A control devices includes a key having a top surface configured to be pressed by a user, and a resistance device coupled to the key and configured to provide a resistance force to the key that opposes a user force applied to the top surface. A force sensor is coupled to the resistance device and is configured to detect the user force applied to top surface. A control circuit is coupled to the resistance device and is configured to change the resistance force of the resistance device according to a force profile.
