PAGE, T., 2013. Usability of text input interfaces in smartphones. Journal of Design Research, in press, 11 (1), pp. 39 - 56.
This paper reviews a number of different text input methods on
smartphones and proposes how smartphone typing methods may inhibit user
interaction rather than enhance it. It explores design and ergonomic
considerations underpinning the use of six commonly used smartphone text
input methods in order to determine and compare their usability. Furthermore,
it discusses the results from testing smartphone users to assess which method is
considered most efficient. It concludes that alternative input methods such as
Swype and SwiftKey offer substantial benefits to users and are comparable
with common typing speeds found on computer keyboards.
