Sysco AV turned to Delta to develop a variety of technology solutions that couldn't be bought off-the-shelf. We created touch-sensitive guitar fretboards and piano keyboards, allowing visitors to scroll through on-screen content in a fun and engaging way. We developed a rotary interface, similar to a radio dial, to work with other software interactives. We also designed and produced reader pads for the exhibition-wide RFID system, which allows visitors to personalise their visit using their entry ticket. Finally, we developed and produced the electronics for around 200 headphone volume control units, as no commercially available product fully met the needs of the project.
