“…In collaborative tabletop groupware systems there is a tension between orienting textual data towards the user to facilitate readability, and orientation of interface objects to facilitate interaction, cognition, and communication as observed by Tang (1991) and Kruger et al (2003). Our experimental results agree with those seen previously that orientation has an effect on speed of reading, and that if maximum reading speed is desired and the position of the intended reader is known, text should be oriented directly towards that user.…”

“…An examination of the role of artifact orientation in collaborative settings has been presented by Tang (1991) and Kruger et al (2003). The lessons they present are clear: orientation has a role to play in collaboration, and any simple, one-sized-fits-all algorithmic solution to the issue of orientation of screen artifacts will deprive participants of some of the richness of interaction afforded in paper-based tasks.…”

“…It was our hypothesis that, given this environment, the effect of orientation on task-performance would be less dramatic. If this were the case, we believe that the tension between orientation as a tool for collaboration and the apparent need to use the "right" orientation for text readability can be relaxed, and systems could begin to be designed that heed the observations of Tang (1991) and Kruger et al (2003).…”

“…Research has been conducted into how participants in non-computer based, tablecentered collaborative tasks make use of orientation (Tang 1991;Kruger et al 2003). These investigations have shown that users prefer a straight-on orientation for reading text, and orient objects towards themselves, others, or in-line with shared artifacts to ease reading in different circumstances.…”

Empirical Investigation into the Effect of Orientation on Text Readability in Tabletop Displays

Tabletop collaborative groupware is a newly re-emerging field in CSCW. The use of a tabletop display presents a unique challenge to interface designers: how to optimally orient displayed objects for viewing and manipulation by users situated at various locations around the table. A great deal of CSCW research has been conducted under the implicit assumption that textual elements should be oriented directly toward the reader, despite research that demonstrates that a simple, straight-on orientation is not necessarily ideal in all circumstances. Absent from this ongoing research dialogue, however, has been an empirical examination of user performance of reading text on tabletop displays at non-zero orientations. In this paper, we present two studies which examine the effect of text orientation on common tasks: the reading of a small piece of text, and the serial search for a label. We found that, though statistically significant, the effects of orientation on the performance of these tasks were less dramatic than might have previously been assumed. From this, we hope to help guide collaborative groupware designers as to when orientation should be "corrected".

“…In 1989, I and my students decided to build a simple drawing application for distributed participants designed around John Tang's human factors observations of how small design teams draw together [17]. The result was GroupSketch [11], a program written over several months by student Ralph Bohnet.…”

Groupware: Design, Implementation, and Use

Abstract. Effective groupware toolkits not only make it possible for average programmers to develop groupware, but also enhance their creativity. By removing low-level implementation burdens and supplying appropriate building blocks, toolkits give people a 'language' to think about groupware, which in turn allows them to concentrate on creative designs. This is important, for it means that programmers can rapidly generate and test new ideas, replicate and refine ideas presented by others, and create demonstrations for others to try. To illustrate the link between groupware toolkits and creativity, I describe example toolkits we have built and how others have leveraged them in their own work.
