  • Publication number: 20250209894
    Abstract: The present disclosure describes a computer system and method for motion activated item identification. The computer system includes a memory and a processor communicatively coupled to the memory. The processor detects, based on a video of a user, a motion of the user while scanning a barcode of an item and in response to determining, based on the motion of the user, that the barcode scanned incorrectly, captures an image of the item. The processor also determines, based on the image of the item, an identity of the item and adds, based on the identity of the item, the item to a checkout transaction.

  • Publication number: 20090079704
    Abstract: A method and an apparatus for inputting operation instructions using a dual touch panel of a mobile communication device are provided. When the user's finger touches the second touch panel of the mobile communication device, the second touch panel detects whether there is a slide path. If no slide path is detected in a predetermined time, a no slide signal will be output. A stop signal as a confirmation key will be output after the touch on the second touch panel ends. If there is a slide path, then it is determined whether the slide path is a one-dimension or two-dimension slide path. If a one-dimension slide path is detected in a predetermined time, a slide direction signal will be output. A stop signal as a direction key will be output after the touch on the second touch panel ends. If a two-dimension slide path is detected, the slide path in each direction is recorded.
