“…With regard to size, we learned from Typhlex that the device should fit a small size to avoid re-gripping [40], a general conclusion found by other DUI researchers [58,61,63]. We also learned that grooves work as a tactile indication of bendable areas, guiding blind users to locate bendable areas [39], in addition to providing strain release for easier bending [41].…”

“…Deformable devices are those that allow users to physically manipulate their shapes as a form of input, by bending, twisting or deforming them [3,41]. The manual deformation forms a curvature on the device for the purpose of triggering a software action and it is generally called a bend gesture [59].…”

“…Considering deformation is a tactile form of input, and blind users solely rely on non-visual feedback, such as tactile cues and audio, Ernst et al [41] proposed deformation could potentially benefit blind users. Ernst and Girouard [40] developed a deformable device the size of an iPhone 6 able to recognize bend gestures.…”

“…[interactions]", supporting the findings from Schwesig et al [84], who found deformation gestures are quick to learn. Additionally, they found participants considered bend gestures a more tactile form of interaction, which could improve the accessibility of smartphones [41], and might be more forgiving for those who also have physical disabilities and hand tremors [40].…”

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.
