This plugin adds support for HID devices like tablets, gamepads and car wheels. The package will provide three layers to the plugin:Concrete class layer - This layer represents real devices as Smalltalk objects. For example, the HIDTablet class provides access to a real tablet connected to an USB port to which Smalltalk messages can be sent.Class library layer - The class hierarchy is used to query the devices to retrieve their capabilities and encapsulate the internal pointers and C structures into Smalltalk objects.Low level layer - HIDPlugin is a low level wrapper for Apple's HID Utilities library.Acompiled versionof the plugin is available.
