Tool-based hairstyling metaphors

Despite decades of research, digital hairstyling is still a difficult, long and tedious task. One reason for the absence of efficient and simple, yet accurate hair modeling interfaces is the lack of appropriate interaction metaphors enabling efficient styling functionalities. This paper discusses tool-based interaction metaphors for digital hairstyling applications with a specific focus on haptic modeling methods. We define users tasks, ergonomic aspects, as well as haptics-based styling and fine-tuning tools, concluding with a validation of selected interactions on an experimental prototype.
