Footmouse
A footmouse (or foot mouse) is a type of computer mouse that gives the users the ability to move the cursor and click the mouse buttons with their feet. It is primarily used by users with disabilities or with high-back or neck problems. It is also promoted as a way to prevent such problems in the future and as a means to increase productivity by not having to move one's hand between the keyboard and mouse. Types There are about ten types of footmouse. Not all of them are commercially available. Some specialized companies design their own foot controlled mouse for disabled people. The main difference between the different types of footmouse is a flat pedal which slides or a pedal which tilts. There also exists a mouse adapter which converts a conventional mouse to a footmouse that slides and horizontally tilts to one side. A footmouse that uses sliding can be a slipper with a mouse connected to it, or a special frame in which a pedal can move around. Also a tiny magnet or other l ...

Mouse (computer)
A computer mouse (plural mice; also mouses) is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of the pointer (called a cursor) on a display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was done by Doug Engelbart in 1968 as part of the Mother of All Demos. Mice originally used two separate wheels to directly track movement across a surface: one in the x-dimension and one in the Y. Later, the standard design shifted to use a ball rolling on a surface to detect motion, in turn connected to internal rollers. Most modern mice use optical movement detection with no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range radio communication with the connected system. In addition to moving a cursor, comput ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cursor (computers)
In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to input, such as a text cursor or a mouse pointer. Etymology ''Cursor'' is Latin for 'runner'. A cursor is a name given to the transparent slide engraved with a hairline used to mark a point on a slide rule. The term was then transferred to computers through analogy. On 14 November 1963, while attending a conference on computer graphics in Reno, Nevada, Douglas Engelbart of Augmentation Research Center (ARC) first expressed his thoughts to pursue his objective of developing both hardware and software computer technology to ''augment'' human intelligence by pondering how to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data, and envisioned something like the cursor of a mouse he initially called a ''bug'', which, in a 3-point form, could have a "drop point and 2 orthogonal wheels". He w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disability
Disability is the experience of any condition that makes it more difficult for a person to do certain activities or have equitable access within a given society. Disabilities may be Cognitive disability, cognitive, Developmental disability, developmental, Intellectual disability, intellectual, mental disorder#Disability, mental, physical disability, physical, Sense, sensory, or a combination of multiple factors. Disabilities can be Birth defect, present from birth or can be acquired during a person's lifetime. Historically, disabilities have only been recognized based on a narrow set of criteria—however, disabilities are not binary and can be present in unique characteristics depending on the individual. A disability may be readily visible, or Invisible disability, invisible in nature. The United Nations Convention on the Rights of Persons with Disabilities defines disability as including: Disabilities have been perceived differently throughout history, through a variety of ...

Neck
The neck is the part of the body in many vertebrates that connects the head to the torso. It supports the weight of the head and protects the nerves that transmit sensory and motor information between the brain and the rest of the body. Additionally, the neck is highly flexible, allowing the head to turn and move in all directions. Anatomically, the human neck is divided into four compartments: vertebral, visceral, and two vascular compartments. Within these compartments, the neck houses the cervical vertebrae, the cervical portion of the spinal cord, upper parts of the respiratory and digestive tracts, endocrine glands, nerves, arteries and veins. The muscles of the neck, which are separate from the compartments, form the boundaries of the neck triangles. In anatomy, the neck is also referred to as the or . However, when the term ''cervix'' is used alone, it often refers to the uterine cervix, the neck of the uterus. Therefore, the adjective ''cervical'' ...

Computer Keyboard
A computer keyboard is a built-in or peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or Push-button, keys to act as Mechanical keyboard, mechanical levers or Electronic switching system, electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input device, input method for computers since the 1970s, supplemented by the computer mouse since the 1980s, and the touchscreen since the 2000s. Keyboard keys (buttons) typically have a set of characters Engraving, engraved or Printing, printed on them, and each press of a key typically corresponds to a single written symbol. However, producing some symbols may require pressing and holding several keys simultaneously or in sequence. While most keys produce character (computing), characters (Letter (alphabet), letters, Numerical digit, numbers or symbols), other keys (such as the escape key) can prompt the ...

Graphics Tablet
A graphics tablet (also known as a digitizer, digital graphic tablet, pen tablet, drawing tablet, external drawing pad or digital art board) is a computer input device that enables a user to hand draw or paint images, animations and graphics, with a special pen-like stylus (computing), stylus, similar to the way a person draws pictures with a pencil and paper by hand. Graphics tablets may also be used to capture data or handwritten signatures. They can also be used to trace an image from a piece of paper that is taped or otherwise secured to the tablet surface. Capturing data in this way, by tracing or entering the corners of linear Polygonal chain, polylines or shapes, is called digitizing. The device consists of a rough surface upon which the user may "draw" or trace an image using the attached stylus (computing), stylus, a pen-like drawing apparatus. The image is shown on the computer computer display, monitor, though some graphic tablets now also incorporate an LCD screen f ...

Sewing Machine
Diagram of a modern sewing machine Animation of a modern sewing machine as it stitches A sewing machine is a machine used to sew fabric and materials together with thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing work performed in clothing companies. Since the invention of the first sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790, the sewing machine has greatly improved the efficiency and productivity of the clothing industry. Home sewing machines are designed for one person to sew individual items while using a single stitch type at a time. In a modern sewing machine, the process of stitching has been automated, so that the fabric easily glides in and out of the machine. Early sewing machines were powered by either constantly turning a flywheel handle or with a foot-operated treadle mechanism. Electrically-powered machines were later introduced. Industria ...

Medical Transcription
Medical transcription, also known as MT, is an allied health profession dealing with the process of transcribing voice-recorded medical reports that are dictated by physicians, nurses and other healthcare practitioners. Medical reports can be voice files, notes taken during a lecture, or other spoken material. These are dictated over the phone or uploaded digitally via the Internet or through smart phone apps. History Medical transcription as it is currently known has existed since the beginning of the 20th century when standardization of medical records and data became critical to research. At that time, medical stenographers recorded medical information, taking doctors' dictation in shorthand. With the creation of audio recording devices, it became possible for physicians and their transcribers to work asynchronously. Over the years, transcription equipment has changed from manual typewriters, to electric typewriters, to word processors, and finally, to computers. Storage ...
