越来越多的消费产品包括依赖触摸输入的用户界面。虽然 3D 打印等数字制造技术可以更轻松地制作定制设备形状的原型，但为此类原型添加交互性仍然是许多设计师面临的挑战。我们推出 Midas，这是一个软件和硬件工具包，用于支持交互式对象的柔性电容式触摸传感器的设计、制造和编程。借助 Midas，设计人员首先在传感器编辑器中定义所需的形状、布局和触摸敏感区域的类型，以及路由障碍物。根据此高级规范，Midas 自动生成具有适当传感器焊盘和路由连接的布局文件。然后使用这些文件通过数字制造工艺（例如乙烯基切割机和导电墨水打印机）来制造传感器。使用 Midas 生成的分步组装指令，设计人员将这些传感器连接到 Midas 微控制器，该微控制器检测触摸事件。一旦组装好原型，设计人员就可以定义传感器的交互性：Midas 支持用于控制现有本地应用程序的记录和重放操作，以及用于控制新颖或远程应用程序的基于 WebSocket 的事件输出。在三名参与者的首次使用研究中，用户成功制作了媒体播放器原型。我们还演示了如何使用 Midas 来创建许多触摸感应界面。
An increasing number of consumer products include user interfaces that rely on touch input. While digital fabrication techniques such as 3D printing make it easier to prototype the shape of custom devices, adding interactivity to such prototypes remains a challenge for many designers. We introduce Midas, a software and hardware toolkit to support the design, fabrication, and programming of flexible capacitive touch sensors for interactive objects. With Midas, designers first define the desired shape, layout, and type of touch sensitive areas, as well as routing obstacles, in a sensor editor. From this high-level specification, Midas automatically generates layout files with appropriate sensor pads and routed connections. These files are then used to fabricate sensors using digital fabrication processes, e.g., vinyl cutters and conductive ink printers. Using step-by-step assembly instructions generated by Midas, designers connect these sensors to the Midas microcontroller, which detects touch events. Once the prototype is assembled, designers can define interactivity for their sensors: Midas supports both record-and-replay actions for controlling existing local applications and WebSocket-based event output for controlling novel or remote applications. In a first-use study with three participants, users successfully prototyped media players. We also demonstrate how Midas can be used to create a number of touch-sensitive interfaces.
