Emotional Design for Children's Electronic Picture Book.

Picture book is beneficial for children in many ways. In this work, we aim to investigate whether emotional design in an electronic picture book can facilitate children with great multi-sense experience, improve comprehension of children and give children positive emotional experience during reading. We propose a novel PCE (Perception & Comprehension & Expression) model from the perspective of emotional design. First, at the level of perception, it provides interfaces of multi-sensory interaction function. Second, at the level of cognition, it builds some interactive scenes. Third, at the level of expression, it creates some high-level interaction modes based on emotion recognition and emotion feedback. And based on PCE models in practice, we propose an electronic interactive picture book for children (5–8 years old), named E-book. In user study, it is proved that, added emotional design, the electronic picture can not only bring children excellent sensory experience in reading, but also help children get better understanding about the context. Furthermore, it gives children pleasant emotional interaction.
