Programmable keypad for sized optimized device

Abstract

Systems and methods are provided that facilitate configuration of a keypad by end users of the portable host device, via employing a mapping component that can map individual keys of the keypad to characters and / or functions predefined by a user (e.g., defined for the host unit via a proprietary application / software). The reconfigurable keypad of the present invention can provide for a one touch access to special characters and / or performance of predetermined functions designated by the user, and thus facilitates performances of customized functions that can be unique to the end users.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] This application is a continuation application of U.S. patent application Ser. No. 10 / 903,760, filed Jul. 30, 2004, entitled “PROGRAMMABLE KEYPAD FOR SIZED OPTIMIZED DEVICE.” The entirety of which application is incorporated herein by reference.TECHNICAL FIELD [0002] The present invention relates to systems and methods of providing an ergonomic keypad for a portable device, and more particularly to a keypad having keys that are configurable by an end user for accommodation of specific character symbols and / or user predefined functions. BACKGROUND OF THE INVENTION [0003] Increasing advances in computer technology (e.g., microprocessor speed, memory capacity, data transfer bandwidth, software functionality . . . ) have generally contributed to increased computer application in various industries. Today, portable hand held terminals users produce and manage large amounts of data or information, as compared to their respective work load in...

AI Technical Summary

Benefits of technology

The solution enables one-touch access to special characters and functions, reduces physical strain, and allows for rapid and accurate data manipulation without extensive training, enhancing user productivity and reducing the risk of musculoskeletal injuries.

Problems solved by technology

Otherwise, the ensuing incompatibility can cause the hand, finger and wrist movements of the user operator to be somewhat strained, slowed, and even sometimes misdirected, resulting in not only unwanted and undesired physical stress on the operator, but also in undesired fatigue with resulting entry errors.

The results of such repetitive stress and errors while manipulating the keypad on a portable terminal can cause unwanted loss in time for correcting the errors, as well as a loss in productivity through stress related injuries suffered by the keyboard operator.

Such injuries may be severe enough to render the individual unemployable.

For example, repetitive stroking of an incompatible keypad can typically stress the wrists, elbows and shoulders of an operator.

As stated earlier, when continued over long periods of time, this can lead to repetitive stress injuries, such as carpal tunnel syndrome, which is a painful and oftentimes a crippling ailment affecting the tendons and nerves in the person's wrist area.

This can further hinder rapid and accurate data manipulation on a keypad interface.
