Method, apparatus and computer program for user control of a state of an apparatus

A method comprising:

• enabling a first user gesture detector, wherein the first user gesture detector comprises a touch sensitive device configured to detect touch on a two-dimensional surface;
• enabling a second user gesture detector;
• switching between operating in a two-dimensional user interface state and operating in a three-dimensional user interface state only after the first detector has detected a predefined first phase of a predefined user gesture and the second detector has detected the predefined second phase of the predefined user gesture;
• wherein enabling the second detector comprises:
• switching on the second detector or adjusting the second detector from a lower energy consumption mode to a higher energy consumption mode, and wherein enabling the second detector is responsive to detecting, using the first detector, the predefined first phase of the predefined user gesture;
• and
• wherein the predefined first phase of the predefined user gesture comprises movement substantially in a first plane and wherein the predefined second phase of the predefined user gesture comprises movement substantially outside of the first plane.

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code,
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to enable:
