Quester is new heavy-duty truck range developed for Asia and other growth markets. The launch event was part of a broad campaign aimed at transport industry professionals on the major Asian markets.
At the event guests speaking eight different languages gathered. In addition to the unveiling of the truck, the event featured an exhibit where guests could explore more than 40 screens of different shapes and sizes with digital content with all there is to know about Quester.
Every guest received a RFID key fob that they could use to translate screen content into their own language. At times UD Trucks experts used the screens in short talks about specific features and benefits. By holding up a special black key fob they started a slideshow supporting their presentation. These slideshows were also available in eight languages.
Every screen was powered by a Raspberry Pi microcomputer running custom built software based on the open source c++ creative coding system OpenFrameworks. Each computer was connected to an Arduino based 125KHz RFID reader linked via a converter shield.
The main application starts automatically when the computer boots up and shows content for the default language. Content can be both still images and movies. Different RFID key fobs can then trigger a language change, which then reverts to the default language after a set timeout. Since the computers where tightly integrated inside the different exhibitions walls and we really couldn’t access any keyboard or mouse, we created specific settings key fobs that can set all system settings such as screen rotation or default language.
A separate tag registration application was created to simplify setup of the 1200 key fobs that needed to be registered to trigger a specific language or functionality in the main application.
