Recent work has shown that the body provides an interesting interaction platform. We propose a novel sensing technique based on transdermal low-frequency ultrasound propagation. This technique enables pressure-aware continuous touch sensing as well as arm-grasping hand gestures on the human body. We describe the phenomena we leverage as well as the system that produces ultrasound signals on one part of the body and measures this signal on another. The measured signal varies according to the measurement location, forming distinctive propagation profiles which are useful to infer on-body touch locations and on-body gestures. We also report on a series of experimental studies with 20 participants that characterize the signal, and show robust touch and gesture classification along the forearm.

Body Area Network approaches leveraging intra-or near-body communication offer exciting opportunities to utilize the human body as a signal transmission channel. Improvements in technical feasibility have encouraged research proposing mobile applications using data transferring touch interaction. In this work, we aim to provide haptic feedback for these applications to improve user experience. We propose a wearable haptic feedback device that uses electrostatic force to provide physical stimuli when a user touches objects that are electrically grounded, or of opposite polarity. Unlike previous approach, we neither physically actuate objects nor use any hand-worn haptic feedback devices. We introduce a mechanism to artificially build up electrostatic charge within the human body, and further leverage the effects of electrostatic discharge to create novel physical stimuli. In this paper, we report the underlying theory of operation as well as details of our prototype implementation. We use our prototype to explore the design space of interactions based on body-channeled physical stimuli, we illustrate our results using two applications: a) SandStorm: visualization of actuated force field using sand, and b) CheckMate: future vision of a touch-based transaction checkout system that provides haptic sensation for more reassuring feedbacks.
