This library makes an ACT-R Client available for .NET (>= 4.5) projects. It needs ACT-R Version 7.6 (currently in beta) or higher since this is the first version with the new JSON-RPC interface called dispatcher. I highly recommend to read the ACT-R RPC Interface Documentation for a better understandig how the ACT-R dispatcher works.
You can install the library to your project via Nuget:
Install-Package ACT-R-Client
Afterwards you can create an ActRClient object:
// since ActRClient implements IDisposal it can be used in an using block
using (ActRClient actr = new ActRClient("127.0.0.1", 2650)) // change host and port to your needs
{
// do what you need to do
}With this object you can interact with the ACT-R dispatcher.
For adding commands to the dispatcher you have to create an AbstractAddCommandRequest instance and send it to the dispatcher:
// add command
AbstractAddCommandRequest addCommandRequest = new AddCommandRequest(KeyPressAction, "published-name",
"private-name", "Documentation");
actr.AddDispatcherCommand(addCommandRequest);
// remove command
actr.RemoveDispatcherCommand(addCommandRequest);
// or
actr.RemoveDispatcherCommand("private-name");The AddCommandRequest is a implementation of the abstract class AbstractAddCommandRequest, which uses a simple delegate for command evaluations. Of course you can implement your own AbstractAddCommandRequest class to handle the evaluation requests from the dispatcher as you want to.
Adding a command monitor is very similar to adding a command:
// add monitor
MonitorRequest dispatcherMonitor = new MonitorRequest("command-to-monitor", "command-to-call");
actr.AddDispatcherMonitor(dispatcherMonitor);
//remove monitor
actr.RemoveDispatcherMonitor(dispatcherMonitor);
// or
actr.RemoveDispatcherMonitor("command-to-monitor", "command-to-call");There are about 100 implemented "ready to use" methods for the most common ACT-R functions, like load-act-r-model, reset, run, ...
// load model
actr.LoadActrModel("ACT-R:tutorial;unit2;demo2-model.lisp");
// reset ACT-R scheduler and model
actr.Reset();
// open experiment window
Window window = actr.OpenExpWindow("Letter difference", true);
// add text to experiment window
actr.AddTextToWindow(window, "A", 125, 150);
// install device
actr.InstallDevice(window);
// run model
actr.Run(10, true);At the moment only a few are tested, so erros can be occure (please let me know if you found one and i will fix it). If you want to make a different request you have to implement the abstract class AbstractEvaluationRequest, adding all necessary parameter to the given parameterList within the AddParameterToList method. This AbstractEvaluationRequest can then be send to the dispatcher.
// example AbstractEvaluationRequest implementation for the "my-command"
public class MyCommand : AbstractEvaluationRequest
{
public MyCommand(int intPara, bool boolPara, string stringPara, string model = null) : base("my-command", model)
{
IntPara = intPara;
BoolPara = boolPara;
StringPara = stringPara;
}
public int IntPara { set; get; }
public bool BoolPara { set; get; }
public string StringPara { set; get; }
public override void AddParameterToList(List<object> parameterList)
{
parameterList.Add(IntPara);
parameterList.Add(BoolPara);
parameterList.Add(StringPara);
}
}
// let the dispatcher evaluate my-command
AbstractEvaluationRequest myCommandRequest = new MyCommand(0, false, "StringParameter");
Result result = SendEvaluationRequest(myCommandRequest);The Example Project contains some implementations of the ACT-R tutorials.
