Water Vending Machine UX/UI / about the project
Water Vending Machine is essentially a device that works without salesman. It was necessary to create easy and enjoyable communication between user and machine. User should be able to choose water type and required volume. There are three water types available: still, cold and sparkling. Each water type can be poured in three volumes: 0,5 liters, 1.0 liter and 1.5 liters.
When desired water is chosen, user should be able to pay for it. There are two ways to pay: via Pay Pass or via special bottle with QR-code. To learn more about Water Vending Machine visit project page.
Specification of interface elements
Water Vending Machine interface comprises four components:
1. Touch screen where user chooses desired water, its volume, payment type and controls refilling process.
2. Cashless payment terminal to pay via Pay Pass.
3. Terminal to pay via BWT bottle.
4. Bottle refill point.
UX scheme
Communication process between user and machine is shown below. User's actions are shown with white solid lines. User's inactivity timeouts or machine and payment errors are shown with red dotted lines. Blue dotted lines show the end of bottle refilling.
UI prototype
To feel user interaction with machine control panel, try interactive prototype below. Buttons interactions, screen transitions, pop-ups, graphic communication between devices are shown in prototype.
Try to refill a bottle with water to understand will it be easy and comfortable to you)
