Script error on my pavlovia experiment on tablet

[Magicdjez]

Hello,

I am trying to develop an image recognition experiment on Pavlovia. The final goal of this experiment is for it to be performed on tablets by participants, who will be children. My current prototype works on a computer, but when I try to run it on an iPad, I get the following error:

The experiment works as follows: participants are presented with four images and a sound describing which image they need to click on. They must then select the correct image. Here is an example of one of the tasks:

How can I make my experiment run on a tablet when everything works fine on a computer? I saw a similar error on some topics, but it was related to forms, and I didn’t understand the answer (rating type question and dropdown question).

Thank you in advance!

The unknown component niveau2_2 suggests that you have an experiment created in 2024.x which you have then opened in an earlier version.

Wakefield's Daily Tips

Use Routine Settings As of 2024.1.0, each standard routine includes its own settings, accessed by a cog in the top left. [image] Routine Settings includes five tabs: Basic, Flow, Window, Data and Testing. So far I have mostly used the Flow tab to either add a duration to the routine or a “skip if” condition. [image] Routine durations are easier than adding durations to every component in the routine separately and works even when a component hasn’t been started because its start condition…

What version of PsychoPy are you using?

Use the topic template I’ve just updated the topic template for the Builder category and copied it (with minor edits) to the Online category. Please answer the questions on the template. OS (e.g. Win10): Macs can be particularly tricky. Older versions of Windows may need older versions of PsychoPy. PsychoPy version (e.g. 2024.2.4 Py 3.8): Your issue may have been fixed in a later version, or may work better in an earlier version. Standard Standalone Installation? (y/n) If not then what?: Cu…

Thanks for your answer.

The unknown component is something that was created when I pushed my experiment to Pavlovia. I haven’t changed my version of PsychoPy since I created this experiment.

I used version 2024.2.4. Do I need to upgrade it?

[JensBoelte]

Hello

You are running the experiment in a browser. What version does Pavlovia recognize, see example?

Do you need the component niveau2_2?

Best wishes Jens

I think this could only have happened if you had a pre Routine Settings version set in Experiment Settings.

Wakefield's Daily Tips

Locate Experiment Settings In versions prior to 2025.1.0, one of the most important menu items didn’t actually appear in any of the menus. You could only access it with a mouse by clicking on the cog icon. [image] From 2025.1.0 onwards it is also accessible from the Experiment menu and via a keyboard shortcut (Ctrl-Shift-X) [image] Experiment Settings itself has seven tabs. [image] General is used to define expInfo dialogue box variables and set the PsychoPy version (leave blank unless …

I run it on this version

Nothing change when I remove it

[Magicdjez]

What’s a pre routine settings ?

[wakecarter]

I mean a version of PsychoPy that comes from before Routine Settings.

Since your platform version is 2024.2.4 then probably what happened is that you edited a recent psyexp file with an older PsychoPy and later opened it in the recent version.

[Magicdjez]

Ok, I understand thank for the explanation . I removed it, and now my experiment works on my tablet except for the mouse component. Do you know how I can fix this?

[JensBoelte]

Hello @Magicdjez

How do you use the mouse-component? What does not work?

Best wishes Jens

[Magicdjez]

This is a picture of the component options. The goal is to click on one of the four images. On my tablet, the click doesn’t work, and nothing happens. I saw in some previous topics that sometimes you need to click twice or press harder, but that doesn’t work in my case.

Thank you for your help,
Djeser

Does this mouse component work as expected on a computer?

The tablet you are using may not be recording clicks correctly. If that is the case, then you could instead have the following code:

Begin Routine

mouseRec = mouse1.getPos()
response = 0

Each Frame

mouseLoc = mouse1.getPos()
if t < .05:
     pass
elif mouseLoc[0] != mouseRec[0] or mouseLoc[1] != mouseRec[1]:
     mouseRec = mouseLoc
     if img1.contains(mouse1):
          response = 1
          continueRoutine = False
     elif img2.contains(mouse1):
          response = 2
          continueRoutine = False
     elif img3.contains(mouse1):
          response = 3
          continueRoutine = False
     elif img4.contains(mouse1):
          response = 4
          continueRoutine = False

Skipping the image to be touched as response

OS (e.g. Win10): PsychoPy version (v2024.2.4): What are you trying to achieve?: I am running a touchscreen experiment on a convertible laptop. My goal is that during the instructions screen, the participant should be able to tap anywhere on the screen to move forward in the experiment. In my earlier version we used SPACE as a response to move forward in the experiment. In the current version I would like the participant to be able to tap anywhere on the screen or atleast on an image/text to m…

[Magicdjez]

It works, thanks a lot! It was a big issue for my project!

However, I get an error at the end. The entire experiment works fine, but I receive this message.

[wakecarter]

Do you have any End Experiment code, or End Routine of the final routine, or a redirect?

[Magicdjez]

Nope do I need to have one ?

[wakecarter]

No. I am looking for reasons for the error. You were using pilot mode, weren’t you? Try running mode. It might be that there’s an issue with piloting when it tries to download the pilot data.

[Magicdjez]

Ok i will try but I download a css file at the end of the experiment

[Magicdjez]

it works on running mode
