Observation 1

Technology: MetroCard Vending Machine.
Assumptions: A machine whose purpose it is to enable the user to purchase the necessary type of MetroCard.
Observations: Most people seem to know what to do and do it fast. Some people take more time reading through the different menus and deciding between the different options. It seems that every person that interacts with the vending machine is able to procure a MetroCard. It is hard to say if it is exactly the MetroCard they want/need. The fact that there are several steps to go through before getting the needed card makes the interaction slower then it could be but it is still fairly fast if one knows what they are doing.

The technology has good conceptual design, good visibility and good user feedback.
