Abstract: A centralized control system in an information interaction system has a communication module capable of transmitting audio signals such as by Bluetooth with a first and a second wearable device. When a user of the first wearable device is on a driver's seat and a user of the second wearable device is on a passenger's seat of a vehicle the centralized control system is capable of transmitting audio signals for the driver and passenger to speak to each other. The information interaction system can include a display screen and/or button for connecting, or rejecting incoming, calls through a mobile terminal. The information interaction system can also have voice command recognition functions, such as to control certain equipment of the vehicle or to make and answer queries through the mobile terminal.

Abstract: A centralized control system of a vehicle includes a control unit and a display screen. The control unit is capable of controlling the display screen to display instrument images and entertainment images in at least two different and switchable display modes based on at least two operating systems. In a first (instrument-focused) display mode, the instrument images and the entertainment images displayed on the display screen are both generated under control of the first operating system and an area occupied by the instrument images on the display screen is greater than an area occupied by the entertainment images on the display screen. In a second (entertainment-focused) display mode, an area occupied by the instrument images on the display screen is less than or equal to an area occupied by the entertainment images on the display screen, with at least some of the entertainment images generated by the second operating system.
