Samsung Electronics Brings the Live Moods of London to Life in Piccadilly Circus with a Real-Time, Data-Driven Experience

Samsung launches a new data-driven digital experience in Piccadilly Circus, created with Cheil UK, that transforms the live moods of London into dynamic real-time creative on the Iconic Piccadilly Lights screen

Samsung is unveiling a landmark digital experience in Piccadilly Circus that transforms the live moods of London into a responsive visual spectacle. Developed with integrated digital marketing and advertising agency Cheil UK, with media support from Landsec and Ocean Outdoor, the campaign aims to create mass awareness of Samsung’s leadership in AI-powered consumer technology.

The activation uses real-time environmental and behavioural data to turn the natural energy of Piccadilly Circus into dynamic, mood-based creative. The result is a living digital canvas that mirrors the changing rhythm of the city and reflects Samsung’s belief that technology should adapt to meet people’s desires.

As consumers seek healthier, more active and more balanced lifestyles, their needs and motivations shift each day. Samsung’s AI-enabled ecosystem is designed to support those moments, helping to make people’s everyday lives better and smarter.

A custom-built Mood Calculator captures and processes live data to generate a “Mood Score” for Piccadilly Circus, which determines which of six creative ‘mood’ states appears across the Piccadilly Lights. On launch day (17 December 2025), a large-scale lighting takeover will synchronise the surrounding architecture with the screen content mood colour. For the following six days, the responsive screen creative will continue to inspire visitors. Each mood state links directly to Samsung’s AI-enabled products and connected ecosystem, showing how AI already powers everyday life across home, health, entertainment and productivity.

To capture the city’s rhythm, the system processes anonymised crowd density and movement patterns, local weather conditions and time-of-day signals through an on-site data engine. The Piccadilly Lights then delivers full-motion displays of the relevant creative in real time, supported by fallback and manual override options to ensure brand-safe delivery.

The campaign has been developed with a strict privacy-first approach. All visual data is processed securely on-site, with no facial recognition, no personal identifiers and no recording or storage of imagery, and only anonymised numerical data is used to trigger creative outputs.

By turning a public location like Piccadilly Circus into a responsive digital installation, Samsung shows how AI-enabled technology can adapt to real life.

Donna Buckingham, Head of Account Management, Cheil UK, said: “Turning the live mood of London into real-time creative on the most iconic screen in Europe is a rare creative feat. This work shows Samsung’s belief that technology should adapt to people, brought to life through data, AI and pure craft.”

Amy Campbell, Director of Corporate Marketing, Samsung Electronics UK, added: “London never feels the same from one day to the next, and neither do we. Some days we’re full of energy, others we need a bit of help to keep life moving. This experience captures that feeling in a relatable way and shows how Samsung’s AI-enabled ecosystem can support people in those everyday moments. It’s technology that understands the ebb and flow of real life.”
