Systems and methods for identifying user-operated features of input interfaces obfuscating user navigation

A method performed by a data processing system of obfuscating a user target actuation, the method comprising:

• concurrently displaying a first plurality of targets including a first target, a second target, a third target, a fourth target, and a fifth target;
• presenting, at a first time during a first period of time that a current user target remains the first target, a discriminatory signal to a user indicating a first visual indication displayed at the first time is for the current user target, wherein the discriminatory signal includes one of a haptic signal generated by a device in physical contact with the user, an audio signal, and a modified image, and wherein the audio signal and the modified image are discernable within a predetermined range of the system to prevent an observer outside of the predetermined range of the system from discerning the audio signal and the modified image;
• displaying, at the first time, the first visual indication in association with the current user target;
• displaying a second visual indication of a first current distractor target at the second target during the first period of time;
• moving a third visual indication of the current user target to the third target at a second time after the first period of time to reflect a change of the current user target to the third target in response to a first user input event for navigation of a current user target;
• actuating the current user target at a third time after the second time in response to a second user input for actuation of the current user target;
• moving the second visual indication to the fourth target at a fourth time at or after the second time;
• and
• moving the second visual indication to the fifth target at a fifth time after the third time and before the second time.

A computer-readable storage medium on which are stored instructions that, when executed, cause a processor of a programmable device to perform functions of:

• concurrently displaying a first plurality of targets including a first target, a second target, a third target, a fourth target, and a fifth target;
• presenting, at a first time during a first period of time that a current user target remains the first target, a discriminatory signal to a user indicating a first visual indication displayed at the first time is for the current user target, wherein the discriminatory signal includes one of a haptic signal generated by a device in physical contact with the user, an audio signal, and a modified image, and wherein the audio signal and the modified image are discernable within a predetermined range of the system to prevent an observer outside of the predetermined range of the system from discerning the audio signal and the modified image;
• displaying, at the first time, the first visual indication in association with the current user target;
• displaying a second visual indication of a first current distractor target at the second target during the first period of time;
• moving a third visual indication of the current user target to the third target at a second time after the first period of time to reflect a change of the current user target to the third target in response to a first user input event for navigation of a current user target;
• actuating the current user target at a third time after the second time in response to a second user input for actuation of the current user target;
• moving the second visual indication to the fourth target at a fourth time at or after the second time;
• and
• moving the second visual indication to the fifth target at a fifth time after the third time and before the second time.
