ABSTRACT
With modern smartphones, users can access to secured applications such as e-banking, booking flight tickets, and etc. Using these applications in public areas is risky since it is easy for people around the user to peep at the password input. One way to enhance security is to enter the passwords inside one's pocket or purse in an eyes-free manner. In this paper, we designed, prototyped and evaluated four eyes-free password entry methods (Number Pad, Wheel, Stroke, and Scroll) on the iPhone. Our experiment results showed the comparative advantages of the Wheel (Figure 1b) and Stroke (Figure 1c) methods. In addition to that, guidelines and implications for designing eyes-free password entry methods are also discussed.

Virtual Buttons for Eyes-Free Interaction: A Study
Human-Computer Interaction – INTERACT 2015AbstractThe touch screen of mobile devices, such as smart phones and tablets, is their primary input mechanism. While designed to be used in conjunction with its output capabilities, eyes-free interaction is also possible and useful on touch screens. ...
Understanding back-to-front pinching for eyes-free mobile touch input
MobileHCI '16: Proceedings of the 18th International Conference on Human-Computer Interaction with Mobile Devices and ServicesUsing a smartphone touchscreen to control apps mirrored to a distant display is hard, since the user cannot see where she is touching while looking at the distant screen. Tactile landmarks at the back of the phone can mitigate this problem, especially ...
System-Assigned Passwords: The Disadvantages of the Strict Password Management Policies
After Morris and Thompson wrote the first paper on password security in 1979, strict password policies have been enforced to make sure users follow the rules on passwords. Many such policies require users to select and use a system-generated password. The ...
