Effective training lives from a large degree of variation according to physiological research principles of deliberate practice. In this paper, we introduce a novel way of training by adding kinetic noise (randomized haptic vibrations) to the training process. Over the vibrations, we make the training process more difficult and hope to add variation (an important aspect of skill training in the psychology literature). We present an initial study (n=8) of dart-throwing training as a system test. Four users train with a sleeve (random vibro-tactile and thermal actuation) and 4 users are the control group (no sleeve). Both groups improve significantly over the training period (p <.05). Yet,the effect size is too low to make any claims regarding effectiveness between the groups. Still we believe our approach could be promising, we will explore in future work how to enhance skill acquisition training over randomized haptic actuation.
