Device Based Controls Pdf Computer Science Human Machine Interaction Key steps include developing navigation, selecting windows and controls, writing clear text, providing feedback, testing, and considering users, tasks, environments, and hardware when choosing controls. Guidelines for selecting the proper device based control — provide touch screens under the following conditions: • the opportunity for training is minimal. • targets are large, discrete, and spread out.
5 Device Based Controls Pdf Provide an alternative pointing device for graphical or drawing tasks. the following are some suggested best uses: • mouse—pointing, selecting, drawing, and dragging. • joystick—selecting and tracking. • trackball—pointing, selecting and tracking. • touch screen—pointing and selecting. Each device driver is tailored to a particular device type and handles the translation of generic commands from the operating system into instructions that the device can understand. Arectangular or dome shaped, movable, desktop control containing from one to three buttons used to manipulate objects and information on the screen. movement of screen pointer mimics the mouse movement. direct relationship between hand and pointer movement in terms of direction, distance, and speed. permits a comfortable hand resting position. Object separation should be at least 1⁄8 inch. provide visual feedback in response to activation. auditory feedback may also be appropriate. when the consequences are destructive, require confirmation after selection to eliminate inadvertent selection. provide an instructional invitation to begin using. light pen description.
