Today, it is the global challenges that play an important role for economic and political work. Especially sustainability has become a widely recognized topic raising global alliances, which develop frameworks such as the Sustainable Development Goals (SDGs) established by the United Nations. When it comes to production and consumption, they emphasize that more sustainable products and services must be designed. In the field of, mostly digital, product development one well‐known approach promoted over the last years is the human‐centered design (HCD) process. In this paper, we aimed at bringing together both, sustainability efforts and human‐centered product development by integrating a specific SDG and related targets into HCD activities. To illustrate our approach, we used a fictive example to demonstrate what kind of practical implications this integration brings to light. The proposed outline shows that on a theoretical level it is possible to follow a specific target through the HCD process and could therefore be a practical asset to all designers' daily work. Further projects with industrial partners will show the practicability for the daily context and potential needs for adapted as well as new methods and process steps. In addition to practical implementation, we identified several research questions for the field of Sustainable Human‐Computer Interaction (SHCI), e.g., concerning the connection between rebound effects and the HCD process.

From an economic perspective, Artificial Intelligence Systems are built to increase efficiency, productivity and reliability. Assistance systems like voice assistants (VAs) are one example of this kind of interactive technology; yet based on the Intelligence Augmentation approach, they ought to primarily support the users' capabilities and allow them to act with self‐determination. Nevertheless, those systems are usually perceived as a black box. Thus, on the one hand, VAs can be seen simply as a tool for fulfilling a task, although on the other hand, the conversational interaction raises expectations and needs for humanlike interactions. According to the international norm ISO 9241‐11, a usable system is one that can be used to achieve specified goals with effectiveness, efficiency and satisfaction. We use this definition of usability to delineate a framework for the design and evaluation of VAs. We posit that certain human values like trust and well‐being are crucial for a satisfying user experience with VAs. Specifically, the system ought to prevent frustration of psychological human needs in order to ensure the users' self‐determination — for practicing design and evaluation of VAs in a wholesome manner. Our aim is to provide guidelines that move the development of VAs towards enhanced usability and human centeredness. Considering each usability component, we discuss how to fulfill context‐based user needs and requirements in order to ensure effectiveness of the VA interaction. To address the efficiency and satisfaction components, we develop evaluation guidelines for VAs based on the interaction principles according to ISO 9241‐110 and current literature.
