【 摘 要 】

In the field of Human-Computer Interaction, several projects aim to develop new technological aids, which enable and provide people who are blindthe ability to navigate themselves around on their own. In order to evaluatethese technological aids, the created cognitive maps which are built by the helpof technological aids should be evaluated at first. A new approach has been de- veloped for evaluating these reconstructed cognitive maps quantitatively. In thispaper, we describe how this approach has been developed. Nine criteria areidentified and weighted with help from the blind people. Using weightedEuclidean distance enables the cognitive maps to be compared with each other.
