Abstract
An extended keyboard includes keys and conductive contact points. Each key is connected to a corresponding one or more conductive contact points. The conductive contact points protrude from a backside of the extended keyboard. The conductive contact points are used to contact with a multi-point touch screen of an electronic device when the extended keyboard is placed on the multi-point touch screen of the electronic device, such that when an operation is applied to one key, the corresponding one or more conductive contact points electrically connected to the key conduct the operation to positions of the multi-point touch screen contacted with the corresponding conductive contact points.
