Noparde Completes Field Tests for Beach Interactive Projections: Advancing Outdoor Sensing & Touch Integration

Noparde has wrapped up rigorous field tests for its beach interactive projection system in southern Spain, focusing on optimizing outdoor motion sensing and touch-response performance. The trials—designed to mimic real beach conditions like sand, salt, and shifting light—confirmed the system’s reliability, paving the way for its deployment in tourism and public leisure spaces.
The Testing Mandate: Overcoming Beach-Specific Technical Barriers
Beach environments pose unique challenges for interactive projection systems, far more demanding than indoor or even standard outdoor settings. Noparde’s engineering team identified three core hurdles to address during testing:
- Variable Sensing Interference: Sand particles, blowing debris, and changing sunlight (from bright midday glare to dusk) can disrupt motion detectors, leading to false triggers or unresponsive interactions.
- Touch Response on Uneven Surfaces: Unlike smooth indoor floors, beach sand is uneven, shifting, and porous—making it difficult for touch-sensitive technology to register precise user inputs.
- Environmental Durability: Saltwater mist, high humidity, and extreme temperature swings (from 25°C to 40°C during the trials) threaten the longevity and performance of electronic components.
“The goal wasn’t just to ‘make projections work on a beach’—it was to make the interaction feel natural,” explains Dr. Marcus Hale, Noparde’s Lead Systems Engineer. “A visitor should be able to tap the sand and see a wave pattern ripple, or walk through a projected tide pool and watch fish scatter—without lag, without false triggers, even on a windy day.”
The Technical Setup: Customized Sensing & Projection for Coastal Use
To address these challenges, Noparde’s team deployed a specialized prototype system tailored to beach conditions, combining advanced sensing hardware with adaptive software:
1. Dual-Mode Sensing Technology for Accuracy
The system integrated two complementary sensing layers to cut through beach interference:
- 3D LiDAR Sensors: Calibrated to filter out small, fast-moving objects (like blowing sand or leaves) by focusing on human-sized heat signatures and movement patterns. The LiDAR’s range was adjusted to 5–8 meters—ideal for beachgoers’ typical interaction zones—with a refresh rate of 60Hz to ensure real-time response.
- Pressure-Sensitive Subsurface Grids: Embedded 2cm below the sand surface in key interaction areas (e.g., a 10m x 10m “tide pool” projection zone), these grids detect physical touch by measuring subtle pressure changes. Unlike surface-mounted sensors, they’re protected from sand and water, with a waterproof rating of IP68.
Together, these layers created a “redundant sensing network”: LiDAR tracked movement across larger areas, while the pressure grids handled precise touch inputs—eliminating 92% of false triggers during testing, according to Noparde’s data.
2. Adaptive Projection Mapping for Uneven Terrain
The team used Noparde’s proprietary 3D terrain mapping software to scan the beach’s shifting sand surface twice daily (morning and evening) and adjust projections in real time. This ensured:
- Distortion-Free Visuals: Projections of tide pools, seashells, and wave patterns maintained their shape even as sand dunes shifted—critical for preserving the illusion of a “living” beach environment.
- Brightness Auto-Calibration: The system’s 30,000-lumen projectors (housed in salt-resistant aluminum enclosures) adjusted brightness based on ambient light: cranking up to 100% during midday, dimming to 40% at dusk, and switching to warm-toned projections after sunset to avoid glare.
3. Weather-Sealed Hardware for Durability
Every component was engineered for coastal resilience:
- Sensor and projector enclosures featured corrosion-resistant coatings to repel saltwater mist.
- Cables were routed through buried, waterproof conduits to protect against sand and water damage.
- A solar-powered backup system ensured continuous operation even during temporary power outages—common in remote beach areas.
Trial Results: Immersive Interaction, Even in Harsh Conditions
Over 14 days, the system was tested across 12-hour cycles (8 AM to 8 PM), with 50+ volunteer participants simulating typical beachgoer behavior: walking, sitting, touching the sand, and interacting with projected elements. The data revealed standout performance:
- Sensing Accuracy: The dual-mode system registered 98% of intentional user interactions (e.g., tapping a projected seashell, stepping into a tide pool) with no false triggers from sand or wind. Even during a 30-minute afternoon gust (wind speeds up to 25 km/h), response accuracy dropped by only 3%.
- Touch Responsiveness: Pressure-sensitive grids detected light touches (as gentle as a child’s finger tap) through 1–2cm of sand, with a response time of 0.3 seconds—fast enough to feel “instant” to users.
- Projection Stability: Adaptive mapping kept visuals crisp and undistorted, even as sand shifted by up to 5cm overnight. Participants reported that the projections “blended with the beach” rather than feeling like a superimposed layer— a key metric for immersion.
“One of the biggest wins was watching kids interact with the projected tide pools,” says Hale. “They’d chase projected fish across the sand, and the system would track their movements perfectly—even when they kicked up sand or knelt down to ‘touch’ a fish. That’s the natural interaction we were aiming for.”
Future Deployment: Bringing Interactive Beaches to Public Spaces
With testing complete, Noparde plans to refine the system for commercial deployment in Q1 2025, targeting coastal resorts, public beach parks, and tourism destinations. The first pilot projects are already scheduled for two locations: a family-friendly beach in Portugal and a coastal boardwalk in Australia.
The system’s flexibility will allow venues to customize projections to their brand or local culture—for example, a tropical beach could feature projected sea turtles and palm fronds, while a coastal city boardwalk might include interactive tide charts or local marine life facts.
“Beaches are places of relaxation and play, and technology should enhance that—not distract from it,” says Elena Marquez, Noparde’s Product Strategy Director. “Our beach interactive projection system doesn’t just add visuals; it adds a layer of joy that brings people closer to the ocean environment—all while standing up to the beach’s toughest conditions.”
Why This Matters for Outdoor Interactive Technology
Noparde’s trials represent a step forward for outdoor projection, proving that interactive systems can thrive in harsh, uncontrolled environments. By focusing on beach-specific challenges—rather than adapting indoor technology— the team has created a solution that’s both durable and immersive, opening new possibilities for public spaces.
As Hale puts it: “The beach doesn’t care about ‘standard’ outdoor specs. It throws sand, salt, and sun at your equipment. Our job was to build something that doesn’t just survive that—it works better because of it. These trials show we’ve done that.”
