Initial idea of the project was to understand the emotions based on light and colour using some wearable device, which will help the designer and the lay man to set the mood and to take the informed decisions. But due to the time constrain the project this had to be converted to a research project where the said things are understood and proved using experiments. The whole process of the experiment introduced me to the research process starting from the literature review, designing questionnaire & experiment, defining protocol, Analysing the data, both qualitative and quantitative, descriptive statistics, box plot, finding co-relation and so on. From the understanding from the literature, there had been lot of work done around the colour and emotion, but less is been explored on the different saturation level of coloured lights. Due to time constrain the research if restrained to only two colours and analysis based on descriptive statistics and box plot.
