DotWalker is a travel assistant application primarily designed for blind and visually impaired users but it also enables eyes free control for all who like it. This application provides navigation by handling a set of discrete points. Each point can be approached using several modes of control (selected point, nearest point, point on route). Next, you can use a talking compass. Routes can be created on the move simply by shaking the device. Point of interest can be enhanced by audio record or linked with text file or web page. Special approach mode directs you to the desired point by announcing direction and distance. For each point can be added audio street view.
Application is easy to use by 2 or 3 finger swipes that can be configued to launch desired function.
This is free application. Many exciting features are available in DotWalker Pro, for example voice commands, navigation direction and map downloads and address announcement.
