Human–computer interaction studies the design and use of computer technology, focused on the interfaces between people and computers. Retaining irrelevant criteria and omitting essential ones will mislead the direction of the usability evaluation. 10.5.5 Communication through the artifact............ 51, 36 7.3.4 Using previous studies in evaluation, Model-based evaluation................... 36 rating on a scale of 0-4 (see also pg 325). tational artifacts smoothly with the world of physical artifacts. sonal, people with autism can use them well as a communications medium.

This paper introduces the LBG ‘Se- crets of the South’, designed to orchestrate social interaction in public space, and foster communication, collaboration, IT literacy, and social/cultural skills through 1) interaction-based social encounters with both friends and unknown members of the community, and 2) in-situ learning about the history and social context of the neighbourhood.

Nothing interesting in this subsection ;). This module focuses on the possibilities and challenges of interaction beyond the desktop. The second step is fuzzy Delphi analysis, which includes the design and validates the fuzzy Delphi instrument and the utilisation of the fuzzy Delphi method to analyse the fuzziness consensus of experts' opinions on the usability evaluation criteria.
