In 2016, Singtel made some major upgrades to their 4G mobile network. To demonstrate its speed and reliability, we put it through a series of very unique tests where a second or two could prove disastrous. Three individuals: a national fencer, a stunt driver and an arcade enthusiast, were challenged to execute three precision stunts – with the mobile network over their eyes. At the heart of Data ExStream is the Data Optic Gear: A custom-built visor that houses two mobile phones over the individuals’ eyes. One phone uses its camera to video capture and stream, the other phone receives the visual feed via Singtel 4G. Any delay in transmission would mean a slow reaction by the individual and therefore, a failed test.
