Running OpenSesame via browser

brt123

Hello! I am currently planning an experiment and I would like to know whether it is possible to run an OpenSesame - Experiment through a browser (as demonstrated in this Video: ), WITHOUT having OpenSesame installed on the computer in question but with still being able to record reaction times? My problem is as following:

My university uses E Prime to conduct experiments. The licences are limited and I won't have enough time to construct the experiment in the time when our library is open.
I would like to use OpenSesame but I suspect I won't have the permission to install any new software on the computers in the lab. This is why I would like to try this alternative.

P.S.: As I have now seen in the description of said video, OSWEB is not yet available of end-users, but maybe there's another way to achieve this? Or are there any alternative suggestions regarding open software to do this?

P.P.S.: As an alternative, I would try to use an old laptop of mine running linux to run the experiments. The issue I see here now is that reaction times might not be recorded reliable fashion due to "weak" hardware. Could that be the case?

Sorry for asking so many questions in one post, I can split this up if you want me to.

Thank you for reading

Hi,

If this is your main goal, then there is no problem. You can simply download the "No installation required" version of OpenSesame, which as a .zip file, extract it somewhere, and run it. You don't need admin privileges for that.

Does that work for you?

Cheers!

Hi,

I'm sorry if I've missed the information somewhere before but when do you expect that OSWEB will be available? Do you think it might be ready mid-2018?

Many thanks!

I just don't know, because it's a complex project, and coded by primarily others. So I prefer not to make any promises. The one thing that I can promise is that, once we're satisfied that we have a decent product, you won't miss it!

Hey Sebastiaan,

Thank you very much for your answer. Your answer below hit the point of what I wanted to to do!

Anyway one question still is open for me: Will I be able to track the reaction times of my participants in a reliable manner with this solution?
Also, will I be able to, let's say, program my experiment at home on the installed - version of OpenSesame and run the Experiment in the lab via the non-install version?

Thank you and have a nice weekend.

mvd this is the information I was lacking and therefore asked about this project

Yes, there is no difference between running an installed package of OpenSesame and a package that you have extracted from a zip. Provided, of course, that both are the same version of OpenSesame!

Thanks a lot for your answer and, in general, for this straightforward, open-source program!

Hello Sebastiaan,

This might come off as a stupid question but will the recording of the rasction times be just as exact when I run OpenSesame from my usb - Stick?
Didn't want to open a new thread for this, this is why I ask here...

Thanks so far!

Yes, that doesn't matter. Launching OpenSesame will be slower (because that requires reading from disk), but once running there is no difference (because things have been loaded in memory)!

Again, thank you very much! I think I should be done with my questions now!
