Data describing human-machine interfaces available to a user, facts relating to a circumstance of the user, a current human-machine interface being employed by the user, and an initial sentiment associated with the circumstance of the user is received. A target sentiment is computed based on the facts relating to a circumstance of the user. A navigation path to achieve the target sentiment based on the initial sentiment is determined. The next-best human-machine interface to be employed by the user is determined based on the navigation path, the one or more human-machine interfaces available to the user, and the current human- machine interface being employed by the user.
