A method for producing an output in response to an interaction with a print element on a sheet is disclosed. In one embodiment, the method includes placing a sheet comprising a print element on a surface of a base unit. A user can then mark on the sheet in the vicinity of the print element with a marking instrument. An audio output that corresponds to the print element is generated.

Interactive apparatus using print media

A peripheral interface device for determining the color of a surface, where the surface color may then be used to determine device position and identify objects. Embodiments provide a device capable of directing different colors of light (e.g., red, green and blue) onto a surface and measuring relative intensities of the reflected colors to determine the color of the surface. The reflection and measurement of each color may be performed separately. Alternatively, composite-colored light may be directed at the surface, which may then be filtered to extract the different colors and enable measurement of their relative intensities. As such, the device can detect regions of a given color and regions of different shades of the same color, which may then be used to determine the position of the device and/or identify an object.

Peripheral interface device for color recognition

A magnetic switch and children's apparatuses, such as print media apparatuses and plush dolls, which include magnetic switches are disclosed. One magnetic switch includes a first conductor and a second conductor spaced apart from the first conductor. A third conductor is disposed under the first and second conductors, the third conductor being formed from a magnetic material. A magnet is also included, the magnet being adapted to move the third conductor towards the first and second conductors so as to form a conductive bridge. Another magnetic switch includes a first conductor and a second conductor spaced apart from the first conductor. A first magnet is disposed under the first and second conductors. A second magnet is also included, the second magnet being adapted to move the first magnet so that the first and second conductors form a conductive bridge.

Magnetic switch and apparatus including magnetic switch

A three-dimensional position locating system is disclosed. In one embodiment, the three-dimensional position locating system includes a housing including a substantially planar surface. The housing includes a first antenna element under the substantially planar surface. A stylus including a second antenna element is coupled to the housing. A processor is electrically coupled to the first antenna element and the second antenna element, and a three-dimensional structure overlies the first antenna element. An antenna coupling element is associated with the three-dimensional structure and an output device can be coupled to the processor.
