A method comprising: presenting a three-dimensional environment, comprising routes, to a user by using a selected one of a plurality of perspective views of the environment that corresponds to a current position on a current route; detecting a gesture user input comprising a characteristic that changes in time, and changing the current position on the current route to a new position on a route in response to the gesture user input wherein a first characteristic of the gesture user input determines a direction along the current route of the new position relative to the current position and a second characteristic of the gesture user input determines the new position; and presenting the three-dimensional environment, comprising routes, to the user by using a newly selected one of the plurality of perspective views of the environment that corresponds to the new position. |
