ENEL METERS USABILITY
Supervisor: Anna Spagnolli
Graduate student: Daniel Kerrigan
– to find out if the information that the meter presents is understood by the users
– what prevents the users from successfully completing the task
– the users opinion and the overall evaluation of the meter
After the completion of the tasks a satisfaction questionnaire adapted from the Microsoft Desiderability Toolkit was administered to the participants with the aim of investigating the user’s opinion on the meter. A post structured interview was conducted on the answers from the satisfaction questionnaire in order to explore more in depth the motivation and opinions of the participants on selecting their answers. The tasks and the interviews were video recorded and the participants behaviors and verbalizations were coded and analyzed with the software Noldus the Observer.
