Force-based interactions with digital agents

Embodiments relate to enabling force-based interactions with an intelligent personal assistant (IPA). A computing device capable of sensing the force exerted to input touch inputs is configured with a pressure-based filter that checks pressures of touch inputs to determine which touch inputs are to be diverted to the IPA or which are to be passed on to underlying user interface that is not related to the IPA. Touch inputs designated for the IPA based on their pressure characteristics can become part of the context of the IPA. Some IPA uses of the touch inputs include selecting graphic objects on the display, resolving exophoric phrases (e.g., "that", "those") as referring to such selected graphic objects, displaying transient user interface to provide information about (or actions for) the selected object, incorporating a selected object into the current context of the IPA, etc.
