Abstract:
An electronic device includes a touch-sensitive surface, for example a touch pad or touch screen. The user physically interacts with the touch-sensitive surface, producing touch events. The resulting interface actions taken depend at least in part on the touch type. The type of touch is determined in part based on vibro-acoustic data and touch data produced by the touch event.
Abstract:
A method activates different interactive functions based on a classification of vibro-acoustic signals resulting from touch events with finger parts of a user. A primary function is trigger when an interactive element on a touch screen is touched with a finger tip of the user. An auxiliary function is launched when the interactive element is touched with a knuckle or fingernail of the user. The touch events result in generating the vibro-acoustic signals. The vibro-acoustic signals are classified and used to distinguish what finger part was used based on the classification of the vibro-acoustic signals.
Abstract:
An input tool includes a body in the form of a stylus with plurality of vibro-acoustically distinct regions. The vibro-acoustically distinct regions produce vibro-acoustic responses when the regions touch the surface of the touch screen. The vibro-acoustic responses are used in a computing device to detect what region of the input tool was used.
