A fast-food restaurant uses a concept keyboard for taking orders at the counter.
(a) Describe how a concept keyboard, such as the one shown above, works. [2]
(b) State two advantages of using a concept keyboard instead of a standard keyboard in a fast-food restaurant. [2]
(c) State two disadvantages of using a concept keyboard. [1]
Answer Details
(a) How a concept keyboard works:
Each key on the concept keyboard is a large button with an image or label representing a specific item or action (such as "Burger", "Large", or "Complete Order"). [1] When the operator presses a button, it sends a signal to the computer system to add the corresponding item to the order or perform the associated action. [1]
Unlike a standard keyboard where each key represents a single character, each key on a concept keyboard triggers a predefined command specific to the application it was designed for.
(b) Two advantages of using a concept keyboard in a fast-food restaurant:
- Staff need very little training, as they only need to press clearly labelled picture buttons rather than learn a standard keyboard layout or memorise product codes. [1]
- Orders can be taken more quickly, since each button press directly selects a product, reducing the number of steps compared to typing item names or codes. [1]
(c) Two disadvantages of using a concept keyboard:
- The keyboard can only be used for the specific application it was designed for, unlike a standard keyboard which is general-purpose and can be used across many different tasks. [1]
