BRIEF To create a terminal for a petrol station that allows customers to walk up and use at night in order to purchase a limited number of goods
REQUIREMENTS Terminal must have a touch screen and a smart card reader. Terminal must be installed at or near the current staff counter. Must be able to support direct/indirect transactions between customers and staff and between the staff and the terminal. Provide a safe solution for the staff. Appropriate payment methods. Complies with the Equality Act (2010).
CONSTRAINTS Access to stakeholders Reports on sale figures for small items. Information on petrol station layouts.
ERGO VENDER Ergonomic design. Simple kiosk interface. High product range. Multi selection and delivery. Easy to change products based on sale.

WORKSPACE LAYOUT
Customer insights Fast and easy to use. Clear labelling of products and pricing. Secure payment. Ability to undo actions without assistance. Give a receipt.
Staff insights Provides feedback when products are running low. Can be carried out by a single person. Oversize items must be collected from staff window.
Can be stocked at any time of day if embedded into shop.
SCENARIO
FEATURES Product screen Note slot Card reader Coin funnel Delivery bin
Smart card reader Change collection bin
THE SCREEN The screen is a resistive touch screen Angled at 30 degrees from vertical Placed at height 1200mm 23 inches for cost and also ideal comfortable viewing real estate.
CARD READER Angled at 67 degrees from the vertical into the panel Can be placed at a max height of 1200mm Placed low to prevent people standing behind wheelchair users viewing the pin numbers entered.
THE COIN FUNNEL
Developed for cognitive impaired users (e.g. drunks) to pay without requiring precision movement that a ordinary coin slot would require.
THE DELIVERY BIN The delivery bin is placed at the lowest acceptable height based on ergonomic guidelines. Clam-shaped for easy item retrieval. Large size to allow for simultaneous delivery of items.

CONCLUSION We consider the needs of the client and the users We observe the environment that the system is used We apply ergonomic knowledge to design ideas We test the design on real users We iterate as necessary
