This thesis concerns the relationship between aspects of cognitive differences and interface design in the context of visual impairment. Among a number of sources of cognitive differences studied, this work focuses on Witkin’s Cognitive Style Theory (1971). According to this theory people are more or less field-dependent. A field-independent person has good analytical and restructuring skills while the field-dependent individual has a more holistic approach and good inter-personal skills. According to several researchers, a number of design aspects such as dialogue style, user versus system guiding etc., can be designed to accommodate these differences in cognitive style. An interview study gives some support to the hypothesis that this relationship between cognitive style and design aspects also is relevant in a context of visual impairment.
