A text entry box A multi-line "textarea" text box in a web browser. A text box also called an input box, text field or text entry box, is a control element of a graphical user interface, that should enable the user to input text information to be used by a program.
In this text navigation mode the ‘cursor’, often depicted as a blinking vertical line, appears within the text on-screen. The user can then navigate throughout the text by using the arrow navigation keys to cause the cursor to move; typically changing the cursor's location in increments of character position horizontally and of text line vertically.
The cursor for the Windows Command Prompt (appearing as an underscore at the end of the line). In most command-line interfaces or text editors, the text cursor, also known as a caret, [4] is an underscore, a solid rectangle, or a vertical line, which may be flashing or steady, indicating where text will be placed when entered (the insertion point).
In computer graphics programming, hit-testing (hit detection, picking, or pick correlation [1]) is the process of determining whether a user-controlled cursor (such as a mouse cursor or touch-point on a touch-screen interface) intersects a given graphical object (such as a shape, line, or curve) drawn on the screen.
Now, a line segment labeled with the numbers 1, 2, and 3. From position 3, it takes no steps to the left to stay at 3, so 3 − 0 = 3. It takes 2 steps to the left to get to position 1, so 3 − 2 = 1. This picture is inadequate to describe what would happen after going 3 steps to the left of position 3.
Now the users position can be accounted for. The influence of the angle can be weighted using the exponent. This addition was introduced by Kopper et al. in 2010. [21] The formula reduces to the Shannon form when k = 1. Therefore, this model can be directly compared against the Shannon form of Fitts's law using the F-test of nested models. [22]
A web browser tooltip displayed for hyperlink to HTML, showing what the abbreviation stands for.. The tooltip, also known as infotip or hint, is a common graphical user interface (GUI) element in which, when hovering over a screen element or component, a text box displays information about that element, such as a description of a button's function, what an abbreviation stands for, or the exact ...
One criticism is that because the pointing stick depends on the user's applying pressure, it can cause hand cramps (although this can be partly solved by setting the sensitivity higher and lifting the finger when the pointer is not being moved). Another criticism is that it stresses the index finger and may lead to repetitive strain injury.
