Background: Because the fulfillment of basic/fundamental psychological needs affects people’s motivation and well-being, measuring the degree to which these needs are met is of interest to researchers across various domains. Although numerous self-assessment tools have been developed, no recent comprehensive reviews exist, hindering cumulative scientific progress. The present systematic review aimed to identify and analyze the main approaches to developing self-report scales for assessing basic/fundamental psychological need fulfillment. The objective is to inform readers interested in selecting instruments for their studies and those intending to develop new scales.

Methods: Following PRISMA, we conducted a search of Scopus, Web of Science, PubMed, and ProQuest in August 2023. The following information was extracted from eligible studies: Scale name, abbreviation, theoretical basis, application domain, final scale construction, scale development and validation methodology, and citation count.

Results: Our search identified 32 primary studies, in which 31 original scales were developed and validated, and 89 secondary studies that aimed to modify these original scales. The predominant theoretical basis was Self-Determination Theory, although eight scales were based on alternative need typologies. The scales were either domain-general or specific to contexts such as work, education, or exercise/sports contexts. While most were designed to measure need satisfaction, some also addressed need support, frustration, and thwarting.

Conclusion: Despite significant efforts in developing, adapting, and applying scales to measure need fulfillment, we found several issues resulting from diverse perspectives on conceptualizing psychological needs and need typologies, discordant approaches in developing and validating measures, and other inconsistencies that should be acknowledged and addressed in future research.@en

Addressing sustainability challenges requires shifts in consumption patterns and lifestyles. Design for Sustainable Behavior (DfSB) aims to cultivate sustainable attitudes and behaviors through product-based interventions. However, there can be a disconnect between design strategy and its embodiment and sometimes conflicts between designers’ intent and users’ interpretation. This paper explores the role of metaphors in DfSB in terms of using metaphorical thinking during the design process and/or creating product metaphors in the final design. It begins by identifying barriers that prevent people from engaging in sustainable practices, such as human nature and ambiguity in design. It then examines the roles of metaphor in design and its key strengths in DfSB. Furthermore, the paper outlines three methods to generate metaphors in DfSB: (1) The source domain implies the target domain. (2) The source domain serves design goals and strategies. (3) Cross-domain mapping is based on embodied experience. In conclusion, the paper discusses potential issues surrounding its use in DfSB.@en

The relevance of human needs is generally recognized in human-centered design research and practice. However, a challenge of working with needs is that the word “need” can be interpreted in various ways, which can hinder effective communication and collaboration. Need typologies, in such cases, can serve as a shared language by providing an overview of distinct human needs. Building on a design-focused typology of thirteen fundamental needs, this paper introduces a detailed version in which two complementary but distinct facets explain each need. We envision this fine-grained vocabulary of basic human needs can support initiatives in human-centered design research and practice, particularly facilitating and enriching conversations among people from different backgrounds. Furthermore, we propose three directions for future research on this topic.@en

nergy consumption of the EU has a crucial environmental impact; several efforts are nowadays thus directed into massively reducing energy consumption by envelope improvement, system efficiency and smart control. On the other hand, the indoor thermal and lighting conditions significantly influence users' wellbeing and productivity, which is especially important when dealing with educational and working facilities. Strategies to enhance system efficiency are focused on design and construction aspects. These strategies ease to promote a powerful approach which is needed when focusing on existing buildings in need of retrofit measures. When dealing with new or refurbished buildings, energy saving has a further step to achieve. In the last years, research trends moved towards an increasing inclusion of human factors in energy evaluation. This allows to account for the occupancy variability in the energy analyses, considering how to bridge the performance gap between predictive models and actual consumptions due to indoor thermal settings. In empty buildings energy consumption is huge and economic efforts are wasted, due to unconscious energy-wasting behaviors. Previous studies with Interactive Virtual Environments confirmed that indoor environments illuminated by different color lights lead to the perception of different levels of thermal comfort. The results of the present paper replicate previous evidence collected in real conditions, suggesting that Virtual Reality is a valid and reliable tool to assess thermal comfort more quickly and cheaply. This paper provides a further perspective on this topic, including also the use of different fragrances to understand how the indoor environment could be enhanced and manipulated to increase wellbeing, thermal perception and finally energy saving. @en

Starting from the pro-environmental potential of virtual reality (VR), the aim was to understand how different statistical information formats can enhance VR persuasive potential for plastic consumption, recycling and waste. Naturalistic, immersive virtual reality environments (VREs) were designed ad hoc to display three kinds of statistical evidence formats, featured as three different formats (i.e., numerical, concrete and mixed). Participants were exposed only to one of the three formats in VR, and their affect, emotions, sense of presence, general attitudes toward the environment, specific attitudes and behavioral intentions toward plastic, use, waste, recycle, as well as their social desirability proneness were measured. Numerical format was the least effective across all dimensions. Concrete and mixed formats were similar. Social desirability only partially affected participants’ attitudes and behavioral intentions. Numerical format did not increase the persuasive efficacy of statistical evidence displayed in VR, with respect to visual alone. Implications and future directions for designing effective VRE promoting pro-environmental behaviors were discussed.

Within the scope of Design for Sustainable Behaviour, the connection between behavioural change strategies and design idea generation has received limited attention. This paper highlights metaphorical thinking in product design to stimulate sustainable behaviour. In particular, the current study proposes a metaphor-based design method to guide designers on how to associate product features with behavioural and experiential cues through metaphors. We next report two design cases to evaluate this method. In the end, the shortcomings of current research and future developments are also discussed.@en

The scarce availability of water in highly populated cities is about to become a social problem. While the water service companies work on improving the distribution network in order to reduce losses, it is evident that one of the main problems is due to an excess of use of this resource by users. This consumption is relatively controlled when excessive consumption is clearly associated, in the consumer mind, with high costs. However, when users are in public places they tend to consume water because of a loss of correlation with costs. In this paper, we describe the design of a device to be installed in public environments, which aims to reduce the consumption of water. The device measures in real time the flow of water and sends the user visual and sound information trying to create a link between consumption and costs. The device has been installed in a university campus bathroom and has been tested. Test results show a reduction in water consumption, especially in the interactive prototype approach compared to the conventional treatment. Further modifications for future development of the interactive device is also discussed.@en

Littering is a highly diffused anti-environmental and anti-social behavior, especially among young people. Furthermore, cigarette butts are one of the most littered items and are responsible for both severe environmental damages and high clean up expenses. The aim of this project is to design an interactive ashtray for the campus environment to limit the cigarette butts littering behavior in an engaging and effective way. Qualitative and quantitative data are collected. Coded observations were implemented through the research process, including the 2 pre (without the prototype) and 2 pros (with the prototype) sessions. Also, user experience test and one to one interview were conducted for deepening the understanding of the littering phenomenon and the reasons behind in the behavior among young people. The prototype indeed reduced the number of cigarette butts littering among observed behaviors of 156 students, especially in male sample. Final results indicate the behavior change of disposers is moderated by other factors, as the environmental cleanliness. Future development is also discussed.

The use of collaborative robots in the manufacturing industry has widely spread in the last decade. In order to be efficient, the human-robot collaboration needs to be properly designed by also taking into account the operator’s psychophysiological reactions. Virtual Reality can be used as a tool to simulate human-robot collaboration in a safe and cheap way. Here, we present a virtual collaborative platform in which the human operator and a simulated robot coordinate their actions to accomplish a simple assembly task. In this study, the robot moved slowly or more quickly in order to assess the effect of its velocity on the human's responses. Ten participants tested this application by using an Oculus Rift head-mounted display; ARTracking cameras and a Kinect system were used to track the operator's right arm movements and hand gestures respectively. Performance, user experience, and physiological responses were recorded. The results showed that while humans’ performances and evaluations varied as a function of the robot’s velocity, no differences were found in the physiological responses. Taken together, these data highlight the relevance of the kinematic aspects of robot’s motion within a human-robot collaboration and provide valuable insights to further develop our virtual human-machine interactive platform.

The built environment has a great responsibility for energy consumption and carbon emissions worldwide. Thus, energy conservation in building plays a vital role in sustainable economic growth. Researchers from many disciplines have devoted to the field of design for energy-efficient buildings. However, human factors, as the way people interact or use the designed environment, are also fundamental. In particular, colour-temperature perceptual associations might be used to influence people’s thermal experiences. In this study, we presented two national groups of participants with four rooms in Virtual Reality (VR) to test the effect of coloured ambient light on the perceived thermal comfort, context of use and ambient atmosphere. The results showed that room-lighting could affect the thermal comfort perceived and its advantage for energy conservation. Detailed analyses and future developments are also discussed.@en

With the advance of technology, radical innovation plays an increasing essential role in gaining competitive advantages by leveraging the brandy new technologies such as internet of things (IoT) in product or services innovations. Although its importance is widely recognized, the mechanism of radical innovation is still poorly understood due to high level of uncertainty about its prospects. This paper aims to evaluate the radicality of design ideas from their technological changes that are the obvious and measurable characteristics of radical innovation at very beginning of their developments. To do so, a radicality evaluation method is formulated after a systematic review of studies on radical innovation and integrating of ideas evaluations methods in relevant domains. Afterwards, two radicality computing formulas are regressed through a statistical analysis of known design cases. The feasibility of the formulas is verified by a serial of recognized radical innovations followed by a case study that is related to additive manufacturing. Its application in new product development is demonstrated by a design project of adhering devices. The proposed method has potential to fertilize studies on radical innovation and knowledge-based innovation.

Road accidents represent the primary cause of death among young drivers. To understand the emerging issue of young drivers’ involvement in traffic accidents abroad, risk-taking behaviors were investigated in familiar and unfamiliar driving situations. Twenty-two young Chinese drivers completed a road regulation test followed by a simulated test drive. The number of traffic violations and accidents in familiar and unfamiliar driving intersections were correlated to road regulation knowledge, risk perception scores and to self-assessment of driving skills. Significant number of mistakes was found in risk-taking situations, regardless of the familiarity of the situation, especially for drivers that presented high ratings of self-assessed driving skills. Results show that risk-taking behaviors while driving in unfamiliar conditions are mediated by psychological factors, like self-assessment of being a good driver, more than the actual knowledge of road regulation rules. Implications for international driving can be considered for future research development.
