机器人教练比手表更能让跑步者坚持、跑得更稳，还更有趣。
Will People Enjoy a Robot Trainer? A Case Study with Snoopie the Pacerbot
- 用四足机器人设计可自主跑动的训练伙伴，按用户能力定制间歇跑计划。
- 相比手表，用户跑得更准：节奏遵守率高60.6%，速度波动减少45.9%。
- 用户普遍更喜欢机器人：易用性、乐趣感、帮助性均显著提升超50%。
运动的物理特性使健身教练角色独特——他们能亲身示范动作、指导姿势并提供直观反馈。四足机器人同样具备实体形态和出色的敏捷性与运动能力。本文以跑步间歇训练为案例，研究四足机器人能否成为高效且令人愉悦的个人教练。我们提出SNOOPIE，一种可自主运行的四足跑步伴侣，能根据用户能力定制间歇训练任务。通过用户实验对比机器人与穿戴设备（如苹果手表），结果表明：使用机器人时，用户对节奏计划的遵守率提高60.6%，跑步速度一致性提升45.9%。主观评估显示，用户在易用性（+56.7%）、互动乐趣（+60.6%）和帮助性（+39.1%）方面均显著偏好机器人。更多视频与可视化内容见官网：https://sites.google.com/view/snoopie
原文摘要 · Abstract (English)
The physicality of exercise makes the role of athletic trainers unique. Their physical presence allows them to guide a student through a motion, demonstrate an exercise, and give intuitive feedback. Robot quadrupeds are also embodied agents with robust agility and athleticism. In our work, we investigate whether a robot quadruped can serve as an effective and enjoyable personal trainer device. We focus on a case study of interval training for runners: a repetitive, long-horizon task where precision and consistency are important. To meet this challenge, we propose SNOOPIE, an autonomous robot quadruped pacer capable of running interval training exercises tailored to challenge a user's personal abilities. We conduct a set of user experiments that compare the robot trainer to a wearable trainer device--the Apple Watch--to investigate the benefits of a physical embodiment in exercise-based interactions. We demonstrate 60.6% better adherence to a pace schedule and were 45.9% more consistent across their running speeds with the quadruped trainer. Subjective results also showed that participants strongly preferred training with the robot over wearable devices across many qualitative axes, including its ease of use (+56.7%), enjoyability of the interaction (+60.6%), and helpfulness (+39.1%).
