Portrait of Mingming Zhao

Mingming Zhao holds a PhD in Architecture and is a LEED AP. She is a Research Assistant at the Design + Augmented Intelligence Lab (DAIL) at Cornell University, Executive Editor of Design Principle & Practice and Amps, and a committee member of the Academy of Neuroscience for Architecture (ANFA) and the Environmental Design Research Association (EDRA). She previously served as a visiting reviewer at the Wentworth Institute of Technology (WIT) School of Architecture.

Mingming Zhao has served as a reviewer for several international journals and conferences, including CAADRIA, SIGraDi, EDRA, ANFA, and Child Architecture. Her research focuses on neuroarchitecture, mixed reality (MR), human-computer interaction (HCI), brain-computer interface (BCI), multimodal physiological signal monitoring (EEG/HRV/eye-tracking), and 3D spatial emotion perception assessment, aiming to provide data-driven optimization strategies for the design of stress-sensitive spaces such as office and medical environments. Her research findings have been published in journals such as Journal of Environmental Psychology, npj Materials Sustainability, ACADIA 2024, EDRA 2024, and CAADRIA 2023, and have also received funding from the CUHK Seed Funding.

Work Statement

Affective Brooch is a wearable interface that translates physiological signals into socially legible cues. ECG data from a Polar H10 chest strap is processed through a custom Python pipeline and transmitted via BLE to an Arduino-based brooch containing an RGB LED, a micro-motor and a side button. Light indicates physiological activation (calm or heightened); opening or closing the form indicates user-declared social readiness, producing four public states: Approachable, Quiet, Engaged, and Needs Space.

Wearing Affect: A Bioresponsive Brooch for Emotional Visibility and Social Negotiation was presented in Mind × Body: Catalyst Phenomenon Archive, organised by the Reality Intelligence Association as part of London Design Festival 2026.
