Olfactory and Haptic Engineering at The Mukaab
The Mukaab’s promise of “multi-layered sensory immersion” blending “sight, sound, and touch in perfect harmony” extends beyond the holographic dome and spatial audio systems to encompass olfactory (scent), haptic (touch), and environmental (temperature, wind, humidity) systems. These sensory layers transform passive viewing into embodied experience — the difference between watching a forest scene on a screen and feeling that you are standing in the forest. This analysis examines the technology requirements, deployment challenges, and vendor landscape for The Mukaab’s non-audiovisual sensory systems.
The Neuroscience of Multi-Sensory Immersion
Human perception research consistently demonstrates that adding sensory channels beyond sight and sound dramatically increases immersion, emotional engagement, and memory formation. Olfactory cues in particular activate the limbic system — the brain’s emotional processing center — more directly than any other sense. A study published in Chemical Senses found that congruent scent cues increased perceived immersion by 43% compared to audiovisual-only environments. For The Mukaab’s target of transporting visitors to “the Serengeti one day and magical worlds the next,” scent is not optional — it is architecturally necessary for the experience to function as designed.
The Las Vegas Sphere pioneered multi-sensory integration at entertainment venue scale, deploying three non-audiovisual systems simultaneously: a custom haptic floor that vibrates to different frequencies simulating motorcycle rides and earthquakes, 4D wind and cooling effect generators that create directional airflow matched to visual content, and an olfactory system releasing themed scents synchronized with visual scenes. The Sphere’s multi-sensory approach has been commercially validated — its immersive film experiences consistently sell out, with audience satisfaction scores exceeding traditional cinema by significant margins according to industry reporting.
Olfactory System Architecture
Scent delivery at The Mukaab’s scale presents unique engineering challenges that exceed any existing installation:
Zone-Specific Scent Delivery — The Mukaab’s 80+ entertainment venues will operate different themed environments simultaneously, each requiring distinct scent profiles. A tropical rainforest zone needs humidity, earth, and floral scents. A Martian landscape needs mineral and metallic notes. A luxury retail district needs neutral or premium ambient fragrances. These scents must be delivered to specific zones without cross-contamination — a visitor stepping from the rainforest into the Martian landscape should experience an immediate scent transition.
Current scent delivery technology uses several approaches. Heated evaporation systems vaporize scent oils and distribute them through HVAC ducts — effective for large areas but slow to change and difficult to contain. Cold-air diffusion systems nebulize scent oils into micro-particles that remain suspended in air, offering faster scene changes but requiring more hardware. Localized scent delivery devices, positioned at individual visitor touchpoints (seats, display cases, experience pods), provide precise control but cannot create ambient environmental scent.
HVAC Integration — The Mukaab’s internal climate control system, managing temperatures for 104,000 residential units, 9,000 hotel rooms, and 980,000 square meters of retail alongside entertainment venues, must integrate scent delivery without compromising air quality or comfort. Scent molecules must be actively extracted from zones after use to prevent buildup and enable rapid scene changes. This requires dedicated extraction fans, filtration systems, and airflow management operating alongside the primary HVAC infrastructure.
Scent Library Management — A venue operating hundreds of simultaneous environments needs a scent library of thousands of compounds, stored in concentrated form and diluted to safe atmospheric concentrations during delivery. Storage, mixing, and delivery systems must be automated and centrally managed, with real-time monitoring for air quality compliance. The vendor landscape includes established scent marketing companies like ScentAir, Prolitec, and AirAroma, though none have deployed at the scale The Mukaab requires.
Haptic System Technology
Haptic systems at The Mukaab will likely operate at two scales:
Floor-Level Haptic Platforms — Following the Sphere’s precedent, vibration platforms integrated into flooring can simulate surface textures, vehicle motion, seismic events, and environmental vibrations (waterfall rumble, wind buffeting). The Sphere’s haptic floor uses transducer arrays that convert audio-frequency signals into physical vibrations, creating localized tactile effects matched to the visual content. For The Mukaab’s observation platforms in the spiral tower, haptic flooring could simulate wind sway, creating a visceral sense of height that enhances the physical elevation.
At Mukaab scale, haptic flooring across the full entertainment zone footprint would require millions of individual transducer elements, representing a manufacturing and installation challenge comparable to the dome’s display systems. Selective deployment in high-impact zones — attraction entrances, observation decks, cinematic experiences, themed walkways — offers a more practical approach.
Wearable Haptic Devices — Haptic vests, gloves, and wristbands can provide personalized tactile feedback synchronized with visual and audio content. Universal’s theme parks have experimented with ride-integrated haptic effects, and gaming-focused companies like bHaptics and Woojer produce consumer haptic vests. For The Mukaab’s visitor experience design, providing visitors with optional haptic wearables at venue entry points could add a personalized tactile layer without requiring full-floor haptic installation.
Environmental Effect Systems
Beyond scent and touch, The Mukaab’s immersive environments require environmental controls that create physical sensations of temperature, wind, humidity, and atmospheric pressure:
Wind Generation — Directional wind effects, used extensively in theme park rides and the Sphere’s 4D system, create physical awareness of environment and movement. At The Mukaab’s scale, wind generation must operate within enclosed zones without disrupting adjacent areas — requiring ducted air systems with precise directional control. The dome’s Serengeti scene needs warm dry wind; the ocean scene needs cool salt-tinged airflow; the urban scene needs ambient air movement without strong directional effects.
Temperature Zones — The ability to create localized temperature variations enhances environmental immersion. Moving from a tropical zone (warm, humid) to a polar zone (cold, dry) within the same building requires rapid air conditioning transitions. Modern HVAC systems using variable refrigerant flow (VRF) technology can create temperature differentials of 5-10 degrees Celsius between adjacent zones, though the energy cost at Mukaab scale is substantial.
Humidity Control — Tropical environments feel humid; desert environments feel dry; alpine environments feel crisp. Precision humidity control, using ultrasonic humidifiers for wet zones and desiccant dehumidifiers for dry zones, adds another sensory layer that reinforces the dome’s visual content.
Lighting Integration — While primarily a visual system, localized lighting plays a haptic-adjacent role by defining space boundaries and creating physical awareness of environment changes. Smart glass technology — electrochromic glass that can switch between transparent and opaque states — could define zone boundaries dynamically, creating visible walls that appear and disappear as visitors move through the cube.
Cost and Implementation Considerations
Multi-sensory systems at Mukaab scale likely represent a $200-500 million subsystem investment, distributed across olfactory infrastructure, haptic platforms, environmental control hardware, and integration with the master content management system. The implementation challenge is less about any single technology and more about orchestrating dozens of sensory systems across 80+ venues in real-time synchronization with the holographic dome and spatial audio.
Falcon’s Creative Group’s role as Creative Lead Advisor, developing the storytelling framework within which all sensory systems operate, positions them to define the multi-sensory integration architecture. Their mandate to develop 10+ key attractions requires specifying the sensory requirements for each attraction, which in turn drives subsystem specifications for the entire building.

Scent Library and Cultural Sensitivity
The Mukaab’s olfactory system requires a curated scent library spanning hundreds of individual scent compounds, organized into themed palettes aligned with the dome’s environmental content categories. A Serengeti scene requires savanna scents (dry grass, acacia wood, warm earth, animal presence); a New York City scene requires urban scents (asphalt after rain, coffee, food vendor aromatics); a Mars environment requires sterile, mineral scents (iron oxide, ozone, cold stone).
Cultural sensitivity adds a layer of complexity to scent design. Saudi Arabia’s diverse visitor population — domestic Saudi citizens, Gulf region tourists, European and Asian international visitors — brings different scent associations and sensitivities. Scents considered pleasant in one culture may be neutral or unpleasant in another. The scent design team must consider Islamic sensitivities (avoiding alcohol-based scents in certain contexts), regional preferences (oud and frankincense carry cultural significance in the Gulf region), and medical sensitivities (some visitors may have asthma or chemical sensitivities requiring scent-reduced zone options).
The scent delivery infrastructure must handle rapid transitions between environments. When the dome shifts from a tropical beach scene to a mountain forest, the olfactory system must extract ocean salt and coconut scents while introducing pine, cedar, and cold air within 30-60 seconds. This extraction speed depends on zone air handling — dedicated high-velocity air exchanges in each zone flush residual scents and introduce new ones. The HVAC investment for scent-capable zone ventilation exceeds standard building ventilation by an estimated 40-60%, adding to both capital cost and ongoing energy expense.
Strategic Outlook and Forward Indicators
The trajectory of this domain within The Mukaab’s development timeline is shaped by several converging factors. Saudi Arabia’s $196 billion in awarded tourism contracts since Vision 2030’s launch in 2016 demonstrates sustained investment commitment at national scale. The kingdom’s tourism target — 150 million annual visitors by 2030, having already surpassed its initial 100 million target ahead of schedule — creates demand-side pressure for experience infrastructure that The Mukaab is designed to serve.
The New Murabba Development Company’s continued participation in MIPIM 2026 in Cannes in March 2026, following the January 2026 construction suspension, signals that project planning and partnership development continue even as construction timeline adjustments are evaluated. This pattern is consistent with other Saudi megaprojects that have experienced timeline shifts while maintaining long-term strategic commitment.
The $50 billion total investment in New Murabba and the projected SAR 180 billion ($48 billion) contribution to Saudi non-oil GDP position The Mukaab as more than an entertainment project — it is infrastructure for Saudi Arabia’s economic transformation. The building’s 104,000 residential units, 9,000 hotel rooms, 980,000 square meters of retail, and 620,000 square meters of leisure space create an integrated urban economy where immersive technology adds value to every square meter.
For technology vendors, the strategic calculus extends beyond The Mukaab itself. Successful deployment of immersive systems at Mukaab scale creates reference installations applicable to Saudi Arabia’s broader megaproject pipeline — Qiddiya, the Red Sea Project ($10 billion), Diriyah ($62.2 billion), and future projects not yet announced. The global experiential market’s projected growth from $132 billion (2025) to $543.45 billion (2035) at 23.05% APAC CAGR provides the commercial backdrop for long-term technology investment decisions.

Integration Testing and Multi-Sensory Calibration
The most critical challenge in multi-sensory engineering is integration — ensuring that visual, audio, olfactory, haptic, and thermal systems operate as a unified experience rather than independent technology demonstrations. Integration testing at The Mukaab must verify that scent delivery aligns temporally with dome content transitions (forest scent arriving simultaneously with forest visual content), that haptic effects synchronize with audio events (floor vibration matching thunder sounds within 50 milliseconds), and that thermal transitions track with visual and olfactory transitions (cooling beginning when snow scenes appear and winter scents activate). The integration testing phase, estimated at 6-12 months for multi-sensory systems alone, requires dedicated testing zones where all technology systems operate simultaneously while measurement equipment verifies synchronization accuracy. Iterative calibration — adjusting timing, intensity, and spatial distribution based on test results and visitor focus group feedback — refines the multi-sensory experience from technically functional to emotionally compelling.
Multi-Sensory Integration and The Mukaab’s Revenue Model
The 42% immersion enhancement from congruent scent and the 30-50% perceived realism increase from haptic feedback translate directly into revenue justification. Every revenue stream within The Mukaab — 9,000 hotel rooms at $1,000-5,000/night, 980,000 square meters of experiential retail, 80+ entertainment venues, observation tickets at $50-150 — benefits from the multi-sensory enhancement that olfactory and haptic systems provide. The estimated $200-500 million investment in sensory engineering systems contributes to the SAR 180 billion ($48 billion) GDP projection by enhancing the value proposition of every commercial activity within the $50 billion New Murabba development.
