“…For example, airline companies like Virgin Atlantic and Singapore Airlines use dynamic ambient light in an attempt to influence passengers' moods (Holland, 2011), and the CitizenM hotel in Amsterdam provides their guests with an ambient controller to personalise their room's lighting, temperature, curtain and soundtrack settings according to their mood (Figure 1b;Mood-Pad;Philips, 2008). a -Influence mood (Van de Garde, 2014) b -Mood ambiance (Philips, 2008) c -Capture mood (Alonso et al, 2008) d -Express mood (Stylios & Yang 2013) Many mood-inspired design explorations utilize some form of real-time mood measurement, either via sensors that measure (psycho-) physiological signals with wearable devices like wristbands or rings, or through behavioural expressions, such as body posture, mouse movements, or hand movement when using a pen ( Figure 1c; Alonso et al, 2008). Using digital technology, such dynamic mood data is transformed into meaningful expressions; examples include coloured light in garments ( Figure 1d; MoodWear; Stylios & Yang 2013), and dynamic surface textures in interior architecture (Textile Mirror, Davis et al, 2013).…”
