Q. What is iGraphTablet ?
A. iGraphTablet allows you to simulate a Graphics Tablet with an iPad or iPhone. The picture of your computer screen appears on your mobile device and you can move the mouse cursor with your finger
Q. How does it work ?
A. iGraphTablet is composed of two components : iGraphTablet and iGraphTablet Server. The first one must be downloaded via the Apple AppStore on your iPad or iPhone. The second can be downloaded here and must be installed on your Mac or PC. iGraphTablet Server is the bridge that allows iGraphTablet to display your computer’s screen on your mobile device and to move your mouse cursor.
Q. My computer doesn't appear on the server selection page, why ?
A. For iGraphTablet to work, you need to check the following :
- iGraphTablet must be installed and running on your Mac or PC Windows. Check the iGraphTablet icon next to your computer clock by clicking on it. If you have not downloaded it yet, you can do it here
- Your computer and your iPhone/iPad must be on the same network (the Wifi Network for your iOS device). If they are not, they simply can't see each other.
- Tap the refresh button on the bottom right corner of iGraphTablet on your mobile device.
- Be sure that your computer IP address and your mobile device IP address are on the same range. (the 3 first numbers must be the same, by example : 192.168.0)
- Be sure that no firewall is blocking the ports 50030 AND 50032 (since version 2.1) and that no other program uses these ports.
- Be sure to install Apple Bonjour Component (included in iGraphTabletServer setup). If you did not install it the first time, uninstall iGraphTablet Server with "Add/Remove program" and install it again (to be sure : make a right click on the setup and choose "Execute as administrator…" if your are on Windows 7 or above).
- be sure that your computer and your iOS device can communicate on the same WIFI network : check your iPhone/iPad IP address in General Settings/Wifi/Your_wifi_name/IP Address. Then on your computer click on Start/Run... Type "cmd" (without ") then enter. A black command window should appear : type "ping IP_address" without " and where IP_address is the ip of your iPhone or iPad (example : "ping 192.168.0.66") then press Enter. If it responds you should see 4 entries with a time in milliseconds greater than 0.
- Check that iGraphTabletServer is added to the exception list of the Firewall. Go to System Preferences / Security and Privacy / Firewall / Firewall Options... (you may have to click on the lock icon on the bottom left and provide your password to unlock the feature). If it isn't in the list, click on the "+" button and add iGraphTablet Server (it should be in your Applications folder). Of course, choose "Allow incoming connexions".
- Check that your computer and mobile device can communicate. For your Mac, go to System Preferences/Network: the IP address should appear on the right (by exemple 192.168.0.2). For your mobile device, go to Settings/ WiFi, tap the arrow to the right of the connected WiFi Network then you will see the IP Address (by example 192.168.0.4). On your Mac, go to Applications/Utilities and launch Terminal. Type the command ping 192.168.x.y where 192.168.x.y is the IP address of your iOS device. Then press Enter.
If communications between your computer and your device is OK, you should see multiples lines with a value in millisecond (type CTRL+C to stop the ping command or close the Terminal).
Q. I've made all of that but the server still doesn't appear: what should I do ?
iGraphTablet has a feature allowing you to connect to iGraphTablet Server by entering the IP address of your computer. On the server selection screen, tap the bottom left button (IP Connection). You will then be able to manually enter the IP address. Note that if nothing happens when you tap the Connect button, it means that your computer doesn't respond. Since v3.0, we added a "Test" button that allows you to troubleshoot furthermore. If the IP is unreachable, it will tell you. The same if the computer is reachable but iGraphTablet Server is not (meaning it is not launched or the ports are blocked by a firewall).
Q. What are the differences between normal and Lite version ?
A. The lite version is a trial version. At the time we made it we couldn't call it "iGraphTablet Demo" or "iGraphTablet Trial" because those two words were banned from use by Apple validation processes. Not sure it's still the case but either way we now can't rename it.
The Lite version is totally free. You can't create regions with it and you can't create your own shortcuts. Furthermore, it gives you the opportunity to try iGraphTablet only for 5 minutes at a time. After this period of time, iGraphTablet Lite disconnects and returns to the server selection page. You can then re-connect but you'll have to wait 1'30" before iGraphTablet Lite allows you to connect again. We know it's annoying, but it's precisely the goal of it, so that people can try iGraphTablet and then buy the full version if it's OK with them. We may be philanthropists, be we're very much like you: we need to eat and pay our rent :)
Q. How do I scroll the picture on my iPad ?
A. Press at least 2 fingers on the view and slide.
Q. I'm on Mac OS X and when I launch iGraphTablet Server I got a message telling me it isn't an application made by an identified developer and cannot be launched. Why and how to launch it ? 
A. iOS certificates and Mac OS certificates are now available with the same registration ! No need anymore to pay two registrations per year. We signed iGraphTablet Server with our certificate so that this annoying message won't be displayed anymore :)
Q. Does iGraphTablet support the sensitivity pressure ?
A. Short answer: no. Long answer: we're working on it.
The first problem is that there's no sensitivity pressure on the iPad, so it means using a pressure sensitive stylus like the Wacom Creative Stylus or the Pogo Connect. The second problem is that it seems really hard to achieve on Windows. So for now, it's wait and see...
Q. iGraphTablet worked before on the first iPad: is it still working ?
A. Unfortunately no. The programming tools supplied by Apple doesn't allow us to test our application on devices with on OS older than iOS 8.1. And let's be clear, the overwork to make iGraphTablet run on older systems was becoming huge, and the percentage of users using them has become really small. So sorry if your operating system is not supported anymore. But know that you still can use iGraphTablet version 2 by downloading an older release on the App Store (you can download the corresponding iGraphTablet Server version in the Archives section).
Q. What is the minimum configuration for my computer to run iGraphTablet Server ?
A. The minimum recommended configuration is double Core CPU at 2.66Ghz with 4GB of RAM. Let's be clear: the bigger your screen resolution will be, the better your CPU and RAM should be. But know that it works OK for us with an early 2009 iMac Core 2 Duo, 24 inches (1900x1200 pixels), with 8GB of RAM and running on Mac OS 10.11.
Q. What is the minimum recommended iOS device that can run iGraphTablet ?
A. We tried it on the first generation iPad Air (late 2013) and it works great. The same for an iPhone 6 (sept. 2014). It should work on older iPads and iPhones but could be slower (that depends too on your screen resolution, computer CPU power and of course available network bandwidth). If you find it a little slow, you can try to adjust the settings to lower the image quality and/or reduce the scale of the image. note that there's a "Show FPS" option in the settings of iGraphTablet that should help you find the better settings possible for your configuration.
