I was kicking around and idea related to pairing a multiple desktop platforms with an Android tablet. Could you guys tell me if anyone has designed an application like I am about to describe?

I am thinking about a two part application that pairs your desktop computer with an Android tablet. The pairing allows users to use their Android tablet as a live preview and drawing surface for applications running on their desktop computer.

The intent is to provide better drawing and painting for desktop applications such as Krita, Gimp, Inkscape, and other applications by hosting a service on the desktop computer that forwards an image of the drawing surface on the desktop computer to an Android tablet, and translating touch or stylus strokes on the tablet to native commands in Krita, Gimp, Inkscape or other desktop programs. Translated commands might change the active layer, brush size, opacity, active tool (smear, clone stamp, airbrush, and so on) as well as stroke data (drawing, erasing, and such).

The part that is the desktop service would be designed to support a list of specific applications such as Krita, Gimp, Inkscape and so on (obviously this list could be expanded).

The part that is the Android tablet application would connect to the desktop service and display what it is told by the desktop service, and also forward stylus input to the desktop service.

Thanks for the link, but that's not at all the same. That's is just a mobile version of a desktop application.

What I was attempting to describe is a tablet application that provides a specialized input view to a desktop application using an android tablet. A tablet application that provides a adapted view and means to control an instance of Krita (or Gimp, or Inkscape, ect) running on your desktop. And I was thinking the means to do this would be through a desktop service (written using Free Pascal and Lazarus) that translates tablet input into commands specific to Krita, or Gimp, and also feeds the tablet with view data (what to display on the tablet as you work).

Anthony- Never heard of such an app. However, I'd like to ask: What is the problem this app is designed to solve?

Maybe RFB/VNC/RDP/X11 or something similar will be enough?

so in the most simple terms, you are wanting to use a tablet as a digitizer for a desktop system, right?

wkitty42,

Yes, I want to use a tablet as a digitizer for a desktop computer, but with a modification. I want the tablet to be able to have easy access to specific commands for programs, such as change brush shape, size, color, change the active tool, and change options for the active tool. The desktop service application would optimize the flow and interfaces for each desktop application to best suite a tablet (or digitizer) interface.

I would like to know if someone has already created this type of application for android tablets and also associated the service interface desktop computers.

gabor,

No, this would be more than a desktop VNC or screen duplication application. It would provide an simplified and optimized drawing interface to tablets with "tabletized" access to command for commands for Krita, Gimp, Inkscpae, and so on. The layout and usage of commands would be different for each program you are interfacing with based on how the desktop service application decides to best present those applications to a tablet, keeping in mind that the main function of the tablet would be to act as a drawing surface.

DougC,

This program would essentially give people who use Krita, Gimp, Inkscape and other desktop applications the ability to turn any android device into a drawing tablet for those programs. It would also differ from a digitizer in that the service application can be designed to provide an dynamic interface to these applications that would be better than any digitizers interface, since its view could be programmed to present commands and appear any way possible. I also could imagine designing the desktop service application in such a way that other programmers or even end users could customize the commands and views, and how the commands and view work, which they can see on their tablet.

Again, I am just trying to figure out if anyone has created something like this yet, and if not why.

It looks like this program is similar:

But it doesn't seem to translate tablet actions into program commands other than just drawing.

Thanks everyone for your feedback.

when i last used a digitizer for drawing (shapes/letters on signage vinyl to be cut with a knife plotter), the digitizer we used could be configured with an area for drawing and another area for access to the menus for changing the options... but we didn't do that... instead we used the digitizer like a common mouse. the pointer never had problems accessing any of the menus in the application... where ever the stylus went, the on-screen pointer went... we even stopped using and removed the mice on the workstations that had digitizers because they did the same thing and those users just used the digitizer for all mousing around... it didn't matter if it was in autocad or some other signage related drafting program or outlook or AOL or prodigy or whatever... the digitizer was just a different mouse...

I would like to know if someone has already created this type of application for android tablets and also associated the service interface desktop computers.

i cannot say that i've ever heard of one but i haven't used a digitizer in at least 20 years... to me it is still just a different type of mouse...

wkitty42,

The other thing a tablet would provide over a digitizer is that it can display an actual image of the work as you draw. Sure people could get used to drawing on a input device while watching their computer monitor, but drawing on a flat paper like device, while seeing their artwork on that same flat surface device would best replicate pen and paper drawing. Additionally, I could see the tablet providing ghosting drawing function while you draw to reduce the lag between the tablet and the desktop computer. That is the user could see his strokes in realtime while the desktop computer (service application) is busying performing work and serving screen updates. This way the work on the tablet would be much more fluid or smooth.

Also I found this person searching for the same thing:

In his summary section the above youtuber answers my original question with a NO, or at least non worth while. He expresses hope that application developers will fix the issues he brings up. Also all the existing applications seem to follow the same model I mentioned, and that is a tablet application which communicates with a special desktop application service.

In my opinion this looks like something that may warrant further research with Free Pascal and Lazarus. Again in my opinion they would be the best tools for developing a desktop service application for multiple platforms to handle the command processing and graphical view generation. -------------- next part --------------
