Is it possible to collect information about the device that the user is running experiments on automatically? I see that Psytoolkit recognizes browser type/versions on the intro screen, but I wonder if there is more than can be detected (such as screen resolution, or whether the experiment is accessed being accessed on a mobile phone, tablet, or computer).
If this can be detected automatically, is there a way to save this information for each person and/or use it in the context of surveys or experiments to customize the experience? For example, could screen resolution be saved as a global variable and sent to an experiment from a survey to control stimulus sizes?
Thanks for your help, and thanks very much for this extremely useful platform!

This information is saved in the data collection file. If you look at the raw survey files, you will see that the files starting with "s." contain information in the header about the screen wiedth and height of the browser.
Currently, the screensize cannot be used in experiments to base stimulus size on. I agree this would be a cool feature, although not entirely simple. For example, not all screens have the same aspect ratio and not all screen use the same scaling factor (which is relevant for mobile devices and high resolution screens). In the future, I will make it possible to simply "scale" the whole experiment.
If you have a specific wish list, please send the details to psytoolkit@gmx.com and be as detailed as you can so that I can consider it in a future version.

Thank you for the information! As a workable solution, I've picked a resolution (320x480) I expect to be small enough to fit on most mobile screens.
