AbsoluteTouchEx

AbsoluteTouchEx lets you use your touchpad like a touchscreen, giving you absolute cursor movement just like you would get on a tablet. It is the next generation of AbsoluteTouch.

This project solves two major shortcomings of AbsoluteTouch:

• It only worked with Synaptics touchpads
• It was incredibly laggy on slower computers

AbsoluteTouchEx is compatible with almost any Windows precision touchpad, and is orders of magnitude faster than AbsoluteTouch.

WARNING

AbsoluteTouchEx, unlike AbsoluteTouch, behaves very much like a hack. It's able to achieve its blazing fast performance by injecting itself into the target process and hooking some Windows API calls to translate HID events into mouse events. In contrast, AbsoluteTouch ran in its own process and set the cursor position globally (that's why you had to disable raw input when using AbsoluteTouch). As a result, AbsoluteTouchEx may trigger some anti-cheat protection systems. I am not responsible if you are banned for using AbsoluteTouchEx.

Running the project

Requirements:

• Windows 10
• Windows precision touchpad drivers

Ensure that your computer is using a Windows precision touchpad by going to Settings -> Devices -> Touchpad. If your touchpad has precision drivers installed, you should see "Your PC has a precision touchpad." at the top. If you do not see this message, AbsoluteTouchEx will not work.

Download the AbsoluteTouchEx executable from the releases page.

Choose the correct version of AbsoluteTouchEx to run. You must run the version with the same bitness as the program that you are injecting it into, NOT the bitness of your operating system! x86 is for 32-bit programs and x64 is for 64-bit programs.

Make sure you have the Visual C++ 2019 Redistributable installed (again, for the bitness version that you intend to run, not for the bitness of your operating system). You can download the 32-bit version here and the 64-bit version here.

Extract atloader.exe and atdll.dll to the same directory, then run the following command:

atloader.exe <path to exe to load>

For example, to run osu! (which, for the record, is a 32-bit program):

atloader.exe %LocalAppData%\osu!\osu!.exe

Initially at program startup, absolute touch mode will be disabled. You can toggle it on and off by pressing SHIFT + F6. Make sure to enable raw input mode; AbsoluteTouchEx will not work without it.

To adjust the area of your touchpad that gets mapped to the screen, press SHIFT + F7 to enter calibration mode. Draw a rectangle on your touchpad around the area that you wish to use (simply touching the top-left and bottom-right corners is also sufficient), then press SHIFT + F7 again to apply it. While in calibration mode, your cursor will not move; that is normal.

To save your calibration settings, press SHIFT + F9. The next time you run AbsoluteTouchEx, press SHIFT + F8 to load your configuration.

Building the project

Requirements:

• Visual Studio 2019
• Windows 10 SDK and WDK (for HID libraries)

The project should open and build with no configuration necessary, assuming you correctly installed the dependencies above. A prebuilt version of Detours is included in the source directory; if you wish to update it you are responsible for building it yourself.
