What are agreements?

The term of the subsidy was created in 1977 by psychologist James J. Gibson, one of the founders of Perceptual Psychologists. Gibson defined this concept as actions that are possible in the environment and in connection with the actor's capacity. The concept is illustrated through the stairs of the metaphor: the height of the step in relation to the size of the actor provides an increase. These event options exist whether the actor realizes or not. Gibson's definition is still used in perception and cognitive psychology in studying the actor's behavior in his environment, as well as in computer, web and industrial design. Donald Norman, a leader in design and usability, derived the term "perceived benefits" from Gibson's work. In the case of perceived benefits, the hobby benefits are those that the actor realizes that it exists when theinteraction with the item.

In HCI fields and interactions, it is important to consider the usability of interaction with a machine such as a computer. For this purpose, the designer selects elements intended to hand over actions or permits that will be enabled when the user isselects. In the web design there are examples of advantages that are used in many players of Internet players.

Physical restrictions and cultural conventions also help determine the usability of the item. In some situations, designers can refer to these considerations as advantages. In the HCI discipline, the computer width provides an example of physical restrictions, and designers often try to maintain screen design within the user screen size. An example of the impact of culture is the use of an envelope icon that allows the user to send -mail. The envelope would mean nothing for someone who had no experience in receiving paper mail via the postal system.

Along with the HCI and the design of interaction, the discipline of industrial design also relies on the understanding of perceived benefits. Their effective use can be crucial for the success of the product. When product designers think through behavior and relationship alreadyUsers for the product can choose a proposal that can improve product usability, market admission and safety.

Use of perceived benefits in commercial design can help people move more easily through their environment. In commercial buildings, the design of the door handle affects whether people are trying to open or push the door. Assigning the design of the handle to move the door can alleviate traffic flow.
