A Factorial Design Experiment in Affective Combination of Visual and Tactile Stimuli in the Context of Keypads

One of the possible criticisms of affective engineering is that it is often used in a reductionist way. Different elements of a product design are tested separately and it is assumed that recombining the elements will produce a congruent whole. This paper reports an investigation into a method to test this assumption and, more specifically, determine the way in which people combine the effects of visual and tactile stimuli.
