“…Although we live in highly diffuse and "vivid" multisensory environments, and despite the growing interest from different application domains, most studies on human emotional responses to environmental characteristics still focus on a number of well-defined and restricted sensory aspects of the environment (typically under highly controlled conditions). As a result, we still lack systematic knowledge about successful multisensory interventions that elicit desirable outcomes (Barrett, Barrett, & Davies, 2013;Gerdes, Wieser, & Alpers, 2014;Jain & Bagdare, 2011;Oakes & North, 2008;Spence, Puccinelli, Grewal, & Roggeveen, 2014;Turley & Milliman, 2000). Environmental characteristics such as luminosity of light sources, the nature and level of ambient noise and acoustics, the presence of specific odors, color hues and shades, and materials and atmospheric factors such as temperature and humidity, all generate sensory input, and combined contribute to specific reactions in the observer (Biggers & Pryer, 1982;Franz, 2006).…”
