The Vintage fan

Good aspects 

•    Easy to use;
•    Intuitive;

Bad aspect

• The indicators are clear, but are a little misplaced.The 2hours Timer label and Orientation label, should be in the top of the user interactions elements)

The modern fan

Good aspects:

• Modern and atrative design;
• New features

Bad aspects:

• Mapping very confusions;
• Icons meaning aren’t all clear;
• The on/off buttons aren’t Highlighted with visual relevance;
•  The labels of the hours, we do not know are related to which buttons;

Obviously we have to evolve more and we must be careful to keep things simple and especially to ensure that users do not have to memorize the instructions to use the equipment. Usable intuitively and with obvious affordances.
