The interactive object I decided to review was the Willy Wonka Vending Machine. This machine is located inside the food court and Mount Berry Square Mall. Many people use this machine each day to buy the candy that they desire. The machine offers a selection between eight different types of candy. The majority of people who use it are either parents or small children. You can also choose to pay with cash or credit card, whichever is more convenient.
When secretly observing people using the machine, I found that most people would go get change so that they could pay with cash. I think this is generally because that most vending machines don't accept credit cards. Maybe there should be a large block of text on the machine that says credit cards accepted. The main difficulties of this machine is determining which candy to buy. It seemed as though most people could use this machine fairly easy since the instructions are very simple. The instructions were written for small children since they would be the most likely to use it.
The instructions are shown on a large touchscreen. The machine first prompts the user to choose to pay with cash or credit card. An amount is then displayed on the screen and the user either swipes their card or inserts enough money to purchase the candy. The user then selects the desired candy, and the machine determines the correct candy to dispense, and puts it in a plastic cup.
This machine generally good design since it does its job well. It is not difficult to use and its a lot of fun!
