As mentioned later in this article, pointing devices have different possible states. Examples for these states are out of range, tracking or dragging. Examples. a computer mouse is an indirect, relative, isotonic, position-control, translational input device with two degrees of freedom (x, y position) and two states (tracking, dragging).
Strafing in video games is a maneuver which involves moving a controlled character or entity sideways relative to the direction it is facing. This may be done for a variety of reasons, depending on the type of game; for example, in a first-person shooter, strafing would allow one to continue tracking and firing at an opponent while moving in another direction.
P (pointing to a target on a display with a mouse): this time differs depending on the distance to the target and the size of the target, [6] but is held constant. A mouse click is not contained and counts as a separate K operation.
Windows also has full support for multiple input/mouse configurations for multi-user environments. Starting with Windows XP, Microsoft introduced an SDK for developing applications that allow multiple input devices to be used at the same time with independent cursors and independent input points. However, it no longer appears to be available. [110]
When there are two users, like in the picture example, the two simultaneous dual input actions would require two “cursors” in the operating system to function. If one of the users also has a mouse connected to their display there is a risk that the second user would interrupt the first user by moving the mouse cursor.
However, open-loop control is very useful and economic for well-defined systems where the relationship between input and the resultant state can be reliably modeled by a mathematical formula. For example, determining the voltage to be fed to an electric motor that drives a constant load, in order to achieve a desired speed would be a good ...
In control system theory, and various branches of engineering, a transfer function matrix, or just transfer matrix is a generalisation of the transfer functions of single-input single-output (SISO) systems to multiple-input and multiple-output (MIMO) systems. [1] The matrix relates the outputs of the system to its inputs.
Two major groups of multimodal interfaces have merged, one concerned in alternate input methods and the other in combined input/output. The first group of interfaces combined various user input modes beyond the traditional keyboard and mouse input/output, such as speech, pen, touch, manual gestures, [21] gaze and head and body movements.
