Application of nudge in the development of Human-Computer Interfaces in Smart Cities – A Systematic Review of the Literature

Abstract

Behavioral sciences have proven effective in promoting behavioral changes in various contexts. With the advancement of digitalization and the constant use of devices connected to the Internet, an opportunity arises to apply these techniques to the human-computer interface (HCI). This study aims to analyze the application of nudges in HCI, seeking to replicate the positive results observed in the real world. For this reason, a review of international scientific literature was carried out in the Scopus and Web of Science databases in two stages: a bibliometric analysis followed by a systematic review. 34 articles were identified that prove the effectiveness of using nudges not developed by HCI, resulting in positive impacts similar to those obtained in offline contexts. Nudge-based interfaces promote the integration of users with different profiles and skill levels in using digital systems. Furthermore, the integration between nudges, artificial intelligence (AI) and HCI enhances managers' decision-making, in addition to encouraging safer and more sustainable behaviors through precise, intuitive and accessible interventions.
