The ability to manipulate a remote object or environment is an important aspect for some telepresence users and can be implemented in a large number of ways depending on the needs of the user. Typically, the movements of the user's hands (position in space, and posture of the fingers) are sensed by wired gloves, inertial sensors, or absolute spatial position sensors. A robot in the remote location then copies those movements as closely as possible. This ability is also known as teleoperation.
