Boréas Technologies AR Glasses

Picture effortlessly browsing through options, modifying audio levels, or making selections directly on an AR device temple area—achieved through natural touch interactions. Through the fusion of capacitive recognition and the Boréas piezo haptic platform, the Solid-State Button functions as both responsive activation control and an adaptive adjustment mechanism, generating unique tactile signatures for various operations.

Featuring pressure detection that prevents unintended activations and focused haptic confirmation that validates each command without disturbing the entire frame structure, users achieve assured, discreet operation through vibration feedback instead of intrusive sound notifications.

The Invisible Control Challenge: Capacitive Systems Fall Short in Non-Visual Environments

Contemporary AR eyewear encounters a fundamental interaction obstacle: users need to operate sophisticated digital controls via buttons and surfaces located on temple areas—entirely beyond visual range. Existing capacitive solutions, despite their slim profiles, create uncertainty about successful input registration, menu navigation, or parameter modification.

This "sightless operation" issue intensifies during complex menu traversal or fine-tuned adjustments. Lacking tactile validation, users engage in repetitive pressing attempts, inadvertently activating incorrect features, or abandoning the experience entirely to rely on secondary mobile applications. Each ambiguous interaction disrupts the seamless AR environment and disappoints users accustomed to the reliable responsiveness found in their mobile devices.

The disconnect between expected smartphone-level control precision and current AR interface limitations creates a significant usability gap that undermines the technology's potential for widespread adoption.

The Boréas Solid-State Button converts individual touch areas into diverse control mechanisms. Tap for confirmation, swipe for menu browsing, or adjust pressure intensity for varied operations. The piezo platform generates unique haptic signatures corresponding to each input method through discrete vibration responses, rather than intrusive sound alerts.

Contrasting with LRAs that vibrate complete device structures, our piezo haptic system provides focused feedback exactly at user contact points while maintaining a comfortable wearing experience—no disturbing facial sensations that could render extended AR usage intolerable, solving essential wearable AR engineering challenges.

Pressure-detection innovation measures genuine force application rather than mere surface contact, preventing unintended triggering common in capacitive interfaces. Users may rest fingers naturally on controls without causing unwanted responses, while deliberate inputs generate an instant haptic acknowledgment. This accuracy proves essential for AR interface management during active operation.
