Physical design of a remote device for the visually impaired¶
Introduction¶
A remote device for the visually impaired is a technological solution that uses various technologies to help the visually impaired perform everyday activities more independently and easily. These devices can be wearable or handheld. They can significantly improve the quality of life of the visually impaired by providing better access to information and resources. Remote devices can help them stay connected to their surroundings and fully participate in social and work activities, enabling them to live fuller lives. In the research below you will see our exploration of the design and function of such a device. Also, the most suitable wearable device option.
Already built devices¶
Audio devices¶
This device provides an output technologies such as phones, computers.
Braille displays¶
A braille display is a device that allows visually impaired individuals to read digital text using braille characters. It consists of a row of braille cells that can be raised and lowered electronically to display braille characters in real time. Braille displays can range in size from a few braille cells to multiple lines of braille, and may include additional features like cursor routing keys, thumb keys, and function keys.
Smart glasses¶
Wearable devices are smart glasses that use sensors, cameras and provide audio feedback to provide navigation support or assistance to people with visual impairments.
Screen readers¶
Screen readers are used to read the text on the screen, allowing visually impaired people to interact more easily with their smartphones. In most cases, these are built-in smartphone software that can be turned on by the user.
Explanation of Braille¶
Created by Louis Braille in 1824. Braille is a special typeface designed for blind people. It is based on the principle of plastic dots stamped into the material, which the user can perceive by touch. Every braille character is a grid of six dots arranged in a 2×3 rectangle. These dots can either be raised or not, providing a tactile representation of letters, numbers, and other symbols.
