Leaping to document landmarks such as next or previous word, line, page, section, and document amounts to leaping to Space, New line, Page, and Document characters, which are inserted using the Spacebar, Enter, Page and Document keys respectively. This process is intended to habituate the user and turn cursor positioning into a reflex. Leaping is performed as a quasimode operation: press the Leap key and, while holding it, type the text that you want to search finally release the Leap key. The system provides two commands, Leap-forward and Leap-backward, invoked through dedicated keys (meant to be pressed with the thumbs), that move the cursor to the next and prior position that contains the search string. Leaping Leaping in the Archy interface.Ī main feature of the interface is Leaping, a means of moving on-screen via incremental text-search. Universal and unlimited undo is one key element for the design goals stated in The Humane Interface, since it allows for all the user's work to be recovered in any case. The system state is preserved and safe from crashes and power outages: if the system crashes or power goes off, one simply restarts the system and takes up working where one left off when the problem occurred.Ī detailed history of the user's interaction allows all actions to be undone since his/her very first action performed within Archy, and re-done again up to the most recent action. This eliminates the need for, and the concept of, saving a document after editing it. In order to achieve this, modal features of current graphical user interfaces, like windows and separate software applications, are removed.Īll content in Archy is persistent. The plan includes making the interface as "modeless" as possible, to avoid mode errors and encourage habituation. This ambitious plan to build a general purpose environment that is easy to use for anyone is based on designing for the common cognitive capabilities of all humans. It aims to be usable by disabled persons, the technology-averse, as well as computer specialists. The stated goal of Archy is to design a software system starting from an understanding of human cognition and the needs of the user, rather than from a software, hardware, or marketing viewpoint. Jef Raskin jokingly stated: "Yes, we named our software after a bug" (a cockroach), further playing with the meaning of bugs in software. It is also an allusion to Don Marquis' archy and mehitabel poetry. The name "Archy" is a play on the Center's acronym, R-CHI. On January 1, 2005, Raskin announced the new name, and that Archy would be further developed by the non-profit Raskin Center for Humane Interfaces. While these systems build upon the WIMP desktop paradigm, Archy has been compared as similar to the Emacs text editor, although its design begins from a clean slate.Īrchy used to be called The Humane Environment ("THE"). Archy is more radically different from established systems than are Sun Microsystems' Project Looking Glass and Microsoft Research's "Task Gallery" prototype. It can be described as a combination of Canon Cat's text processing functions with a modern ZUI. Since his death in February 2005 the project was continued by his team, which later shifted focus to the Ubiquity extension for the Firefox browser.Īrchy in large part builds on Raskin's earlier work with the Apple Macintosh, Canon Cat, SwyftWare, and Ken Perlin's Pad ZUI system. The system was being implemented at the Raskin Center for Humane Interfaces under Raskin's leadership. These ideas include content persistence, modelessness, a nucleus with commands instead of applications, navigation using incremental text search, and a zooming user interface (ZUI). Designed by human-computer interface expert Jef Raskin, it embodies his ideas and established results about human-centered design described in his book The Humane Interface.
