Kids' Space

摘要

In this study we evaluated virtual environments for children. We compared two virtual web applications: 4kidz and KinderCampus. The aim of the study was to evaluate children's acceptance of the system and the usability of the virtual environment. Usability was measured with a scenario based testing of the website. The kids should fulfil a variety of tasks. While exploring the web site the attention of the kids was measured by counting the eye-fixation time and rate on the screen. Concerning usability KinderCampus which could be characterized as a very intuitive virtual environment showed the best results. The navigation of the system is based on a space metaphor. Even illiterate children at the age of four were able to use the system and showed great pleasure while exploring the virtual environment. 4kidz caused many usability problems. Contrary to the other systems the navigation concept was not based on a metaphor concept. Especially the younger kids where not able to use the system and therefore, got frustrated. Results highlight the need for navigation concepts that follow a consistent spatial metaphor. Results also showed that the system has to give a very fast and clear feedback, otherwise kids loose.track very easily.
