Touchgazepath: Multimodal interaction with touch and gaze path for secure yet efficient pin entry
2019 International Conference on Multimodal Interaction, 2019•dl.acm.org
We present TouchGazePath, a multimodal method for entering personal identification
numbers (PINs). Using a touch-sensitive display showing a virtual keypad, the user initiates
input with a touch at any location, glances with their eye gaze on the keys bearing the PIN
numbers, then terminates input by lifting their finger. TouchGazePath is not susceptible to
security attacks, such as shoulder surfing, thermal attacks, or smudge attacks. In a user study
with 18 participants, TouchGazePath was compared with the traditional Touch-Only method …

We present TouchGazePath, a multimodal method for entering personal identification numbers (PINs). Using a touch-sensitive display showing a virtual keypad, the user initiates input with a touch at any location, glances with their eye gaze on the keys bearing the PIN numbers, then terminates input by lifting their finger. TouchGazePath is not susceptible to security attacks, such as shoulder surfing, thermal attacks, or smudge attacks. In a user study with 18 participants, TouchGazePath was compared with the traditional Touch-Only method and the multimodal Touch+Gaze method, the latter using eye gaze for targeting and touch for selection. The average time to enter a PIN with TouchGazePath was 3.3 s. This was not as fast as Touch-Only (as expected), but was about twice as fast the Touch+Gaze. TouchGazePath was also more accurate than Touch+Gaze. TouchGazePath had high user ratings as a secure PIN input method and was the preferred PIN input method for 11 of 18 participants.
