Touchscreen mouse emulation

Dunny · 12 April 2010, 12:38

Over on the GP32X forums, I've been informed by Mr Craig Rothwell that patching an amiga emulator to use a touchscreen to control the mouse is likely impossible.

I disagree - I envisage a system that translates touchscreen coords into mouse movements (a displacement from the current mouse pointer coordinate to the new position). This would be quite easy for say, intuition, and might be a tad more involved if you're running a game, but I think it should be easy enough to do.

Any thoughts? I mean, it's not like it's impossible to detect when a game reads the mouse, is it? You just supply your values instead of the real mouse coords/delta.

In particular, Toni, what are your thoughts on this? I'm not asking for it in WinUAE, but I need to know how difficult it would be in general under emulation.

Well, WinUAE works already with my LCD tablet, so. I guess what is needed is to translate the Wiz pen movements to mouse coords the same way my tablet's driver does? And then it will work as a mouse. As for games, well a mouse is relative and a tablet is absolute. So defo more work. But I think pre-translating the pen input instead of patching the emulator has a better chance. Doesn't the Wiz pen already work just like a mouse?

No idea

This is for the Pandora.

I've already said that games will require a case-by-case solution, but overriding the games' behaviours without necessarily modifying the game code. I'd love a version of carrier command that used the touchscreen properly...

Not sure if it's a problem, as such, I'm just looking to explore the possibilities of modifying one of the UAE branches for that platform.

Touchscreens will still use a PS/2 protocol for the mouse movement, so I wouldn't have expected any nasty surprises with the pointer. I'm not sure about the button clicks though....

There is no way to have generic game compatible absolute mouse to relative mouse conversion and I don't like game specific hacks, sorry.

System friendly software works perfectly fine with built-in "mousehack" input handler. (was external in older versions)

Why not just translate dragging to mouse movement?

I mean you can't point and click then, but I could imagine it being convenient enough once one gets used to it, and if the speed is adjustable. Kind of like a combined screen/trackpad.

I wasn't asking you to do it - I just wanted to figure out how possible it is. If I need to modify UAE sources to do it, I'll do it myself

Is there a way to use WinUAE with NEC AS221WM monitor and Windows 7? Amiga pointer is at random position with each touch.

WinUAE 's pretty random with a Fujitsu P16xx series laptop's touchscreen too, sadly. I was hoping to rip some pixels using DPaint, but no, it wants to jiggle back to the lower right corner on first contact.

You need Amiga-side driver for touchpads or any other absolute pointing devices, real or emulated Amiga.

Enable "Virtual mouse driver" (Checkbox in Game Ports panel). This is improved old mousehack option.

You can try to use a software that is named Cok Free Mouse Emulator to contorl your touchscreen.
