Task Overview Your design proposal for a touchscreen interface for an Automatic Teller Machine (ATM) aimed at children has been accepted. You are now to produce a full conceptual design for this interface. Your Task: Create a full conceptual design for your ATM interface. This is to include: The order in which information is to presented to the user, The “route” (or Use Case) that a user will take to access each function of the ATM, Wireframes for each screen in your design, which are to include: All screen components clearly labelled, Colours to be used on each screen and each component, Help functions for users, User navigation. You should design your interface for a square touchscreen that is approximately 250mm (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. When making your final design, consider the unique needs of children in this age group. Some examples of issues you may want to consider are: The suitability of PINs for children, Physical differences between children and adults, and Issues that you may have discovered during your usability evaluation of your alternative designs. Your ATM interface must support the following functions: Access to the ATM through a PIN (or any other method you can devise that is suitable for children in this age group), Deposit, Fast Cash Withdrawal in the amounts: $5, $10, $20, Withdrawal up to $20, limit of once a day, Check the account balance
