....when any of those conditions was enabled. This very simple example illustrates the use of separate continuous and discrete specifications and the way in which the enabling and disabling of the continuous relationships by the state diagram provides the connection between the two. Abowd[1] and Carr[4, 5] also present specifications of sliders which separate their continuous and discrete aspects in different ways (see Section 7) and the Kaleidoscope constraint language[15] can support temporary constraints roughly similar to the one in this example. Figure 2 shows an alternative form of the ....

.... Card, and Robertson address the description of interfaces by continuous models by discussing interface syntax as a set of connections between the ranges and domains of input devices and intermediate devices[40] While their focus is on widgets found in current WIMP interfaces, Abowd[1] and Carr[4, 5] both present specification languages that separate the discrete and continuous spheres along the same lines as this model. Both approaches support the separation of interaction into continuous and discrete as a natural and desirable model for specifying modern interactive interfaces. Carr ....

....either support this level, or can easily be extended to support this level, treatment is fairly cursory. UAN provides a reasonably complete, concise, and intuitive notation for graphical interaction. This has been incorporated into a statechart based language in Interaction Object Graphs (IOG) [3]. Finally, the physical level deals with the devices which the users interact with, and the information directly presented to the users. The languages described in this paper tend to focus on higher level dialogue. Detailed visual descriptions of an interface are often separated from ....

....descriptions. Approaches 1, 2, and 3 can cause a measure of separation of the components of each requirement (state, events, and rules) and may need to be detailed in different parts of the specification. Approach 4 (based around ideas from Statecharts [3] and also adopted for user interfaces [1]) is the better solution for our objectives, being more concise and keeping components localised. Nevertheless, in all four approaches, requirements remain coupled to the rest of the specification structure and need to be understood within this context when constructing and reading it. In ....

....by dropping a new attribute name over the original widget s attribute name. Existing widgets can be deleted by dropping No Query onto the corresponding attribute name. Kumar, Plaisant, Shneiderman 7 The Treeview and Range slider widgets of the University of Maryland Widget Library TM (Carr, Jog, Kumar, Teittinen, Ahlberg, 1994) were used in the PDQ Tree browser implementation. If users manipulate a widget at the current lowest level displayed, the nodes matching the query at that level are colored yellow, otherwise they are gray. These updates of the data display are realtime (within 100 msec of updates to the control ....
