Hyundai's Vision Pulse: keyring tags make kids visible to school buses — Cannes Bronze
Hyundai/Kia's UWB safety tag rides on a child's backpack keyring and doubles as a night light, so drivers see kids in blind spots — Cannes Design Bronze 2026.
Hyundai Motor Group · Kia
What it had to solve
Hyundai Motor and Kia had ultra-wideband (UWB) technology — the radio system behind their digital car keys — that can locate objects within about 10 centimeters over a range of roughly 100 meters, even in crowded intersections. Children around kindergarten shuttle buses are small and easy to miss in a driver's blind spots, but a safety tag is useless if a child forgets to carry it or forgets to charge it.
How it works
Vision Pulse started with a technical asset and a human problem. Hyundai Motor Group had ultra-wideband (UWB) radio technology, the same low-power, high-precision system behind its digital car keys, which can identify the location of nearby objects within about 10 centimeters at a range of roughly 100 meters even in busy urban intersections. The problem was that kindergarten children are small, unpredictable and often invisible to a shuttle bus driver; cameras and mirrors leave blind spots around the vehicle.
The system pairs a UWB module on the bus with small UWB tags carried by children and other road users; when the vehicle detects a possible collision risk, it warns the driver in real time. Independent Korean agency Paulus led the creative and design work with UWB partner Wearby, and its core insight was about adoption: children had to carry the tag all day and recharge it regularly, which sounds like a chore. So the agency designed the tag as a keyring for the school bag by day and a mood light by night, making charging a natural part of the child's bedtime routine.
The campaign film documented the technology in a pilot on kindergarten shuttle buses, and the jury at Cannes Lions 2026 gave it a Bronze Lion in Design: Use of Emerging Technology, valuing both the practical safety application and the way it connected advanced technology to the automaker's existing digital-key capability. Earlier in 2026 it had won Bronze in Innovation at Spikes Asia and Merits at The One Show.
Hyundai and Kia treated Vision Pulse as a platform, not a one-off ad. Since 2025 they have applied the same UWB collision-prevention system to production lines at Kia's purpose-built vehicle conversion center in Hwaseong, where it helps prevent collisions between forklifts and workers, and Hyundai agreed in October 2025 to test it at Busan Port terminals and logistics sites.
Why it lands
- It repurposed an existing corporate asset — UWB digital-key technology — into a social-safety application instead of inventing new hardware.
- The design removes the two failure points of safety wearables: carrying is natural because keyrings on backpacks are routine, and charging happens because the tag is a bedtime night light.
- A real deployment on kindergarten shuttle buses, documented on film, let the jury and public see the technology working rather than just imagining it.
- The same platform then scaled into industrial safety, from Kia's Hwaseong conversion center to Busan Port, showing one idea solving similar blind-spot problems across settings.
What it did
The work won a Bronze Lion in Design: Use of Emerging Technology at Cannes Lions 2026, after earlier winning Bronze in Innovation at Spikes Asia 2026 and Merits at The One Show 2026. The jury recognized it for applying emerging technology to a real safety problem and for linking the system to the companies' existing digital-key technology. Hyundai and Kia also moved the same UWB system beyond roads into industrial sites — production lines at Kia's conversion center in Hwaseong and port-terminal trials agreed with the Busan Port Authority in October 2025.
What you can take
A safety device only works if people actually carry it: Paulus built on a behavior children already have — keyrings on school bags — and folded the charging routine into bedtime.
Since then
After the Cannes Bronze in June 2026, Hyundai and Kia continued positioning Vision Pulse as an evolution of automotive perception rather than a standalone feature, testing it in industrial environments since 2025: Kia's purpose-built vehicle conversion center in Hwaseong uses it to prevent forklift-worker collisions, and a Hyundai agreement with the Busan Port Authority from October 2025 covers terminal and logistics trials. The campaign also gave Paulus its first Cannes Lions win as an independent agency.
