San Francisco: Apple has been granted a patent for an iPhone 'smart dock' that could have personal assistant Siri and a wireless charger built in. According to the patent, Apple is planning a 'smart dock' for activating voice recognition mode of a portable electronic device, The Verge reported on Thursday. The 'dock' could recognise when an iPhone is placed in it and activate a microphone to allow users to give voice commands to control the phone. The patent which also covers wireless charging describes the dock as simple connectors with a microphone and speaker or it could be like a full-fledged miniature computer with buttons and displays, the report added. Apple may be working on this technology which could be seen in the upcoming iPhone 8.
