Core Concepts
iFace introduces a novel wearable solution for recognizing hand-over-face gestures using impedance sensing, offering privacy-friendly and unobtrusive interactions.
Abstract
The content introduces iFace, a wearable device for recognizing hand-over-face gestures.
It discusses the sensing principle, hardware design, system evaluation, and potential applications.
iFace uses impedance sensing on the shoulders to detect gestures without placing sensors on the face or hands.
A user study showed an average Macro F1 Score of 82.58% for recognizing six hand-over-face gestures.
Potential applications include enriching implicit interactions, augmenting non-visual communication, and understanding cognitive states.
Stats
"iFace reaches 82.58% macro F1 score."
Quotes
"Hand-over-face gestures can provide important implicit interactions during conversations."
"iFace does not require the placement of sensors on the user’s face or hands."
