POP-UP CARDS FOR EARLY CHILDHOOD LEARNING

Algorithms for Designing Pop-Up Cards

We prove that every simple polygon can be made as a (2D) pop-up card/book that opens to any desired angle between 0 and 360◦. More precisely, given a simple polygon attached to the two walls of the open pop-up, our polynomial-time algorithm subdivides the polygon into a single-degree-of-freedom linkage structure, such that closing the pop-up flattens the linkage without collision. This result s...

From Pop-Up Cards to Coffee-Cup Caustics: The Knight's Visor

As a pedagogical exercise, we derive the shape of a particularly elegant pop-up card design, and show that it connects to a classically studied plane curve that is (among other interpretations) a caustic of a circle.

Using pop-up windows to improve multimedia learning

The aim of the present study is to evaluate the effects on learning of the spatial integration of textual information incorporated in illustrations in the form of pop-up windows which are opened by the user. Three groups of students viewed illustrated texts depicting the functioning of the heart and the replication of the AIDS virus either with textual information presented below the picture, w...

Pop-up book MEMS

We present a design methodology and manufacturing process for the construction of articulated three-dimensional microstructures with features on the micron to centimeter scale. Flexure mechanisms and assembly folds result from the bulk machining and lamination of alternating rigid and compliant layers, similar to rigid-flex printed circuit board construction. Pop-up books and other forms of pap...
