Given that P is a point on the ellipse $\frac{x^{2}}{4} + \frac{y^{2}}{3} = 1$, and F$_1$, F$_2$ are the left and right foci of the ellipse respectively. If the radius of the incircle of △PF$_1$F$_2$ is $\frac{1}{2}$, then $\overrightarrow{PF_{1}} \cdot \overrightarrow{PF_{2}}$ equals \_\_\_\_\_\_.
