A method for operating a device includes: detecting, within a specified period of time, two sets of touches on a touch screen of the device, wherein each set of touches comprises concurrent touches by two points of contact (610), determining that vibro-acoustic effects of at least one of the concurrent touches match a vibro-acoustic effects profile among a plurality of vibro-acoustic effects profiles stored in the device (620), and initiating a pre-specified action on the device in response to the detection of the two sets of touches within the specified period of time (630). |
