Motivation

The customer aimed to enhance fan engagement during football matches by introducing an interactive auction system. This system needed to be seamlessly integrated into the existing digital infrastructure and provide a high-quality user experience across all devices, including the stadium’s large-scale jumbotron.

Main Challenges

Challenge 1
Cross-Device Synchronization

The auction required real-time synchronization across thousands of personal devices and the stadium jumbotron, ensuring all participants had the same experience. Azati proposed leveraging WebSocket technology for real-time communication to synchronize all devices and the jumbotron instantly, ensuring seamless interaction across platforms.

Challenge 2
Pixel-Perfect Display

The interface needed to support various screen resolutions, including the unique 1,120 × 4,648 resolution of the stadium’s jumbotron, while maintaining flawless visual quality. Azati recommended implementing adaptive image scaling and responsive design techniques to ensure pixel-perfect quality across devices, especially the large jumbotron screen.

Key Features

  • Real-Time Interactive Auctions: Live auctions with dynamic pricing and instant participation.
  • Cross-Device Compatibility: A seamless experience on mobile devices, desktops, and the stadium jumbotron.
