Participants were briefed on the broad definition of a ‘mobile device’ and were shown a small semi-random selection of sample portable devices which exemplified the main categories of Smartphone, e-dictionary, gaming and tablet devices (a Sharp WS004SH smartphone, a Bubugao 9388 e-learning device, Samsung Tablet, Nokia 6630 phone,
a Besta CD-618 e-dictionary and a Nintendo DS).
