Digital Humans are photorealistic AI assistants on transparent OLED screens capable of handling up to 95% of routine lobby administrator tasks. Sub-Surface Scattering technology on Unreal Engine 5.4 reproduces living skin texture, while neural-mimicry synchronisation of 150 facial points at 60 Hz creates a sense of conscious presence. Built-in LiDAR sensors and 4K cameras in the reception desk identify visitors and switch to their language from over 150 available before the conversation even begins.
Digital Humans: Mimicry and Empathy
Unreal Engine 5.4+ with the MetaHuman module reproduces Sub-Surface Scattering of light in skin, creating texture indistinguishable from reality. Ocular micro-movements at 2-4 Hz simulate saccades, forming a sense of the assistant's conscious presence. Each Digital Human receives a unique biography, characteristic gestures and smile asymmetry to avoid the uncanny valley effect.
The neural-mimicry system reads 150 facial points via LiDAR and 4K cameras built into the reception desk. Micro-expression analysis determines the visitor's emotional state — confusion, haste, irritation — and adapts the assistant's tone, speech tempo and facial expression. Development cost for one Digital Human starts from 450 000 ₽, including 3D model, animation and speech module.
Multimodality: See, Hear, Understand
Real-time biometric analysis: pulse via video plethysmography, skin temperature, body micro-movements. The system identifies visitor needs before they are vocalised — for example, noticing a guest studying the floor plan and proactively offering navigation. Support for 150+ languages including dialects and professional terminology.
A transparent OLED screen with 45% transparency allows the Digital Human to literally 'hover' inside the reception desk. Face Recognition identifies returning visitors: name, preferred beverage, booked meeting room — all displayed before the guest approaches. CRM and access control integration via API takes 2-3 days.
24/7 Automation and Security
The AI assistant automates pass issuance, meeting room scheduling, building navigation and coffee ordering. The Frictionless Concierge function calls a taxi and prepares coffee 5 minutes before a meeting ends based on calendar data. Total automation covers 95% of routine administrator operations.
All computation runs on an Edge AI server inside the desk: data never leaves the building perimeter. Differential Privacy prevents identification of individual users in analytical reports. Emotional De-escalation protocols automatically shift an aggressive visitor to a calm tone while alerting security. SOC 2 Type II certified.
Hardware of Presence: Screens and Haptic Sound
An LG Transparent OLED panel (55-86 inch diagonal) is mounted in a reception desk body of tempered glass and anodised aluminium. Directed Audio Beamforming technology directs sound in a narrow beam to the specific visitor — the conversation is audible only to the interlocutor, even in an open lobby.
Haptic Sound Frames — low-frequency vibration modules in the desk countertop — create a tactile sensation of voice: the visitor literally 'feels' the greeting. Smart Glass conceals server hardware when the system is off. Full package starts from 1 200 000 ₽ including panel, server node and installation. Lead time is 6-8 weeks.
