Live Skin is a project that explores how to keep balance with technology. While we are more dependent on digital devices and spend increasing time on them，whether it’s for work, communication or entertainment， how do we balance the virtual and the physical world? Inspired by human nature skin，practice-based research was conducted to explore the possibility of “new skin” - a shape-changing interface that communicates information through its movement and tension. This is intended to helps people notice and reflect on the time they spend on digital devices and the data they encounter. Different from the existing solutions，this is an attempt to look away from digital devices that brought the problem, focus on the physical world and human body extension instead. The texture and the materiality of the new skin give users a new sense of the digital data, promoting reflection and motivation to keep balance with digital devices.
