A Smart Aid for Visually Challenged in Face Detection and Recognition

Visually challenged people generally need assistance to navigate through the existing dynamic world and constantly face many obstacles in the process. With an aim to not let the physical challenges hinder their growth and render them independence, to an extent, this paper proposes a simple and economical device for the visually challenged. This device consists of a hat (with a camera attached) and headphones. The device warns the wearer if any person is approaching, through a voice message, and announces whether the said person is familiar (with name) or unknown. This enables the wearer to assess his/her surroundings. The hat is affordable and convenient to use without any complications. This can also be used by people with partial vision as well.
