ABSTRACT
In this paper, we show a haptic feedback method named "Paired Vibratory Stimulation." We use two vibrators, one is attached onto the device and the other one is attached onto the fingernail. When the two vibrators are activated with different but close frequency, the beat vibration occurs only when the finger touches the device. A human can feel the beat vibration even when each original vibration is hard to be perceived. Therefore, the system can give vibratory sensation only at the contact area by using two vibrators. This is suitable for haptic feedback for a handheld mobile device. For the handheld device, sensation only arises at the contact area not at the holding hand or at the fingernail. This is also applicable to human skin interface system. Recently some researchers have proposed the systems which take advantage of human skin surface as an input media. Our method is suitable to give vibratory haptic feedback for that situation. We show our experimental results which clarified that the Paired Vibratory Stimulation can be achieved and applied to the human skin interface system.

Haptic Fidelity Framework: Defining the Factors of Realistic Haptic Feedback for Virtual Reality
CHI '22: Proceedings of the 2022 CHI Conference on Human Factors in Computing SystemsProviding haptic feedback in virtual reality to make the experience more realistic has become a strong focus of research in recent years. The resulting haptic feedback systems differ greatly in their technologies, feedback possibilities, and overall ...
Creating Haptic Illusion of Compliance for Tangential Force Input using Vibrotactile Actuator
UIST '17 Adjunct: Adjunct Proceedings of the 30th Annual ACM Symposium on User Interface Software and TechnologyWe demonstrate a haptic feedback method that generates a compliance illusion on a rigid surface with a tangential force sensor and a vibrotactile actuator. The method assumes a conceptual model where a virtual object is placed on a textured surface and ...
