The effect of cognitive and affective aspects on usability

摘要

Studies on customer’s needs, desires and preferences have becomehighly important in the product design and development process.One consideration in usability is the cognitive aspect, which is relatedto the accommodation and evaluation of human cognitive capabilities,limitations and tendencies. In addition to the cognitive aspect, a recentstudy has shown that the affective aspect has been considered in theevaluation of product usability. Thus, both cognitive and affectiveaspects are deemed to be important for product design and the developmentprocess. Inherently, both aspects deliver complete humanand product interaction and experience. However, studies that considerthe affective process as a complement to the cognitive processfor usability are relatively rare. To address this gap, this study discusseshow an integrative framework of the cognitive and affective aspectscan be applied to a product for usability assessment via empirical studieson e-commerce and e-learning platforms. The sample involved 230respondents, using purposive sampling. The result shows that bothcognitive and affective aspects have a significant effect, although withdifferent weights. The affective aspect has been shown to improveproduct usability and user’s acceptance.
