Method for planning actions based on an elementary attribute space

A non-transitory computer readable medium having a computer readable program embodied therein, wherein the computer readable program, when executed on a computing device, causes the computing device to perform a method for operating an assistance system based on an attribute space, the method comprising:

• obtaining task information defining at least one target state to be achieved by the assistance system;
• obtaining initial state information defining an initial state of at least one of an autonomous device or a user, and of at least one object involved in achieving the at least one target state;
• defining a planning problem based on the obtained task information, the initial state information and further based on attribute information related to the at least one object stored in a database;
• selecting, by a planning module, an action or a sequence of actions to solve the defined planning problem;
• and
• generating and outputting a control signal to at least one of a human-machine interface (HMI) for assisting the user in achieving the target state or one of the target states or to the autonomous device for achieving the respective target state;
• and
• the method further comprises:
• determining, by the assistance system, whether the selected action or sequence of actions achieves the target state, and, in response to determining that the selected action or sequence of actions does not achieve the target state, by the assistance system,
• decomposing the generated planning problem based on the attribute information stored in the database to generate a decomposed planning problem, and providing the decomposed planning problem to the planning module of the assistance system;
• solving, by the planning module, the decomposed planning problem;
• and
• generating and outputting the control signal based on the solved decomposed planning problem to at least one of the human-machine interface for assisting the user in achieving the target state or to the autonomous device for achieving the target state.
