This research aims to provide an analytical comparison between the use of generative artificial intelligence (AI) tools and human-centered design (HCD) methods in implementing smart home components within a residential interior space. The research adopted a descriptive, analytical, and comparative approach, through a case study of a living room connected to a residential entrance. The room was designed using two methods: the first relied on human-centered design using AutoCAD and ds Max 3 software, while the second employed generative AI tools (ChatGPT, Gemini, and Leonardo AI). The outputs were then analyzed and compared according to a set of criteria, including: accuracy in spatial relationships, integration of smart systems, level of innovation, time efficiency, and feasibility of the solutions.
The results of the study showed the superiority of human-centered design in achieving higher accuracy in spatial distribution, dimensional control, and representation of smart systems within the space. Meanwhile, generative AI tools were distinguished by their ability to produce a wide range of innovative design solutions in a short time, particularly in terms of visual representation and lighting manipulation. However, the study revealed challenges related to the phenomenon of "hallucination" resulting from deficiencies or ambiguities in the descriptive commands, and the accompanying excesses in some architectural and functional details.
This indicates that generative AI tools cannot completely replace human designers in smart home design, but rather serve as supporting tools that enhance the efficiency of the design process and expand the range of proposed alternatives.
The research recommends adopting a hybrid approach that utilizes AI capabilities in generating ideas and exploring design scenarios, while maintaining the designer's pivotal role in verifying and adjusting the outputs to ensure the highest levels of functional and aesthetic quality.
