Ever since the Swiss Army knife, fusion technology has scaled new worlds of usefulness, from the floating BBQ grill to the mp3 player/breathalizer.

Students were asked to answer an anonymous quantitative questionnaire (on a 5-level Likert scale) about the degree of usefulness they found with the different active learning methods used.
The scale includes the construct of usefulness, which represents "the degree to which a person believes that using a particular system would enhance his or her job performance" [ 21]; and ease of use, which represents "the degree to which a person believes that using a particular system would be free of effort" [ 21].
Consumers used a Global Perceived Impression of Usefulness (GPIU) scale to rate usefulness of the mSTEPs, scored with an 11-point NRS scale, 0 indicating 'not at all useful' to 10 indicating 'extremely useful' [ 46].
Subjects rated the usability on the perceived-of-usefulness and perceived-ease-of-use scale [16] after each scenario.
On a 1 (very good) to 6 (insufficient) scale, the usefulness of the performance reports was rated 3.67 (±1.40).
