Abstract: A portable information handling system having a display on each of opposing rotationally coupled housing portions monitors for objects disposed on a display and takes corrective action if the housing portions rotate to a closed position that impacts the object on an opposing display. For instance, a keyboard or stylus placed on one display is detected by the touchscreen, by Hall sensors, by IR sensors and or other sensors. The rotational position and angular velocity of the housing portions are tracked and analyzed to take corrective action if the housing portions will reach a closed position in less than a predetermined time. The corrective action may include visual and audible warnings and/or braking at a hinge that works against hinge rotation to slow or stop impact by the object and display.
