OBJECTIVE
The core development challenge for the HelloChair project was moving beyond traditional single-item customization to engineer a fully interactive, multi-object 3D environment.
We needed to build a sophisticated spatial logic system allowing users to simultaneously configure a central dining table while actively arranging multiple independent, highly customizable chairs around it. The objective was to create an advanced digital room-planning tool capable of handling massive parameter permutations and complex data states without sacrificing real-time browser performance or e-commerce synchronization.
SOLUTION
We developed a complex, state-driven 3D configurator utilizing an advanced scene-graph architecture. This allows users to actively click, drag, position, and interact with multiple separate objects within the same 3D canvas.
To manage the immense data load of structural and material variables, we engineered a dual-mode editing logic: the system state can dynamically switch between applying parameter changes to "All chairs same" or allowing users to "Customize each" unit independently.
This dynamic scene assembly is seamlessly tied to a reactive real-time pricing engine and web-native AR for life-size room visualization.
KEY FEATURES
01
DYNAMIC ASSEMBLY
Unlike standard configurators, users actively build their scene. They can configure the main table - selecting specific colors and shapes - while dragging and dropping various chair models directly into the 3D space. On-canvas UI tools allow for intuitive rotation, duplication, and deletion of individual pieces on the fly.
02
DUAL-MODE EDITING
To handle the complexity of mixed dining sets, the system features a robust state manager. Users can instantly toggle between batch-editing the entire set or applying highly granular, independent parameters - such as unique upholstery colors, specific base types, and even floor glides - to a single specific chair within the group.
03
PRICING & AR
The configurator continuously calculates the combined cost of the complex, multi-item scene, pushing the complete setup to the shopping cart with a single click.
Additionally, the "BEKIJK IN HUIS" (View in home) feature empowers customers to project their entirely custom, multi-piece dining arrangement directly into their physical room via Augmented Reality to verify spatial footprint and design harmony.
THE RESULT
By empowering customers to independently design, assemble, and spatially validate complex dining arrangements in a single browser session, the platform significantly reduces buyer hesitation for high-ticket furniture.
This advanced scene-building approach not only streamlines the custom ordering process but actively drives higher average order values by encouraging users to curate and purchase complete, perfectly matched room sets rather than isolated pieces.
