“…Finally, other more niche sensors are becoming increasingly available. Such sensors include devices that monitor parameters of the ambient environment (e.g., air quality, noise) (Ma, Rao, Kwan, & Chai, 2020;Schnell, Cohen, Mandelmilch, & Potchter, 2021 in this special issue; Zhang, Zhou, Kwan, Su, & Lu, 2020) and more unique physiological sensors such as mobile electroencephalograms to capture brain activity data while moving through a city (Aspinall, Mavros, Coyne, & Roe, 2015;Lin et al, 2020;Mavros, Austwick, & Smith, 2016). These types of sensors are not likely to be adopted by the masses, but they are becoming increasingly more affordable and more user-friendly, which makes their implementation in research more feasible.…”
