Question 2 (20 Marks) - Case Study: Nameless Paint Nameless Paint is a cool teaching and learning Japanese method in schools for developing creativity in kids. This method is made up of ten or more tubes with different colours in them, however the names of the colours in the tubes are not written on the tubes, but instead there are only spots of a particular colour or colours on each tube. The spots are also of different sizes. The designers aim is to change the way children think, he wants them to understand and learn how different shades of colours are created. For instance, a child picks a tube with a blue and pink spot of the same size on the tube but cannot tell which colour hides in the tube. She squeezes it and gets purple colour, then she learns that equal amount of Blue and Pink produces Purple Colour. Likewise, he picks a tube with large spot of blue and small spot of pink, he squeezes to get dark blue colour. He understands that if you mix a small amount 7 of the pick colour and a large amount of the blue colour you well get Dark Blue Colour. There are different colours hidden in each tube and the child must learn and understand how each of these colours are created, by mixing in different proportions. It's an easy and fun way to understand the colour theory. However, the concept must be learned by the child in order to understand how to apply the theory on the real tubes of colour. Assuming you are to develop an interface to teach the concepts to those who buy the nameless paints outside Japan. Following the design processes perform: i. Perform a PACT (People, Activities, Contexts, and Technologies) analysis, focusing only on people, in order to identify all the class of people who will use this system and make sure you design to meet the needs of all these people. Propose a prototype of the interface which would satisfy the learnability and simplicity principles of usability. Evaluate the Usability of your system, bearing in mind your users' needs and how the usability principles are implemented
