Absolute: report position with regard to an origin e.g. data tablet, touch screen Relative: report position w.r.t. their former position e.g. mouse, joystick, Wii remote controller. Computer Graphics - Chapter 3 Input and Interaction In C input and output are done using, printf, scanf, getchar, and putchar. In computer graphics, the use of logical devices is slightly more complex. This is because the forms that input can take ar e more varied than the strings of bits. CSCA Computing Basics 5. Output Devices Monitor. • The device which displays computer output. • The monitor displays the video and graphics information generated by the computer through the video card. • Monitors are very similar to televisions but usually display information at a much higher resolution. Track Ball. Track ball is an input device that is mostly used in notebook or laptop computer, instead of a mouse. This is a ball which is half inserted and by moving fingers on ball, pointer can be moved. Since the whole device is not moved, a track ball requires less space than a mouse. Input is any data or instructions entered into the memory of a computer. An input device is any hardware component that allows a user to enter data and instructions into a computer. The following is a list of the most common input devices which are nowadays found in a computer system. QWERTY Keyboard glossary pg. The Cubic Mouse (shown in the figure on the right) is an input device developed at GMD that allows users to intuitively specify three-dimensional coordinates in graphics applications. The device consists of a box with three perpendicular rods passing through the center and buttons for additional input. Computer Graphics Farhana Bandukwala, PhD Lecture 3: Graphics System.
