Examples of systems and methods for a wearable system to automatically select or filter available user interface interactions or virtual objects are disclosed. The wearable system can select a group of virtual objects for user interaction based on contextual information associated with the user, the user's environment, physical or virtual objects in the user's environment, or the user's physiological or psychological state.

A method of processing a purchase transaction includes generating a transaction file containing a product code, which is transmitted from a user computing device when an image of a product code identifier is captured by the user computing device, a first user ID of the customer, and an indicator of whether or not the customer has opted in to receive electronic receipts. The method further includes generating an electronic receipt based on the transaction file, storing a conversion table containing the first and second user IDs of the customer, converting the first user ID contained in the transaction file to the second user ID based on the conversion table, when the indicator indicates that the customer has opted in, and storing the electronic receipt in association with the second user ID. The electronic receipt is transmitted in response to a request for electronic receipts associated with the second user ID.

Methods and systems include using three-dimensional imaging apparatuses to capture three-dimensional images and analyze resulting three-dimensional image data to enhance captured two-dimensional images for scanning related processes such as object identification, symbology detection, object recognition model training, and identifying improper scan attempts or other actions performed by an operator. Imaging systems such as bi-optic readers, handheld scanners, and machine vision systems are described using three-dimensional imaging apparatuses and described capturing three-dimensional images and using with captured two-dimensional images.

Disclosed are a method and terminal for scanning. The method for scanning of the terminal, provided by the embodiments of the present disclosure, includes: monitoring whether the terminal opens a bar code identification function or not; if monitoring that the bar code identification function of the terminal is opened, scanning a bar code by utilizing an edge touch area of the terminal; and executing a corresponding operation according to the scanned bar code. The technical solution provided by the embodiments of the present disclosure is used for solving the problems that long time consumption and low bar code scanning efficiency existed in the prior art, which is caused by the bar code being scanned using the camera, the camera needs to be focused first and then the bar code is acquired.

A checkout-system for retail is disclosed for secure and comfortable checkout of collected articles, whereby the customer scans the articles with a mobile article scanner by itself, and whereby the checkout-system includes a security system with an RFID scanner to scan RFID-transponder placed on the articles to identify whether all articles bought by the customer were scanned.

Systems and methods of monitoring progress of delivery of a patient-specific medication are disclosed. A patient/medication identification (ID) device is provided on a package containing the medication, the patient/medication ID device comprising medication/patient information indicative of the medication and the patient. At least one location ID device is provided at a location, the at least one location ID device comprising a unique location ID associated with the location. The medication/patient information and the patient/medication ID are read. Delivery progress information indicative of a last-known read location where at least one of the medication/patient ID information and the unique location identifier was read is generated. The delivery progress information is stored in a database. The delivery progress information is accessed from the database in response to the request. A delivery status of the medication is indicated to the user.

This disclosure relates to advanced signal processing technology including steganographic embedding and digital watermarking. One combination disclosed in the description includes an apparatus comprising: memory storing an image comprising a plurality of color channels; means for locating image areas including an encoded signal with each color channel of the plurality of color channels, said means for locating identifying a plurality of image areas; means for generating one or more detectability measures corresponding to the encoded signal for each of the plurality of image areas; means for determining whether the encoded signal can be decoded from the plurality of image areas to obtain a plural-bit message component carried therein; means for selecting, per color channel, only one (1) image area as a validation point based on one or more generated detectability measures for that color channel, and based on whether the one (1) image area includes a decodable plural-bit message component; and means for generating information associated with a spatial location of each of the validation points in the image. Of course, other technology, features and combinations are described as well.

An automatic object identification scanner is equipped with recognition units that provide detection results for objects and a controller that resolves potential conflicts in the results. One form of recognition unit detects product identifiers and flags in a digital payload that is encoded redundantly across packaging or labels applied to packaging. The controller gets detection results and evaluates them relative to a state data structure, which maintains state for identifiers obtained within a time interval, such as a timeout interval or waiting period after a detection result. Identifiers are reported to a POS system depending on logic that evaluates code priority and pending waiting periods.

There is described a metal workpiece generally having a surface and an identifier marked on said surface. The identifier has cells each having a corresponding cell size, including bright cells corresponding to a first binary value and dark cells corresponding to a second binary value different from the first binary value. The dark cells include a center portion being recessed relative to the surface thereby leaving a recess bounded by a peripheral wall in the corresponding dark cell, the recess having a depth of at least 100 microns and having an opening with a width ranging between 400 microns and 1750 microns and representing between 30 percent and 99 percent of the corresponding cell size such that the corresponding dark cell appears dark to an optical reader. The depth, the width and the cell size of the dark cells provide a shot blast resistance to the laser-marked identifier.
