Abstract

[Autom. eng. transl.] Introduction: The term "home automation" refers to interdisciplinary science which, through the integration of computer science, engineering and analysis of the User Experience, studies how to improve the quality of life of people within living environments. Home automation science is associated with the adjective "intelligent", referring to its technological capabilities to satisfy and facilitate, with a certain degree of autonomy, those who live in the environment. Some advantages of automation are: flexibility, that is, the possibility of changing the system configuration even after installation is complete and multifunctionality, that is, the ability to perform multiple functions by a device. Up to now few studies have focused on the experience of the person within these new complex environments using neuroscientific investigation methods. Therefore the present study aims to investigate the impact of home automation technology on the person by detecting the cortical oscillations (EEG) and peripheral responses (biofeedback) of the user while exploring the home automation environment in real time. Materials and methods: The experiment took place in a home automation showloft, set up in a showroom of a sector company. 19 healthy participants (12 females and 7 males; Half = 25.05; DS age = 3.05) explored the areas of the home automation showloft (tech-areas: entrance, kitchen, living room, bathroom and bedroom), interacted with the environment and have observed its intelligent responses. During the trial, users' cortical activity and autonomic indices were detected with an initial baseline lasting 120 seconds. For the electroencephalographic (EEG) recording, a 15-channel system with dry electrodes positioned on Fp1, Fp2, F3, Fz, F4, T7, T8, C3, Cz, C4, P3, Pz, P4, O1, O2 was used . The EEG data were analyzed according to the frequency domain and the following bands were extracted: delta (0.5–4 Hz), theta (4–8 Hz), alpha (8–12 Hz) and beta (14–20 Hz) . During the analysis of EEG data, the electrodes were grouped into the following regions of interest: frontal, temporomacral and parieto-occipital. A biofeedback device was used to detect the following autonomic indices: Heart Rate (HR), Skin Conductance Level (SCL), Skin Conductance Response (SCR), Pulse Volume Amplitude (PVA) and Blood Volume Pulse (BVP). Results: As regards cortical oscillations, there was a greater presence of the alpha band (less activation) during the baseline compared to the exploration phase of the other home automation areas. Specifically, the "bathroom" tech-area turns out to be the area where the least alpha is present. At the peripheral level, a significant difference emerges between the basic conditions and the “bedroom” tech-area in terms of heart rate. Furthermore, for PVA a significant difference between the baseline condition and all the other tech-areas was detected. Discussion: These preliminary results suggest that the home automation environment proves to be an environment that activates the user both centrally and peripherally. Specifically, for the more sensorial interactive areas ("bathroom" and "bedroom") there is a greater activation at the cortical and cardiovascular level which can be interpreted as an increase in the level of engagement both cognitive and emotional by part of the subject.
