**Sector:** SCORE XR Spatial Interaction & Input

# XR User Interaction

### Advanced interaction modalities combining hand tracking, controllers, and voice input.

> Multi-modal input methods including hand tracking, gaze-based selection, and neural input.

**Unifying hands, controllers, and voice input into a single control paradigm creates intuitive spatial experiences.** By routing varied physical tracking systems through a standardized selector pipeline, users can transition effortlessly between hardware buttons, skeletal gestures, and natural speech without interface friction.

**Unified Control Paradigm**

Unifies touch, pointer, controllers, and hands into a single selector flow. Users gain intuitive, frictionless control, while STD.DEV can design advanced interactions once and deploy them seamlessly across all devices.

**Centralized Spatial Data**

Aggregates user input states into a centralized data structure. Users experience latency-free responses, enabling STD.DEV to run physics simulations and GPU particle feedback triggered directly by physical motion.

**Agentic Voice Commands**

Translates natural speech into engine tool actions using agentic AI. Users enjoy effortless, hands-free control, allowing STD.DEV to build conversational, voice-driven interfaces that respond in real time.

**Ready to captivate your audience with unforgettable digital experiences?** Let’s transform your vision into extraordinary moments that inspire and engage.
