Dot Navi was designed to play the role of a navigation system: when visually impaired people look for an item they often use and want to know the location of an obstacle or its direction. It is easy to go somewhere by oneself and to look for an item one needs, but for some people it is the most difficult and challenging task. Helping those without sight to do these “simple” things is the purpose of this invention. Dot Navi provides the exact direction of the set destination on a twelve-hour clock face regardless of where a user is at the moment or where he / she is going, and thus offers an equal and familiar user experience to everyone.
