Remote pointing devices like the Wii remote and Smart TV remote controllers have a wide range of applications and are becoming more important for the manipulation of and interactions with information on a distant display due to wide-screen display and wireless technology in electric home appliances as well as the most advanced computing technology of virtual environment and augmented reality. Because remote pointing devices are used without external support, however, muscular tremors and motional disparity between the display and motor space can result in usability problems of mouse jitters and instability. In the present study, we propose a solution using feedforward technology with multisensory stimulation in which a user is provided with predictive information while approaching a target. Using a psychophysical experiment for user behavioral effectiveness and a survey for subjective rating for user satisfaction and difficulty, the feedforward technique was found to be more effective than was typical feedback. Also, the modality variations in feedforward were discussed. In particular, the feedforward with auditory and tactile stimulation was effective in user experience. The findings can be used to improve user interfaces for remote pointing controllers.
