Abstract
A toy has a base member, a motion-detecting element mounted on the base member and detecting the presence of a motion of an object in the vicinity of the toy and the absence of a moving object in the vicinity of the toy, an action-performing element mounted on the base member for cooperating with the motion-detecting element, and electrical elements connecting the motion-detecting element and the action-performing element whereby the latter is operated in response to the detection by the motion-detecting element, wherein the motion-detecting element includes an objective arranged to transmit light to establish an image of an object in the vicinity of the toy, an image-distorting element located after the objective as considered in direction of light passage and arranged to distort the image, and a photosensing element arranged to sense the distorted image and produce a signal for operation of the action-performing element.
