Computer applications that run on desktop and laptop computers have, for a long time, been designed to be driven by dragging and clicking a mouse. With the introduction of tablet personal computers, the trend has shifted toward using touch-based screens. We now have access to touch-based TVs, touch-based monitors, and touch-based laptops. Touch and multi-touch devices provide end users with the ability to interact physically with an application much more naturally. Imagine that you have been assigned the task of redesigning your company’s applications to run on all devices. Examine a multi-touch computer monitor and a mouse-driven computer monitor and think about how the end user interacts with an application running on each of these types of monitors. Write a four to five (4-5) page paper in which you:

Compare and contrast the metaphors used in the design of applications that run on each type of monitor. Use Microsoft Visio, Microsoft PowerPoint, or any other modeling tool to create.

Differentiate between the interaction types and styles that apply to these monitors and applications running on them.

Describe the conceptual model employed in the design of these types. Describe the analogies and concepts these monitors expose to users, including the task-domain objects users manipulate on the screen.

Use at least three (3) quality resources in this assignment.
Note: Wikipedia and similar Websites do not qualify as quality resources. You may use the resources above or others of your choosing.

Your assignment must follow these formatting requirements:

Be typed, double-spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.

Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

The specific course learning outcomes associated with this assignment are:

Describe the relationship between the cognitive principles and their application to interfaces and products.

Explain the conceptual terms for analyzing human interaction with affordance, conceptual models, and feedback.

Explain the importance of user abilities and characteristics in the usability of products.

Use technology and information resources to research issues in human-computer interaction.

Write clearly and concisely about human-computer interaction topics using proper writing mechanics and technical style conventions.

HUMAN COMPUTER INTERACTION

1. The WIMP or Window, Icon, Menu and Pointer based Graphical User Interface is the most 
dominant form of user interface in the world today. It was a radical shift from console or 
command line based interface, which predominated human computer interactions. However 
when Xerox came up with this radical idea of WIMP which then later got incorporated into 
Apple Macintosh and subsequently Microsoft Windows there was a paradigm shift in the way we 
accessed computers. Suddenly it became easy and the learning curve shrinks to a point that it 
was easy for even a novice to understand on how to operate computers. This form of HCI 
remained dominant until multi-touch based interfaces started coming up wherein users could 
interact with their devices using their fingers touching the screen directly. This was a far more 
superior way to access computers as it was more intuitive, simple and easier to learn. The WIMP 
based interfaces made use of design metaphors extensively in order to make their application 
intuitive, appealing, and relevant and a sense of context for their end users. So for example, a 
Desktop represented an actual work desktop, which included Folders, Files, Calculators, Text 
Processor and so on. However, with the Multi-touch based input, the same dynamics no longer 
apply. It forced developers and designers to think out of the box and come up with interactions, 
which leveraged the advanced multi-touch, based inputs. While the functionality remained same, 
their presentation and the way they could be accessed differed. So for e.g., a folder full of files 
would require one to scroll down using their mouse pointer by clicking and dragging the scroll 
bar, in the case of a multi-touch based monitor, one can simply tap and hold the screen and then 
flick it upwards to scroll down to the required file even faster and more accurately than the point 
and click based interaction of the WIMP interface.  
I will be comparing two examples of both of the interactions. The first one is the comparison 
between the point and click and the multi-touch based inputs based on the popular scroll bars.
As described in the diagram, the point and click interface requires a dedicated scroll button if the 
items displayed in the window, which is longer than the vertical, or horizontal screen area. This 
scrollbar is just like a switch or a knob, which implies that it is used for dragging the contents up 
and down or sideways. Whereas on the multi-touch interface, there is a very slim scrollbar 
visible only when the page itself is dragged upside and down or sideways. So in this scrollbar 
itself is not required to be dragged rather the user can put their finger anywhere on the window 
and drag it upside and down or sideways.  
In the second example, I have decided to compare the popular desktop or the home screen on a 
WIMP device with that of the home screen of multi-touch based devices.
In the first case, the desktop essentially represents a physical desk workspace where Folders, 
Files, Calculators, Text Processor etc. are present.
