Scientists Say: Haptic

0
engineering: The field of research that uses math and science to solve practical problems.

field: An area of study, as in: Her field of research is biology. Also a term to describe a real-world environment in which some research is conducted, such as at sea, in a forest, on a mountaintop or on a city street. It is the opposite of an artificial setting, such as a research laboratory. (in physics) A region in space where certain physical effects operate, such as magnetism (created by a magnetic field), gravity (by a gravitational field), mass (by a Higgs field) or electricity (by an electrical field).

force: Some outside influence that can change the motion of a body, hold bodies close to one another, or produce motion or stress in a stationary body.

information: (as opposed to data) Facts provided or trends learned about something or someone, often as a result of studying data.

physical: (adj.) A term for things that exist in the real world, as opposed to in memories or the imagination. It can also refer to properties of materials that are due to their size and non-chemical interactions (such as when one block slams with force into another).

pressure: Force applied uniformly over a surface, measured as force per unit of area.

receptor: (in biology) A molecule in cells that serves as a docking station for another molecule. That second molecule can turn on some special activity by the cell.

smartphone: A cell (or mobile) phone that can perform a host of functions, including search for information on the internet.

sound wave: A wave that transmits sound. Sound waves have alternating swaths of high and low pressure.

tactile: An adjective that describes something that is or can be sensed by touching.

virtual: Being almost like something. An object or concept that is virtually real would be almost true or real — but not quite. The term often is used to refer to something that has been modeled — by or accomplished by — a computer using numbers, not by using real-world parts. So a virtual motor would be one that could be seen on a computer screen and tested by computer programming (but it wouldn’t be a three-dimensional device made from metal). (in computing) Things that are performed in or through digital processing and/or the internet. For instance, a virtual conference may be where people attended by watching it over the internet.

virtual reality: A three-dimensional simulation of the real world that seems very realistic and allows people to interact with it. To do so, people usually wear a special helmet or glasses with sensors.

wave: A disturbance or variation that travels through space and matter in a regular, oscillating fashion.
