social and ethical issues
The widespread use of information technology has raised a number of ethical issues for people. The following are some of the issues that relate specifically to displaying data.
- The communications skills of those presenting displays need to be effective. Presentations are effective if the information displayed is well organised, attractive and easy to understand.
- Current trends in display are changing the way people interact with computers. Fifteen years ago screens were small and unable to handle different font sizes and graphics. Today larger monitors can display text, graphics, photographs and video. Display technology using large flat screens is becoming more common.
- Visually inspired people need appropriate displays. This issue is a concern on the Internet. Web page designers should consider how people with disabilities will be able to access their information. For example, it may be necessary to provide text alternatives to audio information for the hearing-impaired. All people with a disability are entitled to access technology. Special devices have been developed to help people with vision, hearing, mobility and dexterity impairments.
- Offensive material available on the Internet such as pornographic, racist and violent material is a major concern. Children with Internet access can potentially view inappropriate material, either deliberately or unintentionally. There is a significant amount of offensive material on the Internet and it is easy to find. Some people believe that offensive material should be banned, while others argue that banning any materials compromises our free society. Clearly, parents and schools need to prevent children from accessing offensive material. Censoring software such as Net Nanny can also be used to screen out inappropriate material. Chatting on the Internet is also an issue. Some people can behave in ways that is offensive and threatening, and may even have criminal intentions. In order to be safe, it is advisable never to disclose any identifying personal information to anyone over the Internet.
