A method for carrying out a game of the type comprising the steps of noting written information on a surface with the aid of a writing means. The surface is provided with a position-coding pattern and the writing means is a combined writing and reading unit, which continually reads its movement across the surface. The information is converted into transmittable data and is sent via a communication system to a recipient which returns feedback on the received information.
A method of communicating with an electronic device. The method includes providing an electronic device having an audible sound receiving and generating sub-system including a microphone, transmitting from a source at least one acoustic signal encoded with information, receiving said at least one acoustic signal by said microphone and determining a spatial position, distance or movement of the microphone relative to the source, responsive to the received at least one signal.
A plurality of individual toys, at least a first one of which generates acoustic signals and at least a second one of which receives acoustic signals. When the second toy receives acoustic signals from the first toy, it responds, for example, by generating a sound and/or controlling its motion. In a preferred embodiment of the invention, the toys flock and/or form a procession of toys which follow a leader toy, for example a mother goose and a plurality of following and preferably quacking goslings.
