Printer – Scanner – Copier – Fax machine
Design Brief
To redesign the display and controls (interface) of the machine.
Present Design
The machine can perform four operations which is print, scan, xerox and fax. The initial research about the product, its environment, its user, user-machine interaction and the task analysis was done.
The last image shows the close up of the part of the machine that was redesigned.
Details of the machine
The images below show the technical details and the controls of the machine along with the problems identified with respect to the controls of the machine.
Concept explorations (sketches and software)
The concepts were thought of with respect to the rules to be followed in the ergonomics of any machine.
New Design (Value addition)
- Horizontal placement of buttons since horizontal movement of hand is easier and precise than vertical
- Four push buttons in a row since the push buttons in a row should not exceed four
- Required amount of spacing given with clear and prominent demarcations
- Easy legibility (Contrasting colour usage with respect to the background and the symbols on the buttons)
- Absolute error free numbering buttons, that is from down to up (central panel)
- Grouping of the LCD screen display and the 5 buttons as they are frequently used and as they are elements that need to be grouped
- Highlight of commonly used buttons with same colour code
- Naming of the machine in capitals according to the order of its function (starting from left to right)
Apart from these aspects,
- The buttons are all push buttons as they are easier to operate
- All the Start buttons (or any buttons pressed) will be backlit to let the user aware that the process is in progress and one need not press again
- The display screen will be a 7 segment display panel, which will be LED lit instead of dot matrix LCD which is very confusing.
