Core terminology

Spatial computing
fundamentals.

3DoF (Three Degrees of Freedom)

Rotational tracking only (yaw, pitch, roll). Used primarily in entry-level headsets where positional movement in 3D space is not required. QWR's VRone Edu is a 3DoF platform optimised for seated classroom experiences.

6DoF (Six Degrees of Freedom)

Full rotational and positional tracking, allowing users to physically walk within a virtual or mixed environment. Essential for room-scale simulation, industrial training, and surgical rehearsal. QWR's VRone Pro and 4K are 6DoF platforms.

XR (Extended Reality)

An umbrella term covering Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). XR is the overarching category of immersive technologies QWR designs hardware for.

Passthrough

A camera-based view of the real world displayed inside a headset. Advanced RGB passthrough (as featured on VRone Pro and VRone 4K) enables high-fidelity Mixed Reality on opaque headsets.

SLAM (Simultaneous Localisation and Mapping)

Algorithms that build a real-time 3D map of the environment while simultaneously tracking the device's position within it. The foundation of QWR's inside-out 6DoF tracking systems.

Optics & display technology

How the display
reaches your eyes.

Waveguide

An optical component that channels light from a micro-display to the user's eye via total internal reflection, enabling transparent AR displays. The core optical technology in QWR's HUMBL AI Glasses.

Pancake Lens

A folded optics design that bounces light between polarizing layers, significantly reducing headset depth compared to traditional Fresnel lenses. Used in QWR's VRone Pro and VRone PC for compact form factors.

Micro-OLED

A high-density display technology providing superior contrast ratios and pixels per inch (PPI). The VRone 4K features Micro-OLED at 3,882 PPI — essential for medical visualization and high-fidelity engineering.

LCoS (Liquid Crystal on Silicon)

A micro-display technology used in AR light engines providing high-output brightness up to 2,500 nits. The production-validated approach for enterprise AR glasses manufacturing at high volumes.

FOV (Field of View)

The angular extent of the visible world through a headset, measured in degrees diagonal. A wider FOV increases user immersion. QWR's VRone platforms range from 90–110°.

Sovereign trust & compliance

India-specific
regulatory terms.

Make in India Class 1

A domestic content status that makes QWR a primary choice for institutional tenders and state-led ICT initiatives. Qualifies hardware for GeM procurement and Samagra Shiksha-aligned education deployments.

DAP 2020 (Defence Acquisition Procedure)

The primary framework for military procurement in India. QWR hardware meets "Buy Indian" (IDDM) categories under this procedure, making it eligible for Indian Army, Navy, and Air Force tenders.

DPDP Act (2023)

The Digital Personal Data Protection Act 2023. QWR uses secure boot and on-device processing to ensure data residency compliance — all user data resides on AWS Mumbai servers.

BIS Certification

The Bureau of Indian Standards. BIS certification validates that QWR electronics meet mandatory Indian safety and quality standards, required for all institutional and commercial deployments in India.

Manufacturing & software

Engineering
terminology.

ODM (Original Design Manufacturer)

A partner that designs and manufactures products for other companies to rebrand and sell. QWR is India's leading ODM for head-worn computing, offering 110+ reference architectures.

OEM (Original Equipment Manufacturer)

A partner that manufactures hardware to a client's exact design and technical specification. QWR's OEM service provides a 9–11 month development-to-production timeline.

BSP (Board Support Package)

The software layer including kernels and drivers that enables an OS to run on specific hardware. Every QWR ODM project includes a full BSP handoff to the partner engineering team.

AOSP (Android Open Source Project)

The foundational operating system for QWR devices. A "Clean AOSP" build ensures native compatibility with enterprise MDM tools like Microsoft Intune — and no foreign bloatware.

OTA (Over-The-Air Updates)

Wireless delivery of software or firmware to a device. Critical for managing large-scale classroom or enterprise fleets, OTA enables delta updates with staged rollout and automatic rollback.
