Abstract: A generator for mobile apps provides an easy to use template for creating multiple apps that all share a coherent navigation system and infrastructure in order that all of the apps function as a network that can be accessed by installing just one of the apps. Multiple users of the generator create their own apps and offer the apps to users of mobile computerized devices. When a user of a mobile device downloads just one of the apps, they are provided with access to the entire network of apps, without having to download and install each of the apps separately. This is particularly useful for location-based apps, content apps, and commerce apps.

Abstract: Depressible home keys built into an overlay for a touch-sensitive keyboard offer rest positions for the fingers of a typist, and recesses in the overlay allow engagement of the touch sensor while providing tactile feedback to the typist when engaging non-home keys. The significant difference in elevation between the recesses and the rest of the overlay prevents accidental engagement of spaces between the keys or of multiple keys at one time. This configuration for touch-sensitive keyboards can be embodied in an overlay for a touch screen or for a tablet computer, as a stand alone keyboard, or as a stand alone keyboard that includes a touch screen that provides multiple sets of characters and/or commands to be used with specific computer programs.

Abstract: A touch screen keyboard in which one of the user's digits maintains contact with the touch screen, sliding across the screen below the keyboard with a magnifying cursor reaching upward from the digit onto the keyboard, enlarging one key at a time. The enlarged key is engaged when the user taps the screen anywhere else with another digit. Alternate configurations use fixed graphical buttons or accelerometer detected tapping for engagement of the enlarged key.

Abstract: A movable semi-rigid strip of depressible keys that overlays a touch screen in order to provide tactile home positions for the fingers. The home row key strip can be easily moved into place over the visual image of the home row when the touch screen's keyboard appears. Anti-slip material on the bottom surface of the key strip keeps it in place at the typist types. An alternate configuration provides tabs on the end of the key strip that create tension on the sides of the touch screen or tablet computer in order to keep the key strip in place over the home row, but allowing the strip to slide quickly to a border region. Other configurations for affixing the key strip include magnets, tracks on the sides of the touch screen, and hinged arms that allow the key strip to move quickly on and off the touch screen.

Abstract: A compact ergonomic keyboard that places a raised input control pad at the center of the keyboard in order to maintain smaller lateral dimensions and prevent inadvertent engagement of the central input control pad. Placed between the left and right sections of the keyboard, said input control pad provides easy implementation of web browser commands, media commands, and direction controls. A raised miniature trackball or raised trackpad for cursor controls is also placed between the left and right sections. An alternate configuration achieves the same benefit by placing the input control pad and the trackball/trackpad at an elevation that is lower than the keys of the left and right sections.

Abstract: A keyboard allowing typists to use approximate QWERTY finger movements on a more compact, collapsible, and portable keyboard. The keyboard size is made more compact by using thin capacitance-responsive surfaces as key switches for the rows above and below the home row. The bottom, space-bar row is also touch-sensitive and is placed on the side of the keyboard facing the typist. The capacitance-responsive surface for the row of keys switches above the home row has a convex profile, and the capacitance-responsive surface for the row of keys switches below the home row has a concave profile, such that the keyboard can fold compactly upon itself. The home row retains depressible key switches in order to provide standard rest positions for the fingers. Characters and commands assigned to the rows above and below the home row are engaged by sliding the fingers over the capacitance-responsive surfaces adjacent to the home row.
