com). Although basic trackball mice are still commercially available, they have been largely overshadowed by newer versions of the computer mouse based on optical and laser technologies. All computer mice allow the user to control the position of a cursor on the screen (or alternatively, a player position in a game) as the trackball, optical or laser sensors detect user movements and translate those into digital input. The mouse devices installed on the latest versions of laptop computers work differently from trackball and optical mice that are external to the computer but the underlying input principles are the same for laptop track pads and click buttons as they are for external mice. External mice may be wireless as well as wired, allowing users increased ergonomic flexibility. Like most computer-related inventions, the mouse has had a positive effect on social change. Making computers more accessible to a greater number of people, making the machines increasingly user-friendly, and increasing the locus of user control over software applications has meant that the mouse has helped democratize computing. Without devices like the mouse, average daily users would not be able to simply "point and click" and therefore would be less inclined to use...
Although touch screen computers and other non-mouse methods of input are emerging on the 21st century market, the mouse remains a primary, fundamental feature of the personal computer (Peterkin 2008).
Because of the standardization and flexibility of the mouse, software developers have considerable leeway in their engineering. Alternates to the mouse such as the light pen and tablet do not provide users with as robust and diverse usages as the mouse. Mice, moreover, are inexpensive. Although users can opt for high-end mice, most standard mice and even optical and cordless mice are affordable for the average consumer. Early mice, contained
In some areas it will be used for more populist applications such as, in schools to introduce students to the discipline and within an environment that will give opportunity for participation of non-academics in academic discussion. Conclusion Computer has in a great deal widened the world's knowledge. As the fastest technology that has ever evolved, it has given opportunity for the children and adults, for personal, academic and commercial use. It
In the second case, failing to maintain the forearms in a horizontal position can also trigger similar problems. This frequently occurs when users maintain their keyboards and mice on their desks instead of using a sliding keyboard and mouse tray. Prolonged use of keyboards and mice in an elevated position relative to the elbow causes wrist problems because of the continual downward bend required in the wrist. The solution to
Another reason why the shrinking of the microchip remains the most significant technological change to take place in American society is because of the cellular phone and handheld device revolution. Mobile phones are essentially handheld computers with microchips and firmware. They help keep Americans connected with their families, friends, and coworkers. The same technology used to make small devices more powerful can also be used to help the disabled and
Technology Evolution Many of the electric gadgets we use today like the cell phones and the home computers were invented in the 80s. Many multinational corporations came into existence in the 80s this spur the growth to a record 3.2% per year (Bellis, 2012). This was the highest nine-year rate in American history. This was occasioned by a number of factors some of which were economic, financial, legislative, and regulatory frameworks.
Online Video Business Model and its Impact on Communications What is Online Video? Online video is more commonly referred to as "streaming video" which is "video that plays over the Internet without downloading to the end user's computer. Think television and radio for your computer. Streaming is different from downloading in that playback starts immediately with just a mouse click for the viewer, and the large file is not saved to
