Authentication through passwords in public spaces (such as in ATMs) is susceptible to simple observation attacks, such as shoulder surfing, which can result in the password being compromised and ultimately the exposure of users to fraud and theft. Haptic technology, which can present information non-visually to users, offers a potential solution to this problem through the creation of tactile passwords. Situated in this space, this paper presents the design and initial evaluation of a novel haptic device, the haptic wheel, which displays tactons, or structured tactile messages, to enable password entry. It describes this device and the tactile passwords it supports in detail before presenting two short user studies. The results of these reveal that the chosen tactons are easily identifiable and that password entry times are significantly improved compared to previous systems based on haptic authentication.
