The U.S. Patent and Trademark Office on Thursday published an Apple patent application detailing a full-function "smart dock" that continually listens for cues to activate and communicate with the voice recognition functions of docked devices, like the iPhone and iPad.
Apple's "Smart dock for activating a voice recognition mode of a portable electronic device" filing clearly describes an iOS device accessory unlike anything the company has manufactured. Like third-party peripherals, Apple's proposed dock can include a speaker, microphone and built-in screen, but goes further by allowing access to the Siri virtual assistant.
Currently, Apple's only docking solutions for both the iPhone and iPad are limited to charging and line-out audio. In contrast, the proposed dock would have a screen, tactile controls or a touch panel with which a user can interface. Other embodiments include a scroll wheel, buttons and other manual controls.
Instead of carrying Siri onboard, the dock would be mostly headless until an iPhone or iPad was operatively coupled to the unit. Basic functionality like a clock and radio are provided, but voice recognition and heavy processing are accomplished by the iOS device.
Basically, the dock listens for a specific prompt, recognizes an activation request by the user, relays commands to the docked iPhone and executes any operations returned by the device. Examples could be playing a song or facilitating communication between the user and Siri.
In operation, a user would perform an initial setup that would include assigning an audio prompt, such as a spoken word or hand clap, that will be used to activate the unit and its services. For example, a user may want to set the prompt as a finger snap. When in listening mode, if the dock "hears" a finger snap, it will activate the iPhone's voice recognition feature.
By setting listening thresholds, the dock can selectively filter out ambient noise while still allowing a user to operate their device remotely using only audio cues. Since the system relies primarily on audio input, an effective limiter must be implemented to ignore responses by Siri. In these scenarios, the dock would deactivate listening mode during voice recognition operations.
Internal components include a wireless communications module for accessing off-site databases and Internet assets like webpages or cloud storage. If, for example, a user wanted to change their schedule for the day, they could initiate Siri via the always-listening dock and modify a calendar stored in iCloud.
In addition to the built-in hardware, the dock can also be fitted with add-ons like a removable hard drive, environmental sensors, a GPS module and more. Some embodiments allow for the dock and iOS device to be paired but uncoupled, meaning the dock would transform into a sort of smart wireless speaker system.
Finally, users can force the dock to deactivate Siri by issuing a verbal command or other audio input. Alternatively, the dock itself can time out Siri voice recognition and put the iOS device to sleep after a predetermined time period. There is also a provision for wireless inductive charging.
Apple's smart dock patent application was first filed for in May 2012 and credits Scott Krueger, Jesse Dorogusker and Erik Wang as its inventors.
