Abstract
Methods and apparatus for allowing a user to switch viewing positions and/or perspective while viewing an environment, e.g., as part of a 3D playback/viewing experience, are described. In various embodiments images of the environment are captured using cameras placed at multiple camera positions. During viewing a user can select which camera position he/she would like to experience the environment from. While experiencing the environment from the perspective of a first camera position the user may switch from the first to a second camera position by looking at the second position. A visual indication is provided to the user to indicate that the user can select the other camera position as his/her viewing position. If a user input indicates a desired viewing position change, a switch to the alternate viewing position is made and the user is presented with images captured from the perspective of the user selected alternative viewing position.
