Abstract:
A method of enhancing interaction between a user and a machine, said machine comprising (i) a sensor unit for detecting a user, (ii) a data processing unit for extracting features of the user under predetermined rules, (iii) a memory, (iv) a second sensor unit for detecting a user's action, (v) a behavior decision unit including a behavior decision algorithm programmed to select the machine's action when receiving designated signals, and (vi) an actuating unit for actuating the selected action, said method comprising the steps of:(a) detecting a user by the sensor unit, extracting features of the user by the data processing unit, and recording the features of the user in the memory; (b) interacting with the user, detecting the user's action by the second sensor unit, and saving the user's action in the memory in relation to the features of the user, wherein the machine behaves using the behavior decision unit and the actuating unit; (c) determining whether any user having features identical or similar to those of the user is of record in the memory, and if any, updating the features of the user of record by statistical processing, and recording the updated features of the user in the memory in relation to the user's action; and (d) modifying the behavior decision algorithm in accordance with the significance of probability of identifying the user based on the statistically processed features of the user, whereby outcome of the machine actuated by the actuating unit changes based on interaction between the user and the machine.
