Key Capabilities

Integrating complex technologies into a single HMI

Designed for demanding environments where operators need to interact via screens, pointing devices, and physical buttons simultaneously.

Hybrid Sensor Integration

Combines mechanical switches, capacitive surfaces, and tactile domes into a unified console control board.

Optical Pointing Devices

Integrates aerospace-grade optical trackballs or rugged multi-touch pads for precise cursor control in medical and naval consoles.

Integrated Display Panels

Seamless optical bonding of cover glass or touch overlays onto TFT displays to ensure condensation-free and sunlight-readable views.

Embedded Microcontrollers

Industrial onboard microcontrollers handling key mapping, debouncing, trackball tracking, and USB/CAN/Ethernet conversion.

Rotary Dial Knobs

Sealed optical or mechanical rotary encoders offering positive tactile step increments for reliable speed and frequency settings.

High-Grade Shielding

Advanced Faraday cage structures, grounding gaskets, and ITO glass windows to suppress electromagnetic interference (EMI).

Hybrid Integrated Console Panel
Hybrid Interface Design

Next-generation human-machine interfaces
