The present invention provides a system and method for dividing patent claims into segments for display. One embodiment, termed PORTAPAVE\u2122, achieves this interlocking via an array of uniquely configured two-sectioned pavers. The portable electronic device may be operatively coupled to the head-mounted device such that the portable electronic device and head mounted device can communicate and operate with one another. The second recessed surface area extends from the second main surface, includes a closest point closest to the first main surface, and includes an extension part that extends outward of the closest point and toward the second main surface.
