not the case. I know how to use netsh to configure priority for wlan or mba... but I am not seeing a way to configure wi-fi over mba. Do one of you have a solution to forcing a network preference for wi-fi over cellular?


Thanks!!

We currently have 200 android tablet devices in a CLOUD only environment, no on prem.

What i would like to do is for the tablets to have restricted internet access, what is the best way to do this? Do not want any app installation or the use of a subscription such as openDNS where there is a cost associated to it. Cant use free as there are restriction on additional entries (may be wrong)

Anyway, would love help with this and what I can do to achieve this, as I said we are cloud based and using MerakiSM MDM to manage these. Step by Step would also be appreciated.

Thanks

Hi all
We have a number of Android tablets, some of which are misbehaving. I need to be able to save (or send) the system logs (and maybe dmesg as well, if poss) continuously to the removeable SD card, or alternately, to send the logs out to an FTP server. Can someone help me do this please? I will not be able to "root" the devices.
Thanks in advance

Hi,

We have an Amazon Fire 7 tablet.

The plan is to use the Fire 7 tablet as a device to display information.

The problem is that when the tablet goes to sleep or runs out of power, the next time the tablet is turned on or woken up, the lock screen appears.

I would like to configure, with the use of an automation app, a function that will activate when the Fire 7 tablet displays its lock screen and automatically unlock by way of a swipe up action on the screen.

Is there an automation app that can do this, mainly a free app.

Thanks,
Robbie

Hi, I am a member of a website that has a number of AVI videos. I only use IPad Pro and do not own a pc/laptop.

I do not have access to ITunes. Is there a way I can watch these AVI movies directly from the website on my Ipad. I tried using VLC and input the http address but it does not seem to work.

Appreciate any assistance.

Looking for inexpensive but effective way to image/Manage Window 10 PC's.  We currently only have HP Laptops & Desktops & Fujitsu Tablets.  We had VDI but ultimately found it wasnt saving us enough time or money for our envirnoment.  We have around 30 Fijitsu Tablets,  160 HP Desktops & 60 HP Laptops.  I want to easily repair a Windows 10 OS setup & if possible customize the image as much as I can but can use GPOs to manage all other settings.  Thanks in advance.  SSCM is to expensive for us.

I work in a medium sized private school in asia. We're planning to get tablets for our students that can be brought home for their use. We would like to be able to enforce our school policies, will filter web content, and be able to control their internet access (to limit their access so they dont stay too much time. Can anyone propose any solutions?

Thank you

Learn the fundamentals of Angular 2, a JavaScript framework for developing dynamic single page applications.

I bought a Samsung Tab S3 (2017) and having problems connecting it to an external HDMI monitor.

1. Can you advise what I may be doing wrong?

2. What do I need to ensure I can display my TV or Projector or Monitor or similar as an extended desktop from my tablet?

3. Maybe I can use Chromecast but for my presentations I'll need access to streaming content from the internet (which if I use Chromecast my wifi will be used for casting and not for internet).

Please any clarification or advise will be grateful.

I would like to have an app developed for a home classroom.
The Master will set the questions on the main tablet, this will sent out questions to the kids tablet such as maths questions with multiple choice answers, when the answered, the result should go back to the master tablet so the person can see who answered first and who got it right or wrong.
This should keep all stats until end of day or end of session, then the final results displayed with all stats .

I am sure this is possible, but if I were to look for an app developer, what type of skills am I looking for ? also how much should I be looking to pay ?  (approx cost).

Thanks

On my iPad, I asked for the IOS11 update. Its has been 2 days now and I still get the Install button grayed because "You can install this update when your iPad is finished restoring from the iCloud backup".
I don't need my iPad to be restored and 2 days is much too long anyway. So I conclude it will never end.
What can I do to finally install the update?
Thanks

I currently use Apple Magic Trackpad with a Lenovo 8" tablet (Android 5.1) for a customized field Astronomy setup. I'm looking for a very specific size and resolution (7.75" to 8",  1024x768 ) to replace the current tablet, but have found that Apple Magic Trackpad compatibility is spotty at best. Compatibility varies not just within versions of Android but also within point versions and also manufacturers. I'm trying to find a method to predict Bluetooth Apple Magic Trackpad compatibility within a certain device without having to actually have the device in my possession to test it. Any suggestions? Thanks.
