Viture Luma Ultra 6DOF Development

Unity XR project targeting the Viture Luma Ultra glasses with their proprietary 6DOF dev kit. Covers application development using the Viture XR SDK, hand tracking, skeletal gestures, and spatial computing on the Luma Ultra hardware.

Hardware

Viture Luma Ultra XR Glasses

• Proprietary on-device 6DOF chip — full positional + rotational tracking, no external base station
• Skeletal hand tracking with gesture recognition (pinch, grab, point, etc.)
• USB-C connection to compute host (Android phone, PC, or dedicated compute module)

6DOF Dev Kit

• Unlocks full 6DOF positional + rotational tracking APIs
• Required for head pose, hand pose, and spatial anchor features

Prerequisites

Requirement	Version / Notes
Unity Editor	6 LTS (6000.x) recommended; 2022.3 LTS minimum
Render Pipeline	Universal Render Pipeline (URP) — required
XR Interaction Toolkit	Install from Unity Registry
XR Hands	Install from Unity Registry
Viture XR SDK	com.viture.xr — place in Packages/
Android Build Support	Target API 29+

Project Setup

1. Create Unity Project

Open Unity Hub → New Project → Universal 3D template.

2. Install Registry Packages

Window → Package Manager → Unity Registry, install:

• XR Interaction Toolkit
• XR Hands

3. Install the Viture XR SDK

Copy the Viture SDK into the Packages/ directory:

Packages/
  com.viture.xr/         ← SDK goes here
    package.json
    Runtime/
    Editor/

The SDK directory is tracked in git so it ships with the project.

4. Configure XR Plug-in Management

• Edit → Project Settings → XR Plug-in Management
• Enable Viture XR on the Android tab
• Set Stereo Rendering Mode to Single Pass Instanced

5. Build Target

• Platform: Android
• Minimum API Level: 29
• Scripting Backend: IL2CPP
• Target Architecture: ARM64

Key Development Concepts

6DOF Head Tracking

The Luma Ultra handles 6DOF on-device. Head pose is available via the standard XR Input subsystem once the Viture plug-in is enabled:

using UnityEngine.XR;

var headDevice = InputDevices.GetDeviceAtXRNode(XRNode.Head);
headDevice.TryGetFeatureValue(CommonUsages.devicePosition, out Vector3 pos);
headDevice.TryGetFeatureValue(CommonUsages.deviceRotation, out Quaternion rot);

Or use the XROrigin rig from XR Interaction Toolkit — it handles head tracking automatically via the Camera Offset + Main Camera hierarchy.

Hand Tracking

using UnityEngine.XR.Hands;

var handSubsystems = new List<XRHandSubsystem>();
SubsystemManager.GetSubsystems(handSubsystems);
var subsystem = handSubsystems[0];
subsystem.Start();

// Per-frame joint access
XRHand hand = subsystem.leftHand;
if (hand.GetJoint(XRHandJointID.IndexTip, out XRHandJoint joint))
    joint.TryGetPose(out Pose tipPose);

Gestures

The Viture SDK layers gesture recognition on top of skeletal data. See Assets/Scripts/Gestures/ for event-driven wrappers around the Viture gesture API.

Branch Workflow

feature/<name>  →  main

• Work on feature branches
• Test on-device before merging (Viture hardware required for full validation)
• Keep ProjectSettings/ committed so XR config stays in sync across machines
