Docs > Results

The result file contains rows for each trackable mouse event that occured during your experiment's trials. We include all the participant's results in one CSV, which enables you to filter the results by a variety of factors.

The available columns are explained below.

Participant

The ID used by the participant to begin the experiment.

List

The name of the list that was assigned to the participant.

Trial

The name of the trial that this mouse event occcured in.

Condtion

The name of the condition that was specified by the list.

Type

The type of mouse event that occurred. This can either be move or click.

Target

The area of the stage that the mouse event occurred on. This can either be fixation, stage or the name of a layer or hotspot.

Trial start

A UNIX timestamp, in milliseconds, marking when the user began the trial.

Elapsed

The time since the trial start, in milliseconds, that the mouse event occurred.

X

The x-coordinate of the mouse cursor at the time of the mouse event.

Y

The y-coordinate of the mouse cursor at the time of the mouse event.

Timings

Timings are captured using the HTML5 performance API. On modern browsers (e.g. Edge, Chrome, Firefox and Safari) this produces millisecond timestamps accurate up to 5 microseconds.

Hardware or software contraints may produce timestamps without a microsecond component. Browsers that do not support the performance API will not run experiments.

Event frequency

Mouse events are broadcast by the web browser at varying intervals. Standard USB mice poll at 125Mhz (producing events at most 8 milliseconds apart), but the actual number of events broadcast per second will vary by browser, OS and mouse hardware.

Coordinates

Coordinates are reported by the browser, where 0,0 is the top-left of the defined canvas.

Where the browser reports sub-pixel coordinates, results have been rounded down to the nearest pixel.
