Front Hair Styling Robot System Using Path Planning for Root-Centric Strand Adjustment

Soonhyo Kim, Naoaki Kanazawa, Shun Hasegawa, Kento Kawaharazuka, Kei Okada

TL;DR

This research presents a novel robotic system designed to automatically adjust front hairstyles, with an emphasis on path planning for root-centric strand adjustment, showing promising results for automated, precise hairstyle adjustments.

Abstract

Hair styling is a crucial aspect of personal grooming, significantly influenced by the appearance of front hair. While brushing is commonly used both to detangle hair and for styling purposes, existing research primarily focuses on robotic systems for detangling hair, with limited exploration into robotic hair styling. This research presents a novel robotic system designed to automatically adjust front hairstyles, with an emphasis on path planning for root-centric strand adjustment. The system utilizes images to compare the current hair state with the desired target state through an orientation map of hair strands. By concentrating on the differences in hair orientation and specifically targeting adjustments at the root of each strand, the system performs detailed styling tasks. The path planning approach ensures effective alignment of the hairstyle with the target, and a closed-loop mechanism refines these adjustments to accurately evolve the hairstyle towards the desired outcome. Experimental results demonstrate that the proposed system achieves a high degree of similarity and consistency in front hair styling, showing promising results for automated, precise hairstyle adjustments.

  • Figure 2: System overview for front hair styling robot system
  • Figure 3: Orientation difference over iterations for our proposed system and the random sampling method.
  • Figure 4: Box plot comparison of orientation differences between our proposed system and the random sampling method.
  • Figure 5: Final hair styling results. The image shows, from left to right: (a) the initial natural hair state before styling, (b) comparison between the initial state and a natural hairstyle, (c) comparison between the initial state and a 5:5 parting hairstyle, (d) comparison between the initial state and a 7:3 parting hairstyle, (e) the final result produced by our system, (f) comparison between the final result and a natural hairstyle, (g) comparison between the final result and a 5:5 parting hairstyle, and (h) comparison between the final result and a 7:3 parting hairstyle. Numerical values, indicated in red text, represent orientation differences, where smaller values indicate higher similarity to the target style. Notably, (b) has the smallest difference value, representing the closest similarity to the natural style, and (g) has the smallest difference value among the styled results, confirming the system's success in achieving the target 5:5 parting hairstyle.
