The Human-Computer Interface - Assignment Example There are various types of the human memory, and human have limited capability to process the information. This information is stored in the different types of memory.†¢Ã‚  Short term or working memory: The short term memory is the capacity and store situated in the frontal lobes. Its function is to manipulate and update the representation, dividing and switching towards the tasks, and selection for the appropriate information. The retention time of the information in the short term memory is from seconds to minutes.†¢Ã‚  Sensory Memory: It corresponds to the perception of an item, and some of the information goes to sensory store, which is actually called as the short term memory. The retention time in sensory memory is in milliseconds to seconds. †¢Ã‚   Long term memory: Cognitive theory is also known as the theory of long term working memory in HCI. This is a long term memory, and requires practice as a prerequisite. Long term theory supposes that information is enc oded in the long term memory, and pace of encoding enlarges with the practice. Information in the long term memory, is encoded in a very organized system. Contrary to Short term memory, the long term memory is not inferred by the secondary task. (Oulasvirta and Saariluomas, 2004).A design team does not know the people behavior about the use of a product. A designer pays a conscious attention for the designing of the internal consistency. Consistency is more required in graphics and layout, dialogue forms and selection techniques.... ensory Memory: It corresponds to the perception of an item, and some of the information goes to sensory store, which is actually called as the short term memory.

(Oulasvirta and Saariluomas, 2004). 3. Describe the potential outcomes of not using consistency in the human-computer interface. A design team does not know the people behavior about the use of a product. A designer pays a conscious attention for the designing of the internal consistency. Consistency is more required in graphics and layout, dialogue forms and selection techniques. Each domain of the interface has a set of consistent dimensions. Inconsistency in color, size, style and shapes may create issues for the user. For example, Move forward is consistent with Move backward, but reverse, Go backward is not consistent. Inconsistency in HCI also fosters the level of confusion and frustration for the user as a user may access or generalize the other menu. In case of the inconsistent information, a user takes more time to answer the question on the screen. 4. Summarize and explain the steps of the user-centric design process. An engineer only operates the system to construct the design. System is developed on the need of the users. The users’ involvement for the design process is
