ABSTRACT:
An active keyboard for handheld electronic devices which allows the user of the device to support the device and enter text and data while using only one hand. The device has a housing, a display, a processor, a memory, a selection device, and at least four keys. When the handheld device is gripped the keys underlay the tips of the user's fingers and the selection device underlays the user's thumb. The software outputs a grid design to the display showing several columns of values. The user highlights a set of four values using the selection device and those values are assigned to the keys. Pressing a key enters the values assigned to that key into the text area of the display or if the value represents a mode of operation, runs the program controlling that mode.
