Furthermore, we WishBringer may reference childhood themes (e.g. teddy present an interaction design strategy aimed to reduce bears or postal mail; see http://www.ifwiki.org).

By using “children-oriented” works provide a simplified plot simple and encouraging discourse through short interactive compared to what exists in adult-oriented pieces.

Although these adaptations are accessible to young audiences, we are interested in Author Keywords looking further at how to construct enjoyable interaction Children, interactive narrative, storytelling fiction experiences. In particular, we are interested in how to appeal to young children who are learning how to read. INTRODUCTION Our approach is to design around the cognitive limitations Designing interactive narrative for children requires of young children ages 1-5 and examine the existing awareness of the cognitive abilities of young readers. There storytelling rituals at these ages. are many developmental stages necessary before children can understand narrative. Young children innately want to Informed by Vygotsky’s Zone of Proximal Development develop the ability to articulate themselves through choice [9] framework, we believe that puzzles in the existing of grammar, and construct logical sequences of events into works are too sophisticated for young children to play. a story. Socially, children learn about empathy and Children from 1 to 3 years have very short attention spans, communication through realizing that narrative delivery and are easily distracted by sensory displays. The affects people’s perception and relationships. sequentially rigorous nature of solving problems in traditional IF prose requires the ability to perform Beginning at preschool age, children engage in oral sequenced operations on abstract items, navigate a multi- storytelling and dramatic play to experiment with narrative room map, and solve puzzles in order to “win” the game. rd variation. From kindergarten to 3 grade, participant-led These tasks require focus, memory and abstraction that very storytelling activities are a part of many classrooms [6]. young children do not possess. An IF story that supports Children often change narratives to explore alternate their shortened attention span and provides quick identities, reorder narrative events, and play with time encouragement from small interactions would be better within stories as part of pretend play. Adapting and altering suited to their developmental abilities. narratives are an inherent part of how a child learns about social roles, logical thinking, and story construction. We Another aspect of storytelling ritual is the explicit inclusion observe that storytelling play is a primitive form of oral of social cooperation. Young children do not tell stories interactive narrative. alone; they tell stories to other young children or adults. Quick, short pieces of dialogue and negotiation between INTERACTIVE STORYTELLING FOR CHILDREN people are a key part of storytelling for young children. Dialogue that references familiar everyday objects can make the topics less abstract. Furthermore, supporting ELO_AI 2010: The 4th International Conference & Festival of the vocally expressive dialogue (e.g. by using sound effects, Electronic Literature Organization, June 3–6, 2010, Providence, Rhode alliteration or onomatopoeia) encourages the oral Island, USA. performance of the text.
