The history of the computer mouse started in the 1960s when Dr. Douglas C. Engelbart and his acquaintances at the Stanford Research Institute (SRI) developed the innovative computerized pointing device, which is broadly recognized as being the first mouse. That computer mouse and Engelbart’s imaginative idea of human communication among people and the computer launched the industry that has placed hundreds of millions of pointing devices on desktops. By the same token; as soon as Microsoft Windows
The Basic Computer Hardware Central Processing Unit: The central unit is the basic part of the computer and includes all the main computer parts. It is the heart of the computer system. It is responsible for executing, or running the software. The software programs are translated into a series of codes made up of 1s to 0s that the CPU can understand. Every code means a certain operation should take place. A CPU has various discrete units to help it in these tasks for example there is an arithmetic
document, editing images, computer games (Kirschner, 2010) and many others. It is defined as a piece of equipment used for moving a cursor on a computer screen (Mac-Millan Dictionary). There are many types of pointing devices nowadays such as mouse, trackball, pointing stick, joystick, touch pad, touch screen, light pen and digitizer tablet. Pointing devices are used depend on the types of task to perform in the computer. For example, joystick is often used to control play games. Digitizer tablet and
Confirmation Bias The human brain is capable of 1016 processes per second, which makes it far more powerful than any computer currently in existence. But that does not mean that our brains do not have major problems and limitations. The calculator can do math thousands of times better than we can, and our memories are often very limited. Moreover, we are subject to cognitive biases, those often unrecognized beliefs that we hold that cause us to make questionable decisions and reach erroneous conclusions
appearance of a standard computer mouse is a small object that contains: two buttons (left and right) which allows a person to “click” and drag, a scroll wheel which can act as another button, a cord and plug. Some of the newer computer mice have a trackball which is there to help scroll faster or for longer documents. The optical mouse has a LED sensor underneath the mouse as pictured below.

"Technology is like fish. The longer it stays on the shelf, the less desirable it becomes." (1) Since the dawn of computers, there has always been a want for a faster, better technology. These needs can be provided for quickly, but become obsolete even quicker. In 1981, the first "true portable computer", the Osborne 1 was introduced by the Osborne Computer Corporation. (2) This computer revolutionized the way that computers were used and introduced a brand new working opportunity. The Osborne
A computer system consists of hardware and software. Hardware is the slang word for the physical components?keyboards, mice, circuit boards, monitors and cables. Hardware needs some maintenance, such as appropriate, safe cleaning, and must be protected from dust and heat. Dust buildup can even cause overheating. Some maintenance, especially moving computers, is best done while the equipment is off. Keep track of your hardware instruction manuals. Use a notebook to keep track of your equipment?serial

Adaptations to computer input devices include hardware options like voice-controlled devices, trackballs, touch screens and adapted keyboards can assist children with special physical needs and make computers and technology more accessible to them. Blind or visually impaired children can use voice activated machines or special Braille keyboards to
Teaching in the 21st century is utilising the many advances of modern technology to assist teachers and students within the learning environment. 21st century learning environments ensure the use of technology within the classrooms, as teachers aren 't the primary providers of information they are more facilitators to help gather information and their roles as a teacher is more to help students understand and learn from their research rather than provide the information to students. As stated by
What is ergonomics? Ergonomics is the science of fitting the job to the worker. When there is a mismatch between the physical requirements of the job and the physical capacity of the worker, work-related musculoskeletal disorders can result. Workers who must repeat the same motion throughout their workday, work in an awkward position use a great deal of force to perform, repeatedly lift heavy objects or face a combination of these risk factors are most likely to develop work-related musculoskeletal

Classifications of Computers According to the U.S. Census "Forty-four million households, or 42 percent, had at least one member who used the Internet at home in 2000" (Home Computers 2). Today, no doubt, even more family members in the United States use computers. Most people are aware of the desktop computers which can be found in the home and in the workplace. What are the different types of computers and what are their purposes? Computers can be classified into three different categories of
Analysis of Virtual Reality The term Virtual Reality (VR) is used by many different people with many meanings. There are some people to whom VR is a specific collection of technologies, that is a Head Mounted Display, Glove Input Device and Audio. Some other people stretch the term to include conventional books, movies or pure fantasy and imagination. However, for purposes of this research, we restrict VR to computer mediated systems. We would define Virtual Reality as a way for humans to visualize
distinct forms of disabled-friendly input devices on a computer, pointing devices and voice recognition. Pointing devices do the same job as a mouse; move the pointer to a certain location on the screen. This equipment comes in different forms, trackballs, oral fixtures, and eye-coordinated input devices are all examples of special pointing devices. The other form of an input device was voice recognition. This form does the job of the keyboard. The user talks into a microphone, and his speech is
Technology is always changing to meet our needs. As a society that relies on technology everyday it is safe to say that from twenty years from now computers will be an even larger part of our lives. Computers have followed a concept called Moore's law, which states that computer speed will double every eighteen months. This means that computers available now are about twice as fast as the fastest ones available eighteen months ago. If computers follow this law, in about twenty years computers will
