Expressivity
is a visceral capacity of the human body. To understand what makes a gesture
expressive, we need to consider not only its spatial placement and orientation
but also its dynamics and the mechanisms enacting them. We start by defining
gesture and gesture expressivity, and then we present fundamental aspects of
muscle activity and ways to capture information through electromyography and
mechanomyography. We present pilot studies that inspect the ability of users to
control spatial and temporal variations of 2D shapes and that use muscle
sensing to assess expressive information in gesture execution beyond space and time.
This leads us to the design of a study that explores the notion of gesture
power in terms of control and sensing. Results give insights to interaction
designers to go beyond simplistic gestural interaction, towards the design of
interactions that draw on nuances of expressive gesture.
