Multi-Axis Alignment (Actuation Stack)

Motorized motion primitives that reposition the display in real time to match user posture.

• Proximity (X-axis): moves the display toward/away from the user
• Height (Y-axis): raises/lowers the display to maintain eye-level alignment
• Optional orientation (tilt/rotation): adjusts viewing angle to match head tilt

Stability & Load Management (Mounting System)

A rigid base and guided mounts keep motion precise and prevent wobble, recoil, or tipping during adjustments.

• Flat base + fin supports: lateral stability and weight compensation
• Guided mounts: constrain motion and reduce mechanical play
• Pin-lock / modular coupling: repeatable assembly and serviceability

Universal Object Interface (Gripper / Third Mount)

A configurable attachment system designed to securely hold different display devices while enabling motion.

• Secure grip: clamps or modular adapters for different device types
• Alignment-aware geometry: maintains consistent orientation during movement
• Sensor-ready mounting: supports consistent vision capture direction

Vision Sensing Layer (Posture Capture)

A camera-based sensing layer captures real-time posture signals needed for alignment decisions.

• Head orientation: detects yaw/pitch/roll cues for framing and comfort
• Head tilt: estimates neck flexion/extension proxies
• Proximity: measures (or infers) distance to maintain ergonomic viewing range

Sensor configurations may include RGB, depth, or IR-assisted capture depending on implementation.

Posture Interpretation Engine (State + Metrics)

Converts visual input into stable posture states and ergonomic metrics, with quality gating for reliability.

• Landmarks / regions: identifies facial and upper-body reference points
• Postural metrics: angles, symmetry, and spatial relationships
• Quality assessment: confidence checks + re-capture when data is unreliable
• Session states: timestamps and posture snapshots for trend analysis

Alignment Intelligence (Closed-Loop Control)

A decision layer evaluates posture deviation against ergonomic tolerances and triggers smooth corrective action.

• Baseline calibration: establishes an ergonomic reference posture
• Deviation logic: rule-based tolerances (and optionally ML-based mapping)
• Command generation: translates adjustments into actuator movement commands
• Embedded control unit: motor drivers + coordinated multi-axis motion
• Feedback loop: re-check posture and micro-adjust as needed
