Lasta Digital Wheel of Treats at Bingo Shopping Center, Sarajevo
A gesture-controlled wheel of confectionery prizes on digital signage at Bingo Shopping Center, Sarajevo
The Challenge
Confectionery is an impulse category: the decision is made in the aisle, and a poster rarely triggers it. Lasta wanted an in-centre activation at Bingo Shopping Center in Sarajevo that would stop family shoppers, sit naturally next to the product, and work without a shared touchscreen in a food environment.
The Solution
TapGest built a Digital Wheel of Treats on the centre's digital signage — a branded wheel whose segments are Lasta's own products: boxes of chocolates, bags of candy and baked goods. Spinning it is the whole mechanic, and the prize is something the shopper can taste the same day.
The Visitor Experience
Shoppers walking through the centre see the wheel turning on the screen. Stepping in front of it, they spin it with a hand movement — no touching, no app, no registration. Because the segments are recognisable products rather than abstract prize tiers, people understand what is at stake before they play, and children in particular pull their parents over to try.
Implementation
The application uses camera-based hand tracking on the existing in-centre signage. Segment artwork, prize weighting and the on-screen result messaging were produced specifically for Lasta's range and the Bingo Shopping Center placement.
Technology Setup
The application runs on the in-centre digital signage with a camera pointed at the space in front of the screen. That camera image is the only input: it detects that someone has stepped up and follows their hand, so nothing is touched, worn or scanned. Because Lasta's prizes are physical products, the wheel segments were built from the actual product range and the on-screen result is what the promoter hands over at the stand.
Results
The wheel gave Lasta a repeatable, staffed-optional activation in a high-traffic centre, with prize fulfilment handled at the stand next to the screen. We do not publish participation or sales figures for this campaign.
Frequently asked questions
Where did the Lasta Wheel of Treats run?
At Bingo Shopping Center in Sarajevo, Bosnia and Herzegovina, on the centre's digital signage.
How do shoppers spin the wheel?
With a hand gesture in front of the display. The interaction is camera-based and touchless — nothing to tap and no app to install.
What could shoppers win?
Products from Lasta's own range — boxes of chocolates, bags of candy and baked goods — which is why the wheel segments show the actual products rather than abstract prize tiers.
Was a promoter needed at the screen?
The game itself runs unattended, but prizes were handed over at the stand next to the screen, so staffing was tied to fulfilment rather than to explaining the interaction.
