The field of interaction design can be describe as a pragmatic approach to creating a controlled interface design for said designs users. The concept of aesthetic appeal is not abandoned in interaction design, in fact certain aesthetics can enhance the like-ability of a design causing users to overlook other flaws, rather interface design integrates aesthetic design with functionality design. The function being how certain processes are able to be carried out by the user. Interaction design studies users behaviors and creates a design based on satisfying their needs. At the crux of interaction design, the purpose is for the design to facilitate the experience for the user in ways such as ease of use and task simplification.
Key principles of interaction design are as followed:
- A property in which the physical characteristics of an object or environment influence its function. (Lidwell & Williams, 22)
- The usability of a system is improved when similar parts are expressed in similar ways. (Lidwell & Williams, 56)
- A method of limiting the actions that can be performed on a system. (Lidwell & Williams, 60)
- A relationship between variables in a system where the consequences of an event feed back into the system as input, modifying the event in the future. (Lidwell & Williams, 92)
- A relationship between controls and their movements or effects. Good mapping between controls and their effects results in greater ease of use. (Lidwell & Williams, 152)
- The usability of a system is improved when its status and methods of use are clearly visible. (Lidwell & Williams, 250)
Donald Normans principles of design are highly valuable to the design of communication that have practical purposes in organization and business communication. Below are examples of how Norman’s principles apply:
Any company with a product is surly subject to most if not all of Norman’s principles. For example affordance, the product is likely being used to satisfy a need or want of the consumer, is it successful? If the answer is yes that this communicates to the consumer that the company understands their needs and is seeking to fulfill them. Thus, establishing a good relationship with their consumers.
Most modern companies have a website affiliated with their business. Following Norman’s principles, mapping and visibility for example, could mean the difference of a successful site or failure. Essentially, learning what the consumer is utilizing your website for and then creating a site with a strong visibility and mapping to allow the user to get the most of you site whether it is services the company proves or simply general information.
I find Norman’s principles to be extremely valuable! What do you think of his concepts? Comment below!
