EXERCISE 2

Post  Julie Ann R. Monteroso on Sun Mar 13, 2011 1:49 am

Input is concerned with recording and entering data into computer system and issuing instruction to the computer. In order to interact with computer systems effectively, users must be able to communicate their interaction in such a way that the machine can interpret them. Therefore, input devices can be defined as: a device that, together with appropriate software, transforms information from the user into data that acomputer application can process.
Here are some examples of computer input devices:

Keyboard - The keyboard is a way to input letters or numbers into different applications or programs. A keyboard also has special keys that help operate the computer.

Mouse - The mouse is used to open and close files, navigate web sites, and click on a lot of commands (to tell the computer what to do) when using different applications.

Joystick - A joystick is used to move the cursor from place to place, and to click on various items in programs. A joystick is used mostly for computer games.

Touch Screen - A touch screen is a computer screen or other screen that you can touch with your finger to enter information. Examples of touch screens include a smart board, a microwave, a dishwasher, or an ATM at a bank.

Drawing Tablet - A drawing tablet is similar to a white board, except you use a special pen to write on it and it's connected to the computer. Then the word or image you draw can be saved on the computer.

Microphone - A microphone is used to record sound. The sound is then saved as a sound file on the computer.

Exercise 2 Pick a couple of computer input devices that you are aware of (joystick, light pen, touch screen, trackball, eye gaze, data glove, etc.) and note down how each has different attributes that support certain forms of interaction. You ought to know a little about all of these devices - if you do not, research them.

An input device that looks similar to a control device you would find on an arcade game at your local arcades. A joystick allows an individual to easily move an object in a game such as navigating a plane in a flight simulator. The picture to the right is of the LogitechFreedom 2.4 joystick and an example of what a Joystick may look like.

One of the main input devices used on a computer, a PC's keyboard looks very similar to the keyboards of electric typewriters, with some additional keys. Below is a graphic of the Saitek Gamers' keyboard with indicators pointing to each of the major portions of the keyboard.

Sometimes abbreviated as mic, a microphone is a hardware peripheral originally invented by Emile Berliner in 1877 that allows computer users to input audio into their computers. To the right is a visual example of a USB headset from Logitech with a microphone. A popular solution for computer gaming and sound trips.

A hardware input device that was invented by Douglas Engelbart in 1963, who at the time was working at the Stanford Research Institute, which was a think tank sponsored by Stanford University. The mouse allows an individual to control a pointer in a graphical user interface (GUI). Utilizing a mouse a user has the ability to perform various functions such as opening a program or file and does not require the user to memorize commands, like those used in a text-based command line environment such as MS-DOS. To the right is a picture of a MicrosoftIntelliMouse and is an example of what a computer mouse may look like.

The Mouse was originally referred to as an X-Y Position Indicator for a Display System. Xerox later applied the mouse to its revolutionary Alto computer system in 1973. However, because of Alto's unfortunate success, it was first widely used in the AppleLisa computer. Today, a pointing device is found on virtually every computer.

Short for Musical Instrument Digital Interface, MIDI is a standard for digitally representing and transmitting sounds that was first developed in the 1980s. The MIDI sound is played back through the hardware device or computer either through a synthesized audio sound or a waveform stored on the hardware device or computer. The quality of how MIDI sounds when played back by the hardware device or computer depends upon that device's capability. Generally, most computer sound cards will have a MIDI port as shown in the picture on this page that allows for several musical instrument devices to be connected to the computer such as a MIDI keyboard or a synthesizer. Before connecting any of these devices to the computer, you will need to purchase a separate cable, which takes the MIDI/Game port connection into the standard 5-pin DIN midi connector or a USB to MIDI converter.

Hardware input device that allows a user to take an image or text and convert it into a digital file, allowing the computer to read or display the scanned object. A scanner is commonly connected to a computer USB, Firewire, Parallel or SCSI port. To the right is a picture and an example of a flatbed photo scanner, the Epson V300.
Other scanners include: sheetfed scanner, which is a scanner that scans paper fed into it, handheld scanner, which is a scanner that is held and drag over a page to scan it, and a card scanner, which is a small scanner capable of scanning business cards.

Lines of different widths and sizes representing data, that when read will determine what the scanned object is. Bar codes are often used to help organize and index information or prices about an object. Barcodes used by the U.S. postal service that helps speed the delivery of mail is another perfect example of how a barcode could be used. In the picture to the right, is an example of what a barcode for an address may look like.
Barcode reader or scanner - also known as a point of sale (POS) scanner is a hardware device capable of reading a barcode and printing out the details of the product or logging that product into a database. A perfect example of a barcode reader is a super market barcode scanner that reads and logs the price of a product.
Barcode printers - A hardware device capable of printing out adhesive barcodes that can be attached to a product. This helps identify the product or a company keep track of its inventory.

A camera that stores the pictures or video it takes in electronic format instead of to film. There are several features that make digital cameras a popular choice when compared to film cameras. First, the feature often enjoyed the most is the LCD display on the digital camera. This display allows users to view photos or video after the picture or video has been taken, which means if you take a picture and don't like the results, you can delete it; or if you do like the picture, you can easily show it to other people. Another nice feature with digital cameras is the ability to take dozens, sometimes hundreds of different pictures. To the right is a picture of theCasio QV-R62, a 6.0 Mega Pixel digital camera used to help illustrate what a digital camera may look like.

Digital cameras have quickly become the camera solution for most users today as the quality of picture they take has greatly improved and as the price has decreased. Many users however are hesitant in buying a digital camera because of the inability of getting their pictures developed. However, there are several solutions in getting your digital pictures developed. For example, there are numerous Internet companies capable of developing your pictures and send you your pictures in the mail. In addition, many of the places that develop your standard cameras film now have the ability to develop digital pictures if you bring them your camera, memory stick, or pictures on CD.

More commonly known as a game paddle or gamepad, a paddle is an input device commonly used with games that may contain various buttons used to steer and utilize different options in a game. All console game systems utilize a paddle or gamepad for control. To the right is a picture and an example of a game paddle used with the Atari 2600. The term paddle may also be used to describe various handheld devices that are capable of controlling a function on a computer or electronic device.

Remote control – are devices used to issue commands from a distance to televisions or other electronics such as stereo systems, DVD players and the like. Most of these remotes communicate to their respective devices via infrared (IR) signals and a few via radio signals.

Laser Mouse - In computing, a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. The mouse's motion typically translates into the motion of a cursor on a display, which allows for fine control of a graphical user interface.

Light pen - a computer input device in the form of a light-sensitive wand used in conjunction with a computer's CRT TV set or monitor. It allows the user to point to displayed objects, or draw on the screen, in a similar way to a touch screen but with greater positional accuracy. A light pen can work with any CRT-based display, but not with LCD screens (though Toshiba and Hitachi displayed a similar idea at the "Display 2006" show in Japan[1]), projectors and other display devices.

Data glove - an interactive device, resembling a glove worn on the hand, which facilitates tactile sensing and fine-motion control in robotics and virtual reality . Data gloves are one of several types of electromechanical devices used in haptics applications.Tactile sensing involves simulation of the sense of human touch and includes the ability to perceive pressure, linear force, torque, temperature, and surface texture. Fine-motion control involves the use of sensors to detect the movements of the user's hand and fingers, and the translation of these motions into signals that can be used by a virtual hand (for example, in gaming ) or a robotic hand (for example, in remote-control surgery).

You ought to know a little about all of these devices - if you do not, research them..


A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick.

Im not so popular about any weird device and so, It just happen that i encounter playing video games in computer using "Joystick", at that time were playing "NEED FOR SPEED" and uses the JOYSTICK as a controller. It really makes a Difference after all, the excitement arouses for it feels like a Pedal to the car you are riding to. It was fun to play with, the controller communicates with the computer using the analog response, and was read accordingly with the computer.


The Wii Remote (Wii, Uī Rimokon?), sometimes unofficially nicknamed "Wiimote", is the primary controller for Nintendo's Wii console. A main feature of the Wii Remote is its motion sensing capability, which allows the user to interact with and manipulate items on screen via gesture recognition and pointing through the use of accelerometer and optical sensor technology. Another feature is its expandability through the use of attachments. The attachment bundled with the Wii console is the Nunchuk, which complements the Wii Remote by providing functions similar to those in gamepad controllers. Some other attachments include the Wii Classic Controller, Wii Zapper, and the Wii Wheel, originally used for Mario Kart.

The latest device I use to experienced with my nephews is the WII Remote, it is very handy and unique to any other type of Controllers, it is a Motion Sensored device attached with Nunchuk that will allow to act as a gamepad Controller to the game. It was very fun, playing Table Tennis that its likely your the one holding the racket and Force it to your oponent. Truly, High - Tech device adds more fun with responds to Computer Games.

JOYSTICK

A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick.

The joystick has been the principal flight control in the cockpit of many aircraft, particularly military fast jets, either as a center stick or side-stick.

Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras and zero turning radius lawn mowers. Miniature finger-operated joysticks have been adopted as input devices for smaller electronic equipment such as mobile phones.



LIGHT PEN

A light pen is a computer input device in the form of a light-sensitive wand used in conjunction with a computer's CRT TV set or monitor. It allows the user to point to displayed objects, or draw on the screen, in a similar way to a touch screen but with greater positional accuracy. A light pen can work with any CRT-based display, but not with LCD screens (though Toshiba and Hitachi displayed a similar idea at the "Display 2006" show in Japan[1]), projectors and other display devices.

A light pen is fairly simple to implement. Just like a light gun, a light pen works by sensing the sudden small change in brightness of a point on the screen when the electron gun refreshes that spot. By noting exactly where the scanning has reached at that moment, the X,Y position of the pen can be resolved. This is usually achieved by the light pen causing an interrupt, at which point the scan position can be read from a special register, or computed from a counter or timer. The pen position is updated on every refresh of the screen.




MOUSE


In computing, a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. It sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features that can add more control or dimensional input. The mouse's motion typically translates into the motion of a cursor on a display, which allows for fine control of a graphical user interface.




CAMERAS


A camera is a device that records/stores images. These images may be still photographs or moving images such as videos or movies. The term camera comes from the camera obscura (Latin for "dark chamber"), an early mechanism for projecting images. The modern camera evolved from the camera obscura.

Cameras may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A camera generally consists of an enclosed hollow with an opening (aperture) at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. A majority of cameras have a lens positioned in front of the camera's opening to gather the incoming light and focus all or part of the image on the recording surface. Most 20th century cameras used photographic film as a recording surface, while modern ones use an electronic camera sensor. The diameter of the aperture is often controlled by a diaphragm mechanism, but some cameras have a fixed-size aperture.

Remote control – supports certain appliances or machines, can easily be used by any people, can easily interact with the machine. Commonly, remote controls are Consumer IR devices used to issue commands from a distance to televisions or other consumer electronics such as stereo systems, DVD players and dimmers. Remote controls for these devices are usually small wireless handheld objects with an array of buttons for adjusting various settings such as television channel, track number, and volume. In fact, for the majority of modern devices with this kind of control, the remote contains all the function controls while the controlled device itself only has a handful of essential primary controls. Most of these remotes communicate to their respective devices via infrared (IR) signals and a few via radio signals.

Laser Mouse - In computing, a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons.

The mouse's motion typically translates into the motion of a cursor on a display, which allows for fine control of a graphical user interface. With Laser mouse, one doesn’t need a mousepad in order for it to function well.

An input device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system (such as a computer). Input and output devices make up the hardware interface between computer as a scanner or 6DOF controller.
These could gradually effect the usual behavior of the user to the keyboard.
In a Qwerty Keyboard, the arrangement of keys was chosen in order to reduce the incidence of keys jamming in the manual typewriters of the time rather than because of any optimal arrangement for typing. For example, the letters ‘s’, ,t, and ‘h’ are far apart even though they are far apart even though they are frequently used together. Alphabetic keyboard, are used in some pocket electronic personal organizers, perhaps because the layout looks simpler tousle than the QWERTY one. Also, it dissuades people from attempting to use their touchtyping skills on a very small keyboard and hence avoids criticisms of difficulty of use.
Pointing Devices
A pointing device is any human interface device that allows a user to input spatial data to a computer. In the case of mice and touch screens, this is usually achieved by detecting movement across a physical surface. Analog devices, such as 3D mice, joysticks, or pointing sticks, function by reporting their angle of deflection. Movements of the pointing device are echoed on the screen by movements of the cursor, creating a simple, intuitive way to navigate a computer's GUI.
Composite Devices
Input devices, such as buttons and joysticks, can be combined on a single physical device that could be thought of as a composite device. Many gaming devices have controllers like this. Technically mice are composite devices, as they both track movement and provide buttons for clicking, but composite devices are generally considered to have more than two different forms of input.

You ought to know a little about all of these devices - if you do not, research them.


Touch Screens

Touch Screens allow you to use your finger to touch the screen and choose objects. A special computer monitor or a monitor fitted with special hardware is necessary to provide touch screen capabilities.

Game Controllers

Game controllers are specialized input devices designed to be used when playing video games. They are typically connected to a game console or computer by means of a wire, cord or nowadays, by means of wireless connection Game controllers usually have several buttons that perform different related functions in video games and an analog stick that controls character movement..Game controllers include gamepad, paddle, trackball, joystick, throttle quadrant, steering wheel, yoke, pedals, light guns and many more.

trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down mouse with an exposed protruding ball. The user rolls the ball with the thumb, fingers, or the palm of the hand to move a cursor. Large tracker balls are common on CAD workstations for easy precision. Before the advent of the touchpad, small trackballs were common on portable computers, where there may be no desk space on which to run a mouse. Some small thumbballs clip onto the side of the keyboard and have integral buttons with the same function as mouse buttons. The trackball was invented by Tom Cranston and Fred Longstaff as part of the Royal Canadian Navy's DATAR system in 1952,[1] eleven years before the mouse was invented. This first trackball used a Canadian five-pin bowling ball.

Eyegaze Edge is an FDA- approved communication and control system for people with complex physical disabilities. The system is operated entirely with the eyes. By looking at control keys displayed on a screen, a person can synthesize speech, control his environment (lights, call bells, etc.), type, run computer software, operate a computer mouse, and access the Internet and e-mail. Eyegaze Edge Systems are being used to write books, attend school and enhance the quality of life of people with disabilities all over the world. it is usually used at Detailed Medical and Technical Information with complete discussions of eye control, eye conditions and diseases, positioning, possible medication side effects, mental abilities that may have an effect, and the likelihood that the Eyegaze Edg can be used depending on the person's medical diagnosis.

Webcam

A webcam is a video camera which feeds its images in real time to a computer or computer network, often via USB, ethernet or Wi-Fi. Webcams are used as security cameras. Webcams can be used to take Video clips and still pictures. Special software can use the video stream from a webcam to assist or enhance a user's control of applications and games.
