  • Blueprint for the Decade
    Blueprint for the Decade In the 1990s, Apple will expand its role in both personal computing and enterprise computing. This will be driven by a focused product strategy that provides: • Rapid advances in our System 7 software architecture • Breakthroughs in how people interact with computers, fostered by the power of RISC • Enterprisewide client/server integration and A/UX-based open Macintosh computers and servers • An object-oriented operating system that will revolutionize the economics of software development for enterprise computing, code-named “Pink.” Our goal is to help people, individually and in organizations, transform the way they work, learn, and communicate by offering exceptional computing products and customer services. Apple will continue to be known as the company that leads the industry by providing powerful, innovative technologies that are easy to use. Our product strategy begins, as always, with Macintosh. The new products will complement and coexist with our current products, sharing data, networks, printers, file servers, and application software. A smooth migration path is a fundamental part of each new product development effort. We think that these new products will be important to the entire industry. Apple believes that its role is to develop rich platforms upon which powerful and easy-to-use applications software can be created by other companies. As the computer industry increasingly requires complex interdependencies for the development of new industry standards, Apple will no longer go the distance alone. Whenever technologies can best be developed and marketed through partnerships, alliances, and licensing arrangements, we will do so. We expect to work closely with other major industry players.

    Reinventing User Applications for Mission Control Jay Trimble NASA Ames Research Center, Mountain View CA, 94035, USA Alan Crocker NASA Johnson Space Center, Houston TX, 77062, USA I. Introduction Scenario, Present Day – In a simulation de-brief, flight controllers discover the need to build a multi-discipline composite display. They submit a software change request to platform services. Constrained by a traditional software change process, the changes roll out and are available for use months later. Scenario 2011 – In a simulation, flight controllers discover the need to build a multi-discipline composite display. After the de-brief is over, one flight controller stays an extra hour. Using Mission Control Technologies (MCT) certified composable user objects, the controller builds the new displays. Within the hour, the display is ready for use. Exploration Scenario – A future mission control center has continued what the International Space Station Flight Controllers have begun—the combining of what were previously multiple flight control positions into one. A slimmed down mission control center is guiding a descent to the lunar surface. Using an MCT multi-disciplinary display composition, a flight controller executes a procedure. Within each procedure step, commands and telemetry are composed, so no context switching between software packages is required. On a nearby console, another operator is viewing some of the same information. She has composed only the telemetry points she needs, and she’s viewing them as plots, not alphanumerics, as in the procedure steps. These scenarios illustrate the capability of technology now being installed and tested in NASA Johnson Space Centers (JSC) Mission Control Center (MCC).

  • Graphic User Interface
    УДК 004.4 V. V. Mahlona GRAPHIC USER INTERFACE Vinnytsia National Technical University Анотація В даній роботі було досліджено значимість графічного інтерфейсу історію виникнення графічних інтерфейсів та їх перші застосування, проведено порівняння з іншими інтерфейсами. Ключові слова: графічний інтерфейс користувача, дослідження, інтерфейс, ОС, Windows, Linux, MacOS Abstract The article deals with the importance of a graphical user interface, the history of graphic interfaces and their first applications are presented, the comparison with other interfaces is given. Keywords: GUI, research, interface, OS, Windows, Linux, MacOS The graphical user interface (GUI) is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, instead of text- based user interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls. The term GUI tends not to be applied to other lower-display resolution types of interfaces, such as video games (where head- up display (HUD) is preferred), or not including flat screens, like volumetric displays because the term is restricted to the scope of two-dimensional display screens able to describe generic information, in the tradition of the computer science research at the Xerox Palo Alto Research Center.
