Tangibles for toddlers learning language

Here we present LinguaBytes, a modular, tangible play-and-learning system developed to stimulate the language and communication skills of toddlers (with a developmental age between 1 and 4 years) with multiple disabilities. The typical characteristics of these children and their common learning environment call for intelligent systems that are quickly and easily adaptable, or, even better, adjust themselves proactively. Over the last two and a half years we have designed and tested such a system within LinguaBytes. In this paper we will outline starting points, indicate the opportunities of Tangible Interaction and finally give an overview of the current LinguaBytes prototype.

Designing for diversity: developing complex adaptive tangible products

Interactive products can help very young multi-handicapped children (1-4 years) develop their language and communication skills, under the condition that they are optimally tuned to the individual child. This has great consequences for design, since this kind of interactive products need to be adaptive to the childs development, possibilities, interests and needs. There are currently hardly any guidelines for designing adaptive interactive tangible products for such a heterogeneous user group. Through LinguaBytes, a three-year research project aimed at the development of an adaptive interactive toy for stimulating language and communication skills of multi-handicapped toddlers, we want to establish a theoretical framework, including guidelines and tools, for designing complex interactive products.

The development of LinguaBytes: an interactive tangible play and learning system to stimulate the language development of toddlers with multiple disabilities

Young children with multiple disabilities (e.g., both cognitive and motor disabilities) are confronted with severe limitations in language development from birth and later on. Stimulating the adult-child communication can decrease these limitations. Within LinguaBytes, a three-year research program, we try to stimulate language development by developing an interactive and adaptive play and learning environment, incorporating tangible objects and multimedia content, based on interactive storytelling and anchored instruction. The development of a product for such a heterogeneous user group presents substantial challenges. We use a Research-through-Design method, that is, an iterative process of developing subsequent experiential prototypes and then testing them in real-life settings, for example, a center for rehabilitation medicine. This article gives an outline of the development of the LinguaBytes play and learning environment from the earliest studies up to the current prototype, CLICK-IT.

Wrapping up LinguaBytes, for now

In this paper we present the final research prototype of LinguaBytes, a tangible interface aimed at stimulating the language development of non- or hardly speaking children between 1 and 4 years old. LinguaBytes was developed in a three-year Research through Design process in which five incremental prototypes were designed, built and evaluated in real-life settings. In this paper we present the original starting points of the project, describe our method and illustrate the resulting end-design using example scenarios of use. We give an overview of the most significant findings at the ten-month evaluation moment, after which we reflect on the original starting points and assess whether they hold up.

Let me actuate you

In this paper we focus on two aspects of Tangible Interaction that have our particular interest: 1) the added value of tangibility when designing interfaces for toddlers and 2) the value of actuators. Especially the latter is something that in our opinion has been under-investigated within the field of Tangible and Embedded Interaction. In this paper we will address the abovementioned topics by giving examples from the LinguaBytes project, which is aimed at developing an intelligent interactive play and learning environment for toddlers with multiple disabilities. These two aspects of Tangible Interaction have our particular interest since we see that multi-handicapped children could benefit highly from Tangible Interaction, but often lack the necessary bodily skills. Using actuators could offer these children possibilities to become more autonomous, thus enhancing their self-esteem and motivation. We feel that our work could not only benefit multi-handicapped toddlers in particular, but could also be used to design interactions that are more respectful to heterogeneous users in general.

Explorascope: stimulation of language and communicative skills of multiple handicapped children through an interactive, adaptive educational toy

Abstract Very young non- or hardly-speaking children with severe disabilities need active guidance to stimulate interaction with their environment in order to develop their communicative and linguistic skills. Augmentative and alternative communication (AAC) systems can help this process, provided that they are tuned to this specific user group. LinguaBytes is a research programme, which aims at developing an interactive and adaptive educational toy that stimulates the language and communicative skills of multiple-handicapped children with a developmental age of 1–4 years. In this article we show which guidelines we consider essential for developing this tool. We have developed several concepts based on these guidelines, of which we elucidate Explorascope (E-scope). E-scope consists of a tangible toy-like interface that is adaptable to an individual child with respect to his or her cognitive, linguistic, emotional and perceptual-motor skills. A first user test shows that E-scope is promising and useful for this user group.
