这两年对Open Source Hardware有点兴趣,不过也只是限于了解一丁点而已。知道 EyeWriter 是今天看到了TED分享–Mick Ebeling: The invention that unlocked a locked-in artist。这是个开源装置——是为了解决神经疾病ALS(肌肉萎缩性脊髓侧索硬化症)病人的表达问题而诞生的。

EyeWriter 的项目网址是:http://www.eyewriter.org/diy/

制作步骤可以参见:Instructables 网站的指引–英文

The EyeWriter software is two parts — an eye-tracking software designed for use with our low-cost glasses, and a drawing software designed for drawing with eye movements. The source code for the project is currently being hosted at: https://github.com/eyewriter. The software for both parts has been developed using openframeworks, a cross platform c++ library for creative development. In order to compile and develop the EyeWriter source code, you will need to download openframeworks (pre release v0.06). Documentation, setup guides and more information can be found at http://openframeworks.cc.

EyeWriter 的软件用到了 GSL (GNU Scientific Library) https://github.com/LuaDist/gsl 也是头一次听说。

要是,这个设备不用接电脑,做成手机应用,配合音频口数据通信技术(Data Transfer over Audio Port),整个系统应该能做得更轻量级。
