Execute experiment with moving dots using plugins online with OSWeb?

MarjoleinT

For an online experiment the set up will be that one group will have several trials (while instructed to perform mental imagery) that include looking at a dot in the center of a blank screen ('eyes stationary condition'), and the other group will have several trials (while performing mental imagery) that include following a moving dot across the screen ('eye movement condition'). I found some useful plugins for building smoothly moving dots.

However, would it be possible to execute experiments built using these plugins (the one in the link below) online with OSWeb? Due to restrictions in the use of script. I find it difficult to foresee whether there are feasible work arounds for this.

Or would it be easier to use a different method when aiming to implement this in OSWeb, if at all possible?

Many thanks for any directions on this!

Hi @MarjoleinT

Unfortunately the feature set of osweb is still very limited. I think what you desire to do is simply not easily possible at the moment. OSWEB is built around [pixi.js](https://www.pixijs.com/), and that definitely has the possibility to display a moving dot. However, integrating such a thing with osweb's response tracking features is a much more complex thing to accomplish, and at the moment I don't really have any ideas on how to do this to point you in the right direction.

Perhaps other online experimentation libraries offer an easier way to construct this task. A quick google search came up with https://github.com/Shamay/online-dot-motion (jspsych) or maybe you can find something useful on https://expfactory.github.io/experiments/

Good luck!
