Does it par-tickle?: Investigating the relationship between mid-air haptics and visual representations of surface textures.

Mid-air haptic feedback technology produces tactile
sensations that are felt without the need for physical interactions.
However, mid-air haptic experiences need to be congruent with
visual cues to reflect user expectations. To overcome this, we
investigate how to visually present properties of objects, so that
what one feels is a more accurate prediction of what one sees.
Specifically, this paper investigates the relationship between 8
visual parameters of a point-cloud representation of a surface
(particle color, size, distribution, etc.) and 4 mid-air haptic spatial
modulation frequencies (20, 40, 60 and 80 Hz). Our results and
analysis reveal a statistical significance between low and highfrequency modulations and particle density, particle bumpiness
(depth) and particle arrangement (randomness)
