The first human–computer interface application of Fitts's law was by Card, English, and Burr, [11] who used the index of performance (IP), interpreted as 1 ⁄ b, to compare performance of different input devices, with the mouse coming out on top compared to the joystick or directional movement keys. [11]
Tool-assisted speedrunning relies on the same series of inputs being played back at different times always giving the same results. The emulation must be deterministic with regard to the saved inputs, and random seeds must not change. Otherwise, a speedrun that was optimal on one playback might not even complete it on a second playback.
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]
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.
Whereas Microsoft mice and Microsoft keyboards were previously controlled from two separate programs – IntelliPoint and IntelliType – the Mouse and Keyboard Center is responsible for both kinds of devices. 32- and 64-bit versions of the software are available, and the program integrates with Windows 8 and above's "Modern UI" interface.
Snap, [6] or jounce, [2] is the fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time. [4] Equivalently, it is the second derivative of acceleration or the third derivative of velocity, and is defined by any of the following equivalent expressions: = ȷ = = =.
The term tractive effort is often qualified as starting tractive effort, continuous tractive effort and maximum tractive effort.These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction (μ) between the driving wheels and supporting surface, and the weight applied to the ...
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 ...
