Human computer interaction Annotated Bibliography

Human computer interaction - Annotated Bibliography Example Selection scheme tests showed the amount of buttons and kind of pointing device to select text. Icon tests showed the optimal shapes for recognition. Graphics tests showed that the line drawings interface needed revision. The focus was on basic users of computers who relied on recognition largely. The system was to be kept as simple as possible so that learning did not pose much of a problem. The studies conducted were largely qualitative in design except for the selection schemes that were tabulated statistically in terms of errors during usage. Even the statistical portions of the study were not well documented enough to warrant sturdy critique. The study is largely irrelevant in terms of HCI today as the study represents basic and early developments in HCI. The paper can however be considered to be watershed as it addresses major questions for development of user interfaces. The results of the paper are also significant as modern trends in user interface creation are similar to th e findings of the paper. Moreover the paper displays some bias as it only investigates a limited number of human cognition areas. The total study spanned six years and multiple tests which indicates that more issues could have been addressed. The paper is highly relevant to HCI as it represents the trends in the early development of HCI in general and the early development of graphical user interfaces in particular. The paper represents a shift from qualitative investigation methods to quantities methods. In itself this paper is symbolic of the transformation from qualitative investigation to quantitative investigation in the field of HCI. The paper is also reflective of how small segregated development has helped to make HCI and user interface design what they are today. Bush The author of this paper is a respected scientist in the scientific community of the Allies. The paper is set in the immediate aftermath of the Second World War and the author concentrates on the large amounts of learning and research produced during the war effort and the inaccessibility posed by the large volumes of information available. Towards the middle the author begins to envision the kind of devices required to access the large banks of information with the greatest convenience. The idea is further developed to envision a device resembling a modern computer in principle but differing largely in terms of design and operability. The author is confined to the use of hardware based techniques to achieve large advances in user interfaces. The chief methodology utilised by the author is speculation based on advances in user interfaces and HCI as far as the Second World War. The excessive utilisation of speculation as the chief method discounts the credibility of the paper to a large degree. The author’s findings are nothing more than mere ideas with little practical ground to bank on. The paper cannot be declared to be a watershed as there is little evidence that the advances i magined by the author were put to practical use immediately. Instead the evolution of HCI and user interfaces went through multiple other stages before it got to its current state. The paper can be related in its speculation to modern technology especially for indexing although the author’s methods for indexing are irrelevant today. Moreover the compression of data speculated by the author is highly relevant to ground realities today although again the author fails to provide any real solutions for it. The study is biased towards qualitative speculation rather than taking facts and building on them. There is not quantitative data or research anywhere in the paper at all. The paper can be seen as very early attempts at envisioning modern user interfaces
