Algiers putsch of 1961The Algiers putsch (Putsch d'Alger or Coup d'État d'Alger), also known as the Generals' putsch (Putsch des généraux), was a failed coup d'état intended to force French President Charles de Gaulle not to abandon French Algeria, along with the resident European community and pro-French Muslims. Organised in French Algeria by retired French Army generals Maurice Challe (former commander-in-chief in French Algeria), Edmond Jouhaud (former Inspector General of the French Air Force), André Zeller (former Chief of Staff of the French Army) and Raoul Salan (former commander-in-chief in French Algeria), it took place from the afternoon of 21 to 26 April 1961 in the midst of the Algerian War (1954–1962).
Algerian WarThe Algerian War (also known as the Algerian Revolution or the Algerian War of Independence) was a major armed conflict between France and the Algerian National Liberation Front (Front de Libération Nationale – FLN) from 1954 to 1962, which led to Algeria winning its independence from France. An important decolonization war, it was a complex conflict characterized by guerrilla warfare and war crimes. The conflict also became a civil war between the different communities and within the communities.
Interaction designInteraction design, often abbreviated as IxD, is "the practice of designing interactive digital products, environments, systems, and services." While interaction design has an interest in form (similar to other design fields), its main area of focus rests on behavior. Rather than analyzing how things are, interaction design synthesizes and imagines things as they could be. This element of interaction design is what characterizes IxD as a design field, as opposed to a science or engineering field.
Central forceIn classical mechanics, a central force on an object is a force that is directed towards or away from a point called center of force. where is the force, F is a vector valued force function, F is a scalar valued force function, r is the position vector, ||r|| is its length, and is the corresponding unit vector. Not all central force fields are conservative or spherically symmetric. However, a central force is conservative if and only if it is spherically symmetric or rotationally invariant.
Interaction techniqueAn interaction technique, user interface technique or input technique is a combination of hardware and software elements that provides a way for computer users to accomplish a single task. For example, one can go back to the previously visited page on a Web browser by either clicking a button, pressing a key, performing a mouse gesture or uttering a speech command. It is a widely used term in human-computer interaction. In particular, the term "new interaction technique" is frequently used to introduce a novel user interface design idea.
