Apple reveals plans to improve voice control on its iOS devices using contextually defined commands chosen by users, via a recent patent filing. Also, Apple recently purchased the iOS "personal assistant" app creator Siri, suggesting it had plans to improve the voice control functionality in iPhones, iPads, and the iPod Touch.
This patent appears to utilize some aspects of Siri's interface, applying them to each selected apps individually.
"By using contextual voice commands, a user can execute desired operations faster than by navigating through a set of nested menu items," the filing reads. "Also, contextual voice commands can be used to teach the device to accurately predict the intent of the user from a single voice command. Further, contextual voice commands can be used to vary the manner in which the user provides the voice input based on the context of the device being used."
Maybe one button will be too much for the iPad 3 when this gets implemented!
