Emerging mobile interfaces are characterized by an increasing need for socially acceptable interaction supporting unobtrusive input. Simultaneously, they require rich visual feedback for many dynamic and complex mobile tasks. With this paper, we want to identify and discuss design options and parameters for body-centric and personal mobile interaction techniques that aim to be well-suited for both: social acceptability and rich functionality. Wearable E-Textiles are a promising research field for unobtrusive mobile computing since they allow novel, subtle and personal input controls. Therefore, we investigate, how they can be combined with high-quality Augmented Reality (AR) glasses to seamlessly
provide visually augmented controls. For this, we question the role of visual feedback for unobtrusive mobile interfaces by classifying and discussing task- and context-depending visual feedback along the dimensions of the feedback type, position, time and visibility. Based on the sweet spots that we identified in our design classification, we conclude with two augmented E-Textile prototypes for future discussions.
