There are many different kinds of vending machines in the world. Each offering a range of goods, requiring the user to part with some money. Figure 1.0 shows photos of two different vending machines, one that provides soft drinks and the other a range of snacks. Both use an instructional mode of interaction. However, the way they do so is quite different Describe the interactions required to obtain a soda from the first machine and a bar of chocolate from the second.
