  • Patent number: 8284999
    Abstract: A reading machine has processing for detecting common text between a pair of individual images. The reading machine combines the text from the pair of images into a file or data structure if common text is detected, and determines if incomplete text phrases are present in the common text. If incomplete text phrases are present, the machine signals a user to move an image input device in a direction to capture more of the text.

  • Patent number: 8186581
    Abstract: A device for assisting a user to perform a transaction on a machine is described. The device receives data that specifies a transaction mode to use for processing an image and accesses a knowledge base to provide data to configure the device for the transaction mode, the data including data specific to the transaction mode. The device receives an image or images of a portion of a machine that the user will use to perform the transaction and processes the image or images to identify a pattern of controls on the machine and to detect the presence of a user-controlled pointing item over controls on the machine. The device announces to the user the name or function of the control closest to an end of the user-controlled pointing item.

  • Patent number: 8160880
    Abstract: Techniques for operating a reading machine are disclosed. The techniques include forming an N-dimensional features vector based on features of an image, the features corresponding to characteristics of at least one object depicted in the image, representing the features vector as a point in n-dimensional space, where n corresponds to N, the number of features in the features vector and comparing the point in n-dimensional space to a centroid that represents a cluster of points in the n-dimensional space corresponding to a class of objects to determine whether the point belongs in the class of objects corresponding to the centroid.

  • Patent number: 8154771
    Abstract: A user of an accessibility device is taught to properly use the device with a test image such that the accessibility device captures the entirety of or a large portion of a test image. In training the user, the device processes test image's information located within the device's field of view. Based on this processed information, the device indicates to the user if the device should be re-positioned such that a larger portion of the test image comes within the device's field of view.
