Handheld electronics device having ergonomic features

A handheld electronics device having ergonomic features that assist a user who holds the electronics device, the electronics device comprising:

• a housing that is narrower at a middle gripping region than at a top section and a bottom section at either side of the gripping region, the housing having:
• a front surface;
• a back surface;
• lateral surfaces;
• rounded corners where the lateral surfaces meet the back surface and where the lateral surfaces meet the front surface;
• a longitudinal depression formed in the back surface, the depression having a peripheral edge distant from the lateral surfaces and is substantially at a midline of the back surface, the depression being adapted for engaging a portion of a hand of the user when the user holds the electronics device;
• a keypad structure positioned on the front surface at the middle gripping region;
• and
• a screen of a display device positioned at the top section.

A handheld computer having ergonomic features that assist a user who holds the computer, the computer comprising:

• a housing that is narrower at a middle gripping region than at a top section and a bottom section at either side of the gripping region, the housing having:
• a front surface;
• a back surface;
• lateral surfaces;
• rounded corners where the lateral surfaces meet the back surface;
• a longitudinal depression formed in the back surface, the depression having a peripheral edge distant from the lateral surfaces and is substantially at a midline of the back surface for engaging a portion of a hand of the user when the user holds the electronics device, the longitudinal depression having a generally oblong shape having a major axis parallel to the longitudinal axis of the housing;
• a keypad structure positioned on the front surface at the middle gripping region such that a force applied to depress a key of the keypad structure is directed generally toward the longitudinal depression, the keypad structure defining a first line that is normal to the keypad structure and extends away from the keypad structure;
• and
• a screen of a display device positioned at the top section, the screen defining a second line that is normal to the screen and extends away from the screen, wherein the first line and the second line intersect.

A handheld electronics device having ergonomic features that assist a user who holds the electronics device and that further has features that assist the user in cleaning the electronics device, the electronics device comprising:

• a housing that is narrower at a middle gripping region than at a top section and a bottom section at either side of the gripping region, the housing having:
• a front surface;
• a back surface;
• lateral surfaces;
• rounded corners where the lateral surfaces meet the back surface;
• a depression formed in the back surface substantially at a midline of the back surface for engaging a portion of a hand of the user when the user holds the electronics device;
• a keypad structure positioned on the front surface at the middle gripping region, the keypad structure defining a first line that is normal to the keypad structure and extends away from the keypad structure;
• a touch sensitive screen of a display device positioned at the top section, wherein the touch sensitivity of the screen can be selectively disabled without disabling the display device to enable the display device to be cleaned without causing the screen to react to pressure applied during cleaning, the touch sensitive screen defining a second line that is normal to the touch sensitive screen and extends away from the touch sensitive screen, wherein the first line and the second line intersect;
• and
• a selectively removable bezel positioned over the keypad structure, the bezel having openings through which keys of the keypad structure extend when the bezel is positioned over the keypad structure, the bezel being removable to expose the keypad structure and enable the keypad structure to be cleaned.
