Summary / Description
| Summary / Description | A key constraint on the effectiveness of window-based human-computer interfaces is that the display screen is too small for many applications. This results in “window thrashing,” in which the user must expend considerable effort to keep desired windows visible. Rooms is a window manager that overcomes small screen size by exploiting the statistics of window access, dividing the user's workspace into a suite of virtual workspaces with transitions among them. Mechanisms are described for solving the problems of navigation and simultaneous access to separated information that arise from multiple workspaces. |

User interface with mulitple workspaces
An article of manufacture for use in a system that includes a display; a processor for controlling the display; and display object data the processor can use to generate first and second display objects the processor can present on the display; the article comprising:
memory that can be accessed by the processor; and
data stored in the memory; the data comprising:
first and second workspace data structures relating respectively to first and second workspaces that the processor can present on the display; each of the first and second workspaces including a respective set of display objects; each of the display objects being perceptible as a distinct, coherent set of display features; the display objects of each respective set being perceptible as having spatial positions relative to each other when the respective workspace is presented on the display; and
first and second linking data structures; the first linking data structure linking the first workspace data structure and the display object data so that the processor presents the first display object in the first workspace's set of display objects; the second linking data structure linking the second workspace data structure and the display object data so that the processor presents the second display object in the second workspace's set of display objects; the first and second display objects being perceptible as the same tool.
