Three types of design evaluation

The three types of design evaluation are the controlled settings involving users, the natural setting involving users in the real world and the final in any setting but not involving users.

The first one is when the designer sets an erected environment to watch the users how they interact with the product and their reactions and feelings. The second one is when the designer observes the user will using the product but in a natural setting/ environment. The final one it is the technique where the designer asks the opinion of an expert about a design and its capabilities.

An example of a natural setting evaluation technique is the application for the skiers (see Figure 1), where the designer goes to the snowy mountains to observe whether the user can use the application while wearing gloves. Therefore, for the designer to observe whether the use is capable of seeing the screen clearly since sometimes the radiation of the sun might be a reason of not seeing clear.
