Computer vision-based and WiFi-enabled smart cities technologies can be the most informative, but since theycapture users’ personal information they may elicit public opposition. Conversely, PIR sensorsare anonymous and privacy-preserving (Akhter et al., 2019). The choice of using PIR sensors forour project provides students two takeaways: !1) users’ perception is an important considerationfor engineers, and (2) the “best” solution is not always the most suitable solution. Moreover,when designing their data acquisition module, students also had to account for

There are several tests that have been applied to measure spatial visualization skills of students[1, 2], and there are numerous studies that have collected and analyzed information regardingdemographics, spatial visualization skills, and academic performance [3, 4]. Of interest are studieswhere spatial visualization skills have been linked to abilities to do engineering and technologywork, and subsequent studies that have provided a relationship between those skills by studentsand their performance in engineering courses or programs, particularly for engineering graphicsand design courses [5].

The competency-based model provides an opportunity for educators tointroduce projects to students at an early stage in their careers in an effort to help them develop apassion for a particular field. These projects can also help students make early choices anddecisions about their future career aspirations.

The top four surveyed as being available to AE studentsare engineering software (88%), high-end computers (64.7%), and video conferencing equipmentand plotters (tied at 58.8%). The interesting result here is that the plotter as printed media is justone form of communication, whereas software is needed to complete the technical work.
