I selected 3 multifunctional products and 6 people to achieve the test.
They were asked to do some simple tasks by using these products which they never use before.
From this product-use test, I try to find the reasons of their behavior. Here are some point as follow:
- As less button as possible: in the Sony radio clock and HP priner, I found that these two products contain too much buttons which will confused the user and he might make a mistake.
- Good mood will be better: at the first test, when some users cannot operate the product, they came up with negative emotion. One of them started shaking the product, the other one said " this product designed badly". Keeping a clear mind is difficult when they operate this product.
