Abstract: A prosthetic processing apparatus (200) for use by a visually-impaired subject comprises at least one sensor (104) configured to capture and output physical information of a spatial field, an output interface (208) coupled to a sensory input device which is configured to apply a signal to a sensory pathway of the visually impaired subject, and a processor (202) operatively coupled to the sensor (104) and to the output interface (208). The processor (202) is configured to receive (402) the physical information of the spatial field from the sensor (104), and to process (404) the received information to identify one or more salient features of a predetermined category (such as edges, plane surfaces, human faces and/or bodies) within the spatial field.

Abstract: The present invention relates to a computer-implemented method, comprising: at a device with a touch screen display: displaying a first electronic document, comprising a plurality of locations, each location associated with one of a plurality of further electronic documents; detecting a touch event at or near one of the locations as represented on the touch screen display; translating a first portion of the first electronic document in a first direction; translating a second portion of the first electronic document in a second direction such that the first electronic document is displayed as splitting into the two portions at a split location; and revealing a second electronic document associated with the touched location within an expanding gap between the two portions caused by the translation of the first electronic document. A device and computer readable medium are also described.
