The visually impaired people face problems in doing the basic activities in their life: personal, social or professional. The visually impaired users have a number of software applications designed for computers and touch-screen devices. Such people can largely benefit from a mobile phone based application. Such an application can be based on the android platform and installed on a Smartphone. It can detect major colors, locate direction and mainly recognize objects. In this survey we consider different applications that are useful for the visually impaired and how they can be enhanced to meet the high performance required.
