In a previous study on information composition for a single user, it was discov- ered that organizing rich bookmarks in a meaningful way expressed ideas [9]. Rich bookmarks understood relationships among collected ideas via reflection and inter- pretation, then expressed these relationships via manipulating the visual features of rich bookmarks, such as location, orientation, and size in an information composition. Positioning rich bookmarks enabled the curators to discover emergent relationships among the collected information.

In our study, the information composition contained rich bookmarks curated by both partners, making it the place where their ideas collided and evolved. We observed that participants used the composition to help them collaboratively store, organize, and sift through their design ideas. Participants re-arranged the shared rich bookmarks into meaningful groups. They compared their own curated rich bookmarks with those shared by their partners. Participants’ ideation processes were stimulated not only by their own, but also by their partners’ interactions. These processes promoted emergent idea [82].

4.3.6.1 Temporary Territories

Participants established temporary territories on the information composition early on. They used transient empty space as temporary storage. One common behavior from participants was that they established territories on the information composition in early stages of design. Participants often divided the composition into two halves. Each half contained mostly rich bookmarks shared by the participant sitting close to that side of the collaborative surface. However, this territoriality of the composition was in many cases only temporary. The division blurred after some time, as participants moved rich bookmarks around in the composition. However, we found that in a few cases, strong territoriality remained throughout a couple’s design process.

4.3.6.2 Transient Storage Space

A design process style that contributed to dynamic changes in the composition involved the transient space participants used to temporarily place rich bookmarks. We observed different patterns of creating such space. When there were too many rich bookmarks on the composition, participants moved rich bookmarks that were currently not in use to the edges and corners . As an extreme case, one participant cleared up half of the composition to make room for creating a layout, and put rich bookmarks that were not used in the other half of the composition. Sometimes, participants removed rich bookmarks to make room, since they knew that they could bring them back when needed from their mobile collections.

Another method to create temporary storage space for rich bookmarks was pan- ning the composition. By panning the composition, participants always kept their focal center in the middle of the collaborative surface. However, it had disadvantages, because participants could not see rich bookmarks outside the displayed space.

4.3.6.3 Experiment with Ideas Spatially

Participants arranged rich bookmarks in different spatial layouts in the informa- tion composition to present and experiment with ideas utilizing the spatial relation- ships of rich bookmarks. During the design process, we observed highly dynamic changes to the layout of the information compositions as well as the forming and dissolving groups of rich bookmarks. Groupings have been found to function as an important basis for the formation of emergent ideas in information-based ideation [82]. They frequently put different rich bookmarks together to see how they matched each other in color and style. Different ideas were tested, and unwanted rich book- marks were removed from the composition. Participants often changed layers of rich bookmarks to better visualize the results of combination of rich bookmarks.

Rich bookmarks in the compositions often contained strong spatial relationships. The layout of rich bookmarks in the compositions reflected the spatial layout of the room in most cases. The composition usually appeared in an overhead view or birds eye view. In these cases, participants referred the top part of the composition as the back of the room, and the bottom of the composition as close to themselves. For example, Figure 4.15 shows a layout of a bathroom.

Participants also used the layering of rich bookmarks to express and visualize ideas. The workspace of the information composition is a ‘flatland’ while a room that participants were designing was in three dimensional space [83]. Despite of this constraint, layering rich bookmarks helped participants to visualize the information and ideate in three dimensional space. For example, participants put rich bookmarks of pillows over a rich bookmark of a sofa to emulate what they would normally arrange these items at home. They resized rich bookmarks so the pillow had the appropriate size on the sofa.

In one session, the male participant shared the same rich bookmarks of a bath- room tile and a wooden floor multiple times to the composition, and arranged them as if he was paving the wall and the floor in his own bathroom at home 4.16 with tiles and wooden floor. All the other rich bookmarks were placed on these tile and floor clippings. He told his partner during the collaboration that doing this help him design.

In some sessions, even though the layout of an information composition did not directly map to the layout of a room, it still expressed participants’ ideas in a mean- ingful way. Some participants arranged rich bookmarks into category subgroups. Each subgroup contained rich bookmarks with similar or complementary functions

to other rich bookmarks in the same group. For example, in the composition shown in Figure 4.17, multiple rich bookmarks of the same category of appliances or furniture were grouped together for easy comparison.

In another session, participants told us that although they did not put much attention to the spatial arrangement of rich bookmarks in their composition, their curation product featured a vague line separating rich bookmarks into two groups: ideal and practical.
