The "Bamboo Tactic: gesture recognition for design generation" project explores a new design-construction collaboration model using gesture recognition in mixed reality (MR) for non-expert builders. The project employs active bending of lightweight bamboo modules, integrating physics-based form-finding algorithms with intuitive gesture-based input. This custom digital workflow enables site-specific design by syncing topographic conditions and construction guidelines. Gesture recognition allows for the easy recording of site data, generating modular bamboo structures that adapt to site variables. The process facilitates non-expert participation, bridging design and construction knowledge while revitalizing bamboo construction through innovative digital tools.

Bamboo is widely accessible as a sustainable natural resource with unique non-uniform material and structural characteristics. The research leverages mixed-reality (MR) enhanced design workflow to discover a catalog of new material tactics for the application, customization, and fabrication of bamboo for architectural assemblies. The investigation studies how low-tech material tactics can be augmented by emergent technologies such as AR tools and digital tools to reimagine hybridized material and construction systems.
