Free-Form Gestures for Access Authentication on Smart Phones and Tablets (image) Rutgers University Share Print E-Mail Caption Researchers studied the practicality of using free-form gestures for access authentication on smart phones and tablets. With the ability to create any shape in any size and location on the screen, the gestures had an inherent appeal as passwords. Since users create them without following a template, the researchers predicted these gestures would allow for greater complexity than grid-based gestures offer.
