week 3 post 2: direct manipulation and invisible interfaces

    The purpose of direct manipulation and invisible interfaces is to make sure the user is spending their time thinking about the task they are performing. Direct manipulation is the principle that users should like they are directly controlling the object of their task. It is also about designing interfaces that give themselves to interactions that feel more direct, and not only about designing interactions that feel like it is directly manipulating an interface. direct manipulation is dependent on the immediate feedback that would map directly to the interaction. Whether through the use of direct manipulation, the main goal is for the interface between the user and the task becomes invisible. 

    An invisible interface would mean the user does not have to spend time thinking about the interface that they are using. They instead feel as if they are interacting directly with the task. One mistake to avoid when creating interfaces is assuming because an interface as become invisible the design is great, because interfaces become invisible because users learn to use them, not just a great design. If users become more comfortable through experience and practice; the interface will begin to feel invisibly integrated in their task. the main goal in invisibility of design is to create interfaces that are invisible from the moment the user starts using them. To a large extent, that is the definition of usable design, designing interfaces that disappear between the user and their task.
