A Living Room | ScienceGate

AbstractHuman–computer interaction (HCI) is particularly interesting because full-immersive technology may be approached differently by users, depending on the complexity of the interaction, users’ personality traits, and their motivational systems inclination. Therefore, this study investigated the relationship between psychological factors and attention towards specific tech-interactions in a smart home system (SHS). The relation between personal psychological traits and eye-tracking metrics is investigated through self-report measures [locus of control (LoC), user experience (UX), behavioral inhibition system (BIS) and behavioral activation system (BAS)] and a wearable and wireless near-infrared illumination based eye-tracking system applied to an Italian sample (n = 19). Participants were asked to activate and interact with five different tech-interaction areas with different levels of complexity (entrance, kitchen, living room, bathroom, and bedroom) in a smart home system (SHS), while their eye-gaze behavior was recorded. Data showed significant differences between a simpler interaction (entrance) and a more complex one (living room), in terms of number of fixation. Moreover, slower time to first fixation in a multifaceted interaction (bathroom), compared to simpler ones (kitchen and living room) was found. Additionally, in two interaction conditions (living room and bathroom), negative correlations were found between external LoC and fixation count, and between BAS reward responsiveness scores and fixation duration. Findings led to the identification of a two-way process, where both the complexity of the tech-interaction and subjects’ personality traits are important impacting factors on the user’s visual exploration behavior. This research contributes to understand the user responsiveness adding first insights that may help to create more human-centered technology.

The global average air temperature is increasing as a manifestation of climate change and more intense and frequent heatwaves are expected to be associated with this rise worldwide, including northern Europe. Summertime indoor conditions in residential buildings and the health of occupants are influenced by climate change, particularly if no mechanical cooling is used. The energy use of buildings contributes to climate change through greenhouse gas emissions. It is, therefore, necessary to analyze the effects of climate change on the overheating risk and energy demand of residential buildings and to assess the efficiency of various measures to alleviate the overheating. In this study, simulations of dynamic energy and indoor conditions in a new and an old apartment building are performed using two climate scenarios for southern Finland, one for average and the other for extreme weather conditions in 2050. The evaluated measures against overheating included orientations, blinds, site shading, window properties, openable windows, the split cooling unit, and the ventilation cooling and ventilation boost. In both buildings, the overheating risk is high in the current and projected future average climate and, in particular, during exceptionally hot summers. The indoor conditions are occasionally even injurious for the health of occupants. The openable windows and ventilation cooling with ventilation boost were effective in improving the indoor conditions, during both current and future average and extreme weather conditions. However, the split cooling unit installed in the living room was the only studied solution able to completely prevent overheating in all the spaces with a fairly small amount of extra energy usage.

Housing Standards

Abstract Introduction In recent years, Public Health devoted a growing interest to housing conditions. In particular, housing dimensions and functional characteristics are relevant, mainly considering population ageing and disability. Aim of the study is to compare housing standards of some European countries to analyse their ability to satisfy new population needs. Methodology The dwellings dimensional standards of 9 European countries (Sweden, UK, Denmark, The Netherlands, France, Germany, Portugal, Spain and Italy) are compared. From the websites of the official channels of the various countries the regulations have been downloaded. The standards have been compared. Results A wide variability in the dimensions of room among the standards is observed (e.g. single room: from 9 sqm in Italy, to 7 sqm in France, to the absence of any limit in UK, Germany - Hesse and Denmark). Italian and French regulations define housing dimension considering the room use (eg. bed or living room) and the number of people. The Swedish regulation provides performance requirements and functional indications but does not specify the minimum dimensions of habitable rooms. The rooms' minimum height varies between the standards. In Italy and Portugal, the minimum height of the ceiling is intended to be 2.70 m, while in the other nations the minimum heights vary from 2.60 m in the Netherlands to no limit in UK. Conclusions A diverse approach among European Countries is observed: from a market-oriented logic (e.g., UK), in which minimum dimensions are not defined, to a prescriptive one (Italy), to a functionality-oriented (the Netherlands). The regulations of some Countries are health-oriented especially for most fragile social classes, since, defining larger dimensional standard, they reduce the risk of overcrowding, indoor air pollution and mental distress. However, considering the health, social, environmental and economic trends, many of these standards should be revised. Key messages Optimal housing standards promote the health and well-being of occupants. Healthy housing, healthy people.
