A recent extension of this development is to also pay attention to the question how technology affects the subjective wellbeing or(More)
To determine the roles that the sensory modalities play in user product interactions, one modality was blocked during the execution of eight simple tasks. Participants reported how they experienced the products and how they felt during the experiment. Blocking vision resulted in the largest loss of functional information, increased task difficulty and task(More)
