    Abstract

    This Master’s thesis addresses the development of an Android-based application to provide the color-blind and visually impaired students a multisensory perception of color change observed in a titration. The application records and converts the color information into beep sounds and vibration pulses, which are generated by the smartphone. It uses a range threshold of hue and saturation coordinates of the HSV (Hue, Saturation, Value) color space for detecting a color change specific to an indicator for e.g. shades of pink for phenolphthalein based titration and informs the users before and on attaining the end point. This approach can enable color-blind and visually impaired students to actively perform a fairly routine laboratory activity of titration.
