This paper explores the intricate process of stakeholder classification within the intersection of law and innovative technologies, specifically focusing on video-based Active and Assisted Living (AAL) technologies. In three steps, the study introduces a stakeholder classification model based on pertinent legislation, critically evaluates existing AAL stakeholder taxonomies, and proposes a novel compound categorization. By integrating diverse perspectives, this approach aims to surmount the limitations inherent in current categorizations, providing a comprehensive understanding of AAL stakeholders. The findings significantly contribute to the nuanced comprehension of stakeholder identification, shedding light on the rights, obligations, and intricate interrelationships governed by legal frameworks in the domain of AAL technologies. Consequently, this research enriches our knowledge of the intricate nature of stakeholders in the digital world.
