Abstract:
1. A base station for use in generating first data that is indicative of at least two positional coordinates of an enclosure relative to the base station, said first data being dependent on a first output signal generated by a position sensing device coupled to a first communication device that is configured to generate said first data, the enclosure being separate from the base station and designed to be handheld by a user and operated by the user in mid-air, the position sensing device comprising components contained in at least one of said base station and said enclosure, the base station comprising: a level sensing device for generating a second output signal that is sensitive to an angle of the base station relative to gravity; at least one of a first power source and a connection to an external second power source for providing power to devices in the base station; and a second communication device coupled to said level sensing device and configured to generate second data that is dependent on said second output signal; wherein the enclosure includes: wherein the first, second and third communication devices are configured to be coupled to a fourth communication device that is coupled to said processing unit and is for supplying fourth data to the processing unit, the fourth data being dependent on at least one of the first data and the second data and the third data; and wherein the processing unit is coupled to a non-transitory computer-readable medium or media storing computer-executable instructions for causing the processing unit to perform a method, the method comprising the steps of:
