SRI International
In December 2007, SRI launched a spin-off company, Siri Inc., which Apple acquired in April 2010. In October 2011, Apple announced the Siri personal assistant as an integrated feature of the Apple iPhone 4S. Siri's technology was born from SRI's work on the DARPA-funded CALO project, described by SRI as the largest artificial intelligence project ever launched. Siri was co-founded in December 2007 by Dag Kittlaus (CEO), Adam Cheyer (vice president, engineering), and Tom Gruber (CTO/vice president, design), together with Norman Winarsky (vice president of SRI Ventures). Investors included Menlo Ventures and Morgenthaler Ventures.
Apple Remote
The Siri Remote was launched with the 4th Generation Apple TV in 2015. It uses both IR and Bluetooth to communicate with the Apple TV. The remote has a glass trackpad, dual microphones, 5 buttons for Menu, Home, Siri and Play/Pause, Volume up and down as 1 button and is the size of 2 buttons. Additionally it has an accelerometer (IMU) and a gyroscope which allows the remote to be used as a gaming controller for tvOS apps and games. The remote (unlike previous generations) uses a built-in rechargeable Lithium Polymer Battery that is charged through the lightning port at the bottom of the remote. The Siri Remote is known as the Apple TV Remote in places that don't support Siri.
