“…Different than what was previously found [68], bend passwords were faster to confirm (M=15.6s, Md=14s, SD=4.19s) than PINs (M=20.6s, Md=17.5s, SD=9.43s) (Z= -2.27, p = .01). Bend passwords were faster to confirm than in prior work with sighted participants (15.6s vs 19s), while PINs were slower to confirm (20.6s vs 6s) [66]. However, participants had more incorrect attempts to confirm their bend passwords than to confirm their PINs for the three times.…”

“…PINs were slower to confirm (16.8s vs 5s) [66]. Not considering failed confirmation attempts due to prototype errors, participants made slightly more incorrect rehearsal attempts for bend passwords than for PINs, but the difference was not significant (n.s.).…”

“…Participants took less time to rehearse their passwords than to confirm them. Participants took significantly less time to rehearse their PINs than to confirm them (Z= -2.97, p = .001), as found by Maqsood [66].…”

“…The researchers chose to use PINs in the comparison "because they are the most commonly used authentication mechanism on mobile devices" [67]. The researchers found that bend passwords are as easy to memorize as PINs, as "they have an advantage over PINs because they require a repetition of movements, which becomes an automatic and unconscious action, or part of what is called muscle memory" [66].…”

“…inside its left side, to give haptic feedback for the user that a gesture was recognized by the system and a push-button on its right side, to allow the user to delete the previous gesture entered or confirm the password (Figure 16). Our prototype has a button embedded, because Maqsood et al [66] reported challenges with having it decoupled from the flexible prototype, which required users to shift their attention from the device to the control panel where the buttons were.…”

Bend Passwords for People with Vision Impairment

Passwords help people avoid unauthorized access to their personal devices but are not without challenges, like memorability and shoulder surfing attacks. Little is known about how people with vision impairment assure their digital security in mobile contexts. We conducted an online survey with 325 people who are blind or have low vision and found they are concerned about entering passwords in public because of the risk of others observing their passwords. We also found PINs, commonly required on smartphones, are considered insecure and poorly accessible. To solve those issues, we investigated the usability of bend passwords, a recently proposed method for authentication that uses a combination of predefined bend gestures performed on a flexible device. We designed a new deformable prototype and ran a user study with 16 vision-impaired participants, finding that bend passwords are as easy to learn and memorize as PINs, but are faster to enter than PINs.

Passwords help people avoid unauthorized access to their personal devices but are not without challenges, like memorability and shoulder surfing attacks. Little is known about how people with vision impairment assure their digital security in mobile contexts. We conducted an online survey to understand their strategies to remember passwords, their perceptions of authentication methods and their self-assessed ability to keep their digital information safe. We collected answers from 325 people who are blind or have low vision from 12 countries and found: 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 method. This paper presents our survey results and provides insights for designing better authentication methods for people with vision impairment.

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 investigating deformation-based interaction, functional prototyping becomes challenging due to the unavailability of commercial platforms and the marginal availability of flexible electronic components. During functional prototyping, incurred time and cost are essential factors that further depend on the ease of stiffness customization, reproduction, and upgrade. To offer these advantages, this work presents the fabrication workflow of Nāmya, a smartphone-sized flexible prototype that can detect bend gestures and touch-based inputs using off-the-shelf sensors and flexible materials. This do-it-yourself (DIY) approach to fabricating deformable prototypes focuses on addressing the challenges of selecting flexible material, type of sensor, and sensor positions. We also demonstrate that the proposed use of a flexible three-dimensional- (3D-) printed internal structure with sensor pockets and the one-part silicone cast allows the development of robust deformable prototypes. This fabrication process offers the opportunity to easily customize device stiffness, reproduce prototypes with similar physical properties, and upgrade existing prototypes.
