Abstract:
1. An apparatus comprising: a single actuator configured to provide vibrational movement of the apparatus in a first plane or having a component in the first plane; a direction indicator configured to indicate to a user a direction from the apparatus to a location of interest, wherein the location of interest identifies at least one of: a location of a source of an incoming communication, or a location of a destination of an outgoing communication; a processor configured to control the single actuator to align an axis of the apparatus with the direction; and a plurality of traction parts each configured to support a portion of the apparatus on a surface, a plane of the surface being perpendicular to the first plane, the traction part being configured to transform the vibrational movement of the apparatus into movement of the portion of the apparatus in the direction along the surface, the direction of the movement being predetermined by an orientation of the traction part; wherein the plurality of traction parts are oriented to provide net rotational movement of the apparatus about a center of rotation in response to the single actuator, and wherein for each respective traction part of the plurality of traction parts the apparatus has a corresponding turning moment in response to the single actuator.
