Embroidery is a creative manual activity practiced by many people for a living. Such a craft demands skill and knowledge, and as it is sometimes complicated and delicate, it can be difficult for beginners to learn. We propose a system, named the Needle User Interface, which enables sewers to record and share their needlework, and receive feedback. In particular, this system can detect the position and orientation of a needle being inserted into and removed from a textile. Moreover, this system can give visual, auditory, and haptic feedback to users in real time for directing their actions appropriately. In this paper, we describe the system design, the input system, and the feedback delivery mechanism.
