During data collection, participants screen resolution were multiplied by the pixel density ratio, or devicePixelRatio (i.e. width = screen.width / devicePixelRatio = 1920 * 1.5). This was done with the intent of storing true device physical resolution. However to simplify analysis using webgazer, which uses the same initial value to calculate gaze location, participants screen resolution is reverted back to its original value.
