Instructional information in adaptive spatial hypertext

Spatial hypertext is an effective medium for the delivery of help and instructional information on the Web. Spatial hypertext’s intrinsic features allow documents to visually reflect the inherent structure of the information space and represent implicit relationships between information objects. This work presents a study of the effectiveness of spatial hypertext as medium for delivery of instructional information. Results were gathered based on direct observation of the people reading a spatial hypertext document which was used as informational support for a complex task. Two versions of the spatial hypertext document were used: a non-adaptive and an adaptive.
