A body language system for determining a body language message (40, 40') of a living being in a context (48, 48'), said system comprising an artificial intelligence system, said AI system running a computer program that: - retrieves at least one image (45, 45') of said living being showing body language, wherein said body language comprises a body language gesture and a body language pose; - labels said living being in said at least one image (45, 45'), resulting in a labeled living being; - determines said context (48, 48') from said at least one image (45, 45') using a trained machine learning model (33, 33'), wherein said context (48, 48') is an environment in which a living being is positioned, in particular said environment is set by at least one selected from a location, an event, an object, another living being, weather conditions, light conditions, road conditions, and a combination thereof; - determines a baseline body language (46", 46"') of said labeled living being from said at least one image (45, 45') using a trained machine learning model (33, 33'), wherein determining said baseline body language (46", 46"') comprises determining body language characteristics which are specific for a group of living beings including said labeled living being; - adapts a trained machine learning model (33, 33') of said AI system using said baseline body language (46", 46"') and said context (48, 48'), the adapting comprising categorizing said baseline body language into a category based on said context; - applies the adapted trained machine learning model of said AI system to at least one of said at least one image (45, 45') for categorizing said body language resulting in a category, and applying said category for determining said body language message (40, 40'), said body language message conveying said body language. - retrieves at least one image (45, 45') of said living being showing body language, wherein said body language comprises a body language gesture and a body language pose; - labels said living being in said at least one image (45, 45'), resulting in a labeled living being; - determines said context (48, 48') from said at least one image (45, 45') using a trained machine learning model (33, 33'), wherein said context (48, 48') is an environment in which a living being is positioned, in particular said environment is set by at least one selected from a location, an event, an object, another living being, weather conditions, light conditions, road conditions, and a combination thereof; - determines a baseline body language (46", 46"') of said labeled living being from said at least one image (45, 45') using a trained machine learning model (33, 33'), wherein determining said baseline body language (46", 46"') comprises determining body language characteristics which are specific for a group of living beings including said labeled living being; - adapts a trained machine learning model (33, 33') of said AI system using said baseline body language (46", 46"') and said context (48, 48'), the adapting comprising categorizing said baseline body language into a category based on said context; - applies the adapted trained machine learning model of said AI system to at least one of said at least one image (45, 45') for categorizing said body language resulting in a category, and applying said category for determining said body language message (40, 40'), said body language message conveying said body language.
