Finding a More Pleasant Compliance Illusion Method for a Hand-Held Device

Blog Article

A compliance illusion can be created if vibration bursts, called friction grains, are provided in response to changes in pressing force on a surface.This method has been used in many human-computer interaction applications.For instance, it can enrich virtual controls on a hand-held device with compliant feeling.However, one of the limitations of this method is that the friction grains that it uses feel “bumpy” and “buzzing,” which may pose a hurdle to the adoption of the method by consumer products where the affective quality essie win me over of tactile feedback is important.

To overcome 15-fd0038ca this limitation, we examined an alternative compliance illusion method, which computes the time derivative of the force applied by the user, and uses it to modulate a base vibration signal.We conducted a magnitude estimation experiment and showed that the alternative method with a sinusoidal base vibration signal can create significantly less bumpy, less buzzing, and thereby less unpleasant tactile feedback compared with the grain-based method while achieving the same level of compliance illusion effect as the grain-based method.
