Up for Discussion1.Making exciting, entertaining, professional-looking GUI applications becomes easier once you learn to include graphics images. You can copy these images from many locations on the Web. Should there be any restrictions on their use? Does it make a difference if you are writing programs for your own enjoyment as opposed to putting them on the Web where others can see them? Is using photographs different from using drawings? Does it matter if the photographs contain recognizable people? Would you impose any restrictions on images posted to your organization’s Web site?Answer:Student answers will vary. Many students feel that everything on the web should be free, especially if no profit is made from an item’s use. Others will want to respect artistic images, and to protect artists’ material. Images of recognizable individuals might lead to lawsuits about defamation of character; some will argue that if a photograph is of a celebrity or politician, that those individuals have implied consent to use their images because on their chosen professions. Some students will want to impose standards of decency on images posed at their organization’s website, but others will uphold first amendment freedom of speech principles and want no content to be off limits.2.Have you ever encountered any confusing icons—for example, one so abstract that you could not easily determine its purpose? If so, describe your experience. If not, find a confusing icon on the Web and describe how you would react if you found it in an application.Answer:Student answers will vary. Sometimes public washrooms are marked with icons that represent male, female, or family, and if the icons are not standard, it can be confusing deciding which door to use. Public places like parks and beaches sometimes have confusing signs such as a martini glass with a line through it. Does it indicate no glass or no alcohol? To someone unused to computer applications, the usual sign for “Reload this page” (an arrow making a clockwise circle) can be confusing. In many applications, a floppy disk often means “Save” which can be confusing to younger users who have never seen a floppy disk. A small reel of tape often represents voice mail, but tape has not been used to store audio messages for a long time.3.Playing computer games has been shown to increase the level of dopamine in the human brain. High levels of this substance are associated with addiction to drugs. Suppose that you work for a computer game company that decides to research how itsproducts can produce more dopamine in the brains of players. Would you support the company’s decision?
