The usage of interactive public displays has increased including the number of sensitive applications and, hence, the demand for user authentication methods.
We implement a calibration-free authentication method for situated displays based on saccadic eye movements which tackles the drawbacks of gaze-based authentications: they tend to be slow and prone to errors.
Figure 1: Interface of EyeLogin.
Figure 2: Interface of CueAuth .
In our implementation, we leverage the quick nature of saccadic eye movements between fixations from the center to a digit in the interface (see Figure 1). Fixating a digit and returning to the center triggers a digit entry.
Additionally, we implement CueAuth , an authentication method based on smooth pursuit eye movements: a digit is entered by following a moving digit stimuli in the interface (See Figure 2).
In a user study (n=10), we compare our new method with CueAuth from Khamis et al. .
Our evaluation shows that our method EyeLogin outperforms the baseline CueAuth in terms of accuracy and entry time.
