A position detection system for use in association with computing applications is disclosed. The position detection system comprises at least one positional element for attaining a position and a positioning device operative to determine a position of the positional element. The positional element comprises at least one first emitter for emitting a substantially continuously modulated acoustic waveform decodable to fix the position, and a second emitter for emitting a synchronization signal. The positioning device comprises an arrangement of at least one of a first detector operative to detect the continuously modulated acoustic waveform in a manner permitting fixing of the position and outputting the waveform for computation, in a manner retentive of the position fixing ability and a second detector operative to detect the synchronization signal. The synchronization signal is transmitted within a time frame having a fixed duration and is continuously repeated. The time frame is known to the positioning element. The synchronization signal is a sequence of at least two synchronization sub-signals. Each synchronization sub-signal bears timing data for the continuously modulated acoustic waveform, thereby to improve accuracy of the fixing of the position. The at least two synchronization sub-signals allow the at least one positional element to derive clock synchronization data by correlating the timing data and the known time frame duration.
