In the introductory section of the survey, issues such as degree of smartphone usage, familiarity with IoT and interest in IoT applications were evaluated. More than seventy-five percent (75%) of surveyed citizens use his/her smartphone as his/her primary mobile phone and more than sixty percent (60%) are at least moderately familiar with IoT.
The following graph shows the ranking of all the IoT applications. The top five (applications with more than forty percent (40%) in green colour) consists of consumption sensors (77%), presence sensors (46%), public transport measuring (44%), traffic monitoring (43%) and Monitor an aging family member (41%). Whereas the least interesting IoT applications resulted to be hydrometers (11%) and infant monitor (9%), respectively.
Going into the analysis of the section of the survey dedicated to ‘ClouT field trials’ we can see how all of the developed field trials have resulted at least moderately interesting for more than fifty percent (50%) of the surveyed citizens. The ranking of the field trials is: Genova field trial (65%), Fujisawa field trials (60% in both), Santander field trial (55%) and Mitaka field trial (almost 50%).
One point to be remarked in relation with this question is the percentage of no answers, not completed or not displayed categories, around thirty percent (30%). It may be due to several factors in relation with surveyed citizens, such as, lack of awareness in the field trial, an incomplete or non attractive description of the field trial, lack of time to complete the survey.
As previously mentioned, a more detailed analysis of the replies related to the Pace of the City application was made. The first point of this analysis is in relation with the different kinds of events included in the Pace of the City (PoC). The following graph shows the ranking of these events. The blue colour represents positive answers gathering “moderately”, “quite” and “very much” answers. The red colour represents negative answers, gathering “not at all” and “not so much” answers. As can be seen, the top five (events with more than 90%) consists of: Culture (100%), Traffic (95%), Transport (91%), Health (91%) and Water (90%). The least interesting event is Sport, although its interest percentage is higher than sixty percent (60%).
As it happened in the case of level of interest for the provision of the five field trials, about thirty percent of surveyed citizens did not answer/complete these questions.
The second evaluation point was the first experience using the Pace of the City (PoC), which results are shown in the next figure. As in the PoC events case, blue colour represents positive answers, while red colour represents negative answers. As it can be seen, more than sixty seven percent (67%) of surveyed citizens reported a good first experience: happy, exciting, wide-awake and satisfying experience, while less than thirty percent (30%) of surveyed citizens reported bad experience. It is important to remark that in this case, no answered/completed/displayed category shows a high value, more than fifty-seven percent (57%) of citizens did not answer, nor complete this question.
Finally, the last evaluated issue is PoC service, where parameters such as flexibility, compatibility, usefulness have been taken into account. The following graph shows the results obtained.
As it can be seen, the top five (issues with more than seventy-seven percent (77%)) are IT Experimentation (96%), Recommendation (91%), Future Use (87%), Flexibility (85%) and compatibility (77%). The worst evaluation is for Easy service (33%) and Usefulness (32%). As in the previous case, no answered/completed/displayed category shows a high value, more than fifty-seven percent (57%) of citizens did not answer, nor complete this question.
Demographic information such as gender, age, studies level and interest field of citizens were included in the last section of the survey. As in the previous case, no answered/completed/displayed category shows a high value, almost forty percent (40%) of citizens did not answer, nor complete this set of questions.
The percentage of male and female citizens who have participated in the survey is around thirty percent (30%) in both cases. The interest in this kind of services/applications does not depend on the gender.
The range of age with a more active participation has been from thirty-five to forty-four years old (33%), followed by the range between forty-five to fifty-four (10%) and older than fifty-five (10%).
Citizens with higher educational level have participated more actively (about 50%) than those with lower studies level (about 11%).
In relation with field of study, citizens related to computer science have been the most participative (about 9%), followed by business (6%) and economics (6%). Others graduates such as architects, physicist and telecommunication engineer have also answered the survey (2%per each).
