    Abstract: Examples disclosed herein provide an accessory device for a computing device. The accessory device can include a first section, a second section, and a third section. The first section can include one or more input devices. The second section can be pivotally connected to the first section at a first end of the second section. The third section can be pivotally connected to the second section at a second end of the second section. The protective cover can include a connector to electrically couple the input devices with the computing device when the connector is to connect with a port of the device. Motion sensors disposed within the accessory device can be used to determine an angle of the computing device with respect to the accessory device.
