Abstract: Device, system, and method of dynamic route guidance. For example, a method includes: calculating an optimal route from a first location, in which a navigation device is located, to a destination point entered by a user of said navigation device; receiving from the navigation device a travel update, indicating that the navigation device is located in a second location, wherein the second location is on said optimal route; and based on real-time traffic information and real-time road information, determining that an alternate route, from the second location to the destination point, is now an optimal route to the destination point.

Abstract: A displacement detection method for a portable autonomous device having an integrated image sensor. The method comprises several steps. In the first step a current digital image is received from the image sensor; the current digital image depicting a background scene. Then, the position of a first area within the current digital image is chosen. Afterwards, a later digital image is received from the image sensor depicting an overlapping portion of the background scene. Then, the position of a second area matching to the first area within the later digital image is identified. After a match has been identified, the first and second areas depict approximately the same portion of the background scene. Then, a current motion vector of the portable autonomous device is calculated, according to a displacement between the first area and the second area.

Abstract: An autonomous handheld device comprises a drawing module having drawing capabilities for electronically editing a drawing and a motion sensing feature for sensing self-motion. The autonomous handheld device is configured to associate the motion sensing feature with the drawing capability thereby to allow sensed motion of the motion sensing feature to modify the electronic editing.

Abstract: A device for converting digital images taken along a predefined movement pattern into a control signal. The device comprises an image input device having a connection to a image sensor. The image input device is adapted to receive the digital images captured during the displacement of the image sensor and determine whether motion measured therein corresponds to any prestored movement pattern, that is to say to a predefined gesture. The device further comprises a movement pattern converter to convert the recognized pattern into the control signal.
