To design an easy-to-use interface, pay attention to what users do, not what they say. Self-reported claims are unreliable, as are user speculations about future behavior.

Edwards, W. Keith, Hudson, Scott E., Marinacci, Joshua, Rodenstein, Roy, Rodriguez, Thomas K. and Smith, Ian (1997): Systematic Output Modification in a 2D User Interface Toolkit. In: Robertson, George G. and Schmandt, Chris (eds.) Proceedings of the 10th annual ACM symposium on User interface software and technology October 14 - 17, 1997, Banff, Alberta, Canada. pp. 151-158.

In this paper we present a simple but general set of techniques for modifying output in a 2D user interface toolkit. We use a combination of simple subclassing, wrapping, and collusion between parent and output objects to produce arbitrary sets of composable output transformations. The techniques described here allow rich output effects to be added to most, if not all, existing interactors in an application, without the knowledge of the interactors themselves. This paper explains how the approach works, discusses a number of example effects that have been built, and describes how the techniques presented here could be extended to work with other toolkits. We address issues of input by examining a number of extensions to the toolkit input subsystem to accommodate transformed graphical output. Our approach uses a set of "hooks" to undo output transformations when input is to be dispatched.

Isaacs, Ellen, Morris, Trevor, Rodriguez, Thomas K. and Tang, John C. (1995): Comparison of Face-To-Face and Distributed Presentations. In: Katz, Irvin R., Mack, Robert L., Marks, Linn, Rosson, Mary Beth and Nielsen, Jakob (eds.) Proceedings of the ACM CHI 95 Human Factors in Computing Systems Conference May 7-11, 1995, Denver, Colorado. pp. 354-361.

As organizations become distributed across multiple sites, they are looking to technology to help support enterprise-wide communication and training to distant locations. We developed an application called Forum that broadcasts live video, audio, and slides from a speaker to distributed audiences at their computer desktops. We studied how distributed presentations over Forum differed from talks given in face-to-face settings. We found that Forum attracted larger audiences, but the quality of interaction was perceived to be lower. Forum appeared to provide more flexible and effective use of slides and other visual materials. On the whole, audiences preferred to watch talks over Forum but speakers preferred to give talks in a local setting. The study raises issues about how to design this technology and how to help people discover effective ways of using it.

Isaacs, Ellen, Morris, Trevor and Rodriguez, Thomas K. (1994): A Forum for Supporting Interactive Presentations to Distributed Audiences. In: Proceedings of the 1994 ACM conference on Computer supported cooperative work October 22 - 26, 1994, Chapel Hill, North Carolina, United States. pp. 405-416.

Computer technology is available to build video-based tools for supporting presentations to distributed audiences, but it is unclear how such an environment affects participants' ability to interact and to learn. We built and tested a tool called Forum that broadcasts live audio, video and slides from a speaker, and enables audiences to interact with the speaker and other audience members in a variety of ways. The challenge was to enable effective interactions while overcoming obstacles introduced by the distributed nature of the environment, the large size of the group, and the asymmetric roles of the participants. Forum was most successful in enabling effective presentations in cases when the topic sparked a great deal of audience participation or when the purpose of the talk was mostly informational and did not require a great deal of interaction. We are exploring ways to enhance Forum to expand the effectiveness of this technology.
