Online Experiments and Keyboard Input: Error sound in some Browsers

Psychopy Version: Standalone 3.1.0.

URL to Experiment:

Description of the problem: I’ve designed an online-experiment that needs the participant using the keyboard to give responses. It works fine in most browsers. In one browser, every time I press a key during the experiment, the computer produces a sound, namely the “you’re not allowed to perform this action here”-sound (for lack of a better word). Maybe this could be resolved somehow?

My current workaround is to require participants to use a browser in which this does not occur. I remember seeing a list of supported browsers at some point, but can’t manage to find it anymore. Does anyone have the link?

Tested browsers (on MacOS 10.14.3):

Safari 12.0.3: Produces error sound
Firefox 66.0.3 (64bit): works fine
Chrome 73.0.3683.103 (official build) (64bit): works fine

this still occurs in 3.1.2, haven’t figured out how to fix it.

I just tested and I find the same in Safari. Is very strange.

@apitiot any idea what could cause this to happen? Maybe Pixi.js doesn’t consume the key event fully so it gets passed to the browser which then complains?

Has anyone figured out how to fix this in Safari? I face the same problem.

@piet, which version of PsychoPy are you using?

I am using 3.2.4.

I have tested it in Safari 13.0.5, where it occurs, and Chrome and Firefox, where it does not.

Hi, same issue here on my Mac…is there a solution for that? Many thanks in advance.

I’ve got the same problem! (Safari 13.1)

This is also happening for me with Safari 12.1.2 and 13.1, running PsychoJS 2020.1

Any updates on this issue?

Hi, same issue here on MacBook.

I have the SAME problem. Newest version of PsychoPy, Pavlovia & everything. I’m using a MacBook (Catalina) & Safari.

How can this be fixed???

Thanks for flagging everyone, ON it! x
