ABSTRACT:
FIELD OF THE INVENTION
The invention relates to telephony systems, facsimile systems, and computer imaging systems. In particular the invention relates to pen computing devices, and imaging of written documents.
BACKGROUND OF THE INVENTION
Today, the proliferation of wireless communication devices has provided the marketplace with powerful tools for communicating in real time. For example, the GSM wireless phone is quickly becoming a world standard for telecommunications. In fact, in many areas of the world, the GSM phone is replacing land-line systems as the standard platform for voice communications.
However, although such systems are well suited for providing customers with mobile systems for voice communications, as of today, such systems are poorly suited for delivering data over a wireless network. The systems that currently do exist for allowing the transmission of data over a network from a mobile system typically involve coupling the GSM, or other type of mobile phone, into an assembly of devices that can include a laptop computer, a cellular modem, and a GSM phone. With these elements coupled together a user can generate documents, faxes, e-mail messages, and other such media communications on the laptop computer system and then employ the wireless channel provided by the cellular modem and GSM phone to deliver the data across the wireless network. Although such systems can work well in certain applications, they are generally quite bulky, expensive, and involve too much overhead to be practical for transmissions of brief and quick data communications.
Accordingly, there is a need in the art for a communication system that is well suited for allowing a mobile customer to transmit voice and data traffic over a wireless network.
SUMMARY OF THE INVENTION
The systems and methods of the invention enable the integration of a pen computer input device into a mobile phone.
The systems and methods described herein provide communication systems that allow for the transmission of voice and data over a wireless network. To that end, the systems described herein include a mobile wireless communication system, such as a GSM telephone, and a pen input device capable of collecting information about an image written on a writing surface and capable of transmitting that information into the wireless communication device. In one embodiment, the systems described herein include a GSM phone that has included therein a receiver unit capable of communicating with a pen input device. The pen input device can be a stylus that includes a plurality of sensor mechanisms which can measure forces being applied to a nib of the stylus. The pen input device can further include a transmitter that is capable of transmitting to the GSM the signals collected by the pen as the pen moves across a writing surface. Optionally, the transmitter can be a secure transmitter having a processor for encrypting and decrypting information transmitted over a radio cellular network. In one embodiment, the GSM phone includes a processor that can operate the receiver to collect the data signals transmitted by the pen input device. The processor can further format the collected data information according to a preselected data transmission format and transmit the data across a wireless network to a desired location.
In one particular practice, the systems described herein cooperate with a server at a remote location that can receive and process the data signals transmitted by the wireless communication device. In one such embodiment, the server can be equipped to compare data signals transmitted from the wireless device against templates of data signals stored at the server site, or stored at a location accessible by the server. The server can compare the data signals transmitted from the wireless communication device against the template information and determine a measure of similarity between the template and the transmitted data signals. Accordingly, in one practice, the systems described therein provide a system that allows for verifying the identity of a user at a remote location by having the user sign a document at the remote location with the pen input device.
The pen input device can capture information representative of the dynamic characteristics of the user's signature as well as information representative of the image of the user's signature. This information can be transferred from the pen to the wireless communication device, formatted for delivery over the wireless network, and transmitted to the remote server. At the remote server, the data can be analyzed, such as by dynamic time warping, or other known methods, and compared to information stored within the database, allowing a verification analysis to be performed.
In response to a successful verification of the user's identity, the system can provide a verification signal to a selected location. The verification signal can be employed for allowing the user to verify their identity for any suitable application, such as for authorizing a financial transaction such as making a purchase with a credit card, making a transfer of funds from one bank to another, becoming legally bound to a contractual obligation, or for any other suitable application.
In other applications, the data signals transmitted to the remote server can be processed to generate an image of what the user wrote on to the writing surface. The image can be delivered as part of an e-mail message, or as part of a white board application communication, or any other suitable application. Optionally, the image data can be analyzed by a character recognition process to generate a text version of the written information.
