Integrated keypad system

Abstract

A data entry system includes a predefined number of keys for at least inputting arbitrary characters through the keys. The data entry system uses a number of symbols having at least the letters of the alphabet of at least one language and where the symbols are assigned to the keys such that at least two of the letters are assigned to at least one of the keys. A symbol assigned to a key is inputted by providing a predefined type of interaction such as one type of pressing action on the key and providing a speech information corresponding to the symbol. The speech information is detected and analyzed based on at least one of, a user's voice and a user's lips movements. The data entry system uses a database of words of a language such that in order to enter a word of the database a user provides a combined information corresponding to the word, where the combined information includes a first and second type of information. The first type of information includes entering precisely at least one of the letters of the word by providing a corresponding pressing action on a key corresponding to the at least one letter and speaking the at least one letter. The second type of information includes providing the key presses corresponding to at least some of the other characters of the word, and based on the combined information, the system predicts the word.

AI Technical Summary

Benefits of technology

[0030] One main advantage of this fingerprint detection device is its size. Rather than having a large numeric keypad for a phone, one can use a smaller fingerprint pad, using the methods discussed above. Similarly, computer keyboards can be replaced or modified, as well as PDA input devices, etc.

[0031] According to one embodiment, the fingerprint detection device is configured to distinguish between fingers based on their fingerprints. As such, this provides the user with a security advantage since the fingerpad would only operate based on a particular finger and is rendered useless in the hands of an unauthorized user.

[0032] According to yet another embodiment, the finger detection device detects biological differences between characteristics of fingers via a method other than fingerprint detection. These biological differences include, size, shape, position, temperature, etc. Thus, for example, the finger detection device can be configured to quickly distinguish one finger from another based on its size and shape. This process avoids the lengthy and complex task of scanning a full or partial fingerprint. It is understood that for finger print or finger biological recognition, different detection systems and devices such as sensitive touchpads of any kind, touch screens, thermal, optical or other recognition means may be used.

[0033] According to yet another embodiment of the invention, the detection device is configured to accept multiple forms of input to enhance accuracy and ease of use. For example, the detection device can be configured as both a finger detection and voice-recogni

Problems solved by technology

Yet, primarily because of human constraints, there are many obstacles to the growth of miniaturization in several areas.

For example, it may be desirable to have a portable computer that fits in one's wallet, but such a computer would not be useable without a large input device that enables human interaction with the computer.

Thus, as advanced as miniaturization technology may get, there are other human factors involved that prevent certain devices from realizing a truly miniature state.

Usage of the Internet or even entering a short message, engages a lot of complexity for the consumer.

This is a time consuming method and it frustrates the user.

Such approach engages a lot of problems such as out-of-vocabulary words or obliging the user to concentrate for selecting a desired word.

In addition, entering numbers or single characters are again time consuming procedures.

External miniaturized keyboards are also produced to overcome the problem but they oblige the user to carry two different instruments, interfering with the basic idea of small electronic products, which is their easy portability.

Unfortunately, considering the many complex aspects of an individual's voice, there is yet a recognition device that can accurately recognize voice patterns at a sufficient level where input devices can be com
