Self-adaptive multimodal-interruption interfaces

Abstract

This work explores the use of ambient displays in the context of interruption. A multimodal interface was created to communicate with users by using two ambient channels for interruption: heat and light. These ambient displays acted as external interruption generators designed to get users attention away from their current task; playing a game on a desktop computer. It was verified that the disruptiveness and effectiveness of interruptions varies with the interruption modality used to interrupt. The thermal modality produced a larger decrease in performance and disruptiveness on a task being interrupted than the visual modality. Our results set the initial point in providing the theory behind future self-adaptive multimodal-interruption interfaces that will employ users individual physiological responses to each interruption modality and dynamically select the modality based on effectiveness and performance metrics
