我们提出牛顿的笔，一个静力学导师实现的“掌上电脑”，一个集成的数字化仪和嵌入式处理器的书写工具。这位针对本科教育的导师指导学生构建自由体图和平衡方程。这个项目需要草图理解技术和用户界面原则的发展，创造教学健全的教学工具，为笔记本电脑。由于有限的计算资源和视觉上静态的纸上墨水显示（唯一的动态输出设备是音频扬声器），在pentop平台上的开发提出了新的挑战。我们表明，基于有限状态机的系统架构降低了计算复杂度，并作为一种方便的手段，提供上下文敏感的教程帮助。我们的初步研究表明，牛顿笔有潜力作为一种有效的教学工具。
We present Newton's Pen, a statics tutor implemented on a "pentop computer", a writing instrument with an integrated digitizer and embedded processor. The tutor, intended for undergraduate education, scaffolds students in the construction of free body diagrams and equilibrium equations. This project entailed the development of sketch understanding techniques and user interface principles for creating pedagogically-sound instructional tools for pentop computers. Development on the pentop platform presented novel challenges because of limited computational resources and a visually static, ink-on-paper display (the only dynamic output device is an audio speaker). We show that a system architecture based on a finite state machine reduces the computational complexity, and serves as a convenient means for providing context-sensitive tutorial help. Our pilot study suggests that Newton's Pen has potential as an effective teaching tool.
