32: A Spatial Framework For Human Control In Shared Intelligent Environments

The field of intelligent and interactive environments is vast but fragmented, often lacking a cohesive perspective to evaluate and improve existing systems. Especially in shared environments, conflicting needs and insufficient interaction mechanisms often lead to reduced usability and limited user engagement. This paper proposes a new classification framework by analyzing two key components of interaction: interfaces, which mediate communication between users and digital systems; and actuators, which enact physical change in space. These elements are overlaid to create a classification framework of collective interaction in shared environments. Each category is illustrated through existing and conceptual examples, and discussed in terms of its architectural impact, social negotiation, and automation levels. Instead of ranking systems, the framework underlines the importance of an architectural, human-centered approach that prioritizes spatial experience and collective interaction as key components. It offers a new perspective not only to understand existing examples but also to guide future designs.
