A vehicle-user interaction system for a vehicle, comprising: an editor configured to receive one or more inputs from a user of the vehicle and edit the one or more inputs into a rule script, the rule script comprising a user-defined rule based on the one or more inputs, the user-defined rule defining a trigger condition and a vehicle operation performed when the trigger condition is satisfied; a parser configured to create a list of monitoring elements and a list of functional elements based on the rule script, the list of monitoring elements comprising sensor elements that directly or indirectly sense the trigger condition, and the list of functional elements comprising functional elements that are associated with the vehicle operation; and an actuator configured to monitor sensor detection information associated with the sensor elements, determine whether the trigger condition is satisfied based on the monitored sensor detection information, and execute the functional elements to implement the user-defined rule in the vehicle if it is determined the trigger condition is satisfied, wherein the editor comprises an editing module configured to edit the one or more inputs according to a regular expression rule and a predetermined format to generate the rule script, wherein the predetermined format comprises first and second portions each having a fixed data length, and a third portion having a variable data length, and wherein the first portion sequentially includes a header having a length of 8 bits, an editor version having a length of 8 bits, an infotainment operating system version having a length of 8 bits, and an identification having a length of 8 bits; the second portion sequentially includes a data packet having a length of 16 bits and a reserved field having a length of 16 bits; and the third portion comprises a data field having a variable length. an editor configured to receive one or more inputs from a user of the vehicle and edit the one or more inputs into a rule script, the rule script comprising a user-defined rule based on the one or more inputs, the user-defined rule defining a trigger condition and a vehicle operation performed when the trigger condition is satisfied; a parser configured to create a list of monitoring elements and a list of functional elements based on the rule script, the list of monitoring elements comprising sensor elements that directly or indirectly sense the trigger condition, and the list of functional elements comprising functional elements that are associated with the vehicle operation; and an actuator configured to monitor sensor detection information associated with the sensor elements, determine whether the trigger condition is satisfied based on the monitored sensor detection information, and execute the functional elements to implement the user-defined rule in the vehicle if it is determined the trigger condition is satisfied, wherein the editor comprises an editing module configured to edit the one or more inputs according to a regular expression rule and a predetermined format to generate the rule script, wherein the predetermined format comprises first and second portions each having a fixed data length, and a third portion having a variable data length, and wherein the first portion sequentially includes a header having a length of 8 bits, an editor version having a length of 8 bits, an infotainment operating system version having a length of 8 bits, and an identification having a length of 8 bits; the second portion sequentially includes a data packet having a length of 16 bits and a reserved field having a length of 16 bits; and the third portion comprises a data field having a variable length.
