# Smart Interactive Technologies in the Human-Centric Factory 5.0: A Survey
## 3 Discussion and Conclusions
In this regard, wearable devices that boost cognitive and operational capacities are increasingly being utilized and improved in manufacturing industries [107]. Exoskeletons, i.e., augmenter equipment that give extra strength and physical capabilities to protect the operator from the adverse effects of heavy workloads [93], are a case in point. According to [PERSON] et al. [108], virtual technologies such as smart AR glasses, spatial AR projectors, etc., are viable and novel gadgets that facilitate flexible operations and technical guidance through information transmission and virtualization. Moreover, wearables could open new channels for alerting workers and their general practitioners about critical health conditions, both physical and mental, as well as supporting workers in adopting healthy behaviors in the workplace [3]. However, these improvements in working conditions cannot be conducted at the expense of workers' fundamental rights of privacy, security, autonomy, and human dignity. According to our vision, it is essential that future HCI and HCAI specialists become aware of the potential ethical issues of smart interactive technologies, also considering the smart factory context and the new, central role of workers, see for more details [PERSON] et al. [107]. **Sustainability. ** Another relevant Industry 5.0 concept, also emphasized in the 2021 European Commission's report [3] and highlighted in Section 2.5.2, is the one of environmental sustainability. According to [PERSON] et al. [103] Industry 5.0 _\"recognizes the capacity of industry to fulfill social objectives beyond employment and development, to become a sustainable source of development, by making production regard the limitations of our planet and prioritizing employee health first\"_. Sustainability is closely related also to the promotion of a circular economy, i.e., the idea of developing circular processes that reuse, repurpose, and recycle natural resources, reducing waste and environmental impact [3]. One of the enabling technologies for reaching sustainability goals is certainly IoT. Drawing from the IoT Guidelines for Sustainability produced by the World Economic Forum ([[https://www.weforum.org/](https://www.weforum.org/)]([https://www.weforum.org/](https://www.weforum.org/)), accessed on 29 July 2022) [109], we recall a set of points which specifically refer to the sustainability and impact measurement area. Firstly, along with all the valuable data they may collect with IoT systems, smart factories should make sure to measure and process energy usage data, so as to minimize costs, increase savings, and reduce waste (_consumption_). Then, smart factories should embrace a sustainability awareness culture to respond to new generational demand, enhancing brand reputation and attracting top talent (_culture_). Furthermore, potential impact should be evaluated and results measured based on some ad hoc framework, such as the United Nations Sustainable Development Goals ([[https://sdgs.un.org/goals](https://sdgs.un.org/goals)]([https://sdgs.un.org/goals](https://sdgs.un.org/goals)), accessed on 29 July 2022) (_impact_). When planning an Internet of Things project, potentially addressable sustainable development goals and targets should be identified and incorporated into the commercial design (_goals_). Finally, RFID or GPS sensors monitoring should be implemented both to track products in the delivery process and to track inventory items within the warehouse and the production lines (_monitoring_). **Further challenges. ** Along with all the enhancements and improvements brought by the Industry 4.0 and 5.0 to production processes and to the workers' performances, unavoidably there come new risks for both individuals and organizations that can directly affect productivity and translate into financial risks. [PERSON] [110] gave an overview of the technical components of a smart factory, raising the awareness of this manufacturing trend in terms of risks evaluation.
