It is well known that unaware exposure to a visual stimulus increases the preferability of the associated object. In this study we examine whether the same phenomena occur for haptic stimuli. Using a touch-enabled virtual environment, we tested whether people that touch two virtual surfaces, which differ by imperceptible differences in roughness or(More)
Unaware haptic perception is often inferred but rarely demonstrated empirically. In this paper we present evidence for effects of unaware haptic stimuli on users' motor interaction with virtual objects. Using a 3D hapto-visual virtual reality, we ran a texture-difference-recognition test in which subjects glided a pen-like stylus along a virtual surface(More)
