Abstract:
|
Ubiquitous and pervasive computing is fundamentally
transforming product categories such as music, movies, and books
and the associated practices of product searching, ordering, and
buying. This paper contributes to theory and practice of digital
payments by conducting a design science inquiry into the mobile
phone wallet (m-wallet). Four different user groups, including
young teenagers, young adults, mothers and businessmen, have
been involved in the process of identifying, developing and
evaluating functional and design properties of m-wallets.
Interviews and formative usability evaluations provided data for
the construction of a conceptual model in the form of sketches
followed by a functional model in the form of low-fidelity mockups.
During the design phases, knowledge was gained on what
properties the users would like the m-wallet to embody. The
identified properties have been clustered as ‘Functional
properties’ and ‘Design properties’, which are theoretical
contributions to the on-going research on m-wallets. One of the
findings from our design science inquiry into m-wallets is that
everyday life contexts require that evaluation criteria have to be
expanded beyond “functionality, completeness, consistency,
accuracy, performance, reliability, usability, fit with the
organization, and other relevant quality attributes” [12] that are
used within current design science work. |
