Colors identification for blind people using cell phone

Abstract

Assistive Technology (AT) is an interdisciplinary research area that allows finding solutions to the individual with disability [1] by easing or improving the functions or the skills for accomplishing daily activities. A technology can be considered "assistive" if it is fit for the needs, skills and capabilities of the person, taking into account mainly the intended activity and the limitations of the context and environs where the person performs such activity. The current work intends to solve the problems of vision impaired persons to recognize colors. To this aim, a Java application for cell phones has been made which lets complement the mobiles' technology with that of image processing. The means to obtain the colors from a view are based on analysing the different color models join to a mechanism to reduce the collected data. This paper describes preliminary experiences, methodology and results considering the user perception.
