....collections, it is impossible to display labels for every item simultaneously, especially as the labels are larger than the points, which is why many systems require the user to click on an item or hover over it with the mouse pointer in order to see its label. For example, Chen and Czerwinski [23] created a VRML visualisation of 169 abstracts of academic papers, where each point was permanently labelled only with the initials of the corresponding paper s author; running the mouse over a point displayed the paper s title, and clicking on it opened the abstract in a frame next to the ....

....was difficult to identify the source of these individual differences, beyond the advice of another conference attendee, that you can t expect designers to agree on anything. We wanted to consider individual differences in more depth in this experiment. A number of previous studies (such as [23, 116]) have found that participants spatial ability can be correlated with their performance in tasks involving navigation through a user interface. We were interested to know if differences in spatial ability would affect people s usage of similarity based visualisations of image sets, and therefore ....

....by the creators of the stock photograph library. The instructions were also carefully worded, to try to ensure that both arrangements were presented as being equally valid. We wanted to consider individual differences in more depth in this experiment. Other information visualisation researchers [6,18] have found that the results from tests of spatial ability can be correlated with quantitative experiment results. We therefore asked our participants to take Set I (12 questions) of Raven s Advanced Progressive Matrices (APM) 12] a culture free test of spatial reasoning that specifically ....

....favorite visual interface may be another user s nightmare. Individuals have relatively stable cognitive preferences and abilities that can be measured by psychometric tests. For example, spatial ability indicates an individual s ability to recognize and handle spatial relationships of objects [8, 9]. Research in human computer interaction has shown that individual differences can be the most significant factor in one s perform ance. 6. Supporting Collaborative Work Given the individual differences we need to accommodate and the diversity of social norms in cyberspace, supporting ....

....challenging. A number of empirical studies in hypertext systems focused on spatial ability and cognitive style [2] The interrelationship between individual users spatial ability and the spatial semantic user interface generated with similar techniques was explored in a recent empirical study [5]. Empirical studies also suggested that a good structural visualisation may be particularly useful to people with lower visualisation ability. Campagnoni and Ehrlich [2] found that users with lower visualisation ability used the top level table of contents more frequently than users with good ....

....coordinates along the third dimension are restrained within specified regions during the node placement process. There is notable lack of empirical studies in related areas, such as the study of effects of spatial ability of individual users on visual navigation (but see Chen and Czerwinski [8]) In fact, we found that it might be sensible if we simply reserve the third dimension for incorporating additional navigational information subsequently. In later sections, we will show an integrated environment in which users would have a wider range of options. They would be able to utilise ....

....the most important aspects of human factors in association with spatial representations. A number of empirical studies in hypertext systems focused on spatial ability and cognitive style, in particular, interaction between cognitive styles and structural maps in hypertext [29] and a spatial world [8]. Previous studies in hypertext suggested that spatial ability is a significant factor that affects users satisfaction and performance with hypertext systems (see Chen and Rada [28] for a meta analytical summary) Users with high spatial ability completed tasks more quickly than users with lower ....

....category labels, as well as having the ability to visualize related clusters of information in an intuitive manner. Few to no novel browsers have sufficiently managed this rather ambitious task to date, although our group at Microsoft, as well as many others, is working hard on this problem [1, 3, 10]. Background Knowledge Requirements It should be obvious from the positive and negative features listed earlier here that the future designs of Web browsers will be complex. The HCI professional will necessarily need to understand a variety of phenomena related to visual, auditory, and perhaps ....

....is in a range between medium and large. The meta analysis also found that graphical maps reduced the differences in dependent measures (Z = 3. 37, p = 03, one tailed) The relationship between spatial ability and visual navigation in a virtual reality based spatial user interface was studied in (Chen Czerwinski, 1997). Spatial ability (VZ 2) was strongly correlated with the accuracy of sketches made by subjects after they searched through a spatial semantic model, which was very similar to the one used in the studies in this paper. The spatial ability was positively correlated with the differences between the ....

....were given two search topics. They were told to find as many relevant papers as they could for the first topic within 15 minutes. For the second topic, they were told to stop once they found five relevant papers. Following the design of our earlier study of spatial ability and visual navigation (Chen Czerwinski, 1997), subjects were asked to sketch the spatial layout of the search space at the end of the first search session. When subjects completed the second topic, they were asked to name the cluster of papers in the semantic space. This was designed to find out what subjects could remember after having ....

....suggested that spatial ability may be a significant factor affecting users satisfaction and performance with spatial hypertext systems. We have recently conducted an empirical study to investigate the interaction between users spatial ability and their search patterns with the spatial hypertext [4]. Here we will summarise some interesting findings of our empirical study as the focus of this paper is on design principles and how these principles can be transformed into spatial hypertext with a set of combined theories and techniques.

Readers are referred to [4] for a more detailed report of the empirical study. Subjects were postgraduate students enrolled in an M.Sc. in Information Systems. They were not familiar with the underlying theories and algorithms used in the design. Subjects were asked to find papers related to particular topics within a ....
