Mental-Gen: A Brain-Computer Interface-Based Interactive Method for Interior Space Generative Design

Yijiang Liu, Hui Wang

2024

Non-professional users often lack formal training and tools to express their design ideals. Current AI-assisted design tools rely primarily on language-based interaction, forcing users to repeatedly pause, verbalize incomplete thoughts, and translate them into precise prompts. Yet design is an iterative cognitive process in which vague mental images gradually become concrete through exploration. This project proposes a novel approach to refining/controlling generative AI models by user mental intentions decoded directly from brain signals (EEG).

Mindscape: Research of high-information density street environments based on electroencephalogram recording and virtual reality head-mounted simulation

Yijiang Liu, Xiangyu Guan, Hui Wang, Lun Liu

eCAADe · 2024

This study aims to investigate, through neuroscientific methods, the effects of particular architectural elements on pedestrian spatial cognition and experience in the analysis and design of walking street spaces. More precisely, this paper will describe the impact of the density variation of storefront signs on the brainwaves of passersby in East Asian city walking streets, providing strategies and guidelines for urban development and renewal.

Research progress in the intersection of brain science, architecture, and cities

Hui Wang, Yijiang Liu

Journal of Human Settlements in West China · 2025

Human cognition of space is inextricably linked to the workings of the brain, yet how the human brain operates remains shrouded in numerous mysteries. Related brain science research constitutes a cutting-edge scientific question demanding urgent exploration. Concurrently, with the gradual proliferation of artificial intelligence and generative design applications, interdisciplinary research integrating brain science and architecture can both enrich fundamental studies on spatial brain cognition and contribute to architectural theory and the innovative exploration of brain-computer interaction design methods.
