Abstract
The Shadow Box is a tangible computing project
that exploits visual association and auditory clues to
teach children the representational relationship between
words and their meanings. The Shadow Box contains
three major components: the main box, picture blocks
and word blocks. The Shadow Box activates when a
block or a matching pair of blocks is placed inside. The
box prompts children to find matching blocks and
combine them together. When children successfully
combine the right word and picture, the box rewards
them with an animated video as if they had made the
objects come alive. An informal study shows that
children responded positively to the concept of the box.
They played with it for a length of time and engaged in a
collaborative learning process with other children.
1. Introduction
Learning is effective when children build new
understandings based on active reconstruction of
existing knowledge and preconceptions. During the
development of literacy skills at an early age, children
may experience difficulties learning to read and write if
they don’t have a preconception of language’s
representational nature. The National Research Council
(1999) suggests that young children should learn
representational systems during their early literacy
development [2]. Children acquire many of the skills
necessary to attain literacy prior to the stage of reading-
readiness which are also known as pre-reading skills.
The acquisition of these skills provides the conceptual
framework necessary to achieve higher level skills such
as onset recognition fluency (beginning sounds), letter
recognition fluency, phonemic segmentation, and
ultimately, phonemic awareness, which links directly to
reading mastery [5]. The acquisition of such skills is
hierarchical, with children generally mastering word-
level skills before they master syllable-level skills,
syllable-level skills before onset-rime skills, and onset-
rime-level skills before phoneme-level skills. This
project focuses on helping preschool aged children attain
word-level skills. We propose a tangible toy for early
literacy development called the “Shadow Box”. The
Shadow Box aims to teach the representational nature of
written language to three to four year-old children while
they are playing with tangible word and object blocks.
The Shadow Box consists of three primary components:
the shadow box equipped with an RFID reader, as well
as picture blocks and word blocks with embedded RFID
tags. In order to activate the Shadow Box, a single block
or a matching pair of blocks must be placed inside. If the
child inserts a word block, the box pronounces and
spells the word and prompts the child to look for its
matching picture by projecting a static shadow image of
the object. A similar sequence is initiated when the child
inserts a picture object and is prompted to find the
matching word block. When the child successfully
matches a picture block with its corresponding word
block and places the pair inside the Shadow Box, they
are rewarded with an animated movie clip.

Even though computers permit the creation of
dynamic content and the development of sophisticated
interactive systems, it is still difficult to engage children
in realistic settings using screen-based computational
media [1]. Conventional computers do not support
concurrent interaction and physical exploratory
experience which is most familiar to preschool children.
To overcome this limitation, many researchers are
interested in how tangible technology can help the
