Abstract
A user's signature may be decomposed into one or more components. The components may be described using one or more control points. A user may sign with their eyes by focusing their gaze on a set of these control points that make up the signature. If the user's gaze is within a threshold distance from a control point the signature is validated. Moreover, by modifying the control points based upon the actual gaze location (which is within the threshold distance), the signature may be slightly modified. For example, the signature may be decomposed into one or more components as Bezier curves and the user may be asked to focus on each control point of each of the one or more Bezier curves. Modifying the control points of a Bezier curve slightly still produces a smooth curve, but introduces natural variations.
