tilt

Tilt is a term used to describe a deviation from vertical orientation or an angular displacement around a horizontal axis. In general use, tilt can refer to how an object, device, or image is slanted relative to a reference direction. The precise meaning depends on the context and the reference used to measure the angle.

In geometry and earth sciences, tilt describes the inclination of a line, plane, or rock layer. The tilt angle is the angle between the object and a reference plane, usually the horizontal. In geology this concept helps describe whether beds are dipping, horizontal, or overturned due to tectonic forces.

In photography and cinematography, tilt denotes a camera movement about a horizontal axis, moving the lens up or down. This is distinct from a pan, which rotates around a vertical axis. Tilt-shift lenses leverage this motion to control perspective and focus characteristics.

In machinery and consumer devices, tilt appears in adjustable components such as tilt steering wheels and tilt mechanisms for displays, enabling users to set a comfortable viewing or operating angle.

In civil engineering and architecture, tilt can refer to a structure that leans or subsides from vertical because of foundation settlement, soil conditions, or damage. Monitoring tilt is important for safety, maintenance, and remediation planning.

In gaming and gambling slang, tilt describes a temporary emotional upset or frustration that impairs judgment and performance, often following losses or adverse events.

Medical contexts include tilt-table testing, a procedure that assesses autonomic function by evaluating heart rate and blood pressure response when a patient is tilted to an upright position.
