Abstract: A system and method for determining a vector of action based on a psychological state and a contextual state of a user are provided. The system utilizes signals generated by biological processes to determine a user's psychological state and utilizes environmental conditions to determine a user's contextual state. The signals are detected by at least one user sensor within a wearable device, and the environmental conditions are detected by at least one context sensor of the system. The contextual state and psychological state are analyzed to create a vector of action for the user. A vector of action instructs the system to provide the user with an interface action based on the contextual state modified by the psychological state. Because the system continuously determines a user's psychological and contextual states, the system may continuously provide the user with interface actions relevant to the user's current emotional state and environment.
