ABSTRACT
Haptic interfaces and graphical user interfaces can be persuasive, as we've seen, but verbal persuasion promises the give and take of natural conversation to steer data and feeling. One scientific challenge is for IUIs to understand the art of persuasion. IUIs will destabilise some identities or reduce the authority of others with consequences for PR and persuasion. When it comes to persuasion VUIs have several advantages over graphics, haptics or virtual reality. Interface research tries to understand these less tangible qualities of persuasion, which must accommodate multiple possible truths, since ‘Future intelligent systems may have contextual goals to pursue that aims at inducing the user, or in general, the audience, to perform a specific action in the real world’. Hoschka’s 1996 discussion of computers as assistants raised the need for computers to support and coordinate group activities, and develop mediating systems for supporting discussion, arguments and decisions.
