Abstract: A self-propelled device determines an orientation for its movement based on a pre-determined reference frame. A controller device is operable by a user to control the self-propelled device. The controller device includes a user interface for controlling at least a direction of movement of the self-propelled device. The self-propelled device is configured to signal the controller device information that indicates the orientation of the self-propelled device. The controller device is configured to orient the user interface, based on the information signaled from the self-propelled device, to reflect the orientation of the self-propelled device.

Abstract: A self-propelled device is provided including a drive system, a spherical housing, and a biasing mechanism. The drive system includes one or more motors that are contained within the spherical housing. The biasing mechanism actively forces the drive system to continuously engage an interior of the spherical housing in order to cause the spherical housing to move.

Abstract: A self-propelled device operates to interpret an input corresponding to a set of actions that are performed on a controller device.

Abstract: A self-controlled device maintains a frame of reference about an x-, y- and z-axis. The self-controlled device processes an input to control the self-propelled device, the input being based on the x- and y-axis. The self-propelled device is controlled in its movement, including about each of the x-, y- and z-axis, based on the input.

Abstract: A system for controlling a self-propelled device in connection with a virtual environment in which the self-propelled device is represented.
