Spiky Starfish: Exploring 'Felt Technology' Through a Shape Changing Wearable Bag

Abstract

In HCI there are attempts to create expressive computing by exploring emotional engagements through a wide range of shape-changing interfaces including experimental art, fashion, architecture, furniture, etc. These approaches range from hedonic design purposes, which represent novel ideas and materials to more informative design spaces, which allow users to interact with a visual interface in order to persuade users' behavior. By bridging these explorations, I present Spiky Starfish, a computational wearable bag, which utilizes "felt experience with technology" to influence user bodily interaction tactically and visually. It is designed to explore how expressive shape-changing interface create a disruptive interaction when peoples' habitual behavior triggers.
