[open] Moving image stimuli on screen, saving their final location and the sequence of operations

kubakrukar

Hi!
I'm looking for a software that will allow me to design the following task (which is something between card sorting and sketch map drawing):

There'll be a 2d architectural layout of some space in the centre of the screen and on the side I want my participants to have randomly thrown set of images. I want to ask them to place those images on a particular place in the layout and to save the location of it, as well as the sequence in which they have done it. I was thinking that movement of images can be done as drag&drop but from other discussions in this forum I understood this might be difficult to implement in OpenSesame. Another way of moving images is by clicking/selecting an image and clicking in the place where it should be put.
Is this doable in OpenSesame, and if so, where should I dig to get more details?

Thanks a lot!

Hi Jakub,

It's certainly possible to implement this in OpenSesame (even with drag-and-drop), but it will require some Python scripting. Nothing overwhelmingly difficult, but still some. Therefore, I would start by familiarizing yourself with the basics of Python:

• http://osdoc.cogsci.nl/python-inline-code/about-python-inline-code/#learning

The next step would be to look at the Python libraries that are specific to OpenSesame, which are all documented on the documentation site. And of course you can post questions here on the forum if you get stuck!

Cheers,
Sebastiaan

Thanks Sebastiaan. Yes, using a general scripting language is the suggestion I got from other people too. Nothing left, but to start typing Thanks for offering help and I'll certainly write here again if I have any more specific problems.

Cheers

Hello,

I am new to Open Sesame and also interested in this stimulus drag and drop feature and was wondering if I could leverage some existing code and not reinvent the wheel.

Thanks

Hi Christophe,

Not being a programmer I actually ended up doing something else instead. For the task i needed there was no reason to record detailed timings so I created this quick-and-dirty solution:
I opened a plain powerpoint slide in the fullscreen mode with all toolbars disabled. My background image was loaded as the slide's background/watermark (non-clickable) and the drag&drop stimuli were loaded as regular images. I recorded the users performance with a free screencasting software in the background - this gave me the sequence of their moves which was all I cared about. This obviously is not automated and therefore not feasible for large sample sizes but did the job for me with much less preparation time required.

Good luck
Jakub

I am trying to make a similar experiment. I want my experiment to have multiple words presented on the screen, make them move and obtain mouse clicks. Any pointers will help.

Thanks,
