“ It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them. ”

Vaananen, Kaisa and Henderson, Dave (1993): Testing Acceptance and Usability of Multimedia in Man-Machine Communication: A Case Study and Guidelines. In: Proceedings of the Fifth International Conference on Human-Computer Interaction 1993. pp. 450-455.

“This paper describes the evolution and application of a method of usability testing. The case study evaluates the human-computer interface of a multimedia information system. The method of evaluation can be integrated into the design process of similar highly interactive systems. The objective of the work described in this paper is to improve the chances of success of any multimedia system in casual and long term use. This is done by offering two types of guidelines: 1) For usability testing of interfaces to multimedia systems, and 2) for the design of these interfaces. These guidelines are targeted at the designers and developers themselves, i.e. no expert-level knowledge of human-computer interaction is assumed. ShareME, the multimedia information system, was tested for its usability among 39 target users. During the case study it was discovered that seemingly small changes to the interface can turn a partly frustrating system into a pleasant and engaging one.”

Vaananen, Kaisa and Hubner, Wolfgang (1992): ShareME -- Shared Multimedia Environments: Some Issues on Interaction in Distributed Multimedia Information Environments. In: Monk, Andrew, Diaper, Dan and Harrison, Michael D. (eds.) Proceedings of the Seventh Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers VII August 15-18, 1992, University of York, UK. pp. 369-388.

“This paper describes the conceptualization and realization of a system called ShareME for information acquisition and distributed student-expert collaboration. ShareME is a tool for building distributed multimedia information environments based on a network of NeXT workstations. The central concepts are structuring mechanisms for multimedia information space, user-oriented interaction and collaboration methods for heterogeneous media (audio, video, telecommunication, shared screens), and explicit user interface metaphors for multimedia environments. ShareME tool and the first test environment for information acquisition on the new German states are described. Using the ShareME tool and following the concepts presented allows the environment author to easily construct shared multimedia environments. In these environments the users can interact, communicate, collaborate, and acquire information in an intuitive and rewarding manner.”
