Designs and Algorithms to Map Eye Tracking Data with Dynamic Multielement Moving Objects

Figure 8

Example of a multielement object (black and red) represented using dynamic AOIs (green solid and dotted lines surrounding the object): the shape created when using dotted green lines represents a tightly fitted AOI, and the shape created when using solid green lines represents a slightly enlarged AOI with a buffer of 40 pixels.

(a) Convex AOI

(b) Rectangular AOI
