A Fuel Model is a stylized set of fuel bed characteristics used as input for a variety of wildfire modeling applications.
 Wildfire behavior models, such as those of Rothermel, take into account numerous empirical variables.
 While these inputs are important for equation outputs, they are often difficult and time-consuming, if not impossible, to measure for each fuel bed.
 A fuel model defines these input variables for a stylized set of quantitative vegetation characteristics that can be visually identified in the field.
 Depending on local conditions, one of several fuel models may be appropriate.
 As Anderson states “Fuel models are simply tools to help the user realistically estimate fire behavior.
 The user must maintain a flexible frame of mind and an adaptive method of operating to totally utilize these aids".
 Furthermore, depending on the application, the user must choose a fuel model classification system.
 The major classification systems for use in the United States include the National Fire Danger Rating System, the 13 ‘original’ fuel models of Anderson and Albini, the subsequent set of 40 fuels produced by Scott and Burgan, and the Fuel Characteristics Classification System.
State management refers to the management of the state of one or more user interface controls such as text fields, OK buttons, radio buttons, etc. in a graphical user interface.
 In this user interface programming technique, the state of one UI control depends on the state of other UI controls.
 For example, a state managed UI control such as a button will be in the enabled state when input fields have valid input values and the button will be in the disabled state when the input fields are empty or have invalid values.
Merriam-Webster, Incorporated, is an American company that publishes reference books, especially known for its dictionaries.
In computer programming, event-driven programming is a programming paradigm in which the flow of the program is determined by events such as user actions (mouse clicks, key presses), sensor outputs, or messages from other programs/threads.
 Event-driven programming is the dominant paradigm used in graphical user interfaces and other applications (e.g. JavaScript web applications) that are centered on performing certain actions in response to user input.
 This is also true of programming for device drivers (e.g. P in USB device driver stacks)
Skinput is an input technology that uses bio-acoustic sensing to localize finger taps on the skin.
 When augmented with a pico-projector, the device can provide a direct manipulation, graphical user interface on the body.
 The technology was developed by Chris Harrison, Desney Tan, and Dan Morris, at Microsoft Research's Computational User Experiences Group.
 Skinput represents one way to decouple input from electronic devices with the aim of allowing devices to become smaller without simultaneously shrinking the surface area on which input can be performed.
 While other systems, like SixthSense have attempted this with computer vision, Skinput employs acoustics, which take advantage of the human body's natural sound conductive properties (e.g., bone conduction).
 This allows the body to be annexed as an input surface without the need for the skin to be invasively instrumented with sensors, tracking markers, or other items.
In computer programming, an input kludge is type of failure in software (an anti-pattern) where simple user input is not handled.
 For example, if a computer program accepts free text input from the user, an "ad hoc" algorithm will mishandle many combinations of legal and illegal input strings.
 Input kludges are usually difficult for a programmer to detect in a unit test, but very easy for the end user to find.
 The evidence exists that the end user can easily crash software that fails to correctly handle user input.
 Indeed, the buffer overflow security hole is an example of the problems caused.
A magic string is an input that a programmer believes will never come externally and which activates otherwise hidden functionality.
 A user of this program would likely provide input that gives an expected response in most situations.
 However, if the user does in fact innocently provide the pre-defined input, invoking the internal functionality, the program response is often quite unexpected to the user (thus appearing "magical").
User advocacy has several definitions.
 One is that user advocacy is the practice of using designated spokespeople to facilitate interaction between users and designers of the products they use.
 Another more broadly defines user advocacy as the practice of advocating for the user, regardless of whether one is a user, designer, developer, researcher, manager, etc.
 User advocates typically may suspend their own personal or functional point of view, and attempt to see the product through the eyes of, and the experience of, the user of that product.
 The ability to take on the user's point of view, without personal judgement or bias, allows the advocate to see things as the user might see them, enabling them to ultimately make observations and perhaps recommendations to improve the user experience.
 Similarly, some user advocates will take a neutral, scientific point of view, and will observe and collect data from users that will suggest that the product and/or user experience could be changed or improved in a way that users would prefer or benefit from.
 User advocates may be scientists or engineers who use the scientific method to make improvements that result in increased ease of use, time savings, improved levels of user satisfaction, or other user-centered metrics.
In computing, DirectInput is a legacy Microsoft API for collecting input from a computer user, via input devices such as the mouse, keyboard, joystick or other game controllers.
 It also provides a system for "action mapping," which allows the user to assign specific actions within a game to the buttons and axes of the input devices.
 Additionally it handles "haptic feedback" (input/output) devices.
 Microsoft introduced a new input library called XInput specifically for the Xbox 360 controller.
The term interactive course typically describes material of an educational nature delivered in a format which allows the user to directly impact the materials' content, pace, and out-come.
 Interactive, as defined by Merriam-Webster online dictionary, is "involving the actions or input of a user"
