    Abstract: Techniques for controlling a touch input device using an accessory communicatively coupled to the device are disclosed. In one aspect, an accessibility framework is launched on the device. An accessory coupled to the device is detected. Receipt of input from the accessory is enabled. An accessibility packet is received from the accessory. The accessibility packet includes an accessibility command and one or more parameters. The accessibility packet is processed to extract the first accessibility command and the one or more parameters. Input is generated for the accessibility framework based on the accessibility command and the one or more parameters. In some implementations, the device also sends accessibility commands to the accessory, either in response to accessibility commands received from the accessory or independent of any received accessibility commands.
