Benefits of technology
The patent describes vision assistive devices and user interfaces that help users see more clearly. These devices have a housing with one or more angled imaging units that capture images of objects on a surface. A control system then processes the images and outputs them to a screen on the device. The device can also be positioned perpendicular to a surface and capture images of objects placed on it. The technical effects of this invention include improved visual acuity and mobility for visually impaired users.
Problems solved by technology
Even people with the least degree of vision impairment may still face challenges in everyday life as typical everyday activities such as reading a newspaper become difficult if not impossible.
However, one problem with the current devices is that the current devices require complex set up before they can be used.
Moreover, operating current vision assistance devices can be problematic for a visually impaired person due to the heavy reliance of the current vision assistance devices on digital controls, such as a keypad, keyboard, a mouse, or a touch screen.

Embodiment Construction
[0021]The present disclosure provides vision assistive devices, systems and methods of use of vision assistive devices and systems.
[0022]In reference to FIG. 1, a vision assistive device 100 of the present disclosure includes a housing 42. The housing 42 may be made of separate parts integrated into a single unit. The housing 42 may include a base region 62 and a top region 64 connected by a front wall 66, back wall 68, and two side walls 70,72. The walls of the housing 42 may be continuous and, together with the base region 62 and the top region 64, define an inner volume for accommodating therein electrical components (not shown) for carrying out functionalities of the vision assistive device 100, as is described below.
[0023]In reference to FIG. 2, the housing 42 can be free standing. In some embodiments, the base region 62 of the housing 42 may be designed to enable the vision assistive device 100 to stand unsupported or unassisted on a surface 86 in operation. In this manner, th...

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.
