Nowadays, the mobile devices are used for accomplishing a wide range of tasks and activities. Nonetheless, interacting with them represents a considerable challenge for the visually impaired people, especially in what concerns the low level of accessibility and usability. At the same time, the visually impaired people cannot use the most common applications for mobile phones and are deprived of access to a wide range of essential information concerning the environment (objects, obstacles, and the presence of other people around, the ability of freely navigating). This paper is a review that aims to present and evaluate some of the most relevant mobile applications designed for the visually impaired users. These applications become accessible to the blind people by using sound, touchscreen and vibration in order to offer the necessary information for HCI. This research is taking into account the main characteristics, limitations, comments and improvement ideas.
