Briefing projetual em design de interiores residenciais: o uso de ferramentas digitais na personalização de ambientes.

Abstract

Contemporary interior design has increasingly embraced user-centered design approaches in response to the growing emphasis on personalized residential environments and the incorporation of digital technologies into the design process. In this context, the project brief plays a strategic role as an instrument for consolidating information that, once gathered, analyzed, and systematized, informs spatial, aesthetic, and experiential decisions. This study examined the contribution of digital tools for data collection, visual curation, and artificial intelligence-mediated systematization to the development of the project brief in residential interior design and to the personalization of inhabited space. The study adopted a qualitative, interpretivist approach and was conducted as a single-case study in an academic setting. The empirical case consisted of a hands-on workshop involving interior design students and a representative user, focused on the design of a residential bedroom. The activity encompassed the gathering, analysis, interpretation, and systematization of user information to produce the Structured Synthesis of the Project Brief, with the support of artificial intelligence. Based on this document, the students developed a design proposal, which was presented to the user for validation. The procedures included a structured questionnaire, a preference board, a style test, direct observation, and audiovisual records. Data were analyzed through evidence triangulation, content analysis, and compositional image analysis. The results indicate that digital tools and artificial intelligence improved the organization and explicit articulation of user information during the initial phase of the project, lending greater stability to the functional and spatial definitions of the environment. Decisions concerning atmosphere, color composition, and perceptual experience, however, remained dependent on human interpretation by the user and students throughout the process. The findings indicate that artificial intelligence contributes to systematizing the information used in design conception but does not replace human mediation in consolidating spatial decisions, since such consolidation depends on the situated experience of inhabiting space. The project brief thus emerges as a flexible, non-linear instrument in which technology organizes the more stable layers of information, while human interpretation accounts for the perceptual and symbolic dimensions that underpinned personalization in the context investigated.
