In this paper we present a study we conducted to assess physical and perceptual properties of a tactile display for a tactile notification system within the CIRMMT Live Electronics Framework (CLEF), a Max-based 1 modular environment for composition and performance of live electronic music. Our tactile display is composed of two rotating eccentric mass actuators driven by a PWM signal generated from an Arduino microcontroller. We conducted physical measurements using an accelerometer and two user-based studies in order to evaluate: intensity and spectral peak frequency as function of duty cycle, as well as perceptual vibrotactile absolute and differential threshold. Results, obtained through the use of a logit regression model, provide us with precise design guidelines. These guidelines will enable us to ensure robust perceptual discrimination between vibrotactile stimuli at different intensities. Among with other characterizations presented in this study, these guidelines will allow us to better design tactile cues for our notification system for live-electronics performance.
