Further, the multimedia learning layer of the model has to be revisited and extended. In fact, the focus of the future research will be on studying the usefulness of haptic technology in multimedia learning environments. The use of haptic technology can simulate cutaneous and kinesthetic sensations so that learning materials not only look but also feel (McGee, 2002) and may provide a means to reduce external cognitive load in visually and auditorily demanding learning materials (M�nch & Dillmann, 1997). Thus, I want to propose that in the future we should consider supplementing the multimedia learning layer with the haptic channel in order to be able to design more effective, engaging, and realistic learning materials
