致谢与许可
最后更新：2026 年 10 月 21 日
Smashphone 建立在许多人愿意分享的成果之上。这一页把它们列出来：球员挥拍用的动作捕捉、球员人物、乒乓球的公园，以及 App 里的软件。适用于 iPhone 与 Apple Watch 版 Smashphone 1.5.0。
许可要求随作品附上的版权声明和许可全文，见许可原文。论文和许可原文保留英文，以原文为准。
1. 球员动作

Smashphone 的四个球类一共用了其中 108 个击球动作。我们做的改动：每个片段是从一段录制里切出的一次击球，从数据集的骨架重定向到我们的球员身上，并标出拍子触球的那一刻。比赛中这些片段会被实时混合和调整，比如为了够到球。
改编后的片段按同样的许可分享。Smashphone 由 Tennis-MoCap 改编的 108 个动作片段按 CC BY-SA 3.0 许可。可以下载一个 ZIP，里面是 JSON 文件和一份说明出处与改动的 README；每个文件也写着自己出自哪段录制和许可。这一许可只适用于这些片段，不适用于 App 的其他部分。

Scientific Data, 11. doi:10.1038/s41597-024-03144-z。按 CC0 1.0 贡献到公有领域。Smashphone 用了其中 18 个击球动作，主要在羽毛球里。CC0 不要求署名，我们仍然在这里致谢。
2. 球员人物
Microsoft Rocketbox Avatar Library，github.com/microsoft/Microsoft-Rocketbox，MIT 许可，Copyright (c) 2020 Microsoft。球员用的是 Sports_Male_04 这个角色，头部和肤色取自 Male_Adult_10。我们加了前臂扭转骨，让手握住拍柄，并给两边的球员换了背心颜色。
