Abstract
Vision assistive device and user interface are disclosed. In some embodiments, a vision assistive device includes a housing having a base for positioning the housing on a surface; one or more imaging units disposed along a top portion of the housing, each imaging unit being angled downward so a central axis of the imaging unit forms an acute angle with the surface so the imaging unit captures a target image from a target object; and a control system accommodated within the housing, the control system being connected to the one or more imaging units to process the target image captured by each imaging unit and to output the target image to a user.
