The system is in the company’s Emirai 2 concept vehicle at the Tokyo Motor show.

PinYin is the Romanisation of Chinese pronunciation, QuanPin predicts words based on the initial character and ShuangPin uses alphabetic input for each Chinese character.

There are cursor buttons and a jog dial and the LED display touchscreen leaves trace marks to enable a user to confirm what they have just written without having to check the console.

The touchscreen built into the steering wheel allows input with either hand and is curved to fit steering wheel contours.
