Consisting of a tiny circular receiver, users download an app onto their mobile device and use WiFi to communicate with it. Commands from the phone/tablet and then converted into infrared signals that are sent out to the appropriate devices depending on the instruction. I.e. If you choose to listen to music, it will send instructions to your HiFi system, while if you want to watch a movie, your TV and Blu-ray player will receive commands instead. No more need to have multiple remote controls or even having to point to the right direction.
