Benefits of technology
Enables efficient and intuitive data collection by allowing operators to aim the image reader at any data type and actuate a trigger, automatically decoding barcodes and capturing signatures, reducing operational delays and training costs while maintaining ease of use.
Problems solved by technology
One disadvantage of this approach is that the manual selection process requires additional training for personnel.
Another disadvantage is that the manual selection process can be time consuming.
In the field of data collection, a premium is placed on efficient quick operation and even slight delays can be significant.
The dataform approach suffers from several drawbacks.
One drawback is that if the dataform, such as a linear barcode or two dimensional symbology, has been damaged due to handling or defected through printing, the dataform decode failure will render the signature capture inoperable.
Another drawback of the dataform approach is that space constraints can make it difficult to accommodate the space required for a dataform.
For example on some shipping labels and on some driver's licenses, little free space is available for additional graphic elements.
A further drawback of the dataform approach is that its operation is unintuitive.
The result of this unintuitive approach is that frequently the signature image will be clipped due to improper orientation of the image reader.

Embodiment Construction
[0026]The invention features a system and method for automatically discriminating between different types of data, such as a barcode and a signature, with an image reader. In brief overview of one embodiment, the automatic discrimination feature of the present image reader allows a human operator to aim a hand-held image reader at a target containing a dataform, a signature, or another element and actuate the trigger on the image reader. An autodiscrimination module in the image reader analyzes image data representative of the target and determines whether the target contains a dataform, a signature, or another type of data. If the target contains a dataform, the image reader decodes the dataform and outputs decoded dataform data, such as the alphanumeric sequence encoded by a barcode. If the target contains a signature, the image reader captures a representation of the signature. For other types of data, the image reader performs a correspondingly appropriate operation such as opti...

There is described a system and method for automatically discriminating between different types of data with an image reader. In brief overview of one embodiment, the automatic discrimination feature of the present image reader allows a human operator to aim a hand-held image reader at a target that can contain a dataform and / or a signature and actuate the image reader. An autodiscrimination module in the image reader in one embodiment analyzes image data representative of the target and determines a type of data represented in the image data.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 10 / 958,779 filed Oct. 5, 2004 entitled, System And Method To Automatically Discriminate Between A Signature And A Dataform (now U.S. Patent Publication No. US2006 / 0071081). The priority of the above application is claimed and the above application is incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to data collection in general and particularly to a system and method for automatically discriminating between different data types such as a signature and a bar code.BACKGROUND OF THE INVENTION[0003]Some currently available data collection devices, such as hand-held image readers, are capable of capturing signatures as well as reading barcodes. The reading and decoding of a barcode represents an operation distinct from that involved in capturing a signature. The reading and decoding of a bar code involves the imaging and then decoding of a ...
