From a Measured Pinch to a Virtual Illusion: SingleTact's Role in KAIST's CHI 2026 Haptics Study
KAIST's Graduate School of Culture Technology has developed finger tendon vibration (FTV), a technique that creates the illusion of finger movement in virtual reality, without any device physically moving the finger.
To make the illusion work, researchers Kun-Woo Song, Youngrae Kim, and Sang Ho Yoon needed precise, real-time knowledge of how hard participants were pinching.
Our SingleTact S15-4.5N sensor, built into a small handheld cube, measured that pinch force at 100Hz, giving the team the ground-truth data needed to trigger the vibration at exactly the right moment and force level.
Thank you to the KAIST team for putting SingleTact to work in such a creative application of tactile sensing.
