Beyond "couch potatoes": from consumers to designers
Publication Year: 1998, Page(s):2 - 9
Cited by: Papers (6)The fundamental challenge for human computer interaction (HCI) is to invent and design a culture in which humans can express themselves and engage in personally meaningful activities. Cultures are substantially defined by their media and tools for thinking, working, learning, and collaborating. New media change: (1) the structure and contents of our interests, (2) the nature of our cognitive and p... View full abstract»

Reduction of overhead in drawing figures with computer-detailed analyses of drawing tasks
Publication Year: 1998, Page(s):11 - 18In drawing figures using a computer assisted drawing editor, users often find it difficult to draw figures that seem to be very simple. To explain this problem, the paper first introduces an operation model that consists of two layers: concrete layer and abstract layer. The problem is that a user must deal with invisible abstract pictures, which is a combination of editor's drawing functions. To r... View full abstract»

Pattern languages for usability: an investigation of alternative approaches
Publication Year: 1998, Page(s):25 - 30
Cited by: Papers (8)The best way to ensure usability is to treat human factors as an input to design, rather than merely evaluating prototypes or design documentation. The capability of pattern languages to facilitate the design process, improve communication, and record design philosophies suggests that they may assist the user centred design process. Researchers have not yet investigated in detail what a pattern la... View full abstract»

Usability evaluation in the field: lessons from a case-study involving public information kiosks
Publication Year: 1998, Page(s):70 - 75Public information kiosks are used increasingly in Singapore to provide enquiries and services to the public. Thanks to the National IT2000 plan, such kiosks are now a common sight in public places. To ensure effective use of such kiosks, a field evaluation of a number of public information systems was conducted from a human factors perspective. The paper reports the results of the evaluation for ... View full abstract»

Perceived usability and system complexity
Publication Year: 1998, Page(s):76 - 81The study presented investigated the influence of system complexity and previous experience on the perception of usability. Each of 24 subjects used a standard (simple) and a feature-rich (complex) graphical information retrieval system to complete a total of 6 information searches. The subjects provided ratings of the ease of learning, using and understanding each system. These ratings were used ... View full abstract»

A comparison of four interaction modes for CAD systems
Publication Year: 1998, Page(s):82 - 87An evaluation experiment was conducted to compare four interaction modes: mouse based, pen based, pen+voice, and pen+voice+mouse modes. Subjects tested the four modes for drawing and modifying an engineering plan on a CAD system. The results show that the pen+voice+mouse mode was the best of the four modes, in terms of total manipulation time (drawing time and modification time), and the subjects'... View full abstract»

Supporting mutual understanding in collaborative design project
Publication Year: 1998, Page(s):132 - 137
Cited by: Papers (1)In collaborative design, participants usually have different backgrounds and standpoints. Due to these differences, it is hard for participants to mutually understand intentions, and they must make a lot of effort to reach a mutual agreement on the design. Thus, the efficiency of the design processes is decreased. We propose a framework to support participants in mutual understanding by grasping a... View full abstract»
