Information-presentation structure with visible record of color-changed print area at impact location
First Claim
1. An information-presentation structure comprising:
- an object-impact structure having an exposed surface for being impacted by an object during an activity, the object-impact structure comprising a variable-color region which extends to the exposed surface at a surface zone and normally appears along it largely as a principal color during the activity, an impact-dependent portion of the variable-color region responding to the object impacting the surface zone at an impact-dependent object-contact area spanning where the object contacts the surface zone by temporarily appearing along an impact-dependent print area of the surface zone largely as changed color materially different from the principal color if the impact meets threshold impact criteria, the print area at least partly encompassing, at least mostly outwardly conforming largely to, and being largely concentric with the object-contact area;
object-tracking apparatus for tracking movement of the object over the exposed surface and for providing a tracking impact signal when the object impacts the surface zone according to the tracking; and
an image-generating system responsive to at least the impact signal for generating a print-area vicinity image comprising an image of the print area and adjacent area of the exposed surface.

Abstract
A variable-color region (106) of an information-presentation structure extends to an exposed surface (102) at a surface zone (112) and normally appears along it as a principal color. An impact-dependent portion (138) of the variable-color region responds to an object (104) impacting the zone at an object-contact area (116) by temporarily appearing along a closely matching print area (118) of the zone as changed color materially different from the principal color if the impact meets threshold impact criteria. Object-tracking apparatus (808) tracks movement of the object over the surface and provides an image-causing tracking impact signal when the object impacts the zone according to the tracking. An image-generating system (802, 842, 1152, or 1182) responds to at least the impact signal by generating a print-area vicinity image consisting of an image of the print area and adjacent area of the surface.
