Upcoming mobile devices will have flexible displays, allowing us to explore alternate forms of user authentication. On flexible displays, users can interact with the device by deforming the surface of the display through bending. In this paper, we present Bend Passwords, a new type of user authentication that uses bend gestures as its input modality. We ran three user studies to evaluate the usability and security of Bend Passwords and compared it to PINs on a mobile phone. Our first two… 

Bend Passwords on BendyPass: A User Authentication Method for People with Vision Impairment

Bend passwords entered on BendyPass provide a tactile method for user authentication, designed to reduce the vulnerability to attackers and help people with vision impairment to better protect their personal information.

Bend or PIN: Studying Bend Password Authentication with People with Vision Impairment

Findings show bend passwords have learnability and memorability potential as a tactile authentication method for people with vision impairment, and could be faster to enter than PINs, however, BendyPass still has limitations relating to security and usability.

Understanding Authentication Method Use on Mobile Devices by People with Vision Impairment

Most use familiar names and numbers to create memorable passwords, the majority consider fingerprint to be the most secure and accessible user authentication method and PINs the least secure user authentication methods, and insights for designing better authentication methods for people with vision impairment are provided.

Deformable User Interfaces: Using Flexible Electronics for Human Computer Interaction

This work introduces the research on deformable user interfaces by discussing bend gestures as a source of input, presenting the process to rapidly prototype flexible devices, and demonstrating three deformableuser interfaces: bend passwords, bend for mobile games, and bend for vision impaired users.

Vibration-Based Pattern Password Approach for Visually Impaired People

This paper exploits the haptic technology by introducing a vibration-based pattern password approach in which the vibration feedback plays an important role, and shows that the vibration pulses feedback is usable and resistant to shoulder-surfing attacks.

3D-Auth: Two-Factor Authentication with Personalized 3D-Printed Items

3D-Auth is a new concept of two-factor authentication based on customizable 3D-printed items that combine two authentication factors in one object that can be recognized by a capacitive touchscreen.

Effects of Bend Gesture Training on Learnability and Memorability in a Mobile Game

A novel deformable smartphone case that detects bend gestures at its corners and sides is built, and PaperNinja, a mobile game that uses bends as input is created, suggesting that players can learn bend gestures by discovery and training is not essential.

Fabrication of Nāmya: A Bend and Touch-Sensitive Flexible Smartphone-Sized Prototype

In human-computer interaction research, prototypes allow for communicating design ideas and conducting early user studies to understand user experience without developing the actual product. For

Understanding the Design Space of Embodied Passwords based on Muscle Memory

It is found that a movement space of 200 mm × 200 mm is preferred; each context has a perceived level of safety, which—together with the affordances and link to familiarity—influences how the password is performed.
