Inquisit Web Experiences ??

Hi all, 
due to the circumstances I might need to transition my experiment to Inquisit Web.
Does anyone have experiences with it ?
Does the scaling (display) differ and will I need to ask the participants to download anything before participating?

Thanks in advance!

Paricipants will have to download and install the Inquisit Player. Your online experiment's start page will prompt them to do so and offer the appropriate download for their device.

As for scaling, things will depend on how you coded your script.

Hi Dave, 
thanks for your fast reply!
How can I ensure that the scaling will be the same as on my own computer?

First you need to explain what you mean by "the same."

Do you mean the relative positions and sizes of the stimuli or do you need to work with absolute sizes?

Will the format change on different computers or will the position scaling stay as I coded it?

This depends on *how* you coded it. (I don't have any information from you on that.) What you should do to achieve consistent relative stimulus positions and sizes across different display dimensions and aspect ratios is to

(1) Specify all stimulus postions and sizes in your script in percentages.
(2) Specify a fixed /canvasaspectratio in the script's <defaults>.

Virtually all scripts available in the library https://www.millisecond.com/download/library/ are set up this way, so you can look at those as examples.

Thanks for the helpful advice.
