The Mobile Device Holder for Inspire 1 Quadcopter from DJI allows you to bring ground station and transmitter together in one unified system. This part is a clamp that holds mobile devices from smartphone up to tablet sizes that clamps onto the transmitter (radio controller). This gives you a convenient first-person view of the video feed from the camera plus OSD data. You can also use tablet to control camera settings and update autopilot flight parameters.
