Method and system for activating different interactive functions using different types of finger contacts

摘要

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.
