Vibrational Artificial Subtle Expressions: Conveying System’s Confidence Level to Users by Means of Smartphone Vibration

Artificial subtle expressions (ASEs) are machine-like expressions used to convey a system's confidence level to users intuitively. So far, auditory ASEs using beep sounds, visual ASEs using LEDs, and motion ASEs using robot movements have been implemented and shown to be effective. In this paper, we propose a novel ty…
