It includes designs for a smartwatch that children could use to find books in the library. Different designs/solutions are needed for children because they are likely to use the "standard" devices incorrectly. The researchers used information from (expert) interviews as well as analysis of current products to assess the design for smaller interfaces. They came up with guidelines for the design of smaller interfaces - mobile phones, smartwatches. I know that navigation could be a challenge for smaller interfaces so I am happy that they designed the book-finding user interface and also prepared a navigation flow of the smartwatch interface. Navigation affects usability.
