Applicable Devices: RayNeo X2 / X3 Pro and Similar Optical Waveguide/MicroLED Integrated Glasses
Applicable Scenarios: Assisted Reality, AI Assistant, Instant Information Display
1.
Core Design Principles (Core Principles)
The core of AI/AR glasses design lies in "Augment without Distraction" .
•
Real World First : UI is an "annotation" of the real world rather than a "mask". Black (#000000) is transparent , and the transparent area must be maximized to ensure users' safety perception of the environment.
•
Heads-up & Glanceable : Information should be presented within the natural line of sight, and interactions must support blind operation. Avoid users having to look down or focus on reading for an extended period.
•
Minimalism: Limited by FOV (Field of View) and computing power, all decorative elements are removed. Only the core text and icons are retained, pursuing extremely low information density.
•
Audio-Visual Synergy: Visuals only carry key "road sign" information, while detailed descriptions and secondary feedback are delegated to voice/audio interaction.

Hardware & Display Constraints
Attribute | Specifications (X2 / X3 Pro) | Design Constraints and AI Checkpoints |
Canvas Resolution | 640 x 480 px | All design drafts shall use this as the reference size. |
FOV | 25° (X2) 30° (X3 Pro) | The field of view is extremely narrow, covering only the central area. The content display of X3 Pro will be visually magnified 1.2 times compared to X2, and adaptation checks are required. |
PPD | - | Using 1px thin lines is prohibited. Lines must be ≥ 2px; otherwise, breaks or jagged edges will appear on the Optical Waveguide lens. |
Imaging Distance | Virtual image distance ~2m - 5m | Core information is placed in the 1.7m - 5m comfort zone to avoid visual fatigue and vergence-accommodation conflict. |
Safety Margin | Around the screen | Reserve at least 16px - 30px of black safety margins around the screen to avoid incomplete display caused by edge distortion or binocular parallax. |

Layout & Zoning
3.1
Degree of Freedom Mode (DoF Mode)
0 DOF (Recommended)
•
Description
AR glasses do not track any movement of the user's head; virtual information is fixedly displayed in front of the wearer's eyes and moves with the wearer's movement.
•
Applicable Scenarios
Currently, all system-level applications of the X Series glasses adopt the 0 DoF mode.
•
Interaction Limitation
Users cannot change their perspective by turning their heads or moving, and virtual information always remains in a fixed position.
•
Suitable for Interaction
Touchpad or button interaction, voice interaction.

3 DOF (used in combination with scenarios)
•
Description
AR glasses track the rotation of the user's head along the x, y, and z axes, but do not track positional translation.
•
Applicable Scenarios
360° panoramic video or panoramic image browsing.
•
Interaction Restrictions
Users can only move their perspective by "turning their heads" and cannot "walk into" virtual content. A "self-righting mechanism" is required.
•
Suitable for interaction
Touchpad or button interaction, voice interaction, and gesture interaction with fixed depth.

6 DOF (Exploration Scene)
•
Description
AR glasses can simultaneously track the rotation and positional translation of the user's head along the x-axis, y-axis, and z-axis, allowing the user to move freely within three-dimensional space.
