摘要:
In various embodiments, the size, shape, and arrangement of keys on a virtual keyboard may be determined based on touchscreen contacts made by the user. Further, the actual contact patch made by the user may be analyzed to interpret which point of contact was intended, and other factors such as spelling and context may also be considered. These factors may be determined based on a calibration session and/or on continuing inputs during operation of the keyboard, and applied to future operational interpretations of the touchscreen contacts.

An image enhancer device for use with an associated mobile electronic device having a digital camera. The image enhancer device includes an image manipulator coupled to a first region of a housing and configured to modify an optical path of the digital camera; an aimer having an aiming element configured to direct at least one aiming light beam towards an object of interest; an illuminator having an illumination element configured to direct at least one illumination light beam from the housing towards the object of interest; and electronics allowing for communication between the image enhancer device and the associated mobile electronic device. The image enhancer device forms a scan angle relative to a field of view of the digital camera of the mobile electronic device and allows for bar code imaging and/or native image processing with the digital camera of the associated mobile electronic device.
摘要:
A system and method for providing visual feedback to facilitate multi-code (e.g., barcode) reading (i.e., scanning) is presented. The visual feedback will project a read status for each code scanned. The visual feedback for a particular code will be projected onto that code. For example, an "X" projected onto a code would indicated that this code was not read and needed to be scanned again. This visual feedback minimizes the number of codes that need to be rescanned in the case of a read error.

Various embodiments of the invention may be used to verify that a person being authorized by biometric techniques to use a device is a living person and not some form of recording intended to spoof the system. Some embodiments may try to cause a change in a measured biometric feature, and compare images taken before and after the change to verify the change occurred. In some embodiments, multiple stages of verification may be used, either to increase the difficulty of spoofing the security system, or to provide different levels of security for different levels of access to the device's functionality.

A checkout system includes a clerk-operated bi-optical workstation through which products having target data are passed to a bagging area, and a customer-operated accessory reader having an accessory window facing the bagging area and a data capture assembly for capturing additional target data of additional targets associated with transaction-related items, particularly over a restricted range of working distances that terminates short of the bagging area, and for preventing the accessory reader from capturing the target data of the products in the bagging area.
摘要:
A hand held device containing at least one camera can perform various functions. In some embodiments, digitized images taken with two or more camera lenses having different fixed focal lengths may be combined to emulate a high-resolution optical zoom, and may also permit the device to perform 3D applications. In other embodiments, a device containing a camera may perform as a bar code reader, and may wirelessly transmit and/or visually present a bar code to other devices. Movable optics may permit the same camera to focus on either distant objects or on a close-up bar code.
