Fuel dispenser
display and control
guide: Mr. Prasad Chowdary
Brief: To design a display and control system for a fuel dispenser, that aids not only to the operater but also to the customer thus making it efortless to use & efficient in clarity of information and feedback
Problems identified:
Problems identified:
1. Information is scattered
2. Contrasting colors do enhance clarity, but repetitive use is disturbing for the user.
3. Size of display: It is visible only to the operator , while the customerfrom that distance cannot see the quantity he gets forthe amount paid. (customer satisfaction: Visible product feedback)
4. The orange back light used is not very visible at night.
5. Petrol consumption meter is inconspicuous.
6.There is no distinction between price, volume and rate displays.
7. The instructions printed on the display board has worn off.
8. There is no clarity of information in the pictographs.
9. The sequence of operation largely dependson the position of controls. Here instructions and keypad are very far apart because of which it becomes difficult forthe user to refer and operate the machine.
10. The layout of information and display is disorganised.
Example of an existing fuel dispenser display
Instructions panel
Simple pictographs supported by text for effective communication
It will be placed in the center of the two keypad to facilitate ease of reference
Final concept
Segregated display and control panel
Display panel : Fuel rate, price and volume along with the card swipe slot.
Control panel: Keypad, function keys, tag reader, instructions panel
The keypad is separated from the function keys
The font size, type, spacing and elevation is given keeping in mind all ergonomic factors.
Tag band (to be worn in the wrist)
1. The purpose of the tag is to make sure that only the assigned operatorcan access the dispenser at any point of time.
2. Instead of having to hold a key chain on one hand and operate with the other, in this design I have introduced a band/ strap that has sensors for the tag reader.
3. This way, the user can wear it around his wrist and when he proceeds to type on the keypad it detects the tag and allows easy usage.
4. When there is an error the red light will flicker and not get unlocked.
