This quantity comprises chosen papers provided on the 17th Colloquiumon bushes in Algebra and Programming (CAAP) held together with the eu Symposium on Programming (ESOP) in Rennes, France, February 26-28, 1992 (the lawsuits of ESOP look in LNCS 582). the former colloquia have been held in France, Italy, Germany, Spain, Denmark and England. each even yr, as in 1992, CAAP is held together with ESOP; another yr, it truly is a part of TAPSOFT (Theory And perform of software program development). first and foremost, CAAP used to be dedicated to algebraic and combinatorial homes of timber and their position in numerous fields of laptop technology. The scope of CAAP has now been prolonged to different discrete constructions, like graphs, equations and differences of graphs, and their hyperlinks with logical theories. The programme committee got forty submissions, from which 19 papers were chosen for inclusion inthis volume.

Example text

There it is shown how the annotations and events can be visualized to help observers get an overview of the usability test results. Annotations are transformed into timelines which are separated by annotation category into 4 levels. This approach for presenting time dependent information is natural and easily understandable and we will use a similar one in our work. On the other hand there are also some drawbacks. The first is that there is probably no systematic task representation so it is more complicated to separate each task.

When more participants are visualized, each one is represented by his own timeline. Each annotation is represented by a rectangle inside the task line. The width of annotation represents duration of annotation action. Annotations can be divided into several categories. Each category is represented by a different color. It is up to the observer as to which categories he creates and which color will be assigned to each category. Using the color as the main information carrier is encouraged in [18].

One way is to view the behavior of each group of participants separately. A second way is to view results from both groups of participants together but the task sequence for each participant will be different and task numbers in timelines will not be sequential. Nevertheless the correspondence of timeline segments and tasks in the task model is preserved by highlights. 34 I. Malý and P. Slavík Visualizing dynamics of a test Dynamics of the data can be inspected in detail, either inside one participant log or through several participants.
