On a recent trip, one of our hotels provided a Keurig single-cup coffeemaker with an assortment of K-cups. I took a few minutes to analyze the coffee maker user interface, while brewing my morning cuppa.
A visual “user guide” is printed on the side of the coffee maker, making it easy for national and international travelers to brew a beverage.
Plus, the coffee maker design guides users through the beverage making process. Push the button on top to get started. The Place Cup light glows, and the K-cup holder opens. Position the paper cup under the dispenser, and insert the K-cup. Close the holder lid, and the water reservoir lid opens up. Add water, and close the lid, and the Brew button glows. Press the Brew button, and the Heating light glows. Soon, the coffee dispenses into the cup.
This is an example of ideal user design. The traveler is treated to a great user experience and cup of coffee, with no need for written instructions.
