Input device a hardware device that sends information into the cpu without any input devices a computer would simply be a display device and not allow users to interact with it, much like a tv. It - chapt 3 chapt 3 study play peripheral device a computer input device that uses a set of keys to put data into the computer includes a variety of devices and methods that enable physically challenged computer users to control their computer and provide input electronic pen stylus. Input devices, processing and output devices input devices, like a keyboard, allow us to put raw data in a computer which it processes to produce outputs input devices can be manual or automatic. Once an exercise in frustration, using a computer is well within reach of the blind and physically disabled with the help of these new and updated accessibility tools. I) discuss input and output devices for disabled computer users people are diverse - some people are not able to use the 'standard' devices that you or i use in our every-day lives and so, devices have been specially developed to allow for these differences.

Unlike input devices like keyboards and mice that let you send data to your computer, you use output devices to receive information back from your computer in a way you can read, see or hear. A specialised output device is an output device which is adapted for a particular purpose, such as use by a person who is disabled for example: computers which can speak back the words that have. (f) braille input and output devices braille keyboards allow visually impaired users to enter data into a computer whilst a refreshable braille display converts the screen display to a braille equivalent. Input devices and interaction techniques are the human operator's baton they set, constrain, and elicit a spectrum of actions and responses, and in a large way inject a personality on the entire human-machine system.

Thanks to creative minds that build assistive technology devices, physically challenged people do not have to give up computing computers work by accepting input from people and providing output. Alternative input devices keystroke modification and mouse emulation typically provide combinations of one or more of the following: execution of multiple-keystroke commands (such as control-x) serially rather than simultaneously manipulation of the mouse via the keyboard alternatives to clicking and/or holding mouse buttons and visible and/or audible feedback for keystrokes. What are the types of input and/or output devices designed for physically challenged computer users i am writing a 450 word research paper and need a web site to substantiate any findings follow.

A computer system may need to be adapted before it can be accessible to a user who is physically disabled assistive technology is the term used to describe the hardware (and software) that can help someone with a special need to use a computer. Invited audience members will follow you as you navigate and present people invited to a presentation do not need a prezi account this link expires 10 minutes after you close the presentation a maximum of 30 users can follow your presentation learn more about this feature in our knowledge base article. These natural-language user interface systems now power everything from hands-free computing for the disabled to in-car voice commands to mobile device virtual assistants like siri, cortana, and. Input devices include the keyboard, pointing devices, scanners and reading devices, digital cameras, audio and video input devices for physically challenged use mouse the mouse is an input device that is used to control the movement of the pointer on the screen and to make selections from the screen she top of the mouse has one to four buttons.

What are some input/and or output devices designed for physically challenged computer users is there a web site that i can go to, to get more information thanks follow 3 answers 3 report abuse a lot of this stuff is custom made per the user needs. Alternative output devices screen magnifiers enlarge the information displayed on the computer screen in a range of magnifications and a variety of fonts the magnifier my have the ability to create a large, scrolling virtual screen, or may only magnify the portion of the display near the mouse pointer. Devices for disabled users there are a number of devices that have been adapted for disabled users to make it easier for them to use computers devices like large print or braille keyboards help visually impaired users enter data into computers. Quick answer some input devices for physically challenged computer users include specialized keyboards, mice that are operated only with a thumb, voice recognition software and tools that provide keyboard and mouse input via blowing air into a device.

Put and output devices (mainly existing assistive technology like braille, a novel tactile display and special input devices for physically disabled users were used) could be used to display the interface. Output devices are the pieces of equipment that show what you inputsome cannot be used by people with disabilities so there are alternatives input devices people with disabilities may need more specialized input devices. Input and output devices thumb mouse and specialized keyboards allow the physically challenged to input information into computers voice recognition software lets handicapped users speak computer input commands voice synthesizers allow blind users to receive computer output. Assistive technology for computer system input people with physical disabilities effecting the use of their hands and fingers typically have difficulty utilizing a standard mouse or keyboard thus requiring computer access at to input information into a computer they provide the user with a rigid pointing device that, due to the user.

  • The designation of a device as either input or output depends on perspective mouse and keyboards take physical movements that the human user outputs and convert them into input signals that a computer can understand the output from these devices is the computer's input.
  • In section 21 we will focus on manual input devices and then move onto direct input devices in section 22 some scanners are 'hand held' which means the user physically moves the scanner across the image in order to send a copy to a computer # input/output devices main menu next - direct input devices.
  • An output device is any device used to send data from a computer to another device or user most computer data output that is meant for humans is in the form of audio or video thus, most output devices used by humans are in these categories.

User agents should offer redundant input and output mechanisms for those devices that are supported for example, if a user agent supports keyboard and mouse input, users should be able to interact with all features using either the keyboard or the mouse. Input and output devices for disabled users some disabilities mean that the input devices themselves need to be placed in convenient ways for the person for example, someone with physical problems may need to have the input devices close by. A terminal consists of an input device, an output device, and a communications link to the main computer most commonly, a terminal has a keyboard for an input device and a screen for an output device, although there are many variations on this theme.
