6. In a Cartesian coordinate system, a point whose both vertical and horizontal coordinates are integers is called an integer point. The number of integer points $(x, y)$ that satisfy the inequality $(|x|-1)^{2}+(|y|-1)^{2}<2$ is $\qquad$ .
6. 16 Detailed Explanation: From $(|x|-1)^{2}+(|y|-1)^{2}<2$, we can deduce that $(|x|-1,|y|-1)$ are $(0,0),(0,1),(0,-1)$, $(1,0),(-1,0)$, thus yielding 16 pairs of $(x, y)$.
