We have developed a prototype hypermedia CAI system called HIMAT (HItachi MultimediA learning Tool). HIMAT is a hypermedia CAI system on UNIX-based workstation. It has two features for the improvement of the usability; metaphor interface which adopts the concept of the metaphor as a central user interface look and feel, and the ladder structure of the teaching materials which is planned to prevent the student from losing position in hyper structure space. With HIMAT, nine sample users studied and their behaviours were recorded. Later, the sample users were interviewed and questionnaires were collected from them. These recordings, result of interview, and questionnaires, proved the following considerations. 1) When users use link anchors, they tend to push link anchors when they find them for the first time. Therefore, if link anchors are embedded in the middle pages of the teaching materials, they often stray from the start point and then lost their current positions in hyper structure space. 2) The number of hyperlink on each page does not affect the users' behaviour of learning. Therefore the number of link anchors can be entrusted to the authors of teaching materials. 3) The length of teaching materials affect users' degree of comprehension considerably. Lengthy materials often reduce users' concentration and will to study. So the length should be restricted to proper length. These consideration should be reflected to the guidelines for designing hypermedia teaching materials.
