Character-by-character chat for autonomous vehicle support

An autonomous vehicle, comprising:

• a user interface device, wherein the user interface device comprises a touchscreen display;
• a processor in communication with the user interface device;
• and
• memory that stores instructions that, when executed by the processor, cause the processor to perform acts comprising:
• establishing a communication link between the autonomous vehicle and a remote computing device, wherein the remote computing device is disposed remotely to the autonomous vehicle;
• receiving text inputted through the touchscreen display of the user interface device;
• generating one or more outputs, wherein each of the one or more outputs define a character of the text;
• cryptographically signing each of the one or more outputs;
• and
• transmitting, via the communication link, the one or more outputs to the remote computing device as each of the one or more outputs is generated and cryptographically signed.

A method performed by a processor of a user interface device, wherein the user interface device is included within and in communication with an autonomous vehicle, the method comprising:

• establishing a communication link between the user interface device and a remote computing device, wherein the remote computing device is disposed remotely to the autonomous vehicle;
• receiving, through the communication link, one or more outputs from the remote computing device, wherein each of the one or more outputs from the remote computing device define a character of text and wherein each of the one or more outputs from the remote computing device is cryptographically signed;
• authenticating each of the one or more outputs received from the remote computing device as the one or more outputs are received from the remote computing device;
• and
• displaying the text on a character-by-character basis as each of the one or more outputs is received from the remote computing device and authenticated.
