The aim of this project was to develop a portable device that could make the life of a person with colour-blindness easier when it comes to deciphering colour. The design properties of the housing in which the components are held are portable, ergonomic, compact and user friendly. The project stems from my interest in developing ideas to help people with different conditions. Helping people who have colour-blindness is a small but necessary step in improving people's visual capabilities.
Various stages were undertaken to develop a colour detector or a device that helps people distinguish colours. The device contains a few different aspects. A colour sensor, an LCD screen and an Arduino. The main part is the colour sensor. This sensor is central to the system, as it collects data to be processed. When a button is pressed, the sensor deciphers the colour which is placed in front of the sensors lens. The data is collected by the Arduino, which processes the data collected to checking the recovered data against a standard table and sends the result to an LCD screen displayed to the user. The housing for the project was designed using adobe illustrator. The design involves taking the RGB sensor's focal length into effect which is 30cm. The RGB sensor can detect any colour placed within 30cm of the lens, therefore the design of the housing needed to take that into consideration. Research indicated that the components needed to be fitted correctly, so the sensor could pick up the correct colour at a set distance.
The project was iterative, when it came to building circuits and coding code for the Arduino suite. From the first prototype onwards there was a process of writing and re-writing the code, observing the effect of running the code, and learning how the system behaved and then reaching a new understanding of how the code worked. The system uses felt material at the input, and experimentation was needed to improve the accuracy as the material was transparent on some colours but was solid on others.
