Researchers in special education are to some extent aware
about the potential of assistive technology tools in helping
children and the youth with ID [18–20]. Reference [21]
showed that the actual benefits of assistive technology may
be reduced or not apparent depending on the quality of the
software. This could be true since, first, the contents of many
software are not age appropriate. Second, many educational
software is unable to reach educational goals and is used as
a tool for mere entertainment.Third, many programs do not
promote independent learning.
There have been many efforts in developing edutainment
systems with tangible user interface (TUI) aimed at promoting
both learning and physical activities for children with ID
[22, 23]. Such systems either interact with the computer as an
input device or as both an input device and an output device.
In this section, we illustrate different types of tools that were
proposed to involve children into physical activity through
