alfred3-interact: Interactive web-experiments in alfred3

Alfred3-interact is a plugin for alfred3. It allows for the creation of interactive web experiments, predominantly in the social sciences. As prerequisites, you need to have Python 3.7 or newer and alfred3 v2.2.0 or newer installed.

Installation

$ pip3 install alfred3_interact

Quick example

Below is an example script.py for creating an experiment with an asynchronous exchange of data between participants matching:

1. Initialize a group spec and the alfred3_interact.MatchMaker during experiment setup
2. Use a alfred3_interact.WaitingPage for matchmaking inside its wait_for hook method.
3. Find a group via MatchMaker.match and bind it to the experiment plugins object.
4. Now the group object is available in sections, pages, and elements through the experiment session object. You can use it to access data from other participants in the same group.

# script.py
import alfred3 as al
import alfred3_interact as ali

exp = al.Experiment()

@exp.setup
def setup(exp):
    spec = ali.SequentialSpec("role1", "role2", nslots = 10, name="mygroup")
    exp.plugins.mm = ali.MatchMaker(spec, exp=exp)


@exp.member
class Match(ali.WaitingPage):

    def wait_for(self):
        group = self.exp.plugins.mm.match()
        self.exp.plugins.group = group
        return True


@exp.member
class Success(al.Page):
    title = "Match successful"

    def on_exp_access(self):
        group = self.exp.plugins.group

        txt = f"You have successfully matched to role: {group.me.role}"
        self += al.Text(txt, align="center")

if __name__ == "__main__":
    exp.run()

The demo experiment can be started by executing the following command from the experiment directory (i.e. the directory in which you placed the script.py):

$ alfred3 run
