Human computer interaction (user interface ) - Coursework Example Reference: Chapman, Callum. "Common Elements Used in Interface Button Design."Â  Web Designer Dept. (2011): 4. Web. 20 Dec. 2011. . TYPOGRAPHY The fonts and typefaces are important elements of the user interface. It should be in proportionate with the design or else it will just look like a clutter. I learned that it should draw attention to the content taking in consideration its size, lines and shade. The overall appearance of the font is in conjunction with its readability which is highly essential for the end-user. Moreover, the amount of text in a given space should be kept to a minimum. The relationship of the font color and background is equally vital in achieving high contrast content which further adds to the readability degree of the content. Lastly, I also learned that appropriate spacing and the presence of empty fields are techniques to achieve visual relief, in this way; the viewer will not be distracted from the focal contents.

I also learned that combinations with positive polarity such as the use of dark text on a light background are notably effective. This is particularly important when dealing with visually-impaired users. Reference: Hall, R. and Hanna, P. (2004), The Impact of Web Page Text-Background Color Combinations on Readability, Retention, Aesthetics, and Behavioral Intention, Behaviour & Information Technology, forthcoming VIRTUAL KEYBOARD DESIGN Inputting is the concomitant interaction the user performs. It should be simple despite the complexities of the keyboard’s overall features. In the case of virtual keyboards, wherein industrial design is left out in place of a touch interface, the tactile response time should be fast enough to let the user focus on inputting end and not worrying whether the characters has already been displayed. It is fairly important that the on-screen keyboard should be able to interact with the fingers and not merely by using the stylus. It is a fact that th e best pointing tool is our finger; the keyboard’s design should be able to accommodate the multitasking capability of a human hand. The spacing of each character should be accurately be considered to avoid erroneous inputting. Reference: Xiaojun, Bi, Barton Smith, and Zhai Shumin. "Multilingual Touchscreen Keyboard Design and Optimization."DGP. (2010): 1-34. Web. 20 Dec. 2011. . I learned that in an on-screen keyboard, screen clarity and size are important elements. The spacing between characters avoids unintended inputs. In line with this, the user should be able to perceive that

Using an extended example critically discuss the view that a sector matrix gives a better strategic understanding of product markets than the concepts of product or commodity chains - Essay Example The automobile industry is the best industry to examine when it comes to commodity value chains and the sector matrix, because it often produces complex products that have complex distribution channels (Plunkett, 2009).

This paper through the use of Ford Company intends to show that a ‘sector matrix’ often gives better and strategic understanding of the product markets as compared to the concepts of product chains. It is important to note that the commodity chain has different value chain approaches. The value chain often describes that activities that usually take place in business and relates them to an analysis of the competitive strength of businesses (Bharati, 2012). The value chain analysis often identifies which activities should be undertaken by a big business and which one is best outsourced. The value chain is important as it gives a strategic understanding of the product markets (Carbaugh, 2013). The commodity chain is important as it also reveals a lot about the international configuration of production as well as the global economy. For this reason, it can be said to represent a distinguished field of study which helps in understanding the different products in the market (Nieman, 2006). Understanding significance of a commodity often represents a comprehensive approach as it includes an array of activities. For example, in the automotive industry, it often identifies the actors as well as the processes that often contribute to the inauguration of merchandise that is consumed by the market (Nieman, 2006). This includes raw resources, the assemblage of different parts and the distribution of the automobiles in the industry (Carbaugh, 2013). The automotive industry is very complex, for this reason there are several perspectives that are used to look at the industry and its products. The first
