Human-Centered UAV Control System
Project Overview
Traditional military UAV control systems often require bulky controllers and separate displays that limit operator mobility and divide attention.
This concept explores a wearable, one-handed UAV control system that combines an ergonomic controller with a forearm-mounted display, allowing operators to maintain mobility while keeping mission-critical information within view.
The design focuses on human factors, anthropometric sizing, intuitive control placement, and iterative physical prototyping to improve comfort, reduce fatigue, and support faster decision-making during extended missions.
Full-Scale Final Prototype
The final full-scale prototype was used to evaluate grip comfort, finger placement, and control accessibility. Multiple views showcase the finalized geometry developed through earlier foam and clay iterations.
Operational Scenario
The wearable system enables UAV operation while allowing the operator to remain mobile, maintain situational awareness, and interact with surrounding equipment or teammates without setting down a conventional controller.
The forearm-mounted display reduces repeated head and hand movement by positioning mission information directly within the operator's natural viewing angle.
Modular Wearable Display
The forearm display was designed as a modular platform using a ball-joint mounting interface that allows the screen angle to be adjusted for different operators and mission requirements.
The wearable configuration keeps mission data accessible while preserving mobility during movement.

Concept Ideation
Early Prototypes
Control Hierarchy & Reach Zones
Control placement was prioritized based on interaction frequency and ergonomic reach.
Primary Reach Zone (Green)
Thumb joystick (Pitch / Yaw)
Throttle trigger
Payload trigger
Manual override
These controls remain within the operator's natural resting position, minimizing thumb travel and reducing fatigue during repetitive flight tasks.
Intentional Reach Zone (Red)
Return Home
Kill Switch
Mode Selection
Communications
Lower-frequency controls were intentionally positioned outside the primary reach envelope to reduce accidental activation while remaining accessible when needed
CAD Design
The final design directions integrate a one-handed controller with a wearable forearm display through a modular mounting system.
The controller geometry was refined using anthropometric hand dimensions and optimized for prolonged operation while wearing tactical gloves.
The wearable display keeps navigation, telemetry, and mission information within the operator's field of view without occupying the off-hand.
Iterative Form Development
Four full-scale prototypes were produced to refine the overall grip geometry.

Each iteration adjusted:
Finger groove spacing
Palm support
Thumb posture
Overall grip diameter
Glove compatibility
Reach to primary controls
The final geometry balanced long-term comfort with confident one-handed control.
Human Factors Considerations

• Thumb resting position
• Finger groove geometry
• One-handed balance
• Reduced thumb travel
• Anthropometric sizing
• Tactical glove compatibility
• Adjustable forearm display
• Display positioned within natural field of view
• Preserved off-hand mobility
