Screen reading devices

In screen reading devices, the object or text template is placed under a camera. The image captured by the camera is processed by the device and displayed on a screen. The magnification, also referred to as the reproduction scale, can usually be adjusted on the device. The devices we offer achieve magnifications of up to 52 times. Kranz Vision exclusively sells screen reading devices with flat screens.

To improve the reading flow, many screen reading devices are equipped with cross tables. This feature allows for smooth and jerk-free movement of the text under the camera, making it easier to follow the text on the screen.

There are screen reading devices where the camera, monitor, cross table, and controls form a single unit, whereas there are devices where the monitor and camera are set up separately to ensure increased flexibility in placement on the desk or at the workplace.

Features

Electronic contrast enhancement is a great help for individuals with severe visual impairments, particularly for safely reading texts printed on colored paper. Contrast enhancement is a function of electronic reading aids that cannot be achieved by optical reading aids.

Another function to improve readability is inversion, also known as negative switching. This function swaps the color scheme of the text from dark text on a light background to light text on a dark background. This feature provides significant relief for many users while reading, as it helps prevent premature fatigue and also reduces glare from ambient light.

Advanced features for school, university, and profession

To enable employees to continue participating in professional life and to provide students with the opportunity for education, we offer advanced devices for these specific areas of application.

For use in schools, various reading devices are available that can be connected to a distance or panoramic camera. The usage can also occur separately. For example, a distance camera with a screen can be used first if the vision is still sufficient for reading at the desk. If the vision deteriorates, a reading device can then be added. Conversely, the reading device can also be operated independently and upgraded with a camera at a later time.​​​

In the office, reading devices with a PC interface can be used, enabling networked work. The screen can be shared, or the image from the reading device can be saved on the computer.

Diagnose

People with, for example, high-grade myopia due to degenerative changes in the retina, macular degeneration, optic atrophies, tapetoretinal degeneration, or other conditions that lead to a vision of 0.1 or less can be equipped with a screen reading device to compensate for the visual impairment.
