Figure 3. Human Results for Extended 3D Search and Estimated Coverage in 2D and 3D Search.

Figure 3.

(A) Schematic of one trial in the extended 3D search experiment. Participants could not respond absent until they explored a minimum of 40% of the image calculated with a 2.5°-radius UFOV. To help observers keep track of the areas they searched, the computer shaded a 2.5° radius area around each observer’s fixations, which appeared after the observer scrolled to another slice.

(B) Proportion of correct target detection for the normal search and extended search.

(C) Proportion covered with a 2.5° UFOV.

(D) Average search times.

(E) Real and estimated coverage for participants using a 2.5° UFOV.

Error bars are ±SEM. *p < 0.05; ***p < 0.001.
