[solved] mouse cursor not visible

m.vel

Hei All,

I have designed an experiment with a mouclick response. The participants will hear two short audio clips and choose which one describes the scene better. I have set the mouse cursor to be visible in the response, but it is not. It is important to have it visible because the participants have to be aware of where they are clicking.

I also included a touch response in case the participants are doing the task on a tablet, the cursor is set to visible also there. Could the two types of responses be interfering? I did try removing the touch response, but the cursor was still not visible.

I also would not mind if the cursor was visible at all times, if this was the alternative.

Does anyone know what could cause the cursor not to be visible? Thank you

Mouse pointer not hidden

Hi all,

I have an experiment where the mouse pointer is visible throughout the whole experiment, is there a way to hide it? I couldn't find anything in the documentation to do that.

I am not using the mouse_response object, or scripting anything with the mouse. It is only needed at the very beginning and the very end of the experiment, where I have inlines using the form widgets and checkbox rating scales. To tick the checkboxes of course the mouse pointer is needed, but apart from those two forms it is not needed at all, and should not be visible. But right now the pointer remains on screen during the whole experiment.

What would be the best way to do that?
Thanks and looking forward to your comments,
D.

Hi All,

Some time ago I had a similar problem, and (with Eduard's help) we fixed it by adding the following lines at the beginning of the the inline script (on the run sequence) that produces every trial:

    ### Hide Mouse
    ms = mouse()
    ms.show_cursor(False)
    ms.set_visible(False)

If you only use the standard OpenSesame objects, you can simply add an inline_script containing the mentioned lines at the beginning of your trial loop.

Hope that helps!

I hope it helps!

Hi,

(I'm helping Marta sort out some issues with her study.) An important detail here is that the experiment has to be exported to OSWeb. The proposed solution - inline Python script - is not supported by OSWeb, and inline Javascript doesn't support the creation of a mouse object.

Right, that is a problem. You might try a different backend, but beyond that I am also out of answers. Sorry!

Hi All,

Thank you for the suggestions. I tired all available beckends with no result. In all my mouseclick responses the visibility of the cursor is set to yes, and yet the cursor is never visible.

I would really appreciate any kind of advice as this has been delaying my research for way too long.

Thank you.

Hi @m.vel ,

Can you attach the experiment here? If in none of the backends the mouse cursor is visible, then I suspect that it's something in the logic of the experiment. But without actually seeing the experiment we cannot tell!

Hi Sebastiaan, sorry for the late reply. I have changed the experiment to collect a keyboard response, so that was my workaround. I also decided to go for the keyboard response because children are less proficient with the use of the mouse (due to touchscreens), so it was just easier to set up two response keys.

Thank you for your interest.

Hi Marta,

Maybe try a different backend? See here: https://osdoc.cogsci.nl/3.3/manual/backends/#mouse-cursor-visibility

Otherwise, you can attach your experiment and I can have a look.
