# Inside-Out Interaction Design

### Mapping native WebXR finger coordinates and knuckle rotations to allow users to pinch, grab, and manipulate digital objects.

**STD.DEV engineers bespoke spatial interaction frameworks that unlock extensive architectural flexibility, enabling users to manipulate virtual elements through highly customized workflows.** By mapping native WebXR skeletal finger joints and knuckle rotations directly to dynamic canvas behaviors, the pipeline converts physical movements into customized interactive triggers. This bespoke integration goes far beyond default gestures, allowing brands to orchestrate tailored, zero-install mixed-reality installations that react immediately to user behavior.

### Unrestricted Gesture Customization

Instead of using rigid, pre-packaged gesture libraries, STD.DEV custom-calibrates skeletal recognition layers to map twenty-five distinct joint vectors. This allows the integration of novel hand-shapes and movements tailored to specific creative concepts, translating organic hand shapes into complex, multi-axis system controls.

### Volumetric Manipulation Systems

The custom interaction framework enables users to pinch, squeeze, morph, and disassemble 3D assets in real time with high physical accuracy. By linking hand velocity and position vectors directly to shader uniforms and physics simulation matrices running directly on the GPU, the architecture supports granular control in sculpting, rotating, and morphing digital geometry.

### Interactive Haptic Feedback

To ground these creative interactions in physical reality, STD.DEV maps hand movement trajectories and controller triggers to complex haptic responses. The engine dynamically coordinates vibration frequency and force feedback based on material density and velocity, providing sensory reinforcement that bridges visual fidelity with a grounded physical presence.
