    摘要: Wireless handheld mobile communication device and keyboard therefore having a keyfield including a plurality of depressible keys arranged in rows that are distributed about a vertical centerline (Vc) of the keyboard. Each of the depressible keys has a top engagement surface of which an upper inboard portion is raised relative a lower outboard portion thereof. The top engagement surface of each of the depressible keys is ramped from the lower outboard portion toward the upper inboard portion. Each top engagement surface is generally crest shaped, with the apex of the crest running generally diagonally across the respective key with the rest of the top engagement surface falling away from the crest toward the upper outboard portion and the lower inboard portion of the key. The top engagement surface of each of the depressible keys terminates at an upper edge thereof in an elevated ridge down from which the balance of the respective top engagement surface slopes.

    摘要: An improved handheld electronic device includes an improved keypad with keys that impart a plurality of different instances of a given physical property. In one embodiment, each key imparts of plurality of different instances of the given physical property, such as by forming each key of a plurality of materials. In another embodiment, each key includes only a single instance of a given physical property, but different keys posses different instances of the same physical property, i.e., certain keys may be formed of a first material, and other keys may be formed of a second, different material.
