Hi, need to submit a 2250 words paper on the topic Computer User Interface and User Productivity. In particular, the user interface has to be ergonomically optimized in order to achieve the best results. Therefore, it is crucial to appreciate that the way a computer interface is designed will determine how efficient and how productive a person is going to be. The only problem according to Bullinger and Ziegler (1999) is that there is no one particular known way to increase the effectiveness of the computer interface. The debate on whether the interface should be optimized to give the user immediate and unrestricted access to information is one that has no imminent end.

Morgan, Waldron, King and Patrick (2007) argued that increasing the Information Access Cost can improve the performance as it helps the user to develop better and more intensive memory and cognitive function. In this regard, increasing Information Access Cost can be very is effective in increasing productivity for repetitive tasks. As the user is required to think and increase the intensity of this or her memory, he eventually increases his cognitive functions, thus being able to perform better in the future. Back, Cox and Brumby (2012) carried out a study to investigate how information access cost can affect the performance in terms of productivity and effectiveness. They found that increasing the information access cost can be useful in making sure that that the user does not overlook or ignore some important processes. In their experiment, they found that increasing the cost of accessing the information was important in making sure that the users were accurate in the way they carried safety-critical tasks.

Morgan, Waldron,&nbsp.King and Patrick (2009) also added to the debate and argue that increasing memory access can improve performance. In their research, they investigated how interrupting a person while he or she is carrying out a task can affect the way in which he will develop his cognitive functions.&nbsp.
