Design factors related to emotion have a considerable impact on user behavior. In some cases, the feelings people get from a product determine their image of the brand for years to come.

Anxieties about Surroundings

It is important for the user to be able to operate the product without feeling rushed or overwhelmed. It is also important for the product to be considerate of the environment as well as surrounding people.


All users get frustrated when they don't get the results they were expecting after spending a lot of time operating the product. To reduce user frustration, product designs must account for the clarity of the control panel, the manual, and other instructions, reducing the number of operation steps, and the customer support system.
