A virtual reality (VR) headset face cushion that includes a capacitive fabric is described. The capacitive fabric is connected to a smartphone’s touchscreen placed within the VR headset. The connection allows the smartphone to determine whether the user is wearing the headset by detecting the difference between the capacitance when the face cushion is touching the user’s face and when it is not touching the user’s face. When the smartphone detects that the user is not wearing the headset, it can pause the VR application and/or dim the smartphone screen, which increases battery life and improves the user’s experience.
