Question:

Your assignment is to design a touchscreen interface for an Automatic Teller Machine (ATM). Unlike most previous ATMS, this new unit has an Android-style touchscreen (with multi-touch) and no physical buttons. Sketch three alternative interface designs for the ATM and indicate which alternative you prefer.

What to Do:

The goal of this assignment is to exercise your user interface design abilities. Creativity in balancing usability with the constraints of the interface will be essential to successfully completing this assignment. You should design your interface for a square touchscreen that is 10" in width and height. The resolution of the screen is not defined, but you can assume that the screen will have around 72 dpi. Remember that you are sketching your interface designs. We do not want to see designs that are accurate to the pixel-level.

When making your designs, consider the broad range of potential users for the ATM, including the elderly. Also consider the implications of replacing the physical buttons that are commonly found on ATMS with just a touchscreen, How will people know that the screen is touch-sensitive? How can you address problems that are common with touch screens, such as the mismatch between where the user actually touched and where they think they touched? Your ATM interface must support the following functions:

• Entering a PIN to access the ATM

• Fast Cash Withdrawal in these amounts: 20, 40, 60, 80, 10) * Withdrawal in any amount

• Deposit

• Check Account Balance For withdrawals, deposits, and balance checking assume that the user may want to inspect either their checking or saving account. All of these functions must be included in the user interface, but they do not need to be included on one screen. Make sure it is clear in your sketches how the user navigates between the various screens.
