Neuralink 设计工程师 Ruse Madavian 分享他从设计 Apple Watch Siri 表盘到构建脑机接口的历程，探讨前沿界面如何需要从第一性原理重新思考交互。
Ruse Madavian, design engineer at Neuralink, shares his journey from designing the Siri watch face at Apple to building brain-computer interfaces, exploring how frontier interfaces require rethinking interaction from first principles.
要点 · TL;DR
脑机接口直接读取运动意图，绕过物理动作控制光标。 BCI reads motor intent directly, bypassing physical movement for cursor control.
设计脑机接口交互需要第一性原理思维，因为没有现成模型。 Designing BCI interactions requires first-principles thinking due to no existing models.
最终目标是通过直接读取高级意图来消除光标。 Ultimate goal is to eliminate cursor by directly reading high-level intent.
核心观点 · Key points
神经接口可以直接读取运动意图，绕过物理动作来控制光标。 Neural interfaces can directly read motor intent, bypassing physical movement for cursor control.
由于缺乏现有交互模型，设计脑机接口需要从第一性原理出发。 Designing for BCI requires first-principles thinking due to lack of existing interaction models.
点击的连续视觉反馈（如颜色、深度）提高了可预测性和用户学习效果。 Continuous visual feedback for clicks (e.g., color, depth) improves predictability and user learning.
参与者随时间与系统共同适应，通过练习提升表现。 Participants co-adapt with the system over time, improving performance through practice.
最终目标是直接读取高层次意图，从而消除光标。 The ultimate goal is to eliminate the cursor by directly reading high-level intent.
语音输入和停车位等无障碍功能对满足多样化用户需求至关重要。 Accessibility features like voice input and parking spots are crucial for diverse user needs.
反共识 · Contrarian takes
对运动障碍用户的共情有限；设计师无法完全想象他们的体验。 Empathy for users with motor disabilities is limited; designers cannot fully imagine their experience.
脑机接口的光标设计必须补偿缺乏物理反馈（如摩擦和压力）的问题。 Cursor design for BCI must compensate for lack of physical feedback like friction and pressure.
为不同交互（如拖拽、滚动）切换模式是当前必要的权衡。 Mode switching for different interactions (e.g., drag, scroll) is a necessary trade-off for now.
为一位参与者设计的停车位功能，在所有用户中变得流行。 The parking spot feature, designed for one participant, became popular among all users.
解码完整手臂运动比光标运动更难，尽管更直观。 Decoding full arm movements is harder than cursor movements, despite being more intuitive.
视觉假体如Blindsight将从低保真度开始，类似于雅达利图形。 Visual prosthetics like Blindsight will start with low fidelity, akin to Atari graphics.
