Describe direct manipulation and virtual environments

Assignment : Direct Manipulation

Early computer systems relied on command line interfaces to perform all actions. Today, the majority of systems use direct manipulation rather than a command line interface. The goal of designing a direct manipulation interface is to make use of the system intuitive to the end user. One industry that has been extremely successful designing intuitive direct manipulation inputs is the video game industry. Most game players are able to learn controls as they play a game and then apply the same controls to similar games. Rarely do they need to read a user manual.

Write a four to five (4-5) page paper in which you:

Describe the three (3) principles of direct manipulation and give examples as to how they are used in video game controls.

Analyze video game-type interfaces and discuss three (3) reasons why video game-type interfaces would not be effective for real-world applications.

Describe at least three (3) advantages of direct manipulation versus command line interfaces.

Evaluate direct manipulation and describe three (3) problems with it.

Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.

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 direct manipulation and virtual environments.

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

Write clearly and concisely about HCI topics using proper writing mechanics and technical style conventions.

Develop an app that provide support for decision making

Excel Project Description

Project overview

Develop a Microsoft Excel application that provides support for decision making. The application must be useful to someone, which means it needs to help someone analyze data and make appropriate decisions based on the data. Don’t waste your time creating something that has no purpose.

Demonstrate your ability to use Excel by integrating as many features of Excel as feasible. The project must be easy to understand and have a professional appearance. Use comments or provide instructions to help someone use the application.

Examples and ideas

· Make a tool for a landlord. Pretend you are a landlord or make it for a real one: Keep track of current renters, when people will be leaving, how many rooms you need to fill, repairs, cost for repairs, history of repairs, utility trends, who is on which payment schedule, or anything else you think is useful to a landlord.

· Create something that helps you or others choose what car to buy. You could include data about recalls, TSBs, complaints from other owners, 0-60 times, horsepower, costs such as insurance, depreciation, repairs, gas, etc. Show that one car is a better than another given certain criteria such as 4 door full-sized between x-y price range.

· Create a financial portfolio analyzer. Using real data from real securities, show comparative performance measures over time. In addition to analyzing the stock or bond performance, you might include a sheet for the business performance.

· Create a decision support system for a small business startup. This could include several what-if scenarios. Include an analysis of capital financing options.

· Create a decision support system for buying a house. Include variables such as commuting distance, property tax rates (use real data), mortgage payments at varying principal amounts and interest rates, proximity to shopping and other services, schools, etc.

Choose something that uses some sort of data. This way it will be easier to use charts and graphs and use formulas such as statistical analysis or nested-if statements. You can create your own data, make it up or get it from the Internet. Keep in mind that you should be able to show that your project accomplishes something even if it is for your own personal satisfaction.

At the end of each chapter is a set of “Practice Exercises.” Many of them suggest applications to solve real business problems that can be developed in Excel. Use these suggestions to help you brainstorm ideas for your own project.

Minimum requirements for Excel features

· IF-statements

· Multiple sheets

· Simple formulas (e.g., sum, avg, pmt, fv, stdev, median) – use cell reference where appropriate, including absolute references and references to other sheets

· At least two charts or graphs

· Attractive appearance – remove background grid, add a watermark, use color, or whatever is appropriate

Advanced functionality (at least 3 of the following – any combination)

· Complex formulas (e.g., nested-ifs-ands-ors, V- and H-lookups, IS functions)

· Data Table (NOT excel table)

· Sort function

· Pivot table

· Scenario tools

· Macros or VBA

External data requirement

· Bring in some data via an SQL query, Web query, or XML data import

Other requirements

· Title page/Introduction/Summary sheet that may include navigation instructions, tasks involved, project title, your names, sources of data, research involved, etc.

· Conclusion sheet or a sheet that explains what was accomplished. (Use this sheet to tell me where (sheet and cell location) you met the requirements.)

This project will demonstrate skill and proficiency in Excel. You should make it something you would be proud to show to a potential employer in a job interview.
