UserActivityTracker 1.1.0

UserActivityTracker v1.1.0

A lightweight real-time tracker of user interactions for WPF. Support both mouse and keyboard actions. Able to save the tracked recording to a string value and play the recorded actions for UI/UX analysis. Support full window monitoring or a specified focus on a particular element. Support saving the initial size and other states upon starting.

Main Features

• Record user actions without worrying about different types of elements
• Record user actions with relative positionings
• Save the recording data to a string representation
• Play the recorded user actions whenever
• Specify a particular element for recording
• Save the initial size of the element upon starting
• Save additional customized configurations upon starting
• Save logging messages at anytime during recording
• Analyze and graph the recorded user actions

How to Use

Use UserActivityTracker.Recorder to record user actions:

//Start upon the window is ready. The ContentRendered event can be used, for example, to start the recording automatically.
UserActivityTracker.Recorder recorder = new UserActivityTracker.Recorder(this); //Set the element to be recorded to the window.
recorder.Start(); //Start the recording. Returns true if the recording was started successfully.

//Stop upon the window is being closed. The Closing event can be used, for example, to stop the recording automatically.
recorder.Stop(); //Stop the recording. Returns true if the recording was stopped successfully.
string session = recorder.Save(); //Retrieve the string representation of the recording.

Use UserActivityTracker.Player to play user actions:

MainWindow window = new MainWindow(); //Create a new window for the user actions to be played.
UserActivityTracker.Player player = new UserActivityTracker.Player(window); //Set the element to play the user actions to the new window.
window.Show(); //Show the new window.
window.ContentRendered += async (obj, args) => //Play the user actions when the new window is ready.
{
    if (!player.IsPlaying) //Check whether the playing has been started yet.
    {
        await player.Play(session); //Play the recorded user actions from the string representation.
        window.Close(); //Close the new window as the playing is done.
    }
};

Configurable Properties

Configurable properties of UserActivityTracker.Recorder:

recorder.FrameRate = 15; //The number of basic user actions that are recorded per second, including moving the mouse. The default value is 15.
recorder.OptimizeData = true; //Indicates whether to optimize recording data based on the frame rate. The default value is true.
recorder.RecordMouseActions = true; //Indicates whether to record mouse actions from the user. The default value is true.
recorder.RecordKeyboardActions = true; //Indicates whether to record keyboard actions from the user. The default value is true.

Configurable properties of UserActivityTracker.Player:

player.PlaybackSpeed = 1.0; //The multiple that is applied to the frame rate during the playing. The default value is 1.0.

Availability Status

Check whether the recording has started yet:

bool isRecording = recorder.IsRecording; //Indicates whether the recording has started yet.

Check whether the playing has started yet:

bool isPlaying = player.IsPlaying; //Indicates whether the playing has started yet.

Check whether the operation was executed successfully:

if (!recorder.Start()) //Start(), Stop(), and Play() all return a boolean value, with true indicating success.
{
    //Something wrong happened. The operation failed to be executed successfully.
}

Customizable Starting Configuration

Store a customizable string without the character ; that can be used again upon playing:

string startingConfig = textRandom.Text; //Use the content of the TextBlock as the starting configuration. This configuration cannot include the character ";" in it.
recorder.Start(startingConfig); //Start the recording with a customized configuration that can be used upon playing. Returns true if the recording was started successfully.

Play the user actions with a callback that uses the configuration string stored:

//Play the recorded user actions from the string representation with a callback that retrieves and uses the saved starting configuration.
await player.Play(session, (startingConfig) =>
{
    if (window.FindName("textRandom") is TextBlock textBlock)
    {
        textBlock.Text = startingConfig; //Use the retrieved configuration on the TextBlock.
    }
});

Log Information

Add a custom string message without the characters ; and ' to the recording that can be outputted to the logs during the playing:

//When a button is clicked.
recorder.LogMessage("Sample Button Clicked!"); //Log a custom string message into the recording.

Receive the current output of logs that have already been outputted during the playing:

string logOutput = player.LogOutput; //The available logs at the moment. 

Use the LogOutputUpdated event to receive log outputs at real-time:

player.LogOutputUpdated += Player_LogOutputUpdated; //Add a listener to the LogOutputUpdated event.

private void Player_LogOutputUpdated(object sender, LogOutputEventArgs e)
{
    Debug.Write(e.Update, "UserActivityTracker.Player"); //Write the received update to the debug window.
}

User Action Analysis

Analyze and graph the mouse actions within the recorded data:

Bitmap bitmap = UserActivityTracker.Analysis.TrackMouseMovements(session);

Recording Data Format

The saved string representation is in a format where attributes are separated with semicolons and include f(FrameRate), w(StartingWidth), h(StartingHeight), c(StartingConfig), and a(Actions). Each attribute uses a single-letter indication of the attribute that is followed by the value directly, minimizing the length of the string representation.

Actions is a string representing a list of UserAction that uses single letters to indicate the type of action, then action-specific parameters seperated by commas. All coordinates are based on relative positioning to the recorded element.
