Abstract

In a user-interactive system, such as an interactive voice response (IVR) system, the duration and/or force of key-presses by the user and/or the speed of response to prompts by the user are used to make inferences about the user, such as whether the user is impaired or is growing frustrated. The user interface is modified based on the inferences.
